HP1311A is what was used in Galaxy Game
https://www.hpmuseum.net/display_item.php?hw=732
The actual GG controller is a microcoded 2903 bitslice that sits on the Unibus
Supposed to be similar to the VT-48
Didn't James build something (FPGA based?) to play the game?

I may also have the backplane. I'm not as certain of that.

As I understand it, the power for the DACs actually comes from the monitor
(VR12/4/7) and
thus you can’t use any monitor without some additional circuitry to provide the
power to the
DACs.

There was a guy in the Netherlands (I believe) who was trying to sell a
GT40 for $14K with no delivery option.
If I were on the east coast (or just not very busy) I would have higher on
the ebay system just to get the GT40 + monitor.

Right (although I had forgotten that); I listed the 11/05 separately since I
do have data on how much they've been going for - in an attempt to roughly
value the lot. The GT40, however, no idea. (I recall one was

it.

Yeah, whoever bought that got, IMO, a pretty good deal (as I predicted). It's
a fair amount of money, but they got a _ton_ of stuff (probably literally :-).

That actually seems not too bad. If I needed another big project I'd have
really thought about bidding it up.

A tenth the price of the Twiggy Lisa makes that auction look almost
affordable! Final price was $5600.

I'm sure they're out there in bitsavers, but I have an original copy of the
GT-40 engineering drawings. Sometimes it's nice to have the printed copy
to work from.

I'm going to guess that Al had the GT40 in mind. (I wonder if that was named
after the car, BTW?) I don't see anything else there that's _that_ desirable -
the Diablo (aka RK02/RK03) is pretty rare, and
