Can someone tell me the difference between a Memorex Model 101 and Model
102, and between a Fujitsu Model 2301 and Model 2302?
Thanks.

Wouldn't it just be quicker to remove all the partitions? And if the extra
time is taken to reformat it, the drive can be sold if it is still usable.
In the case that the hole was drilled through it, the drive may have died,
leaving no way to reformat it.

Yes... I had to put securepak on VIDSYS:: and it was the first time the
vax crashed seems there rev levels were a bit off. The machine was never
quite as stable after that until I reinstalled when 5.3-2 came out. The
istability was an inherited problem from the former sysop and system
owner. I still have VIDSYS:: and it's still running 5.4-4 and securepak
though I've trimed as much as I dare off.

First off it's ok, I'm ok!

Sorry bout that. I do tend to be a tad graphlexic the comma should have been
there. It was velocity of 3600. they need 17500+ to orbit.
<(In any case, the use of the word velocity is incorrect. Velocity is
<a vector, as I had drilled into me in Physics class.)
Their forward speed, velocity. I'm a pilot and am quite used to having
vectors influence the direction and speed that is indicated vs ground
track.
<The NASA reference I posted earlier claims:

Downrange groundtrack speed is far lower as the vector is still mostly
vertical (still greater than 60degrees) at that part of the mission.
If memory serves the debrie field was a rough footprint of 20 wide by
80 miles long (for the greater part of the material).
As to what computer... Not sure myself totally. It's my belief that the
IBMs are high level systems management computers and they command the
engine computers. The engines have their own local computers to handle
their realtime needs. Same applies to several other systems.
I consider spacecraft/aviation computers to be both classic and of great
interest. Most are very system and mission specific thus may be nothing
more than sequential controllers. Still, I'm curious.

Gads! I've heard of reformatting old drives for security reasones, but this
one takes the Cake...
Quick and easy way to eliminate a data getting in the wrong hands I guess..
I have this weird drive on an old mini (Honeywell DPS6). These things
have an internal fixed disk, plus, you have to put in a disk pack in
them also. Well, on one of my drives, the belt that runs between the
drive spindle and the motor broke. Where can I find a replacement?
Manufacturer: Magnetic Peripheral
Equip ID# BJ7D3-A
Part # 77708003
Series Code 01
Another thing, I think the drive might be refurbished or something. On
the serial number on one of them, atleast (the working drive) it has a
hand-written "R" after the number.
Anybody who can help me, please do. In fact, if you can help me with
anything about the DPS6 or with GCOS6, I will be forever thankful. From
what I've heard, GCOS6 is sort of a GCOS/Unix hybrid. Should be
interesting.
Also, if by chance, you know of an old Unix variant that would run on
this baby, that could be nice too. I think having an old 7th edition
Unix system would be nice. However, I think having GCOS6 would be
really nice, too.

I doubt it was security concerns, since there are companies which can
recover data from all the parts of the platters which weren't drilled.
Either that, or the security person who ordered it really doesn't know
what they're doing...

Can you get me a monitor & keyboard ?
I goto the thrift stores all the time here in Fort Myers, FL
and have never seen one of these in all the piles of computers I rumage
through all the time. Must depend on where you live.
I guess I will box this thing up and add it to my ever increasing collection
of obsolite computers taking up more and more space in my garage.
And I thought I got a good buy at only $3.50.. <Grin>!!!
