I've been attempting to diagnose the problem of an old 1980s broken keyboard. Its one I've had for years and has never worked. I really want to get this working. It would look good with my 486 PC. I've checked all the simple things first with a multi meter such as the lead and other connections and all is good so the fault is clearly one of the 7 chips, either that or it was made to work on only one type of computer more likely to be one of the chips.
Its a FERRANTI keyboard which has the following numbers FT09
PC1 002631
55-02823-197 251-B
On the PCB it says A65002823-174 PCB 251B
If anybody knows anything at all about this keyboard any info would be helpful. The PCB has a year of 1979. I might have to ebay it for parts otherwise.
