Can anybody point me to an actual photograph of the insides of a C-128 keyboard? Prefer .GIF format, but if all you have is a .PRG format, that will have to do.
I've already downloaded some schematics, which are pretty good, but I am facing the prospect of additional lines of I/O. And the keyboard scan, if I recall correctly, was performed sixty times a second? Since the prospect I am facing, requires about a million scans per second, there are many more lines of I/O than you usually get from $DC00 and $DC01. Basically you have to stabilize the 24 bit super-memory context and that's just to make sure nothing disappears from where it's supposed to be.
And was the C-128 keyboard patented? If it was, what year was it? What was its patent number?
