I found a PDF of the workshop manual for the Casio FZ-1 sampler online,
and rescued it from what seems to be a rather slow and flaky site.
Why mention it here? Well, the FZ-1 (and indeed the FZ-10m I'm
repairing) are at least 10 years old and probably nearer 20, and are an
example of an 8086-based device that's a) not a PC, and b) is capable of
running user-supplied code.
Tony - you'd probably like the manual. It details what the various
ASICs do pin-by-pin, and even includes about two pages on how dynamic
RAM works and why it's such a good idea.
Even if you're not into weird old musical equipment, it's probably worth
a read.
