If you recall there was a discussion about tape catridges that could
not be read because their coating was falling off.
I was thinking, what if we reverse the tape, so that the magnetic
head come in contact with the plastic backing and not the oxide.
Would it be possible to read the data then?
Obviously I am talking about a one-off operation, just to get the
stuff off the tape.

Any ideas as to what it is, and if it can be made to do something
interesting?

Sounds like some variant of the 9817 / 9000/210

you'll find some field service manuals hiding under "Product Documentation"
there
googling 50960A turns up "200/SRM Server"
SRM is a 700kbit networking scheme which uses the 5096x DIO-I interfaces
So it was probably the server side box for an SRM network

Hi
Would the stuff used for magnaflex work. This is available
through most machine shop supply houses.
Another thought would be to stablize the media with something
like art spray ( acrylic ). A vary thin coat should only
reduce the highs a little but should stablize the coating.
I'd try it on a spare tape first.

That assumes a fair amount of software working on the 11 side.
Has anyone written something dumb that could squirt a block-level
mass storage image (dealing with bad blocks..) through a DELUA or
DELQA to a destination at the raw packet level?
I've been thinking of doing a ethernet nub debugger for Qbus
machines that would work that way (which I why I just picked
up a DELQA..)

Does your friend have any recollection of a Fabri Tek memory expansion
for a DEC PDP-11/20? This would have been a 19in rackmount with Unibus
interface. I ended up with complete memory unit, interface cables,
some documentation, etc, but unfortunately not the processor. Believe
the memory was removed from a PDP-11/20 but I don't have confirmation.
Regards,
Garry
This raises an interesting question: if you replaced a real PDP-11 that
people connected to online with an emulated one, would they be able to
know the difference?
--
If you were using SIMH you would, since it doesn't perform cycle
accurate simulation. Unless you ran it on fairly slow modern hardware
it would be faster than the original.
This wouldn't be the case for MESS, though, since it is based on
the cycle-accurate MAME processor cores.
I'd love to add this pac to the www.series80.org collection.
I live in Philadelphia, so please send me email with the
cost of shipping and I'll send you the money.
I can scan the listings as bitmaps, but I don't have the time
to make HP-85 programs out of them.
If you require the originals returned to you after I make copies
let me know and I will return them to you ASAP.
Thanks

I've been in contact with an individual representing a university who has a
metric butt-load of software and documentation for various systems.
Primarily DEC PDP-11/RT11, some vax, and possibly some DG. He seemed to key
in on RT11 software & Docs, as well as DEC handbooks, etc.
He is located in north east Alabama, east and slightly north of birmingham.
I would like to see Jerome Fine get first perusal of any RT11 images. The
donator's primary concern is that this load of stuff NOT hit E-bay, and
instead be scanned and archived for the public. Resting in private hands is
ok, as he'd like to see the stuff get use as well. He just doesn't want to
see someone turn a buck on ebay with it. I suspect most if not all of us
would agree to this.
So, anyone in north east alabama want to organize a pickup and distribution
(probably to Al at some point for archiving)?

Going through the front of my container I found a Stride 440 that I
need to sell. Made in Reno, Nevada!
I believe it is a 68020 machine with 3 megs of ram and a 60 meg MFM
Fujitu hard drive and is a decendant of the Sage running p-system.
Looking at the cardset it appears it might have been upgraded from the
original 68010 to a 68020. It also looks to me that the modem chipset
was never installed.
It has a three board set with a smaller board in the middle of the
larger two boards. I think the small one is the 68020.
The case shows some damage however none is visible to the electronics
or drives. Missing a floppy drive cover, from the layout of the cables
a second was never installed.. I have not powered it up and am not
going to, I will leave that up to the new owner.

More and higher res pics avalable
Given it is unusual I thought I would offer it to the list first. From
my google search it is a fairly rare machine. I could find no pictures
at all.
I need to sell it so I am open to offers. Anyone interested?
Out of the dig is an original 5150 CPU, a 5 slot 2nd gen two floppy,
CGA, AST mem & I/O.
A Vector MZ5 S100 MF with 8 cards I have yet to inventory, no drives.
On ebay at the moment is the last Teletype model 43 I have, sale
number 5210816476 ending in a couple of days.
