Hello everyone, I have an old keyboard that I want to use with a zx spectrum, however this keyboard uses an 8*7 keyboard matrix, and the spectrum uses a fairly unique 5*8 with some scan codes using multiple key presses (e.g. delete = symbol shift + 0).
Can anyone suggest the best way to translate the current matrix into the x spectrum matrix?
The only ideas I've come up with so far are too use an eprom which could be too slow, or to use a large microcontroller, but I'm completely in the dark about programming anything more complex than a bunch of for loops.
Any advice would be greatly appreciated, thanks, Mike.
