Captain's case, microcomputers)], something like:
Limited - only a single run ever made, and then,
How about some of the rarer minicomputers that were made in the '60s?
Beasts like the LINC-8 (of which there were only 142 built) or Packard
Bell equipment from the very early sixties count here. PDP-1.
What about machines built at prototypes only (PERQ 2T4, PERQ3A, Tiger?
Tandy Deluxe Coco, etc). Some of those are very difficult to find.
Fairly easy to find.
DEC pdp11 gear fits, for the most part here, although a case can be
Processors, maybe, but some of the peripherals are a lot rarer. How many
people have heard of the DX11-B (IBM 360 or 370 channel interface for the
PDP11), let alone seen one or the schematics to it?
I hate to flog a horse that's weak, but there is more to computing
life than microprocessors. Whilst I don't disagree that the micro-
based machines should be preserved (they should), I hope that folks,
Absolutely. It never fails to amaze me that some 1980's home micros
(particularly Sinclar ZX80's, ZX81's, etc and Commodore 64's) still fetch
quite high prices second-hand, while I am often _given_ minicomputer
If you have the space to run one (and it's not that much, actually), then
a minicomputer is a very nice thing to have in a collection. You can learn
a lot about the operation of a digital computer by taking one of the
simpler minicomputers (I would not recomend starting with a PDP11/45, even
though I did!) and figuring out exactly how it works. You can watch the
control signals using almost any 'scope, particularly if you slow down the
clock a bit.
through their study of machines' history, become
aware of what is
now _distant_ history, even though it only happened 25-35 years ago.
Bitmapped displays and typewriter keyboards are nice, but it's also
The PERQ (sorry to keep on mentioning what I consider to be one of the
finest machines ever made) has a minicomputer-like CPU (260+ chips, 74S181
ALUs, 2910 sequencer, etc) that you can get amongst together with a hi-res
