Hi Group:
I have four TK50 tape drives available as surplus. All were working spares from a local DEC installation. I already have too many and have to get rid of these.
Here's the deal. A nominal amount (US$10 ea), and you pay shipping.
Please email me directly if you're interested in one or more.

I calculated the divisors in the program by hand, extrapolating from the values given in the technical reference for standard, higher baud rates.

They weren't that slow. We got some Beta units at the leg. for our Mac
platform. I used one as my *primary* drive for years. Was nice as I could
swap my development platters (MPW versions, other test junk) instantly. I
never lost data and they were very reliable... more reliable than the hard
drives at the time!
I am looking to buy one again now. I would like to back up all this dec
software on them. I know the data won't be lost if it goes on one of those
drives. I feel bad now because I chucked it in the garbage a couple of years
ago.... It had a carrying case and 12 platters :-(

IBM developed the front loading 2315 disc drive in the 60's, and is the
basis for Diablo 31, Wanco, Pertec, HP 7900, and DEC RK05 2.5Mb single
platter removable disc drives.
>Pertec Blue, I would suspect someone would want them for their Altair 8800b's
No, these aren't floppy drives.
I know.. take a look at the Pertec adds in Byte in the early 80's, and there
should be pictures of these drives in configurations with late MITS systems
after MITS was bought by Pertec.
Plessey also sold Pertec drives with their clone of the RK-11 disc controller.

Borland included TOUCH with their Turbo Pascal and Turbo C packages.
Also there was a version available thru PC Magazine, created circa 1988
by Michael J. Mefford. If your like most, you probably got some floppies
full of utilities that PCMag was always putting out.
Here is the syntax for the PCMag version:
TOUCH filespec [/D date] [/T time]
date = month-day-year
time = hour[:minutes[:seconds]]
Default is system date and time.

Good question. I'm not sure. The 37 has writable control store and
so when it boots from tape I think it will want to find a WCS image
in the SYSDUMP prefix on the tape. Would the 42 FOS tapes have that
WCS image?
I suspect there need to be at least two different types of MPE V/E FOS
tapes to boot all 3000s supporting MPE V/E: one for 37s (and maybe for
the various Micro 3000s -- do they use the same microinstructions and
WCS images?), one for 64?/68/70s, and maybe one for the non-WCS 3000s.

Hello, all:
Is there a DOS or Windows utility similar to the Unix TOUCH utility??

Thanks for the info Stan,
I sent an email to Allan asking about the upgrade and he was EXTREMELY
helpful. My system (HP 3000/42 Classic) did not have any patches applied
for a very long time so, he's gonna send the whole package. The best part
is it's absolutely FREE!
All in all, HP has been extremely helpful in providing upgrades for my 3000
and 9000s.

A friend of mine and I had about a dozen of those SMO-501's back in about
'89 or '90. We cleaned and upgraded them. Their performance on a PC of
that era was comparable to the previous generation of PC-based SCSI hard
disks. It was not impressive, but it wasn't terribly slow. We had so much
trouble keeping them at $1k each that I never used one myself at all. They
were just too valuable to keep. From what I remember, their performance was
more or less comparable to my Iomega 8" Bernoulli Boxes, though they were
MUCH larger in capacity.
