Yes I think that might be the answer. Do you have a spare that I could
buy?

For those who asked:
I have tried with no success to contact Bill Whitson to get another address to
send the 4mm tape with the Altair Scans (he must have closed his PO Box). The
tape is sitting in my office just waiting...

It wasn't until yesterday's topic of "Those pesky db15 ports" that I
remembered a couple of terminals that I hauled home recently.
The terminals have a DB15 for both the monitor and keyboard.
Anyway, I hauled home a couple of IBM 3101 terminals. They
consist of a base unit, a monitor, and a keyboard. From the ID
tags they appear to be around 1980 vintage.
I have not powered them up, but if anyone is interested in these
I could probably run a quick test on them.

DB15's are used by Mac II's (and related models) for video out. With an
adapter, they can use VGA monitors. Perhaps that is what you have?
Is there a separate port for a keyboard, or do you believe the DB15 also
handles the keyboard? (as in a real terminal)

I found out from a person in the area that low density DB15
ports if not used for Ethernet are used for a VGA terminal. Any idea
where to find one of these things? If you have one that you don't need
I wouldn't mind having it. By the way I'm still looking for a power
supply for an Amiga A500.
Any updates?

Don't worry, I didn't take it personally! It's just that all too
often, I can't promise much better for an artifact than that I'll look
at it, stick it in a folder and then in a file box in my storage
closet. I'm not real happy about that.

Yeah, I remember the RS/6000 episode, it was shortly after I subscribed to
the list.
I have to admit that I was thinking about those RS/6000s too. But what
I was thinking were the somewhat more mundane questions of how best to get
one out here to California, where I would put it once it got here, and
what I would do with it. See comment above about the storage closet;
I have way too much stuff there already.
Well, with a sufficient number I would be more inclined to put 'em in
use for their intended purpose -- moving IP datagrams around. But
there's probably newer hardware to do that sort of thing while not
needing as much space, cooling, and/or electricity.
OOB modems? Is OOB a brand name or an abbreviation for "out of band"?

Yep, and I really couldn't justify (to myself) being selfish about it.

Aiyeee, token things! Those also sound interesting, both because
they're RTs (another thing I'd like to dink with, someday) and because
of what they did.
Speaking of old Internet stuff...how many copies of the BBN report
1822 (on the host-IMP interface) do you think are floating around out
there? Wollongong (the mysterious office that I have alluded to in
other posts) had at least two and was preparing to toss both of them, I
think I steered one back toward the library and snagged the other for
my collection.
Back to SS-50:

I've found something else that sticks out in a crowd: I/O cards for the
HP 2100-family machines. (No, I haven't forgot about pulling those manuals
for you and Tony, just haven't cleared the space and time to really go
through them.) Today I picked up a TTY I/O MUXR card. The etched part number
is 12584-60136. No manual, but still in its bag. Date-codes on ICs seem
to be 7106, 7123, 7122, 7303. $0.50.

If you bothered to read a previous letter of mine help needed I'm
working on an old NCR machein that has thes DB15 ports that arn't
Ethernet and arn't serial but I found out from a very nolagibule person
was a port for a VGA terminal the other and most not often mentioned use
for them.
