I need to clear a little of my collection (that
or hire a divorce lawyer) so I want to move a few
things I have multiples of or just don't have the
time/skill/interest to fool with. So, first on
the list:
HP-150A
Fully functional, with keyboard, _NO_ HP-IB peripherals
or cable.
There were leaking batteries in it, but the corrosion
has been cleaned up/neutralized, new batteries installed
and it works fine. Will provide MS-DOS 3.20 boot disk
(single sided works with 9121 disk) with PAM and utilities
if desired.
Best offer by 4PM June 1.
Thanks!
I finally got my hands on an osiclloscope! 10 CAD at a garage sale this
week-end. The beast is OLD, but works! I can't find a model number, but
it says "Push pull" and "Extended range" on the front. I bought it with an
course text book from Institut Teccart Montreal dated 1944 (in French).
Last couple of chapters are about tubes, which is nice because my
knowledge of tubes is limited.
OK, so it's not a computer, but, uh, I'm going to use it to debug
computers! Yeah, that's the ticket. But it doesn't go to very high
frequencies... SO I'm going to use it to debug 9600 baud serial
connections! Yeah, that's the ticket.

As others have said, you need disks intended for single-density or double
density, not HD. I've also met one 1541 owner who swears that disks
without hub rings won't work in his drive (and never did) because the
mechanism doesn't grip them tightly enough (though I'm fairly sure that's
just due to a soft spring or a missing screw on the frame somewhere).

Hello All, I've got a copy of Volume 2 of the ROM Kernel Manual (Libraries
and Devices) and the complete notes (a big 4" binder full) from the '88
developers conference. (It even has the presentation on the fabled A2000
Transputer version!) Anyway, they weigh 12lbs and are available for trade.
I've also got the three volume set Cromemco ZPU, 64KZ, and 16FDC manuals
available. (those go as a set _only_ please)
I'd like to get some DEC documentation if I can. Things on my wish list are:
Any Q-bus VAX processor Technical Manual (KA6xx) (except KA660)
PDP-8 or PDP-11 handbooks
Prints for an 11/34
RLO2 manuals
Prints/Manuals on the TU60 DECCassette
DRV11 Users Guide or Technical Manual!!!!
CXA16 Users Guide or Technical Manual

They have LEDs.
I soldered them in myself when I put together my Altair kit :-)
BTW -- a lot of the popular history of the Altair is wrong.
I have seen several "official" source list the original price at $375.
It was MUCH more expensive.
I have my original invoices somewhere ...

Subject: Altair 8800 front panel lamps
I've just been reading "Computer: A History of the
Information Machine", by Martin Campbell-Kelly and WIlliam
Aspray. It mentions the Altair 8800 (on page 240) and
describes the front panel:
When loaded, the program would run; but the only evidence
of its execution was the change in the shifting pattern of
the neon bulbs on the front.
Neon bulbs? Did the Altair really have neon bulbs on the
front panel? I would have expected LEDs -- can anyone
clarify this, please?

Welcome to the list Bob.
There are a number of HP minicomputer collectors on this list including
myself. While I don't have anything from the 60's, I do have several MPE
systems and 5 or 6 early HPUX boxes.
I'm always looking to add interesting hardware or software to the
collection.
Once again, welcome.

Ta! Well, Dodos have been extinct for a long time, but I couldn't think of
something that was *nearly* extinct. Having said that nigh on 80,000 Lisa
1's were sold, though most were apparently upgraded to Lisa 2s since the
upgrade was free. As for rocking horse shit, have you ever seen any? :o) The
other analogy is 'Hen's teeth'. The Sord M5 is more uncommon over here than
the CGL M5 which was the European version. I suppose I should change the
picture to be my stretched Memotech MTX512 which never officially made it
out of the factory.

TBH I thought Paving slabs might have caused more confusion than, say, dodos

I have some AC adapters I bought in a lot, I gave $1 each for them and
pulled what I need from them. Input is 120VAC 60hz 800ma and output on a
standard round/tubular "coax" connector is 16VAC, 4A. Fused with a 5A/250V
fuse built in and changeable if blown. They're bricks with about 3 ft of
wire to the 2 prong AC plug and about 3 ft to the coax adapter. Brick
measures about 3" wide, 3.5" deep and 2.5" high. Made by Eltron with the
part number 808061-001.
I have 4 I need to get rid of at $1.00 each plus applicable postage. They
weigh 3 lbs each. Someone can have them all or just 1, 2, etc. I'm in
central KY in zip 42726 in the event someone wishes to calc shipping.

I finally had a chance to look at that SCSI floppy drive I mentioned on
the list a few weeks ago and a few people wanted to hear more about.
It's interesting. The drive is built by PLI and named the TurboFloppy
1.4. It can only read and write 1.4MB disks, no 400k or 800k (and I
complained about USB disk drives not being able to!).
The manual keeps stating that the drive does not have an auto-eject and
the picture on the box shows the drive with an eject button, but the
drive that I got simply has a paper clip hole like any other Mac drive,
so presumably it supports auto-eject.
I've been trying to get the drive to work with an LC 580 without much
luck (the other older SCSI Mac I have handy is my Color Classic and I'm
not about to hook a strange drive up to it). I've tried various SCSI
ID's without any luck. With termination turned off, the computer boots
as if the drive was not even attached. With termination on the drives
attempts to read the disk at startup and then the Mac begins to boot,
hanging at the 'MacOS Starting up...' screen before any extensions are
visibly loaded.
It strikes me as a SCSI problem, so I think I'm next going to try it with
a hd-less Mac Plus or SE (something from around the time period it was
made) and see how it reacts to that. The manual mentions a disk
containing the files 'TurboCache' and 'TurboBack'. If anybody should
have them I'd love a copy.
Reading the manual, it appears the TurboFloppy was intended for Mac users
who didn't have floppy ports but needed a second 1.4MB-only floppy drive.
I'm not sure who that would be. My plan is to use the drive as a quick-
and-dirty way of loading software (particularly network software) onto
Macs with bad floppy drives.
