Building an IDE68K then patching Kickstart 34.05 (1.3) to boot Workbench 1.3

[@thomaskockerbauer3965]

I've created that patch about 15 years ago. Nice to see that somebody actually uses it :) Sorry that you had so much trouble getting it working. I'm using it with an A500+ with an IDE68K board from that time, and scsi.device 43.45. Not sure why you needed that gayle initialization code. I have two theories but I'm not sure: - The CPLD code of the IDE68K might have evolved to be closer to the original gayle since the version that I got and might need that initialization now as well. - scsi.device 43.45 might do that already on its own. As mentioned in the html file I had to do a reset to boot from HD, but after that it booted every time. Somebody sent me a fix for that (also ready 10 years ago) so that it already boots on the initial power up, but I did not reupload the archive as we were not sure if it is a general solution (and its not my code either). That change had to do with the initialization order. I'll probably build a new IDE68K some time in the future, then I can check if the Kickstart I have still works with that. If I find the problem (thanks for the hints), and some time, I'll update the archive on Aminet. Btw, I'm already subscribed to your channel for some time, keep up those great videos!

[@CRG]

Thanks for all your hard work creating this. I was originally just going to change to 3.1 but after finding your archive on aminet I just had to try it. After it initially didn't work it must have take me a good few days of reading threads before I stumbled onto the EAB one, I'm just glad it got there in the end. I thought I had read somewhere that 43.45 didn't work with kickstart 1.3 although with only a 2GB card I don't really need it anyway. Good to know it can work though, should get you large HDD support. In terms of the code, I think the CPLD is emulating a gayle device and needs the code in kickstart to initialise, just my guess though. Certainly without it there is no sign of life. If you do build another IDE68K and decide to update the archive please let me know and I'll update the links etc in the description. and Thanks for subscribing, I truly appreciate the support.

[@a500]

Great work. I’m glad you succeeded where I failed. I must have spent far too much time trying to get a 1.3 kickstart to boot with IDE.

[@CRG]

I was so close to giving up and just using 3.1 but it was reading the full eab post put me onto trying scsi.device.40.5. I was genuinely surprised when it booted 😁

[@AlistairBrugsch]

An easy way to desolder 40 pin header blocks is to place a length of heavy copper wire conductor (like the guage in a mains earth wire) place it between the pins, and run a large bead if solder down it. Then with an iron on quite high or hot air you can run the heat up and down, and the cooper will keep the whole length hot. Then the connector will just drop out on its own and the remaining solder mess is easy to clean up 👍

[@CRG]

Great tip, thanks.

[@user-wj9xq7ig2v]

I think I will test this with a cartridge slot on a junk snes board. Great tip

[@chadsarcade6007]

Great video! I took the same journey a year or so back, only I had the additional obstacle of having used PFS. What I didn't know at the time was that the version of PFS I had chosen didn't work on the KS1.3 / A500 combination. Even when I finally did get the right combination of scsi and initialisation patches and had a working ROM, the machine would boot to a guru error. I interpreted this as "still doesn't work", if I'd though about it I'd have realised it must have been executing code (from the HDD) which it didn't like. Eventually I emailed Thomas who was very helpful, and when I realised I did have a working ROM I stripped it back to FFS and I was in business. (I did find a working version of PFS, I'd just grabbed the wrong version from and old floppy).

[@darkstatehk]

I really enjoyed this, very useful and informative.

[@rabbaga5t]

Another amazing video! Thank you! I already have the parts on the way in the mail to build one myself so your video is perfectly timed :) I was able to find the missing voltage regulator on aliexpress. Have you considered a digital microscope for the soldering? I initially found it hard to use because you don't get stereo vision, but I did get comfortable with it after a few nights of work using it. They are not too expensive from Banggood etc. I got an ADSM302 for around 100 GBP on special, delivered and features HDMI out which would give you footage for your videos. Keep it up :)

[@CRG]

Thanks, good luck with your build. A digital microscope is probably what I need to be honest. Thanks for the tip, I'll take a look one. HDMI would be handy for video footage as you say.

[@timstevens8245]

Love your videos man. I want to do this to my 500 some day. Love your persistence 😊

[@decidedly_retro]

I find the 1.5x magnification on those head magnifiers the best/most I will use. Anything more gives me headaches and has too short a depth of field. However, with that 1.5x set of lenses it's far better than the other magnifier.

[@CRG]

I'll try that and see how I get on. Very tempted to send it back though.

[@EgonOlsen71]

That's exactly, what I experienced too. I couldn't stand anything higher than 1.5x in the beginning. But after getting used to them, I can now use 2x or even 2.5x without any problems. I don't want to miss it anymore.

[@Charleshawn66]

GREAT VIDEO!!!! Just amazing how you can do the super tiny surface parts!!!! I have a soldering setup and a nice kotto fume extractor with the 2 foot flex hose inlet. I'm brand new to soldering and bought all the stuff in the last 6 to 8 months. I bought it to be able to change the power switch in a Commodore 1084 monitor and that was easy! (4 big wires). I have bought some learning kits off of Amazon and I'm getting better at through things like sockets, resistors and capacitors. I have a NeoRAM kit (GoeRAM clone) for the C64 that I want to build. 90% is through stuff that I feel I can do, but then you add one to four 512K RAM surface mount chips giving it 512K to 2MB. Not sure about those surface mount chips and don't want to ruin it? I'm 56 next month and I wish my school had had electronics classes when I was in school 40 years ago!!! I should be happy that they got their first computers (17 - TRS80 model 3's) in my 11th grade year. Those did teach me PASCAL in that class and I taught the teacher many things in the Basic class because I had self-taught myself Basic in 1982 when I bought a Timex Sinclair for $99 from saved mowing money.

