Three PS/2 to PCjr keyboard converters left.

Postby jmetal88 » Sun Jan 28, 2018 9:15 am

Hi all,

I have three PS/2 to PCjr keyboard converters left (my own design and construction) that I would like to sell. I am pricing these at $30 apiece, with $3 flat-rate bubble mailer shipping within the contiguous United States (if you are outside the contiguous 48 or want an upgrade to a cardboard box, I'll have to quote you). I posted a thread up in the For Sale section already, but it's not getting much attention so I thought I'd post here as well.

I will likely not make another batch of these unless there's a significant amount of interest, but as a reminder I have schematics and source code (aside from the PCB layouts) published here if anyone wants to make their own:

It's not a hard circuit to wire up, but if you want something that looks a little bit more professional, consider one of my pre-built units!

Thanks for considering!

Interesting.

I guess that the "62-key to 83-key translation code" (int 0x48) from BIOS is still being executed (unless you install your own handler).
So I wonder what is the key that maps to the "Fn" in a 102-key keyboard.... all those keyboard shortcuts should still be working on the 102-key keyboard.

I am translating the PS/2 scan codes to PCjr native scan codes in the software for this device. Since F11 and F12 don't have an equivalent on the PCjr, I chose to map F12 to Fn.

For anyone on the fence, I have one and I covet it, it works great. Many thanks for the project!
You're all insane and trying to steal my magic bag!

Alright, that's one unit gone, and one not gone but spoken for, so I guess that's one left!

And we're sold out! Thanks everyone!

I'll keep a waiting list for anyone else interested and start a new batch of I get at least five people on it. :)
