It's weird, that... I suspect I could rustle up something 'traditional' around
a Z80/6502, ROM, RAM and some decoding - but my brain just doesn't cope well
with single-chip 'black boxes' such as PIC-based widgets. I really don't know
why!

I cna think of one good reason why _I'd_ bother :
I prefer to think in terms of AND gates, flip-flops and shift registers
to assembly language. I find it easier to debug a board of logic than a
program. And I'd findit simpy more fun to sodler and wire-wrap than to type. I've had idle thoughts from time to time
about building one of those and
sticking an EPROM between the outputs of that circuit and the device to be
driven, to convert the scan codes that you get to ASCII or whatever. Maybe
one of these days I'll get that particular round tuit. :-)
Why bother? AVRs
and PICs are cheap and easy to work with (in
