The Sinclair QL Forum

Found amongst some other stuff I am currently cleaning, its a keyboard interface I think, anyone know the company or what it actually does. I am particularly interested in the switches and what they do

Fascinating. Is that a processor and ROM? Where does it connect to the QL?

Hi,

that would be a "Keyboard-90" Falkenberg Keyboard Interface, originated from Juergen Falkenberg in Germany. Connects a PC/AT keyboard to the QL.

There's one on SellMyRetro here:

Juergen offered a number of QL hardware extensions in the 90ies

If it came with a manual, I'd be interested in getting hold of a copy to OCR as a replacement manual, I don't think this JFC keyboard interface manual is in my collection.

All,
just browsing through my waste-paper collection....

No, it's not a manual, I'm afraid, but an overview of products Jürgen Falkenberg was offering.
Hope you don't mind the German.

HArdware-wise this is a very interesting interface. In theory it could just as well manage emulation of any keyboard with an 8x8 key matrix. It uses a MPU to interpret the key-presses of an XT/AT keyboard and writes it into an 8x8 dual-port memory, made out of TTL chips. The memory implements an 8x8 crosspoint matrix that directly emulates the keyboard, so in essence it can emulate any combination of keys pressed, including all theoretical 64

Ta very much for the info guys, if anyone does have other useful bits of stuff about this interface, please post here.

I'll keep my eye out for the manual - I am sure I have one here somewhere

I've this piece of hardware. This time it's not used I have the german manual (6 sides) an could scan them on monday if necessary.

Oh Yes please, I could translate and add it to Dilwyn's Site
