I really want to do it in discrete logic. Call me crazy, enough
people
do as it is...
Sounds good to me...
Actually, I'd probably do it in 40xx CMOS, simply
because I don't
want
to have a +5V supply the size of a MIG welder lying
around.
:-)
What indeed... Now, Maplin do some nice 13mm LEDs,
how big do you
think
we could make a panel? How about the 3" LED
clusters they use as
tail
lights on buses round here? Make a PDP-8 6'
across, like the giant
MS-20 that Korg made for demo tours in the 1970s?
But then you'll need the MIG welder again :-)
