Has anyone successfully used non-DEC SCSI tape (cartridge) drives with
VMS? If so, what types have you been successful with? Travan? DAT? 8mm?
Which models?
I just hooked up an HP SureStore TR4, and it's recognized, the device is
an HP T4000s. But when I try to access it (INIT a tape, etc) I get a
"parity error". I don't have any Travan-4 tapes though, just Travan-5
tapes, so that's what I tried... Could that cause a parity error?

I've been successful with non-DEC DAT, 8mm, and DLT drives.

I just got a Seagate Python DDS-2 DAT drive, which works OK (well, VMS
handles it ok, but I've been getting a lot of drive errors... Think I
got sold a bill of goods on Ebay). I still haven't been able to get the
HP t4000s Travan-4 drive to work, although I know that drive is fine. I
think it's a hopeless cause. No big deal -- I'd rather have DAT anyway,
the tapes are much cheaper.

So as not to start what may be an OT thread, would anyone who
would care to answer a few questions regarding SGI IRIX, specifically
6.2, drop me a note offlist? Thanks.

New subject: Wirth's first DEC Pascal Compiler
Anyone have a copy of this DECtape ?
It's pictured here at the UVA computer museum
http://www.cs.virginia.edu/brochure/museum.html
More likely it was a compiler/pcode interpreter
for a PDP10or 11, but I could be wrong. Year: 1969-70
http://www.threedee.com/jcm/psystem/
The ucsd p-system museum has a DCD6400 tape they
can read with the source to a ver early Pascal system.
Since Pascal was first written for the CDC 6600, the
DECtape mentioned above was likely an early port.
They give this link to a Jensen Wirth interpreter- but it's dead
ftp://ftp.threedee.com/usr/syndesis/p2.zip
Finding the files pasint.pas and pascom.pas on a PDP10 tape
from ETH Zurich would be starting point.
I was able to find source for a pascal -s compiler

New subject: Wirth's first DEC Pascal Compiler
Heinz,
don't beat me if my memory plays tricks on me, but IIRC, I was using a
Pascal compiler on a PDP-10 in the 1980s, and this compiler had
something to do with the university of Texas and the university of
Hamburg.
If you consider this a serious hint, I might try to dig out some old
documentation and see if any particular names or institutions are
mentioned.
No tapes, however, this is for sure. Sorry.
Regards,
Andreas

I haven't gotten around to setting up a good, safe anonymous
ftp server since I became an ISP. I will e-mail that file to you.
Below are messages from Wirth on this subject. As far as I know,
he's got the tape but no 7-track CDC to attempt to read it.

Dear Mr. Foust,
I am sorry, but we don't have the source of the Pascal compiler any
longer. It was in use her until about 1980, at which time we switched to
Modula-2.
Sincerely, Niklaus Wirth

It appears that I found an old tape. However, nobody can read it,
because it is a 7-track tape, and 7-track units have died out! Bad luck.

New subject: Wirth's first DEC Pascal Compiler
I have a PASCAL-S for the PDP-8, which, incredibly,
given my limited knowledge, I managed to compile and
use to compile and run a few trivial PASCAL programs.
The error messages are in German. It is written in
PAL8 assembler.

I prefer DLT. Right now the DLT4000 drives can be bought off
eBay for $200-$250 if you watch. The tapes are a bit more
expensive, but I've found the long-term reliability of the
DLT tapes to be better than DAT.

I've used Exabyte 8200 and 8500 8mm drives and HP DAT drives under VMS
without issue. In the case of the 8200s it must be more than 10 years since
I first used one.

There were some patches necessary for earlier versions of VMS to use the
8200 without problems. Check the HPQ patch site for SCSI patches for your
version.
