If this is a one off all you need to do is print the negatives on
transparency material with a laser printer.
The laser printers tend to have a little more opacity than ink jets do but
I have done this with an ink jet
printer as well. I also once plotted directly on the bare copper with a

The amount of data stored on 325 tapes would have been at most 58.5
gigabytes assuming 6250 encoding and single records over the length of the
tape. Given the time frame I would guess that these were probably only 800
bpi and thus the max would have been 7.5 gigabytes. And probably at most

Without looking at the schematics I can't tell you if they bothered to put
the resistor in there to make

Warren Stearns passed away early on Sunday August 6th. He suffered a heart
attack on Friday the 4th and never recovered from that. Warren was an avid

The whois record for pdp8.org lists its DNS servers as ns.spiritone.com and
ns2.spiritone.com.
What is interesting is that neither of those entries are in the
spiritone.com dns servers from my
point of view. However DNSStuff can get A records for those queries. This
means that they are

The circuit board material of the straight 8 front panel is fragile. The
resin
used melts at soldering temperatures. As a consequence my front panel
was munged up before I got it. Foils lifted kind of thing. I decided when

As stated this is a 128k word mos memory board for the 8/a processor. On
its own it would only present as a 32k board. To make it work as a 128k
you also need to have a M8416 board which drives the additional address
lines. And not all 8/a chassis had support for this. All 4 of my
