I have 30 small (6" dia) VAX tapes (Opus 6250) and 12 large (7" dia) VAX tapes (Scotch 700).
I believe the small tapes are 600' x 1/2" and the large tapes are 700' x 1/2".
I think they have all been written on once with data - no executible files.
Tapes are free if you can pick them up in the Northend of Seattle.

Nope, he scrapped it the next day. It's on it's way to China now. :-(
Art has some fiber drives but I don't know if he'll part with them. I'll
probably see him today. If I do I'll ask. Sorry I haven't answered your
messages soooner. We went and picked up three more loads yesterday and I
didn't get back till late. I'll try to pack the CD drive and get it in the
mail today.
BTW we got a SGI Onyx Reality Engine2 yesterday. It's HUGE!!!!! I'm
taking Bob R. out to look at it this morning.

The DEC MINC (a PDP-11 dressed up for Laboratory use) typically came with
an IBV11 card - Qbus GPIB. I have one but I've never programmed anything
for it. Presumably, the MINC manuals have more than enough info to get
a working start under RT-11.

I was told, but cannot verify, that one of our local
newspapers (the Louisville Courier-Journal) had one
of these systems; the guy who gave me a "printout"

various fonts with various additional attributes
like boldface, Italics, etc, printed on a plastic

a DECsystem-20.

Therein lies the difference, the use of CRC vs ECC, floppies have a
fairly
high soft error rate compared to hard errors so detecting an error and
rereading is the strategy. It is also an economy of design that comes

Some months ago I asked on this group what the Computype Compuedit computer
was. I was told by someone (who is that person, by the way?) that it was the
front-end machine to a photo-typesetter from the early 80's. Does anybody
know where I can find pictures of this thing in operation?

No Your not! it is a lousy oscillator and susceptable to stray and all
manner
of bad things. I've seen them NOT work on very well laid out 4 layer
boards
as well.

Yes it is, I've used it to 1GHZ with great success. While I was sick
last week
I even kluged a 75m phone RX on a 2x4" peice complete with 6kc bandwidth
mechanical filter. Looks kinda poor but works solid.

One more addition:
They were bought by FPS (good ol' Floating Point Systems), in 1988, with the
resulting company being called FPS Computing. The FPS 500-series machines
are actually Celerity 6000-series minisupers. This company was another
company like Convex, Alliant, Sequent, etc.

hello !
someone offered my a Celerity computer from 'GEI Rechnersysteme'.
it is mounted in a 19" rack and has a built in tape drive.
unfortunately they cannot provide me further information.
so I would like to ask you on the classiccmp-list:
- where can I get further information about this machine ?
- what hardware is in it ? [bus, cpu,...]
- what operating systems run on it ?
- should I take it or leave it ?
thanks for help,
Andreas
