If this is discussing a PDP-9 then yes, there is at least one in the
collection - the first Digital box purchased by La Trobe in about 1967.
There's an interesting story behind this system:
In about 1968 the -9 was stored in a basement area which was unfortunately
flooded when some high-pressure water pipes ruptured. My current boss (who
was Computer Centre Manager at the time) along with the technical officer
moved the -9 out onto a lawn and it was disassembled. The parts were then
washed and dried in front of radial heaters (one of which is still in use
in my bosses office!). The -9 was reassembled but three flip chip modules
were found spare! The system ran (without them) for about 10 years before
being replaced with a PDP-15, DECsystem-10 and Vaxes of various types. It
was decommissioned and moved to the DEA museum collection.

Yes, but we're nearly at the dawn of the 21st century. We've got like
what... 5 billion? And furthermore, there are several authors on the list,
who actually controll their temper.

So do you suppose it would be possible to take a shot at figuring
out how the thing works? I have no drivers for it. I could look up
what the 164P is wired to, saturday or monday. Do you think it would
be feasible to develop a driver for it?

I have a new copy of Windows 3.0 for sale. It's never been used but the
shrink is off of the outer box but the manual is still wrapped and the
disks untouched. It comes with 1.2m 5.25" fl;oppies but if someone wants
this and needs a set of 1.44m 3.5" disks I can make those and add them
to it.
I need $15 for it with only the 5.25" disks, mailed to anywhere in the
48 continental states. Add $2.50 (17.50 total) if you wish a set of
1.44m 3.5" disks included (copies from the 1.2's) to cover the floppies
and the little extra weight.
I have only the one copy so first come first served.
