With reading this article Convergent/Unisys/Burroughs B25-K5 is not compatible with AT apparently.

Let me have some time to reseach Acorn keyboard protocol. I'll PM later.

  – looking forward to what you find. Thanks also for the information on the Unisys–too bad it's not AT compatible (although I was aware that might be a bit optimistic...)

Man, was that page on the Convergent/Unisys detailed, with schematics and all. Did not come up during any of my web searches earlier.
The guy also built a Convergent to PS2 keyboard converter, with the 8-pin SDL plug.

He also has the same/similar small form-factor keyboard as me used for testing. That one is extremely practical (although mine is USB)

Hi @hasu,

Just wondering if you had time to research this yet, and how feasible it would be to create firmware for the Acorn keyboards with the KART protocol. I can be of assistance wrt. sending a keyboard for this, if required.

Hi @hasu,

I am willing to purchase 2 of your USB to USB converters, in order to add programmability to a Ducky mecha mini and a Pok3r. Do you still sell those? How to proceed to order them (I live in France)?

Thanks!

Hi,
Yes, it is still available in stock.
Check the first post of this thread to place an order.

I'm wondering if the NEC 9800 converter would slightly work with NEC 8801 if the NEC is plugged in with a 5 pin to 8 pin mini din?

Hi,
Converter for PC-9801 does not work with PC-8801. The two keyboards are different in terms of their protocol and signals.
