Yes, already saw that thread. But i don't got a eagle licence to view the schematics.....

Download the free copy of eagle, you don't need a full licence to view/edit a board of this size, thats what I did as I'm a KiCAD user too.

Whoops thx. I feel so stupid right now......

HI. I have a question, where can I found .hex file for PIC 16F627 ?

You can find the hex file for 16F628A here, but I think it should work on a '627 as well:

This may be flogging the deceased equine to some degree, but are these available for purchase anywhere? I'm in Aus if that helps redirect me to the right place.

Got a nice "new" A1200 without a case and this would help me towards my eventual goal.

I have acquired an A2000 with no keyboard, so I guess this could be a nice addon for that machine so it can be used with PC keyboards as well? I have some good old PC AT keyboards which are from the same time period so they wouldn't look too much out of place next to an A2000, and I guess this would work with both AT and PS/2 keyboards and it is just a different physical connector?

I have modded an AT keyboard (large DIN connector, i.e. not PS/2) for use with my A2000, using an ATtiny85. I even made a PCB with the proper connectors so the installation is completely reversible without soldering (finding the correct connectors was the hardest part of the project

). If there is interest, I could publish my code - it works for me (TM), but is pretty bare-bones (hard coded 102 key layout, no "online" configuration like the commercial adapters).

There was also a project on Aminet, using a PIC if I remember correctly.

Nice. I like ATtiny projects.
You should publish this. The large DIN connector still uses the PS/2 protocol right?

What are the 2 transistors for?

Other way around

But yeah, they are compatible. One can use a passive adapter to convert between the two.

No idea really, those are part of the keyboard's circuitry. I may put the code online over the weekend and post a link, or maybe make a new thread - don't want to hijack this one

I think I have a few ATTiny85 boards around here, so it would be very nice to try out your solution.

hmn · 30 June 2018, 16:08

I have put the code online here. I'm not actively working on this, and I don't even have my Amiga working atm

(so I cannot really test any changes), but feel free to PM me if you have any questions. I have attached a current build (IHEX format).

nogginthenog · 30 June 2018, 16:13

Nice one!

Thanks a lot !!! It works fine with my CD32
