If I can help out in any way with the restoration lemme know, Neil! I have had several of these pass through my hands now, and currently own a nice working Model 3. Along with lots of documentation, hard drive contents, software on disk, peripherals and so on. The main thing I don’t have is that Sega CRT, those can go for similarly insane prices as the system itself!
@@RMCRetro This video has misinformation in it. There was a United States release, but it was in a different PC case. It was a beige box PC with a sliding door for the MegaDrive/ Genesis system instead of the flap on your PC.
@@weltschmerz88 no I am thinking of the SEGA PC. Basically the same case, but thicker & included a CD-ROM drive. The computer was made by SEGA for the United States market on a 386 platform with Windows 3.0
I would've loved to hear that phone conversation. "Mega Drive, huh? Would that be a hard file, or high-capacity floppy? .... uh huh ... uh huh ... Uh, genesis of what, exactly? ... uh huh ... I'm sorry, I don't think I heard you correctly. Did you say 'hedgehog?' ... You did. .. Uh huh ... 'Tube?' ... OH, sorry, 'Tude.' ... Short for 'attitude.' ... I see. Well, to be perfectly honest, sir, I'm not sure what to suggest. We don't really do 'fun' around here. _Our_ mascot is a silent film actor. I'll see what I can do. I'm sure manufacturing could have a prototype for you in about ... three, four years...? For the chassis, do you prefer beige or cream? .... Uh huh. Well, that would be highly unusual."
Or maybe "Thank you! We've got so many we were about to throw awa--- er, we mean, sure, we want to sell these state-of-the-art pieces of hardware! Totally not obsolete tech!"
Considering that the entire PS/2 line was built to differentiate the hardware from generic PCs, i think they would have welcomed the opportunity if they didn't pitch the idea first.
I didn't even know the A500+ had an RTC in it, what's the battery for? I remember the first time I heard about this, I dug my A500+ out of the cupboard, opened it up, and found a pristine battery in there... and promptly snipped it off the motherboard.
I once briefly owned an A500 with an expansion board which had leaked so badly it not only ate through a connection but also reached the rear I/O connections, 'thankfully' I was able to return it.
I remember the Mega PC well. It was in all the main department stores in the UK in the early 1990s. It was highly desirable but out of the price range of anyone I knew.
The PC side using the YM2612 sound chip is so cool! The Mega Drive's FM chip is a legitimate powerhouse to the point there's a desktop synthesizer that uses two of those chips to generate sound. It's called the MEGAfm. If you look it up you'll see the huge variety of sounds it can make, it's still so relevant today.
What a good thing there are a few VSTs if you want to achieve a similar thing in your DAW and there is also the Sonicware Liven Mega Synthesis hardware groove box which I own and love and even a midi adapter for your Mega Drive!
I remember seeing these back in the ‘90s when I was living in Asia. I was around 9-10 yrs old and had an Mega Drive. Owning one was the ultimate dream at the time since PCs weren’t common for home use yet. I was familiar with PCs and DOS games because I saw them in the office where my dad worked. Back then, PCs were all beige, and most didn’t even have CD drives or sound cards yet. So, seeing such a modern-looking, cool black PC with a matching monitor made by Sega that could also play Sega cartridges was unreal.
Absolutely stunning piece of technology, i love seeing retro motherboard layouts. Back when chips took up most of the space on the board, nowadays the chips barely take up any room and most of the board is just silk screen.
Having owned a IBM PS/2 Model 30 286 (my 1st PC) and a SEGA Mega Drive at the same time back in the early 90s, this blows my mind! A combo of these two! Oh, you lucky devil Neil!
Back in the days there was this Sega-only magazine in Brazil called SuperGame, they release an article about the Tera Drive. 11 out of 10 people you show would have their minds blown, and as a kid we rightaway started thinking you'd be able to develop games for the Mega Drive and all sorts of crazy stuff. Good ole times...
I had an IBM PS2 keyboard for years and it eventually went the way of the swan. Was built like a tank! It was also quite noisy and used to wind up my housemate. 😃
The SMD caps on these IBM hard drives are prone to leaking, and it looks like yours is affected too. IIRC, you can access all of them without having to remove the HDA.
