Joe:
If you're ever interested in unloading this, and/or the disks let
me know.
If you ever get a chance, I'd love to see some pictures of this beast!

Yeah, I was a little surprised to see in their FAQ's that they say it is
NOT recommended for electronics use... considering the commercial CLEARLY
shows a person using it on electronics!
I guess its another example of do as a I say and not as I do (eh, who am
I kidding, all these "as seen on TV products" use them on TV in ways that
they tell you not to use them)

Are these Z80 TRS-80 systems, or the 68000 systems? There actually were some
S-100 like systems (same connector, different board form factor) of the
model 16/6000 series. They were used in large (for the time) dialup systems.
I think they had 2+meg of ram and 2 or 3 four port serial cards. I have
never seen these, only heard about them. Some were even modified to run
68010 CPUs. There are instructions out there somewhere for this mod, but
no-one seems to have them readily available. They "lore" is that these
instructions were saved in the swap area of one of the install boot
diskettes. I was able to find and extract the games that were hidden there,
but never these instructions.

Hello everybody!
You might remember my question about transport-locking HP-IB Harddisks last
year; Al Kossow kindly added the installation manual to his Bitsavers site.
Today I had a go at the drives; two of them (the 7912 and the standalone
7908) were absolutely no problem to do using the information he provided.
The rackmount 7908 however was not - it looked very different inside; a
completely different technology, it must be a later revision. No die-cast
HDA taking up the whole width of the housing, merely a modernish smoked PMMA
(?) hood covering several 8" (if so large) platters in the front-left corner
of the assembly. No accessible spindle drive or actuator to be seen and no
obvious way to lock everything in place.
Can anybody please shed some light on how to prepare this unit? We don't
want to risk transporting it as it is because the head assembly already
moved when I only pulled the drive out of the rack.
TIA,

Yes, they are Z80 TRS-80 systems - the guy basically replicated a TRS-80
in homebuilt S-100 cards. I should have pictures up within the next week
or two.

I have some 400 fingers available for Genicom line printers.
They should fit the models 310/320/33/ & 340.
About 25 are individually packed in platic bags, the others are
in 2 tubes with approx 200 fingers each. There are also 3 extractor
tools and some instruction sheets.
Free for the cost of postage.

Hello,
Is there anyone currently working with Amdahl equipment?
I've got four spools of nine-track magnetic tape with various
labels (AMATS, Amdahl Architectural Test Systems,
Extended Memory Support, etc). I believe these were used
by Amdahl field support.
You can see the labels (and some Amdahl binders) at
www.decodesystems.com/amdahl.html
While I've read "There Are No Electrons" (written by Kenn
Amdahl) I don't happen to have any Amdahl equipment -- so
if there is anyone with an interest in these tapes please contact
me off-list for trades, etc.
Cheers,
Dan

Another good auction! For my $20 hard-earned dollars I picked up:
a tabletop 9348-012 IBM SCSI (differential) 9-track tape drive (woohoo) so I
can now make software tapes for my PDP's on my peecee!!
Anybody have a manual for this beast?? I will gladly pay copying and mailing
costs!!
an Ohio Scientific 600 Single board computer (circa 1980) w/ power supply and
cassette software along with these manuals:
Servicing Data for Computer Boards 600 & 610 (challenger series)
Assembler editor and Extended Monitor Reference Manual (C1P, C4P and C8P)
Basic Reference Manual (ROM 65D and 65U)
65V Primer
C1P and C1P MF Introductory Manual
The Cip Users Manual
Also a couple of IBM AT's (for the MFM drives)
A couple of SGI Indy's (r5000's)
miscellaneous peecee computer parts
All-in-all a good day!!
Cheers
Tom

Please do not read this sig. If you have read this far, please unread back to
the beginning.
The newer IEEE-488 chips emulate either the uPD7210 or the TMS9914 or both,
so their docs might have the info you want. You should be able to find the
following online:
National Instruments TNT4882 Programmer Reference Manual 320724-01
National Instruments NAT7210BPD datasheet
National Instruments NAT9914 Reference Manual (9914 but with 7210 mode)
ines ieee488.2 iGPIB Hardware Manual
Computerboards CB7210.2 data sheet
Also, the source for Linux/NetBSD/FreeBSD IEEE-488 drivers might be helpful.
