ISA card of course. There is no point at all in putting intelligent MPU on a PC with ATX slots.

Ah, wasn't exactly familiar with those ... are they easy to source? If so might be worth considering.

So, I did look on eBay for this solution since a ready-made cable is nice.
The cheapest ps2->at keyboard adapter with sufficient quantity costs 1.75GBP. The adapter alone is already more expensive than the DB9 bracket.
I couldn't find these "atx brackets" on ebay, I don't imagine they are 1GBP either...

Guys I don't see such a change coming... I already have the local guy (same one that arranged the pal cracking) fixing and finalizing the pcb design and his fee was a "friendly one". He is also arranging the pcb manufacturing when/if it comes. If I go and bug him to make trivial changes then this friendly service is at risk LOL

btw , here is what the hand-made adapter will look like:

it's not that bad and the current design works without any modifications with cheap serial brackets :)

I'd buy one of these. Bonus points if it's in kit form.

Capital controls and the current economic situation in Greece put a halt on the project sadly... I'll update when things get rolling again , in the meantime the whole endeavor is in sleep mode LOL

In the mean time, I'd love to get any files you have related to this project, if you're willing to share. I can probably get some PCBs ordered and build a prototype or three.

Do not destroy those ATX form factor cards if we are not talking about new ones.

If you have for example a PC-Chips M577 or a similar Baby AT Super Socket 7 board its a pain to find the correct ATX form factor card for it. I bought a second M577 from Italy :D just to get the form factor card.
Main PC: Dual Xeon X5690@4.6ghz, Evga - SR-2, 48gb memory, Intel X25-M g2 SSD and a Nvidia GTX 980 ti.
Retro PC #3: K6-2 450@500mhz, PC-Chips m577, 256mb sdram, AWE64 and a Voodoo Banshee.

Can't you just adapt regular PS/2 and USB brackets to work on the motherboard, though?

Ok, I'm impressed. I don't think I've seen a project go from idea to finished product so quickly. Well done!

PM me if you want to me do a video review on it. Always looking for new projects.

I think keropi has been working on that one for a while now. There was a different thread regarding that one. (a clone of the MusicQuest clone)