These keyboards rule! Built by Alps and uses Alps Buckling Spring. Similar to the IBM Buckling Spring but it uses a slider and buckles in a different direction

Thanks for sharing this video I didn't know it existed and it is really awesome concept. I will keep an eye out for part two and hope to see it working
Apparently Amstrad had an upgrade for the Mega PC called the Mega PC Plus, which used an 80486 processor and had a RAM upgrade. That's probably the rarest Megadrive PC.
As an interesting side note, Egyptian (ex Kuwaiti) company Al Alamiah also brought out the AX-660 and AX-990 in 1992. Both were MSX 1 computers even though MSX 2 and 2+ already existed. Both systems had integrated MegaDrive clones and you could switch between MSX mode and MegaDrive mode.
I've seen such a PC in France, it had a sliding part in front to hide either the cartridge slot or the floppy/cd drive. I don't remember which drive(s) it had. It seems people are looking for forgotten pieces and bits about these machines, so just in case, the one I saw was in a shop called nasa or tardy in early 90s, in the center of Strasbourg.
Years ago I was a proud owner of an Amstrad Mega-PC, a similar idea to this. It was simply and Amstrad 386 PC compatible computer with a sliding door on the front of the desktop unit. If you slid the door across to the right, you found a Megadrive cartridge slot. It came with a beige Sega controller, and the computer literally had nothing to do with the Megadrive bits. Neither part spoke to the other. It was two machines in one case essentially, and sliding the door cut off one part so you could use the other. Both outputted to the same monitor and speakers though. This was UK computer, and I wrote this before the Mega PC was displayed in the video.
Just for the sake of preservation (and maybe a dash of curiosity), I'd like to see a detailed scan and / or photo of the motherboard and other PCBs especially since this system seems to be more rare than hen's teeth and unicorn leavings combined.
Seeing a Sam Coupe in the background made me happy, while at the same time sad that my parents threw away my old one, with dev card and loads of software, when they moved years ago.. There's something about the Coupe that I really still love the look of.
Oh wow. I actually had one of these. A friend of mine gave it to me after his dad bought two back from a business trip in early 1992. It was very weird when, in 1993, the Mega PC from Amstrad came out.
Interesting to note at 3:33 that screenshot of Sonic 1 is from a prototype because its missing the s from "rings" and I think the flower sprite is slightly different.
I remembered when this first came out in Australia, It was a pathetic 286/16 then later models was a 386 which was 2 generations out of date of the current PC's for the same price. It was way cheaper to buy a 486/dx33 AND a MegaDrive separately.
12 years on UA-cam and I am just now finding your channel!? I feel cheated by the algo! Where is Sega or IBM on this? They should be helping us piece together their history...
Very timely...i recently found my Mega PC which was bought from new, still in as-new condition and decided to restore it. Currently battling a possible faulty onboard WDC FD controller (very common in IBM conpatibles at the time) which is preventing booting up with the HDD.
I had something similar as a kid, I think it was the megaPC, maybe by amstrad, is was a dos computer and a megadrive. It was my first introduction to PC gaming and it shaped my life so much! I am so happy I had that system
Saw one on sale as a kid, in 1997, but seeing as I was on holiday it would have been impossible to haul back. I was 12 and here I see people not knowing about this, 30 years later, to my great surprise. I wish more people would have paid attention back then, like a few of us did, when it came to games :(
Based on a PS/2 Model 30/286? That would suggest that you should be able to use a modern drive with an XT-CF (which I actually do), but it doesn't look to have the three ISA slots the original PS/2 had.
Aside from the hard drive, I don't see anything in common with the 30-286. But it seems some of the planar logic was reused from the Japanese PS/55 5510.
@@fnjesusfreak The 8530 286 was available with at least 3 hard drive sizes - 20, 30, and 45 MB. If I'm not mistaken the 30 MB one was the same WDL-330PS used in this unit.
