They're not Molex, they're AMP, and since they're the pins for that series
of connector they'll work fine. Both the connectors used for DEC PSUs and
20mA loop, and the connectors used for disk drive power, are (or "were" in
the case of the wide flat ones :-)) are from the AMP Commercial Mate-N-Lok
series. So are the 3-pin DEC power bus cables.

I should also mention that I believe them to be relatively new.
While there is no proof of this, they're supposed to come from
a company that went out of business perhaps two years ago, and
wasn't _in_ business for that long, AFAIK.

Clearly, your PC hasn't been smacked with an Etherkiller lately...

I recently received an Altair 8800 with an Altair disk drive
(Pertec FD514 innards).
In said machine is a Solid State Music 2/4k EPROM board with
2 proms: DBL and MBL. My understanding is that the DBL prom
is the boot loader for paper tape and cassette and the MBL
is the boot loader for the disk. Assuming the PROMS (1702s)
still hold data, I need to figure out the address of the
code. The board has two sets of four dip switches. One is
labeled T1 to T4 and the other A12 to A15. A jumper on the
board that allows settings between 2k and 4k is set to 4k
(1702s vs 1701s?)
Does anyone have a manual or a really good memory of how
these relate to the address of the on-board PROMS? I?m also
interested in finding out how the sockets are addressed.
The two proms are in the lower right sockets (the board has
2 rows of 9) and I?d have thought from the markings that the
upper left sockets were the first two to be addressed.
I?m not yet that familiar with S-100/Altair type systems,
but I assume if I know this address I can execute the code
to boot the machine (assuming the drive still works and the
disks aren?t bad. . . )
Thanks in advance for any help you can provide.

Beige. Are you saying that you can run OS/390 on an AS/400? That
sounds odd to me.

I know there are a few boatanchor fans here on the list, so I figured I'd
check here before spending yet another hour arguing with Google...
Basically, where are the good boatanchor related mailing lists and
resources at? I'm looking for resources on restoration and building home
brew tube based gear.
I have a National NC-2-40-CS receiver that I was given back around 1995 or
so, which needs its power transformer rebuilt/replaced, in addition to
lots of other minor repairs. Unfortunately, the former/original owner of
that receiver passed away before he could find the manuals for it that he
had filed away.
A couple of weeks ago, I was given an unfinished home brew 2 Meter
Receiver that is about 50-60% assembled. It was built by a friend of mine
who passed away about 2 years ago. Today, while cleaning out more old
parts and gear from his former shop, I found the faded plans for it and a
matching transmitter. Both appear to have been hand copied from the
October 1957 issue of QST.
I don't currently know when I'll have time to work on these projects, but
I'd like to have the resources and information I'll need available when I
find some free time.

For those that want on line manuals, check:
http://www.pdp8.net/index.shtml
Near the end of the page, under other you'll find
ASR 33 Teletype. Besides these he has a great site
for PDP-8's
I was thinking, it might be a good idea to make
a mold of the print head I have. One could then
make one in the future to replace it. I'm not sure,
not having it right here, but I think the head is
some kind of metal over plasic. It could be nickel
or something that doesn't rust. It could also be
low temperature type setters metal of some type.
