- E259: This is the new TF1230 from SJL (Stephen Leary ) for the Amiga 1200 it provides a 60830 at 50mhz and 64MB 32bit fast ram! all for under 200$ usd in this episode I install it, figure it out, then wonder why it does not show up in auto config, or boot from its ide connector. you CAN boot from a custom rom. However i did not know this in this episode. i acquire the ehide.device and get it to work. oh i also break my keyboard ribbon i just purchased....

I need to add a important comment abot the FPU:
It is not added as that would impact ramspeed due to design. and the goal with the TF1230 is one thing and one thing only: to make a cheap affordable 030 card for the Amiga 1200 based with the designidea: KISS (Keep It Simple, Stupid)
this is why it have only the CPU. and to be honest on a 030. fpu is "useless" it doesn't add that much speed on software that is fpubased and if you run this kind of software. 030 is not really the platform for you. then it would be 040 or 060 as there you have a extremly much higher "umph".
sure if you have a 030 accelerator with a fpu socket, then I usually added it as "why not" but take the ACA 030 cards even if it does support fpu. it is not supported by the designer and will actually make the 030 slower due to impact of ramcontroller. (also invalidate your warranty)
on the TF it simply was not added as it would add routing AND also more support needed for firmware etc. mighteven added a slight more cost.
not even the IDE would be there. but as it is the exact same design as the TF1260 it is just a "copy+paste" anyway.
why no autoboot etc? legit question I would say. answer is: KISS. adding a rom with the driver would add more cost.. and that would break the idea with the 1230. So choises was: keep the ide as it is. or just completly remove it.
there would be another solution to make it autoboot: make it replace the internal IDE. BUT. as the internal ide and pcmcia shares registers this would also disable the PCMCIA controller.. so not an option either.
this is why it is like this. however I would not call it a kludge or a hack. it is just a form of RTFM. even if this builder did not send any information ,it is just a googlestep away..
I did and got it sorted in p2
Thanks for the video Chris. Just received my own TF1230 this morning, so the timing of this was perfect. Need to try mine out this evening and see if I can get it all working or not. Also running OS3.2
Stay tuned for part2 where i rig up the hdd boots without a custom rom
Very excellent work for awesome kit and far far intelligent including Amiga 1200✔
Cool video. The FPU is vital for many things and is not useless. However, open source accelerator cards are great and that is especially for the reason that they contribute knowledge. An FPU can be added to (other) accelerator boards in an affordable way although it takes extra work because they can be mimicked via FPGA (basically making a clone of the instructions). In fact, not only this but an FPU can be made which is far faster than 50MHz. You can put a 100MHz FPU (although there is some inefficiency) on a 50MHz CPU.
FPU is used for plenty things such as 3D software or games (including homebrew) which use Z-Buffer rather than integer based arithmetic _(which is what the old Doom did, althouh newer such games have be written to use FPU and faster CPU)._ BSD can be run on an amiga to play linux games that use FPU. An FPU is also for transcendental operations and especially Fourier Analysis such as playback of some media types. New media playback ability is added to the amiga all the time these days. Some Public Domain software sometimes uses it too. Compression also uses it, as can hashing (be it polynomial based or otherwise).
Before anybody pulls rank, I have a First Class Honours degree in Computer Science. That however does not _"make me correct"._ A person can be correct whether they have the qualifications or not. What my qualification does do here in this instance though is disprove an appeal to authority in case anybody else here tries to say, on account of them having a computing qualification, that there qualification makes them "correct" if they say the FPU is useful or useless.
With all due respect, some things are not a matter of opinion. There is such as thing as "the truth" in computer science.
Again, I wish to reiterate that I am glad this great little accelerator board exists (especially for the Open source history behind such projects). I think the work put into that accelerator is commendable because of the open source background to such boards.
There are plenty other accelerator boards, and some are open source. Those can be tried too.
Be mindful also that, for people who wish to use FPU software, it is possible to add a fast FPU (even faster than 28MHz) to the standard A1200 without using an accelerator and that is because you can overlcock the 68020 CPU to 28MHz so that it will perform about the same as a 25MHz 68030 although you would desire fastRAM (which of course can be added in more than one way), and therefore the FPU chips can be added to your A1200 Amigas by pull-up resistors and caps, directly in the motherboard.
A 28MHz 68020 (performing like a 25MHz 68030) when coupled with a very fast FPU _(or mimicked FPU such as FPGA just for the FPU, not the entire CPU)_ can outperform a 68030 50MHz in some FPU punishing tasks. This is also worth noting when looking at the CD32 because you can do pretty much the same thing with that but also it has an akiko chip which is a gate-array that does chunky2planar conversion faster than a 25MHz 68030. As such, the FPU on the CPU can be used for other things such media and ZBuffer and compression simultaneously in future homebrew games or rewrites of old games.
The instruction-set is a big part of the ieee benefit to a 68030 because it added decent serial. However, the 68040 added decent parallel by ieee1284 too.
Trying to perform FPU operations on a CPU without an FPU present is often punishing to performance.
I think that’s the longest comment I have ever had on any video ever
@@ChrisEdwardsRestoration Well I liked the video. Mind you, as for my wordcount _(which requires long words and jargon hence a higher character length),_ I can see back-and-forth commenting by other people on this comments-section and their wordcounts in a thread exceed mine, because they have broken a longer wordcount into multiple comments instead.
My strategy, however, was to keep my comment as one comment.
There are a lot of words spoken in various amiga (and retro computing videos) in the video's audio (on various channels) and so addressing the topic in text requires long wordcounts sometimes so as to give the topic a fair covering akin to the video.
