Hmmm, now that sounds familiar to me. Is it a tiny little card? If so, it did
indeed come with GEOS and you had to put it in the //e to get the mouse to
work. The copy of GEOS I got at the time had a mouse included and had an option
to get 3.5 disks which I did even though I only had 5.25 drives at the time.
My copy of GEOS is around here somewhere and I got several other BS
applications for it as well.
I found a couple of these in the dregs of the bazaar remains, and am
curious what they do. Google showed they were used in the Apple IIe, but
that is all I've been able to find. Anyone have more information about
how they were used? Thanks!
C'mon folks, let's all tone down the politics and rhetoric and attendant
attitudes. Things have been going quite well, let's not get into this kind
of diversion.
Move along... nothing to see here...

Since the 380Z seems to be popular at the moment, does anyone have info
on 2 bits that are not properly described in the Information File?
The first is the dual cassette controller. The pinout of the 7 pin
cassette socket is given, as of course is the schematic of the VDU board
that contains the cassette circuitry. The controller seems to contain a
couple of relays to control the recorders (were these powered from the
system 5V line or a separate power supply?) and switching to allow either
one recorder to be used, or two with one used for recording the other for
playback. It's possible to make some guesses as to how it was wired, but
some real details would be nice
The second is the SIO-2 board. This was a bit-banged serial port using,
IIRC, 3 lines of the user port. 2 ouput lines for TxD and thr reader
control relay, one input for RxD. At least knowing what port bits were
used would be a help...

Our annual Bazaar was held today with all the leftover stuff now at my
house ... briefly! In searching through the stuff this afternoon, I
found several boards that I couldn't identify. One is labeled "FlipFlop"
and the other "Inverter". I put up a picture of both sides of the
FlipFlop at:
http://www.rain.org/~marvin/flipflop.jpg
While not obvious from the photo, it does look like the board has gold
plated traces. Does anyone know what these things might have been a part
of?

Has a site devoted to old IBM 80-column punch cards, and if you send him an
empty pre-addressed envelope with postage (about 3 ounces, I think), he will
send you free samples, a stack about one-quarter inch thick (a couple dozen
cards).
I have two AT&T unix pc 7300 systems, with manuals, books on unix, and lots of software and an extra monitor plus some upgrades, looking for a good home.
If interested e-mail me at dan.howard at adelphia.net with offer.
