i could probably scrape up an LSI-11/03 CPU and a 32K ram card for you, but
you'd need to dig up some of the other parts.  and you would have to be serious
about doing it.  or at least serious about getting it running and getting an
OS on it.

i've always liked them, but the one big downfall with them is they require a
VERY large amount of memory compared to anything else.  but that's the price
you pay when you make some choices.

by using it.  if you do it all the time you will remember.  if you don't do it
all the time you won't remember.  doesn't matter if there are 20 instructions
or 2000 instructions.  maybe, i could be completely full of shit.

it would require copious amounts of research to use, so you really think about
your problem.  hmmmm, that has merit.
