I purchased a while ago some 500 new bulk packed green 5.25 DD disks for my
c64/IIgs systems that didnt come with any sleeves. Anybody know of a place
that sells just the tyvek sleeves for 5.25" disks?
I bought an HP 9111A digitizing tablet on eBay for my HP-85
and I was wondering if anyone has the software needed to drive it.
Alternatively, if anybody has info on the communications protocol
used by the 9111A to talk to the HP-85 over the HP-IB bus, please
let me know.
Thanks

hp 1727A Storage Oscilloscope (275 MHz) with manual, does not power up but
for $10 no complaints.
IBM mag system (typewriter and reader).
Sun Diagnostic Exec 1.2 for 68020 & 68030 1/2" tape and manual.
LOGICAL QUV-T8 UV EPROM Eraser

manual.
Feedback Temperature Control MAT855 & MIC955 module for microcomputers with
manual.
DMS tele-sports mini handheld gaming system.

Unloaded a ton of stuff in storage here and will update list as I find more
good stuff for the museum.
Hello all,
I have the following 8" floppy drives available for $5.00 + shipping. The
$5.00 covers the cost of a brand-new box, shipping materials, and my time to
pack/ship. These drives are working pulls, but have not been tested in a
few years. I may have manuals for the Shugarts, so ask if you need one (no
extra cost).
In order to be fair to digest and international users, I'll take emails from
interested people until Tuesday, August 5th at midnight. Then I'll randomly
choose people to ship the drives to. Please email OFF-LIST, and include a
ZIP code or country so I can quote shipping.
Shipping will be by USPS, from ZIP 01473. Shipping weight is approximately
25 lbs. per drive. I will weigh them and give an exact shipping quote when
I determine who gets them. I CANNOT combine more than one into a box
because of size/weight constraints (i.e., too big and heavy for me to
carry!). You can go to www.usps.com and get a shipping estimate.
Here's the list:
- Qty. 1 Shugart 851
- Qty. 3 Shugart 801
- Qty. 2 Shugart 800-2
- Qty. 1 Qumetrak 842
- Qty. 1 Qume DT/8 (this looks like the 842, but I have no manual to tell
the difference).
Thanks!

Put an ST506 controller into a PC. ST506/412 was the defacto
standard on PCs until IDE. although most PC people erroneously refer to
the cabling and interface as "MFM". The controllers used by IBM in the XT
were made by Xebec.
Once you have a controller and drive in your PC, you can write the code to
read and write sectors to be able to copy a drive.

It would be easier to use basic SCSI commands to talk to the S1410 controller
directly. I have the documentation on line, and as long as no other peripheral
is on the SCSI chain, it should work fine (SCSI is a superset of SASI)
When you write the copy program, remember to have some fallback strategy WHEN
you read a bad sector (filling with ascii "BAD SECT" for example) since you
may not get any data back.
You'll also need to figure out the disc geometry, sector length, etc. since
you have to set these parameters into the S1410 before you can do anything.
This may require some experimentation, but it isn't likely that they would
have used anything other than 128,256, or 512 bytes/sector.
the S1410 manual can be found at www.spies.com/aek/pdf/xebec/S1410Man.pdf

Learn enough about the system to extract the code needed to do
a bootstrap. It will be worth your investment in time. The amount
you'll learn will be more valuable than the boot strap code.
The simples bootstrap is with some serial input to drive. You
should get a second drive to fiddle with, that can later be used
as a backup.

I hope this isn't too commercial for the list, but I have a couple of
machines which use these so I figured some of you might need some, too.
"720K" 3.5" DSDD diskettes, 10 per box, new old stock
$1 per box of ten, minimum 10-box order, shipped UPS through my commercial
UPS account, buyer pays shipping
I'll run them through my store so I can take VISA, MasterCard, Amex or
Discover
Sorry for all the conditions, but I'll have to buy a *mountain* of these
and need to know that I can move a few before I commit to the purchase

This is a bit modern for the list, but I'm hoping someone here has some experience. I've just been given a pair of BA356 enclosures, and the one has 6 empty DS-RZ1CB-VW SSB's. The shelf itself is a BA356-KD with BA35X-MD 2X fans, and a BA35X-MH 16-bit I/O Personality Module.
My question is, while the DS-RZ1CB-VW SSB's are intended for 4.3GB 7200RPM *SCA* drives, can they handle 9 or 18GB 10,000RPM SCA drives?
If nothing else, I can always fill the shelf with RZ29-VW drives, but would prefer some 18GB drives if possible (I suppose I can always get some 7200RPM ones off of eBay).

Don't need that... but, anyone got any microchannel ethernet cards? I have an IBM PS2/95 server, with only token ring. It's that or I have to build my own token ring segment. Kind of a drag...
Thanks,
Mark

Yow! I drive by the site every now and again and shed a tear for
what was once a wonderful place to lose an afternoon. Back around
'89-91 I worked at MIT and Eli's was a prime source of parts for
labs with tight hardware budgets to repair/upgrade their ailing
MicroVAX II's and such.
I remember wandering the shelves and seeing RX0n drive cabinets,
whole pdp-11/44's, and other goodies that I didn't do anything
about. What I did do was buy an SGI Iris 3130 with monitor -- nobody
seemed to know what it was, but I got it to boot. I believe I paid
$2k for that thing with 20" color monitor, and hauled it home in a
friend's car.
Fooled around with that for a couple months but something in the
monitor went, probably a flyback. I decided by that time that I
needed a Sun for a project I wanted to do when I returned to college
(anybody remember UCB's Sprite?), so I sold the thing with a dead
monitor for the same price. Who knows, maybe I could have gotten
more, the thing was loaded with bitplane and Geometry Engine
boards. But the weird System III derivative OS really put me off at
the time.
Manys the time I've wished I could go back in time and raid those
shelves, or browse through the tables of electronics parts...
