In taking inventory of my accumulated Unibus and Qbus cards, I
have discovered an Emulex Unibus something. Researching it on
the Web, I also discovered a place here in SoCal who advertise new,
used and refurbed Emulex (and others) adadpters and devices:
Fidelity Computing www.ficompinc.com and look under the
'Emulex' listings. There are Unibus SCSI cards for $400..
Anyway.. this particular Emulex Unibus board has the model number
SCO210101-CXL sub number 4039 H. The abovementioned website lists
a part number of SCO2 as a "Unibus Disk Controller" and has a price
of $150, but that's all it says.
The card has one 60 pin and two 36 pin connectors and has 12
18-pin proms along the left edge.
Anyone have any pointers to info on this card? Or even better,
manuals that I can bribe to have copied?
I'd send this card in to Emulex, but it's warranty expired in
September of 1985. :)
Cheers

I think you're right. I distinctly remember (must've been 1982 or so)
an Atari commercial with a family of aliens playing Asteroids on their
2600 when the mom comes in and tries to get them to eat by saying
"Biddy Biddy? Biddy Biddy?". When was the Buck Rogers series
originally on?

I have a hazy memory of CESI, but I never heard about replacement PDP-8
CPU boards before. Besides the obvious issue of cost, why were these
made? I can see that with a 1.2uS cycle time, it's like a hex-high KK8E,
leaving you lots of room for peripherals, but is that the only benefit?
Did they integrate any I/O into the CPU module? What's the 40-pin connector
at the top of the board for?
As for scanning issues, I'm not one of those people to harp on bandwidth
since I feed off of a cable modem. I'm personally fond of compressed TIFF
files or PDF for B&W, and depending on if the document is for screen or
printer 75dpi to 300dpi for regular scans.
Thanks,

I have a lot of the kid's computers, (Atari, Commodore, CoCo, etc), which
I am trying to keep alive. Does anyone know if I can substitute high
quality music tapes in place of computer tapes? Or where I can still
find computer cassette tapes for sale?

Mine too. It is possible, but horrendous, to reverse the drill bit, get
some abrasive slurry, and *grind* a hole through a magnet. You gotta need
it pretty bad, and I'll lay odds no-one will build a core memory board this
way.

The module I have is the notepad one and I've been trying to find a manual
(or copy) for it as well as for the main unit.

Do you have any spare module?

Any actual info on the pinout of the cartridges? It seems like this unit has
hacking potential...

The dates I found indicated 1975.

The NiCads in mine had started to run (whitish crysltals all over the bottom
of the case) that's why I had to replace them.

Huh? My 1520 uses ballpoint nibs.
Does anyone have any software for this? Somewhere on a disk, I wrote
a BASIC program to plot a function that resembles a black-hole on a
spacetime grid (and the unknown mass coordinates for Starcross), but
I have never run across any other programs for this device.
Does anyone out there have any software for it? (I don't recall seeing
any on ftp.funet.fi).

Please describe this more fully. The Spartan Mimic was "the" Apple ][
emulator for the C-64. One of its "features" was a board that sat between
the drive cables and the 1541 PCB that used relays to cut over certain
signals, and also provided for a 20-pin Apple disk connector. You could
stick an Apple disk in the 1541, read it from the Apple side, then swap disks
and read a C= disk from the C-64 side. AFAIK, the 1541 board was not
required, except perhaps as a way to tap power (i.e., the Spartan board was
essentially an Apple Disk ][ to bare-drive interface/analog board.
I was a beta-tester for the Mimic in, ISTR, 1986 or 1987. It was too little,
too late, for too much money. I did get to keep the unit. I still have the
case (empty) and the PSU (recycled into powering external SCSI disks), but
I can't seem to locate any of the innards (I think it died after a while).
My "greatest" accomplishment with it was attaching a real Apple disk for
D0 and playing Spellbreaker on the Apple at the same time as Enchanter on
the C-64, using the same keyboard and monitor, switching between the two
CPUs when one was loading the next part of the game. The documentation
described being able to write programs on each CPU that could talk through
a register window and do some multiprocessing, but I never wrote any nor saw
any for it.
Cool hardware. Dunno what you found, but it _might_ be a former part of one
of those.

The "rotate around at many different orientations" is also
important for a thorough degaussing. Unlike electric charge, which
doesn't have a direction, magnetization *does* have a direction.
The really professional degaussers will automatically rotate and diminish
the magnetic field in a pre-programmed sequence. These are very large,
however, and cost lots more dollars than the ones you buy at Radio Shack.
With many modern high-coercivity media, you can't do a really thorough
job of degaussing with a small degausser in any event. They just don't
make a large enough field.