It should be pointed out that the 286 cpu used in the TerraDrive is a 2nd gen one from 1985 rather than a 1st gen 1982 286. There is a tendency for people to conflate early PC CPUs but usually there were 2 or 3 generations of each chip. The original 1982 286s were either 5, 6 or 8 MHz and the 2nd gen 1985 ones were much faster at 10 or 12.5mhz. As Intel shifted to 386 production, AMD and Harris released 16, 20 and 25 MHz 286s which were basically equal in performance to a 386SX at the same clock. 486s first came out in 1989 but it wasn't until 1991 that they had dropped enough in price to be really found in home builds so fast 286s and 386SXs were still very common for budget home setups. These PCs would have been fine running most software up until 1993 at which time 486s and the new Pentiums started to completely take over.
it's often overlooked how long the cpu gens were sold as lower end offerings. 1991 home 486 was still very, very rare and you could still buy a 8mhz xt. but then again you could still buy a new c64 too in 1991.
Thank you for doing this deep dive. Love seeing these obscure hardwares get proper documentation. Couple questions: 1. If you rigged up a custom ribbon cable of sorts, does a Mega CD actually work on it? 2. Based on all the motherboard revisions of the Mega Drive, which VA would be most analogous to this? 3. Would a 32X work with it too?
1: Someone has already tried it and the answer is... Yes! 2: I would say a late model 1 or so. 3: No. Even if you removed all the plastic surrounding the unit, the pass-though cables needed wouldn't be able to be hooked up to a VGA CRT even with adapters all the way down.
Back in late 80's I used to see Sugar on the first Liv St to Brentwood trains in the morning and even spoke to him a couple of times, utterly obnoxious man who used to sit near old ladies on the train and light up his toxic cigars for fun... wreathing the poor target in clouds of smoke and he played a vicious smirk when coughing the old 'un was forced to move and he would follow them around the train... Asked my BR dad why he never got nicked for smoking in a no smoking carriage and old man came back saying "he seems to have paid for the privilege..." suggesting someone on BR got a major bung in their sky rocket to allow him to light up anywhere where lesser folks like myself would have been ripped a new one finewise if I dared do likewise.
That's a beautiful bit of kit . U would have to be well rich to have had one of them back in the day , as usual amstrad tried to do something similar but about 2 years too late Can't wait for the next part
I've wanted one of these for decades now, I was a kid when they were relatively cheap online (couple hundred max), now they're impossible to find under thousands.
As someone who followed this stuff closely back then, the TeraDrive name was in line with the GigaDrive, the original planned successor to the MegaDrive that rumours swirled around at the time. Things changed quickly back then. 286, though? Oof.
Wow, this is such a cool piece of kit. Knew of them but never actually seen one or even one shown in detail on a video. Really interesting, makes you think perhaps Sega should’ve gone into the gaming pc market?
I remember seeing ads for the Mega PC. I don't remember it being made by Amstrad, though. This Teradrive looks to be a much better product. Here's hoping you manage to get it up and running again
I heard of the TeraDrive back in the '90's. And I heard of the Amstrad Mega PC around the same time. I wanted one of either, I didn't care. It didn't matter that I had a PC that was probably powerful than either combo-computer. I was a Sega kid growing up. Just thought it was cool to be able to play MD games on a PC.
Assuming the PC and MegaDrive hardware are able to interact (I haven't finished the video quite yet), this device would have made an awesome Devkit! Build the games and test them on the same device.
I saw a Teradrive in Akihabara over ten years ago. I don’t remember how much it was, but I remember it being affordable for me at the time (I wasn’t making much) but I didn’t have the space for it
I remember first discovering this out of random during when I starting to collect for the Genesis and looking up what good game are available and founded this out of nowhere. Although something worth noting in regards to the Expansion slot, I remembered that someone did disassembled a Mega CD to get it working on the Terradrive. Idk if the video is still there or not.
the puzzle game is a pack in title included on the factory hard drive loadout, i have one of these and have that working, but ive also found a hard drive image for it that someone made since i had some trouble with my hard drive, it needed the caps replaced but works properly again, however i think it managed to corrupt some files since a few thing i try poke at crash the system
Obviously outside the scope of a museum, but it would be really interesting if it were possible to reverse engineer this and/or the Amstrad and see if it wouldn't be possible to make a 486 version of this concept. That would've been the ultimate early 90s machine.
