Hey, not the same machine I was referencing ;) The one Glen mentions
looked
pretty complete.
Looks like it was fairly well loaded with a complete
set of memory
cards and I/O cards.
I'd yank all those 64K cards and just run with one 256kw
board, keeping the
2nd 256kw board for spare. All those "little" 64k boards just suck up power
and don't give you much extra memory. I generally don't run things that
would require more than a pittance of ram anyways.... so others here will
certainly disagree with me on this point.
I just recognized the "unknown" board at the top in slot 25, it's a PSI
(Programmable Serial Interface) board (built on a 5180-1953). I think that's
a 3rd party board. I would like more info on these boards if anyone has it.
Sketchy info follows that may only be half-accurate: There are four Z80's?
on board as I recall, and 3 proms to dump your z80 code in to. Thus, you can
program this board to do all kinds of fun interesting things - IF you have
the specifications as to what your code needs to do in Z80 to talk to the
backplane or other chips on board. In the given configuration, it was used
to control 4 serial ports I think, but may have been just 2 terminals (the
ones I got were hooked up to a very odd very large graphics terminal that
required 2 serial ports each). I still have a couple of these boards, the
correct cables, and the back panel db25 mounting bracket. I have a manual
for them, but it is the manual for the PSI implementation of the board and
thus no details on coding your own Z80 stuff on it. If anyone has THOSE
specs I'd love a copy.
The other "unknown" board in slot 12, I have no clue, but I'd love to see a
picture of it, from the ebay picture of it what I can see is intriguing.
Warren... I'll gladly trade some of my HP boards in exchange for one or two
of the microcircuit boards in there ;)
I'm not sure if the FPP box will power up
completely without the power
in/out cable between the two boxes. I have never found a currently
available connector shell part that will exactly mate with those 9-pin
power supply connectors on the back. Maybe it doesn't matter if you
power the boxes up in the right order. It's been a while since I
bothered connecting the FPP box to my 2117F.
You know, that's a good question.
Can anyone answer that? Bob S. perhaps? My
hunch given past experience is that the power in/out cable isn't required. I
don't know though. I have looked for those 9 pin power supply connectors
too, to no avail :( I'd love to find some of the new crimp pins at least!!
AMP doesn't seem to remember making them. I would hazard a guess that the
FPP box would need to be powered up before the cpu ;)
