About 10 years ago, I too invested heavily in 44mb Syquest carts. The
reason I did, is because one of my clients at the time (a major graphics
arts firm (logos for the Olympics, Microslut, etc.)) was buying them the
way most high-tech companies buy diskettes: buy a couple of cases of them
and put them on the shelf for employees to come and grab a handful. And
they *used* them. All day long, and often all night too.
The syquests were also very popular with the Atari ST crowd too. Somewhere
around here (in *that* pile, I think) is an Atari branded cartridge.

At the risk of suggesting the obvious, have you contacted
the Heinz Nixdorf Museumforum? They have a web site at
http://www.hnf.de/ and one of the pages contains a list of
contact addresses. However, you will either need to read
German or have good luck with the translator at
http://www.altavista.digital.com/ (which is of limited use
on HNF's site because some of the text is embedded in images).

Only Reverse Polish Arithmetic! :-)

all 80286 ps2 models ran at 10mhz. wait states differed.

The installed chips are 10mhz but that does not mean it ran that fast.

They do come apart nice.
But everything is oddball compared to the rest of my systems (s100, CPM
and DEC based).

i might have something similar. i was given 5 shrinkwrap copies of ibm pc

i opened one to see what it's like and the rest are upopened. not much use

ps2 models arent really that hard to upgrade. the difficulty only comes when
someone attempts to upgrade it way beyond its capabilites. certain 95xx models
have used dx4/100 cpu also. eduquest systems are/were one piece mac-like
systems designed for school use. proprietary design, but so easy to work on.
some even had dos in rom.

there were certain 128k ram cards for the ][+ and similar but i dont think
programs could use the extra memory. early versions of appleworks could be
patched to use it and dos 3.3 could use the mem as a virtual disk. the pocket
rocket's memory cannot be upgraded.

Have you ever tried a HP 41? How does up to 961 external devices of
nearly every descrptions grab you? That's just one of the capabilities of
the HP-41 using the HP-IL interface. I currently have a 41 running a HP
logic analyzer!
(OK, I'll admit that HP tries pretty hard in this

They did a good job too :-)

The HP-41, 71, 75 and all the newer ones fit this description.

I'm new to the list and missed the original posting about the Friden delay
line. Can somebody forward to me the messages that have been crossed in
regards to the Friden calculator or tell me where can I search for old
postings?
Thanks!
