Good - if you can find some RCA file numbers for the 1801's in there
for Eric, this'll be a huge step forward in getting the 1801 data sheets
from RCA and/or Harris.

Yep - this is why you need the file number before you can get any further.
The data probably exist in paper form, but aren't indexed in any of the
on-line databases that the manufacturers still have. It's like getting
obsolete parts from DEC; first you have to convince yourself that such a
part still exists, then you have to find the part number, and then you
often find it's an off-the-shelf item even though it might not have been
produced for 20 years. (Examples of stuff I've ordered in the past few years
are RX02 and RL02 drive belts, and even a can of Magna-See.)
In the case of DEC parts, having a dumpster-dived copy of the "Option/Module
Hardware List" stamped "DEC Confidential" all over it helps a little
bit :-).