I used to wonder what it would be to have console-grade 2D videocard in PC. What it would be to program console-grade games in Turbo Pascal. SEGA did not deliver that, however, there is NEC PC-FX GA videocard that supposedly delivers same graphics as NEC PCengine FX console. This is a very rare item. If I program it in Turbo Pascal, nobody could play that
@16:06 - I wonder, could you "PC-link" w/ a copy(ies) of Zero Tolerance (similarly to "console-linking" on a [sole] Genesis / Mega-Drive consoles, with the before-stated game)? 🤔 Also, looking forward to Part ✌😎!
The TeraDrive is nowadays a very desirable Sega console. As you mentioned, the capacitors are the main issue with a 30 years old computer/console. Despite that it is for sure a great rare item to get in your collection.
Remember reading about this back then, thought it sounded cool, but wondered how often the average PC user, who wasn't really into games at that time, would be firing up a cartridge game.
I have never understood why these exist. Devices like this always seem to be compromised versions of their standalone parts, that usually cost more than buying the normal halves separately. Shockingly, they're almost never popular in the market. Interesting video nonetheless. :-) Good luck getting it working!
has a similar aesthetic to the 68k - love it! can't wait to see it turned on - i always wondered the level of integration but even japanese language sites are short on information

Seeing a Sam Coupe in the background made me happy, while at the same time sad that my parents threw away my old one, with dev card and loads of software, when they moved years ago..
There's something about the Coupe that I really still love the look of.
Oh wow. I actually had one of these. A friend of mine gave it to me after his dad bought two back from a business trip in early 1992. It was very weird when, in 1993, the Mega PC from Amstrad came out.
Interesting to note at 3:33 that screenshot of Sonic 1 is from a prototype because its missing the s from "rings" and I think the flower sprite is slightly different.
What a brilliant video! Never heard of it and really enjoyed this!!
Getting distracted by the SAM Coupe lurking in the cabinet ...
I remembered when this first came out in Australia, It was a pathetic 286/16 then later models was a 386 which was 2 generations out of date of the current PC's for the same price. It was way cheaper to buy a 486/dx33 AND a MegaDrive separately.
12 years on UA-cam and I am just now finding your channel!? I feel cheated by the algo! Where is Sega or IBM on this? They should be helping us piece together their history...
Nice! What a fun watch! I guess I found a new channel to chill out to!
New "trash to treasure" on a long weekend? Yes please! Thanks Neil :)
I would totally build a modern gaming PC in one of those cases.
Very timely...i recently found my Mega PC which was bought from new, still in as-new condition and decided to restore it. Currently battling a possible faulty onboard WDC FD controller (very common in IBM conpatibles at the time) which is preventing booting up with the HDD.
Now you are missing the SEGA A.I. Computer.
I had something similar as a kid, I think it was the megaPC, maybe by amstrad, is was a dos computer and a megadrive. It was my first introduction to PC gaming and it shaped my life so much! I am so happy I had that system
oh, you mention it later, yeah it was that!
Saw one on sale as a kid, in 1997, but seeing as I was on holiday it would have been impossible to haul back. I was 12 and here I see people not knowing about this, 30 years later, to my great surprise. I wish more people would have paid attention back then, like a few of us did, when it came to games :(
Based on a PS/2 Model 30/286? That would suggest that you should be able to use a modern drive with an XT-CF (which I actually do), but it doesn't look to have the three ISA slots the original PS/2 had.
Aside from the hard drive, I don't see anything in common with the 30-286. But it seems some of the planar logic was reused from the Japanese PS/55 5510.
@@GeckonCZ Not even the hard drive, that was a 20 MB unit in the 30/286.
@@fnjesusfreak The 8530 286 was available with at least 3 hard drive sizes - 20, 30, and 45 MB. If I'm not mistaken the 30 MB one was the same WDL-330PS used in this unit.
