- In this video I take a look at the awesome Z80 based RC2014 computer kit. This kit is throwback to microcomputers of the 70's and 80's. It pays homage to kit computers such as the Altair 8800 and microcomputers of the 80's. The base Pro kit comes with the backplane, Z80 CPU card, 64K RAM card, Dual SIO card, Pageable ROM card, CF card and clock and reset card.

I love my RC2014. Classic II specifically, though I have 2/3 boards from the CP/M upgrade kit installed. Bent a socket pin on the CF card reader, destroyed solder pads removing it, and I don't even care because mistakes are learning opportunities. The ROM board from the upgrade needed a component lead(from a capacitor or resistor, didn't keep track of those trimmings separately) soldered to an IC I broke a pin on, the RAM board has a bodge wire because of another damaged solder pad and the TX/RX pins trimmed because I ended up with a short somewhere sending data through pins that shouldn't be connected... It's been an adventure for a newbie with electronics.
New CF card module is on the way, hopefully will get here tomorrow.
Amazing that the Z80 managed to be just good enough to stay in production for embedded applications for so many years after it faded as a general purpose CPU. We can have actually new parts for a system if not identical to, very similar to genuine retro systems. Emulators won't cover every situation, actual vintage hardware won't and is often too expensive, this is a nice option to have and isn't super hard to put together.
Excellent video David. Well done. Wayyyy too much soldering for me. Started in 78 - (all hobby) 8080 and Z80 S100 BUS systems using CP/M 2. Absolutely the best days of my life. Yep, I am a 60 yr old guy with a keen nostalgia for Z80 systems. Might have to look for a pre built Z80 CP/M solution. Keep up the great work! All the best, Edward
Fun build. I listened while soldering up a SMD practice board. Completely doable with a fine tip iron, fine solder, and a microscope (I got an AD407 to help with soldering) The hot air station was an effort saver, too.
It's good that this kit keeps all soldering as through hole. SMD just for one component would step up the difficulty significantly.
Looks like you got the full mid 1970s experience! Millions of solder joints and lots of fun trying to get everything to be connected properly and play nice together.
Obviously you would've gotten that terminal card working … but I very much recommend having a look at Putty's settings at some point and figuring out how to configure profiles to make this kind of tinkering a little easier. If for no other reason than to make your backspace work properly.
Thanks for this really enjoyed watching it ahead of my build starting tomorrow
I just happened across this video searching for "RC2014"; UA-cam says it was only 2 minutes old! And lucky too, this is a really good look at the RC2014. I'm interested to see what you do with it... :)
You were probably the first to see the video! The RC2014 is a great little device. Overall it is pretty easy to build, just LOTS of soldering to do. I only had a couple of issues, mostly a bad CF card.
@@codingwithculp UA-cam did actually say it had two views; I'm not sure who those would be though.
Great article, I had a ZX81 as my first computer, these were supplied with 1k ram, not 4k, but a 16k plug in memory pack could be fitted to the rear port and had a tendency to wobble and crash the computer, learnt some Z80 machine code on it as well.
I also had a ZX81 way back in the day, although I had it given to me after I had a C64 for awhile.
I actually have 3 ZX 81s in original boxes with 16K RAM expansion in my closet right now, they are awaiting a modification to the graphics subsection which allows them to be used on a modern LCD screen.
@@dwculp I moved onto a Sinclair Spectrum 16k next, though it developed a fault, and was replaced with a 48k version, because the 16k had ceased production, next I went onto a Sinclair QL, with the 68008 processor, after that, a Commodore Amiga 500, then built several PC's. Still have the Spectrum and the Amiga in a wardrobe along with 2 pc's that I haven't used for a while
Hey Mr. Culp, looks good with the programming. I am looking at getting into programming sometime in my college career

CP/M was created by a man by the name of Gary Kildall . Gary was also an avid private pilot (important to his story). CP/M had risen to prominence as an easy to use and powerful operating system that ran on a variety of platform , including early 8080 and 8086 based systems. IBM was developing the IBM PC and needed an operating system for it, they went to a man by the name of Bill Gates and asked if he could do it. But he didn't have a product in place at the time and he also didn't feel like Microsoft could handle it as they were still extremely small. But Bill Gates suggest that they go see Gary and lease his CP/M for use as the operating system for their new IBM PC.
