In my experience great care is necessary with TK50 tapes.We bought a bunch
original DEC tapes recently, but it was necessary to clean heads before
reading every time.

Anyplace that sells older Intel chips certainly has them. Jameco,
in particular, has both the "regular" and CMOS versions, and with a choice
of speed grades:

I'd be shocked if you can't get them from Radio Shack.

p.s. I got at least one laying around but they're OOP
(out of production) I think I'll have to hang onto it.

Hey teen gang,
Does anyone have an Ultrix 4.4 (RISC) distribution CD-ROM they'd like
to part with, or make a copy of? I have a license but no media,
and I'd prefer not to try to deal with the Compaq Empire if I can
avoid it.
(P.S. - Plus, technically I'm kinda grey on whether the license I
have represents a "legitimate transfer of right to use" or not.
But since Ultrix is officially a deader-than-dead end-of-lifed
"These aren't the droids you're looking for; why don't you talk to
our nice Tru64 salespeople?" type of software, I don't really care :)
I just want to install the damn thing on a DECstation 5000/200)
(P.P.S. - Yes, I know NetBSD is better, and supports DECstations.
But I want Ultrix for reasons far beyond the understanding of
mortal men.)
(P.P.P.S ...Or women.)

Yes but . . . suppose a customer comes in with a software package which has
the "System Requirements" listed in the documentation. Customer takes the
system, finds out software won't run, even though the stated requirements are
met, and returns the system. We replace the system, and the software still
won't go. Then we discover that the software is buggy, or finicky. Does the
merchant still owe the customer a refund, even though there is no real fault
in the hardware? This happened to me, and it wasn't any fun . . .

A refund? Or replacement of the defective drive, under warranty??

Did Anderson-Jacobsen survive beyond the acoustic coupler days?
I have an old unit that could go up to 600 baud using Bell 103a
standards, although it was difficult to find anyone who would
support 600 baud using Bell 103a; 600 baud was usually Bell 202?
(whatever the standard was for 1200 baud).

Sellam is right on, here. If someone came into my store and wanted to
perform a component-level test on any equipment I had for sale, first I'd
assume they were joking, and laugh. If they persisted, I'd have to ask them
to leave. If someone gets zapped in my store I'd be liable. Additionally,
store personnel don't have the time to watch over such an operation to make
sure that the "tester" doesn't damage or steal something.
You might be able to get away with this at a hamfest, though.