It should be pointed out that the 286 cpu used in the TerraDrive is a 2nd gen one from 1985 rather than a 1st gen 1982 286. There is a tendency for people to conflate early PC CPUs but usually there were 2 or 3 generations of each chip. The original 1982 286s were either 5, 6 or 8 MHz and the 2nd gen 1985 ones were much faster at 10 or 12.5mhz. As Intel shifted to 386 production, AMD and Harris released 16, 20 and 25 MHz 286s which were basically equal in performance to a 386SX at the same clock. 486s first came out in 1989 but it wasn't until 1991 that they had dropped enough in price to be really found in home builds so fast 286s and 386SXs were still very common for budget home setups. These PCs would have been fine running most software up until 1993 at which time 486s and the new Pentiums started to completely take over.
it's often overlooked how long the cpu gens were sold as lower end offerings. 1991 home 486 was still very, very rare and you could still buy a 8mhz xt.
but then again you could still buy a new c64 too in 1991.
@@lasskinn474 You could buy a new C64 all the way up until Commodore folded in '94.
Thank you for doing this deep dive. Love seeing these obscure hardwares get proper documentation. Couple questions:
1. If you rigged up a custom ribbon cable of sorts, does a Mega CD actually work on it?
2. Based on all the motherboard revisions of the Mega Drive, which VA would be most analogous to this?
3. Would a 32X work with it too?
1: Someone has already tried it and the answer is... Yes!
2: I would say a late model 1 or so.
3: No. Even if you removed all the plastic surrounding the unit, the pass-though cables needed wouldn't be able to be hooked up to a VGA CRT even with adapters all the way down.
An IBM, PS2 and Mega Drive? I'm in!
Back in late 80's I used to see Sugar on the first Liv St to Brentwood trains in the morning and even spoke to him a couple of times, utterly obnoxious man who used to sit near old ladies on the train and light up his toxic cigars for fun... wreathing the poor target in clouds of smoke and he played a vicious smirk when coughing the old 'un was forced to move and he would follow them around the train... Asked my BR dad why he never got nicked for smoking in a no smoking carriage and old man came back saying "he seems to have paid for the privilege..." suggesting someone on BR got a major bung in their sky rocket to allow him to light up anywhere where lesser folks like myself would have been ripped a new one finewise if I dared do likewise.
It's in great hands. Sega had one of these on display at SegaFes 2018 in Tokyo, so cool!
Part 2 suggestion: It would be nice to hear a short description of how the 3 CPUs (286, 68000, Z80) differ in terms of CPU architecture.
Can we talk about the design of this machine? That front panel has such a sleek and sexy look.
This was a PC I'd have sold my soul for as a kid!
I wish they hadn't restriced this to Japan. I would have been interested at the time. It's perfect for me yet I hever heard of it.
thanks for a great video!, hope part 2 comes soon
14:36 "Factory fitted patch wires" is a nice way of saying "Bodge Wires" ☺
Overcharging for crap hardware is what IBM excelled at in those days.
That's a beautiful bit of kit . U would have to be well rich to have had one of them back in the day , as usual amstrad tried to do something similar but about 2 years too late
Can't wait for the next part
I've wanted one of these for decades now, I was a kid when they were relatively cheap online (couple hundred max), now they're impossible to find under thousands.
As someone who followed this stuff closely back then, the TeraDrive name was in line with the GigaDrive, the original planned successor to the MegaDrive that rumours swirled around at the time. Things changed quickly back then.
286, though? Oof.
An utterly, utterly fascinating machine.
I picked the best time to become a Patreon :D
I'm extremely curious if you could jerry-rig a Sega CD to work with this thing using a homemade ribbon cable and that expansion port.
Wow, this is such a cool piece of kit. Knew of them but never actually seen one or even one shown in detail on a video. Really interesting, makes you think perhaps Sega should’ve gone into the gaming pc market?
@13:50 - I remember these rails. IBM used those in their PS/ValuePoint PCs... Maybe my toys in the attic playing tricks again.
I remember seeing ads for the Mega PC. I don't remember it being made by Amstrad, though. This Teradrive looks to be a much better product. Here's hoping you manage to get it up and running again
So cool! Very excited for this series.
