If you are replacing an existing dead P/S, you have the connector(s) you
need to connect to a 9VAC transformer. If not, the connector is similar
to the old AC power cables which were used on the '80s portable cassette
players/radios or Remington electric razors.

I was able to make it work with an NES power supply (9VAC 1.3A), but anytime I tried to use the datasette, the screen would flicker and all operations would cease. I assumed this happened because the current was too low (high enough to drive the Vic, but not the Vic and the datasette). According to the 8-bit FAQ (in Mr. Dellett's post) this is probably correct -- the lowest-current one listed there uses 1.7 amps.
Thank you for the response!

Hi All:
I have just returned from the University of BC here in Vancouver. They
called me to see if I was interested in purchasing two mainframes that
went surplus as of June 30th, 1988. They are open to offers, and do not
want much money for these.
The machines can be described (basically) as follows:
First, an IBM Mainframe, ES/3090 400-J, several hundred MB RAM, many GB of
DASD (thats HD to us non-big iron folks), 1/4" tape drives, cartridge
tape, consoles, 3270 and newer terminals, chiller (system is water
cooled), power supply unit, media, etc. This system runs MVS, also MTS and
was the main computer for a campus of 20-30,000 for a period of about ten
years. The machine is circa 1986 and is available to anyone who wants it,
and will take it away!! I'd suggest that two to four semi-trailers would
do the job, depending upon how many peripherals one wishes to acquire.
The current front runner on this machine is a local scrap dealer who is
going to chop up and recycle the machine for its metal content. :-(
I've contacted Paul Pierce, mainframe collector extraordinaire, but he is
unable to take the machine due to space and time contraints. Any other
takers?
Also available:
A Hitachi (apparently) mainframe system, model HS 7023, terminals, tape
drives, racks, disk storage. This system was smaller (about the size of a
large VAX 750/780 installation), was also in working order as of June
30th, and is available. It sort of looked like a mini to me but the
computing centre staff refer to it as a mainframe. Offers, you pick up.
If there's any interest then please email me and I will be able to provide
you with further information, and put you in touch with the surplus folks
that are handling the disposal.

If it is only for the drive, any DISK ][ could be used
for replacement parts.

Your last msg did make it. Do you need 8 bit, 16 bit, static, dynamic,
16 bit address, 24 bit address, mixed RAM and ROM, do you have a boot
ROM of some kind, what CPU card are you using, do you have a front
panel? I'll check and see if I have anything to spare this weekend.
The catch is the S-100 boxes are piled 6 hi and chances are the spare
card is in the bottom one, plus I have to unscrew each top to look
inside.

MS tries to catch up with WinNT - so the Users might share

Hi guys! I'm telnetting into my old accound from a bookstore in Denver...
Just wanted to let any locals know that there is an NEC APC (Advanced Personal
Computer) available at the ARC thrift shop at 10000 E. Colfax in Aurora. It's
an older machine, looks like a VT-100, with a monitor and 2 8" floppies in the
main unit. Not sure how much (tag was torn.) Also there is a Franklin Ace 1000
and a Commodore PC-20 III. And an IBM DisplayWriter.
So far, I haven't picked up much, but I did get a Mattel(?) Odyssey, to "TV (that is, two (2)) game consoles, and an Atari Pong game in the box. That's
about it; I'm off for more sightseeing.
