Thanks. Yes, that is the same sort of thing. One difference (perhaps
an improvement) in the Genrad digit-display modules is that the
grain-of-wheat bulbs are just slid into tubes in the back of the
module -- their contacts poke out the back of the module and mate up
with spring-loaded contacts in the display chassis. Also, the modules
slide out from the front of the unit, so replacing the bulbs is fairly
straightforward and can be done without soldering.

I just thought that the group might find it interesting to know that the P-3
Orion carries, as part of the electronics suite, a Data General Nova 3.
Nifty, isn't it? Just in case anyone thinks I'm talking about the avionics,
I'll go ahead and say that I mean the Nova 3 is part of the ASW suite.. Oh
yeah, ASW = Anti-Submarine Warfare, which is the Orion's primary function,
though it also serves as an all-purpose patrol aircraft, and it can even
carry out anti-ship missions (it has underwing hardpoints for Harpoon cruise
missles). At least I seem to remember that it was Harpoons it could carry,
at any rate, it is capable of carrying some sort of missiles ;p

yes and yes. It was a custom circuit but the circuit was a 4bit
microprocessor that HP did for their own use. Bell labs also had
a really interesting 4bitter they used in ESS (early).

Not all the same pin functions. Some internal differences, V40 has
async serial IO for example. Nicer part.

Sounds like 220v 2-phase. Two hots and one neutral/ground. If its
marked 20A, I believe the connector is probably an L6-20 twist-lok.
Not difficult to wire up in most US homes.
My computer room is running from two APC Matrix 5000 5kva UPSs,
which have 220v inputs and 110/220v outputs. I ran two 30A 220V
(L6-30 twist-lok) circuits from the two outer poles on my breaker
panel to power the UPSs, and everything (be it 110v like the regular
Alphas/Suns/SGIs and such or 220v for the Crays) runs from the UPSs.
Having the equipment run from dedicated 220v 2-pole breakers is
very, very nice. Definitely worth the trouble.

I've just acquired another 480Z, but this one powers up with the words
"Z-NET Firmware Vers 1.1q", and there is a BNC connector on the back.
Would I be right in thinking that this is a Research Machines
proprietary network?
The other good news is that I've got a working 5.25" disk drive with it,
and a single disk, for an educational Viking game. (I thought that the
machine dated from 1984, but perhaps I'm a thousand years out). Instead
of typing "R" to run BASIC from ROM, you can type "B", and it boots CP/M
>from disk, loads another version of BASIC, and then runs the game. I can
then exit the game and use CP/M, which is something I've not done for 15
years.
Oddly enough, the 480Z talks to the disk drive through the serial port.
The disk drive also contains another serial port, which I've yet to
experiment with.
As with my other 480Z, the high resolution graphics only displays in
black and white on a television. I've still not made up a monitor cable,
despite asking for (and getting) the TTL RGB pinouts many months ago, so
I don't know whether it will produce a colour display at all.
I picked up a Sharp QA-25 computer LCD projection panel from a local
junk shop today. The glass/"optics" look just fine (no scratches, just
needs to be Windexed), but I have no manual or power supply or data
cables for this. I remember using one about 10 years ago when in
school, but I dont remember if this uses EGA or CGA inputs (has a 9-pin
D-shell data input).
I'm guessing probably CGA; anybody know specifics on the data cable?
Think I can hook it via straight-9pin-cable to the CGA out port on the
back of a laptop and fire it up? (fortunately I can use a standard
generic wall-wart power supply; it has the specs and connector diagram
on the side of the unit).
Now, off to the office surplus store to get an overhead projector for
$10....

Hi Stan, well, of course eBay is always a gauge of what classic computers are
actually selling for (even if some "collectors" on this list are negative
about it). Take a look at what they are selling for there. Here is a helpful
link to take you right there -

After you've reviewed what they've been selling for over the last thirty
days, click on the "Search Active Items" link near "Sort by" area to see what
they are selling for now. I have many links already setup for eBay to search
for specific computer types. See -

Apple collectors/users are selling out? harrrumph, can you quantify this?
Every computer collector runs out of time and space, I know I do! Since you
offer to buy apple stuff, let's see a price list of what you want to buy.
I've a room full of apple goodies and enough duplicates to sell. How much
money you have?