It is a commonplace thing people say that they perceive comments to be a long wordcount compared to a spoken-word version even if they are the same wordcount. It is a perception thing.
Again thanks for sharing your experiences in your video. It was nice to see the show-and-tell of the amiga.
Another awesome vid Chris 👍🏻 This time I learnt I’ll be using my Phase 5 mkIV 68030 with SCSI for now for my 030 needs or my blizzard 68060 with SCSI mkiv setups😂👍🏻. Have got my hands on a Vampire 1200 V2 card which also has a IDE port built in. I read that Chucky and the team will only be allowing free firmware upgrades to those who bought their TF cards directly so to stop people buying these and the TF1260 and flipping them on ebooger 👍🏻 Have seen a couple listed as of late.
I'm very interested in one of these cards now! Looking forward to part 2!
I'd assume that you'd want to run a better PSU than a stock one to make sure it has enough power for the accellerator board.
Does this board need the timing fixes doing on the mainboard? I have a rev 1D.4 system.
I have a newer ps but it works fine on the original as im not spinning a rotational hdd
I have the 128mb version and it’s a great card for the price. Like you though I found it an absolute bastard to fit and had to dismantle my A1200 to get it in. I like to call it the terriblefit 😝. Seriously though I can’t really complain as it’s the fastest card at this price point and much faster than my ACA1221.
Thanks for the vid guess I will wait for icedrake, buffee or piestorm need more then 40/50mhz
You will never stopped surprised me mr .Chris . :) like always, master of hardcore ;) like ! :)
No idea what’s what. As I didn’t have an Amiga. But enjoy watching the tinkering and the jokes contained therein. Keep it up!
Thanks for making the video. I have ordered an 64 mb version as well. Waiting for it to arive.
hi chris, just received mines this morning, cant get it to boot at all if using a long cable from internal ide to the back right amiga port, even some short cables out my collection didnt work, also had dead card until i tried a kinda hard push on the cpu socket, now works fine., Question if you know the answer tho, how do you get HDToolbox to see a second cf connected to the TF's ide port as my hd toolbox finds nada ?
in the part 2 description i have the driver files linked. ua-cam.com/video/JrehlQliGY0/v-deo.html
@@ChrisEdwardsRestoration ok, just watched it, thats what i tried, it took ages to go through its search and then found nada
@@martinclark1411 its right in the extended description...
Hi Chris,
I own today a tf1230 too buuut, igame refuses to open with 8000000B error. Is something about FPU? I test with 68k exe igame, 030... and other libraries in MUI with no FPU required requirements, but nothing...
With my 8mg expansions works good (with FPU).
Any clue?
Thanks Chris.
boot without caches
You state the DELL U2410F supports 15khz horizontal scan? All the documentation I can find for it refer to the U2410 which does not support 15khz. Are you sure it supports 15khz without any kind of doubler? I've been looking for monitors that support 15khz for a while and there aren't many around...
U2410-F I Have used it for the past 3 years, and yes it does 15khz just fine. its 15-95khz refresh rates i just did a search on ebay and found a ton, most under 100
@@ChrisEdwardsRestoration Thanks for confirming! Buying 2 of em now! LOL!
just tried an msata to ide adapter, And although my tf sees a cf card without issue it cant see the msata, just out of interest hopefully to folks on here
Because amiga is pio mode 0 or 1. Your new device needs to talk old school for it to work proper
@@ChrisEdwardsRestoration the amiga ide sees the cf card and also the msata without issue, its the ehide device that cant see the msata!
I see
@@martinclark1411 The ehide.device/IDE port was a tick box in that the IDE was added to be very basic and works well with CF and some DOM's.
Ho-ho-ho!

So I noticed that you could chose between NTSC and PAL. Is this the case with all A1200's so you don't need to worry about getting a PAL or NTSC version?
Hello. I have an Amiga 1200 with a TF 1230 but it gives red screen. Is it a proplem with the CPU on the card then?
red means rom error
@@ChrisEdwardsRestoration ok. The 1200 work without the Terrible Fire. 🤔 Is it the kickstart rom you mean?
Are you map rom? Try reseating the connector and leave it hang out 2 mm or so
@@ChrisEdwardsRestoration the 1200 is not setup at the moment. I will try when its set up again later. 😁
@@ChrisEdwardsRestoration I think i bought wrong version of kickstart 3.2.1 without opdate for TF1230. Does it have anything to do with this problem? When i got the bord it was litle bit unstable when i start the 1200 or boot it up. I have an old 4 meg bord how works but its to small for WHD load. 😊
Awesome. You are my hero. So, how are you going to add a FPU next? Must be someway.
something weird like a clockport hack?
hello there you need new roms for it that is why is it not booting from the ide on the TF1230 when you get the roms it will boot from the TF ok
Yes i am aware. This was stated in the video desc of both parts. thanks!
Thank you for another great video
Some websites saying these have issues on 1d1 revision boards and other sites say fully compatible with all revisions, does anyone know for sure which is correct as i fancy one of these but my 1200 is a 1d1 revision
there was 2 1D1 boards that had issues: it later was found BOTH those A1200 boards had hardwareissues.. so it wasn't the TF fault
@@ChuckyGang so a 1d1 board should be fully compatible then ? Provided its not actually faulty
@@martindianeclark7841 yeah
I've just received my 128MB TF1230, and have it working on my 1D1 board, with the only issue being that I was using a Long IDE cable to my CF card, and it wouldn't boot, but changing to a short cable or direct adapter worked without issue. (Totally unrelated to the 1D1 board anyway )
@@42markk42 that is due to no buffered IDE.. same as the internal one
