I don't know if anyone's responded to this yet. (I'm behind in my mail again).
But you might try Accurite Technologies Inc. here in the bay area.
They're at http://www.accurite.com
When I talked to them about a year ago, they said they believe that
they are the only ones in the world still making 8" alignment disks.
They sell both 8" analog alignment diskettes and 8" digital diagnostic
diskettes.
Don't quote me on this but, I seem to remember them saying that the
8" diskettes were $65 each.

Ha! Got it! The drive READY light had one of the little posts broken
off, that's why it never booted! It was drive 1!
But I have to wait till I'm off the clock & my boss leaves before I can
test the theory...

I have an xt class machine with an inboard386 and linux is not possible
as it only has 1meg of ram and the expansion is off the inboard.
FYI the inboard386 was an 386SX/16 compared the the v20 at 4.77mhz it's
fast!

Subject: hhc eproms
Sam,
I didn't hear from you before so can you let me know if there is going to
be any need for HHC eproms? I am sitting on approx. 5000 of them which I have
received a salvage offer of $1.25/lb for and I'm probably going to take,but I
don't want to put anyone in a position where they are requested but now not
available like before with the HHC's.So I would appreciate you letting me
know.
Thanks Mike

You guys may be talking about Switch 1-1 -- which, for an XT, will do this.
Switch 1-2 tells it (both PC and XT) about the presence of the coprocessor.
(I do, btw, have an 8087 in my collection...only one I've ever seen! Even
rarer was the 8088 to 386 SX-16 upgrade board...the world's s-l-o-w-e-s-t
386.)
I'd like to add an 8086 motherboard to my collection...anyone have one?
Well, today I decided to repair the power supply on the Percom floppy that I have for my pair of Model I's. Then, I decided to see if a complete keyboard-EI-floppy setup worked. Therein lies the problem...
It seems like each CPU (a 4k and a 16k Level II) won't recognize either EI (a Rev 0 and Rev 1). Both EI's have 32k of RAM. All that I get on the screen is garbage. I'm turing the EI on first, then the CPU. I've also tried two types of EI cables, one buffered and one not. I can tell which cable goes to which EI because the floppy drive will initialize only with the right combo.
It sounds like I have two bad EI's, but the thing that throws me is that the floppy interface performs a floppy reset.
Does anyone have any clue?? Also, how does one refer to the floppy drive in a BASIC statement? For example, if I want to load a program, do I type LOAD "0:test.bas"? I have no manuals for these machines, and it's been a loooong time since I used one of these.
Also, on an unrelated note, the Altair scans are in, but I'm waiting for Bill Whitson's address so that I can Fedex a tape to him. Does anyone have it??

If any of you have need of a very decent 525 MB SCSI tape drive, check
with this fellow. This is an excellent price for what he describes, though
he does not appear to be aware that DC6525 tapes exist. ;-)
-=-=- <snip> -=-=-
I have the following for sale:
Archive Viper 2525 25583 Rev 002 SCSI tape backup units. Comes in
external
enclosure with Unisys Tape Streamer marked on it. Uses DC-6150 (150 MB
uncompressed) and DC-6250 (250 MB uncompressed) tapes. Tested with
Novastor Tape Backup and Cheyenne Tape Backup and Seagate Backup Exec.
Novastor has software compression to double capacity. Works great. The
unit has a SCSI selector switch and two large 50 pin SCSI connectors on
back of unit. $50 + shipping.
Thanks,

Is the 7-pin power connector on certain VIC-20's the same as the power supply
on the C64?? I just got a couple VIC's of this type with no power supplies.
TIA!

Fairly late-model HP 1000, replaced by the A990 in 1991 I think. I
don't know that much about them but think they are descended from the
HP 2100 and 21MX processors used in earlier 1000s (and would like to
find out more, so corrections are invited). What are the first four
digits of the serial number? That will give you some idea of its age;
first two digits are probably year less 1960, next two digits are
week-of-year.
> It says "hp 7970E"
It is a 1600 BPI 9-track drive.
Is yours in a lo-boy cabinet with the supply and takeup hubs side-by-side,
or in the tall cabinet with supply mounted above takeup? Mine is a lo-boy
but I have used both.

Sounds like HP-IB all right. Note that not all 7970s are.
> I do have a scratch tape, how does one get the tape into these?
As Tony said, there should be a diagram that shows the tape path.
Pop the lever in the center of the supply hub up, and slide your tape
on. Leave the lever up for now; you will be pulling tape off the
supply reel and if the hub were engaged you would have to turn it too.
Pull the tape off the supply reel, threading it around the stationary
post, then the tension arm, then the heads (lift the cover over the
read/write head to thread the tape through), then the other tension arm,
then the other stationary post, then onto the takeup reel.
Hold the tape against the takeup reel -- stick your finger through
the little hole -- and make a turn or two of the takeup reel to get the tape
firmly held on the reel.
Push the lever on the supply hub down to engage the supply reel.
Now you can push LOAD to get the tape drive to scan for the load
point. If it just keeps going and going then there is a problem with
the light/sensor assembly.
ONLINE puts the drive on-line. Won't work unless the tape is loaded.
RESET is "stop what you're doing and take the drive offline".
REWIND is "rewind to load point or 'til the tension arms lose tension
because the tape came loose from the takeup reel".
0, 1, 2, 3, OFF switch the drive's unit number; OFF is effectively
offline. Note that unit number may not have an obvious relation
to the system's device name or number. I don't know much about RTE
(the OS on the 1000s) but under MPE on classic 3000s it was a
component of either the DRT number or the unit number, which were
in turn referenced by the logical device number.

Hope this helps, if you have more questions feel free to ask.

If you jumped buses, it was Atari Stunt Cycle (1976).
Basically a clone of Atari Night Driver
(http://www.pipeline.com/~jhardie/gallery/coinop/nightdrv.jpg), which I
believe owns the title as the original "black & white dots" driving
game. I don't recall what Atari's earlier entry (the first driving game)
called Gran Trak looked like. Another well-known example was 280ZZZAP.