IBM decided to do that and setup and appointment to meet with Gary at Digital Research Inc to discuss just this. On the day of the visit Gary was not in the office as expected, his wife was largely rude to the IBM people (IIRC) and Gary was out flying his plane. He was not fussed about showing up to the office, as perhaps the importance of this meeting escaped him. Anyway he took his time getting back to the office apparently and by then the big wigs from IBM had left. Needless to say they were decidedly not happy about the turn of events with Gary and Digital Research. Now either Bill Gates reached back out to IBM or IBM reached back out to him I don't remember, but Bill was not going to let this opportunity go a second time. That's how PC/DOS and MS-DOS was born.
It wasn't long after this Gary saw the IBM PC taking over the small market once used by CP/M and become a dominant force and edging out CP/M and forcing CP/M out of business after awhile. He remained in the public eye for awhile after this, and released products like Concurrent DOS for the IBM PC. But it's my understanding he never fully recovered from this loss personally (though I don't have any specific article to site right now). He eventually retired from co-hosting the Computer Chronicles on PBS and I don't think much was heard from him publicly thereafter. He was honored on his death in July 1994 by the Computer Chronicles. He was an early pioneer but remains an excellent example of being in the right place at the right time.
Although I didn’t do much with CP/M back in the late 70’s and 80’s, I did know what hit was and did a little with it. Gary was always one of my favorite people from the history of computing. I always enjoyed watching him on The Computer Chronicles. His untimely death was very unfortunate.
When you have an appointment with IBM, it's usually not trivial. What Kildall was thinking at that time would've been interesting to know.
Apparently this story is not accurate. Stewart Cheffet talked about this in his interview with Leo Laporte iirc
May I recommend using TeraTerm instead of putty. Not only does it do a better job at ANSI emulation and key translation, but it also has integrated file transfer protocols like Xmodem.
Excellent work and timing! I bought my RC2014 pro about 2 years ago and started soldering the back plane last night. :) I'm wondering how you connected your RC2014 to you computer. I too agree that this is an exciting and excellent project. Big thanks for sharing! Subcripted and waiting for your next video
You probably had figured it out by now, but anyway there is a dual serial sio/2 card included in the RC2014 pro kit. This card is connected to the computer using an FTDI USB-to-TTL serial adapter.
Очень крутая вещь, я уверен!
При чем, сам Z80, пусть и старенький, не исчерпал своих возможностей и в силах приносить пользу.
Интересно, в стандартный корпус с блоком питания ATX можно поставить?
Of course. The Z-80 microprocessor required only 5 volts DC.
ZX81 come with 1KByte of ram, not 4KByte.
by now, you must have noticed that you were missing the X after the NEXT in your demo BASIC prog
can't figure out what's wrong with my rc2014 cp/m setup, suppllied cf card didn't work, I bought a bunch of spares on local market and managed to run cp/m from one of those but looks like it works read only, can't write anything to card. sad (. ordered sd card card, hope it will work better.
These ridiculous backplane connectors were the worst decision I've ever seen. DIN 41612 connectors are a global backplane standard and cost the same as these toy SIL things.
Look at the hoops the designer made you jump through at 21:12, pulling pins out to make something fit? Sheesh...
And the PCB with the pointless cut out at the end, some kind of Apple case idea? Nobody puts these things in a case.
It's a shame that such a nice range of boards was kneecapped from the start, by some guy thinking he'd save 10 cents an a 100 dollar system :/
Nice channel though, subbed 👌
SIL = 10 for a dollar, where can you get DIN 41612 for a similar price ? This is a great little low cost hobby computer, great fun.
@@Paul-xs7ks DIN 41612 are around one dollar each. Now look at that as a percentage of system cost, it's nothing
Camera work is so bad ! Stop the close-ups !
