Can you bug the guy that has the 9820 docs? I still haven't found any.
I'm writing some articles about the 9800 calculators for the upcoming HP
confernce and I need to find out more about the 9805, 9810 and 9820.

It's clear from the above that you can't do a tape write, but it's not
clear where the problem is because a write involves both the read and
write channels. What happens when you try to read a known good tape?
If you know the problem is reading, it's straightforward to hook a
scope up to the read channel and trace the head signals through at
least to the formatter. If you know the problem is writing, you trace
through from the formatter to the write heads.

I was moving a cart full of HP I/O gear from system to system last night to
do some testing. On top of the cart was a DEC vt220 terminal. The keyboard
fell off, hit the ground and basically disintegrated!
Anyone have a spare vt220 keyboard or know where I might find one cheap?
Thanks!

RT-11 runs pretty nicely on a Pro. It's no longer officially supported,
but if you buy a RT-11 5.7 RX50 distribution from Mentec you will get a floppy
that boots on a Pro, and it is fully Y2K compliant.

If you'd rather have "straight block-by-block" RX50 images, look at
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/pro/
These are a bit easier to use (with PUTR) than the teledisk images.

It was an early printer, based on a typewriter mechanism (Olympus, I
believe). I used it with a Commodore 64 (this should help date it) soon
after the Commodore came out. The nine pin dot-matrix printers available
then gave poor print quality. The Daisy wheel printers gave typewriter
quality, albeit slowly, and had all the features such as subscript,
superscript, bolt, underline, etc. The Commodore printers of that era did
not have descenders for the lower case g, j, p, and y letters, for
instance.
I believe the price was $240.00
Cheers,
Lee
John,
Did I ever get payment to you for these?

Ask your friend if he'll be willing to hang on to it for a few
of weeks-- I'm in Kansas, and I could come a pick it up! (But
can't do it right away).
Thanks!

i havent played around with my NCR MCA machine yet, so i dont know the fun. i
know most of the 95xx IBM PS/2 machines had an IML partition accessed during
a warm boot by pressing ctrl-alt-insert. have you tried that to see if it
would work?
Hi all,
As promised, I have posted some pics of a recent retrieval of a Vax 6000
cluster at
