I've got a GRIDcase 1530 here, with no power supply. I tried using one
of the cheap 9.95 "multi-voltage, multi-attachment" generic power supplies
I have here (use it to charge my mavica battery).
Power supply's max is 12V. The GRiD says 16V, but someone told me they'll
run off of 12V (automotive voltage) too.
When I plug it in and hit the switch, the status lights above the keyboard
flash on and off rapidly (continuously) in conjunction with a "ticking" noise.
My guess is, the power supply isnt up to snuff with what the laptop wants.
Anybody got a power supply (and/or an entire system WITH power supply) for
a 1530 for sale? In fact, I'd be interested in ANY GRiD hardware that
anybody on this list has for sale.

I'm not at all sure what you've said here, Allison. Aren't we in agreement?
The 2101 was a 1k-bit sram organized as 256x4 with separate inputs and
outputs.
The 2102 was a 1k-bit sram organized as 1kx1 with separate in and out.
The 2112 was a 1 k-bit sram organized as 256x4 with common ins and outs.
They're all different, but whoever wrote the message to which I attached
mine already knew that it was a 256x4 in a 22 pin package 0.400" wide.
Additionally, there was a 2115 which was a high-speed (25 ns) 1kx1 sram with
open drain outputs. I saw few applications for that one, however. It had a
cousin, the 2125, which had the same pinout and architecture, but had
tristate outputs.
Things got muddled when the iNTEL folks started using unused numbers in the
1K-bit family, e.g. 2114, for memories larger than 1k-bits. The 2114,
however, was just a microcomputer-compatible (slow) version of the already
widely used 2148/49, which was a fast (35-70ns) equivalent to the 2114.
They also made the 2147 which had the same bit count as the 2148/49 but with
a 4kx1 organization with separate input and output and pinout compatible
with the much slower TMS4044.
The PET 2001 was pretty early among the production microcomputers, hence may
have come along too early to capitalize on the high-volume production of the
4K-bit srams.

I'm not certain I know which of the items on my list you're referring to ,
but I've learned that I have only five drives to deal with, so I'm not
worrying about making a board at this juncture. I've got to adapt from two
fairly standard connectors, i.e. 40-pin IDE and +12, 2x GND, +5, of which
the +12 isn't needed, to that 44-pin connector on the notebook drives.
The best arrangement I've seen is is a dual-row by 22 with short soldertails
sticking strainght out from the connector in such a way as to facilitate
soldering to a 2-sided PCB. That, at this point would work for me. I have
an adapter between the two connector types but that's just a mite too large
for my application, particularly since it restricts my ability to mount the
drive such that it's centered on the PCB, half protruding through the top of
the board and half through the bottom so as to avoid interference with the
adjacent cards.
So, John, did you find they were back-ordered on the ribbon cable? Since
I'm in no hurry, perhaps it doesn't make much difference. You're right
about the suitability of 50-conductor ribbon, though.

I think the basic number you're looking for is "2101" from the same 1K
series as the famous "2102" which is a 16-pin 1kx1 with separate in and out.
The 2101's I have are not fast enough to meet the 200ns spec. However, not
much of anything that was readily available at the time the PET model 2001
came out was that fast. Either it was quite a bit faster, e.g. 2147, 2115,
etc, or it was slower, e.g. 2114, 21L02, TMS4044 etc, which were typically
450 ns at that point in time. Those 450 ns parts worked handsomely with the
1 MHz 6502. Perhaps you'd be able to use a 2101.
Let me know if you think that might work for you. I've had my small supply
(maybe 4 pieces) since back in '76-'77 when I got my original 6501, though
I've never used them for anything.

Maybe somebody can clarify something for me. I had an 3100/M38
a few years ago and had to buy a disk for it. At the time I
bought a Quantum 210 MB drive. In order to use it with VMS
I had to get a special utility that I ran from my PC with the
drive and had to turn off the "Write-Preallocation" feature
off on the drive.
Is this strictly a VMS thing?
Is anyone interested in acquiring this rack mount communications
controller in new condition with manual and disks. A very casual
reading of the manual suggests that it is intended to provide
access to IBM and compatible machines including Systems 360/370/3
as well as 4300, 8100, system 36 and AS/400.
Communications protocols include Synchronous, SDLC, SNA, BISYNC,
X.25, and 3270 Emulation.
I would like to get at least $20 plus 1.2 x shipping for it, else
I will strip it and send the metal off for recycling. In any
event, it is gone by the end of March!

I am still trying to track down the Motorola structured assembler for
68000. I found another lead in a 1983 Motorola software catalog. Motorola
had the assembler, linker, and Pascal compiler available as "Pascal source
code for the IBM 370 with Pascal VS2 on 9 track tape" (but the requirements
said "any operating system with FORTRAN").
Do any big iron folks have this?

I have a few similar drives, but I am also considering getting an Amiga
1200 just to run Deluxe Paint. Is it an easy install into a hard-disk-less
Amiga 1200?