[@CRG]

Thanks, surface mount soldering does take a bit of practise but honestly I now find it easier than the through hole stuff, certainly a lot quicker. The best advice I can give you is to get good flux and leaded solder. When I built the first rgb2hdmi board I was using a cheap flux and it made life so much more difficult but with the good stuff the solder just flows to were it needs to be. Take your time to align the chips, use something to hold them (I used the tape as you seen), plenty of flux then just go in with the solder. If a part is miss aligned don't panic just use hot air and the tension of the solder should pull it into place, or you can give it a nudge with your tweezers. The biggest thing to take away from my videos is that if I can do it then anyone can. I don't have any training in electronics, everything I've learnt is just from watching other videos and diving in. Yes I've made a few horrendous messes but it's part of the learning curve, part of the fun. Good luck with your build and please if you can let me know how it goes.

[@Charleshawn66]

@@CRG Thank you for the encouragement! I will. You wrote "get good flux and leaded solder" could you tell me what you use for both of these and where you ordered them from? I also do have a handheld hot air tool with 2 or 3 tips that came in a kit box with 500 different size shrink tubes do you think that gets hot enough or does it need to be a hot air tool made for soldering work? If so, what hot air tool do you use?

[@LeftoverBeefcake]

This is a pretty cool project, glad to see it all worked in the end. It would be fun to get my CDTV to boot from a hard drive with KS 1.3 and have 8 megs of RAM, but I don't think that stack of boards will even fit with the top lid closed. :(

[@CRG]

I'm not familiar with the insides of the CDTV, would love one but they are fetching silly money these days. Maybe a CPU relocator would help? Also bear in mind you could build the fast ram board directly on top of the ide board to make the overall tower a bit smaller.

[@ncot_tech]

I’m an ST owner and even I found this interesting to watch. Just how many things can you stick in that poor 68000’s socket 😁 It’s good seeing that things are difficult and don’t always work straight away, and also that I’m not the only one who finds the answers to problems buried in forum posts from 20 years ago.

[@CRG]

Things rarely work first time, especially in my hands :) Thankfully we still have the old forum posts as a resource. I'd have been lost without it.

[@simontay4851]

Its not good, its frustrating. Why couldn't there have just been a single rom image that you can just download and program the chip with. Im sure you aren't the only person that had problems getting it working. Please upload the ROM image that you programmed the chip with that eventually worked.

[@CRG]

I can't, these ROMs are still legally owned for distribution by cloanto. The only way to obtain them is to buy Amiga Forever. That pack of course doesn't contain this modified kickstart as it was never available originally. In short while it's frustrating the only way to obtain a modified 1.3 is to do it yourself.

[@helmutzollner5496]

Amazing! A real Wow Job you have done there. Great to see your efforts to keep the old darling up to date enough to allow the integration of reasonably modern PC hardware to ensure the continued availability if a HW platform for the Amiga software. In the late 1980s I was an Atari ST fanboy and built a similar CPU tower with a 68030 and an 8086 co-processor and extra RAM. I foundvthst the socket towers are always less reliable. Recently i saw a youtube flic, where a creator built a brand new Amiga 500+. Apparently the circuit diagrams and the PCB layout are on github. Would it not be time to respin an A500+ PCB to include ALL the mods you have given your A500 if this series? If you use Laptop memory bars or modern RAM chips, you can make room for a lot if additional circuitry in the old RAM bank area. AFAIK all the Amiga custom chips are now available as FPGAs. Purists could even harvest the custom chips from old A500 boards. I guess the RASPI RGB to HDMI mod could/does also supply LAN/WLAB functionality. Is there AmigaOS support for TCP/IP or networking in general? Just a thought.

[@bamdadkhan]

28:07 - i'm no expert but wouldn't it have made sense to increase the buffers a bit if you have plenty of RAM?

[@mkl-68k]

If your CF adapter has a diode between IDE pin 20 and CF power supply pins, it will reduce the voltage about 0.3 volts. Some CF cards might not work then. With 3.3 volt CPLD on IDE68K, the CF voltage should be the same and not 5 volts, or some CF cards may not work, because they need IO input voltage of 4 volts minimum as they are CMOS level inputs in the CF specification. (Moreover, at 3.3 volt CF power supply input, the specification does not allow the I/O voltages go much above 3.3 volts)

Is it possible to change the chip memory range from 2MB to 4MB or 8Mb/16Mb/32Mb/64MB/128Mb/256MB/512Mb or more? Is it possible to replace this memory in the Amiga with a larger and faster one?

[@CRG]

Chip ram is limited to 2MB on all Amigas apart from emulation. You can have up to 8MB of Z2 fast ram and I'm not sure what the limit is on Z3 but over 128mb is honestly pointless. For day to day Amiga use even much over 16 or 32mb won't be used, not unless your doing a lot of art or music production with a load of samples.