I’m aware of the Amstrad MegaPC, which is basically the same thing but the Teradrive is new to me? Thanks @RMCRetro
Really interesting system. I look forward to part 2.
I heard of the TeraDrive back in the '90's. And I heard of the Amstrad Mega PC around the same time. I wanted one of either, I didn't care. It didn't matter that I had a PC that was probably powerful than either combo-computer. I was a Sega kid growing up. Just thought it was cool to be able to play MD games on a PC.
Assuming the PC and MegaDrive hardware are able to interact (I haven't finished the video quite yet), this device would have made an awesome Devkit! Build the games and test them on the same device.
I saw a Teradrive in Akihabara over ten years ago. I don’t remember how much it was, but I remember it being affordable for me at the time (I wasn’t making much) but I didn’t have the space for it
Amazing... It's so clean inside without case rusting (excluding PSU)
Was it so damn hard to release a PC with relevant specs? A 286 in 91 was just failure waiting. I'd have loved this as a 486. It's beautiful
I remember first discovering this out of random during when I starting to collect for the Genesis and looking up what good game are available and founded this out of nowhere. Although something worth noting in regards to the Expansion slot, I remembered that someone did disassembled a Mega CD to get it working on the Terradrive. Idk if the video is still there or not.
the puzzle game is a pack in title included on the factory hard drive loadout, i have one of these and have that working, but ive also found a hard drive image for it that someone made since i had some trouble with my hard drive, it needed the caps replaced but works properly again, however i think it managed to corrupt some files since a few thing i try poke at crash the system
Wow, I was just reading an old issue of EGM from late 90 that had mentioned this was in the works. I'm here because I wanted to learn more about it.
Obviously outside the scope of a museum, but it would be really interesting if it were possible to reverse engineer this and/or the Amstrad and see if it wouldn't be possible to make a 486 version of this concept. That would've been the ultimate early 90s machine.
I used to wonder what it would be to have console-grade 2D videocard in PC. What it would be to program console-grade games in Turbo Pascal. SEGA did not deliver that, however, there is NEC PC-FX GA videocard that supposedly delivers same graphics as NEC PCengine FX console. This is a very rare item. If I program it in Turbo Pascal, nobody could play that
@16:06 - I wonder, could you "PC-link" w/ a copy(ies) of Zero Tolerance (similarly to "console-linking" on a [sole] Genesis / Mega-Drive consoles, with the before-stated game)? 🤔 Also, looking forward to Part ✌😎!
The TeraDrive is nowadays a very desirable Sega console. As you mentioned, the capacitors are the main issue with a 30 years old computer/console. Despite that it is for sure a great rare item to get in your collection.
It’s not in his collection, it’s on loan.
30mb hdd? Wow. When I added a 10mb to my 286 it was life changing. Triple that sounds like so much!
Remember reading about this back then, thought it sounded cool, but wondered how often the average PC user, who wasn't really into games at that time, would be firing up a cartridge game.
It sure is pretty. I’d absolutely love to play MegaCD Lunar on this in a room full of cigarette smoke and laserdiscs.
🎵SEGA🎵
Ah that crunchy sample that fills ones heart with joy to this day.
Wonder how many office executives were able to sneak this in as a company purchase for their office and were playing sonic at work
I have never understood why these exist. Devices like this always seem to be compromised versions of their standalone parts, that usually cost more than buying the normal halves separately. Shockingly, they're almost never popular in the market.
Interesting video nonetheless. :-) Good luck getting it working!
Really cool machine ... Looking forward to part 2 :)
has a similar aesthetic to the 68k - love it! can't wait to see it turned on - i always wondered the level of integration but even japanese language sites are short on information
Also, the SMD caps on the drive will start to leak at some point for sure, they all do on that kind of drive.
12:08 that 8 bit soundcard alone is worth like $2-300 on eBay.
nice, i saw the sc-3000 in your lineup
5:05 that IBM quip made me literally laugh out loud!
That is an awesome looking computer!
Gorgeous machine. Inside and out.
with some expected sega jankiness
