I have seen only one in my time, and they are quite rare and I cannot
remember who made them. They used an interface that plugged into the
8049 socket I believe. You certainly cannot fit a std QL keyboard to it.
If you cannot find one of these then you have the following choices:
1) Refit the QL keyboard. You would probably need a QL membrane. The
8049 is probably fitted to the internal added pcb.
2) Find a second hand IBM keyboard interface (Di-ren, Falkenberg or
superHermes (and Lite)
3) Purchase superHermes or superHermes Lite from me.
4) Send your media (microdrives I assume) to someone like me for recovery.
I assume you are simply wanting to recover data. This could be copied
to floppy disk(s) and you could use a PC emulator to read and recover
them. The Psion programs will run quite happily from floppy disk under
an emulator.
BTW if you recover your QL keyboard, a must is the pointer environment.
Part of that is a quick mdv copy extension of the format command -
assuming, of course, that your files are on microdrive.
