Jerome Fine replies:

Thank you for the advance notice. I doubt I would want to pay
for the shipping, but if the local company or you were close enough,
this might be interesting. Can you please specify where the local
company or you (or both) are located - which city? I am in
Toronto and anything more than a day (even a very long day)
of round trip is likely not worthwhile.

My suggestion - even if I am not involved - is to save all the board
modules that you can and leave the power supplies and the backplane
to the end. In the middle might come hard disk drives (up to 5 1/4")
followed by removable packs that might contain any software of interest.
Interface kits for serial lines (DLV11-J, DZV11 and DHV11) would
also be useful and are relatively small. For very small systems, the
DSD-880 boxes are very useful. Most have an 8" floppy beside
the 8" hard drive which is 3 * RL02 (non removable of course)
and also restricted (from what I remember) for use in a 1/4 MByte
memory system unless you are running TSX-PLUS or have a
modified RT-11 driver. The used of a DSD 880 in a VT103 was
very useful in that there was only 1 dual module for both the
hard drive and the floppy which also contained a BOOT ROM.
Combine that controller with a dual 11/23, a DLV11-J (4 serial
ports), and 1/4 MByte of memory and you had a minimum
system. For very little more money (today - not back then),
you can substitute an 11/73, 4 MBytes of memory and add
a DHV11 for 8 more serial ports. Of course, you would have to
rewire the backplane to allow the extra 4 address lines.

Allison, would you have any interest in this stuff. Also, Megan!

ALSO: TO ANY ONE WHO HAS A PDP-8?
A business friend of mine had a requirement for a model
with a 50 Hertz power supply for an overseas site. Anyone??

Sincerely yours,
