I'm lately rather into retro gaming, and I stumbled across this gem:



Apparently this was the IBM 2250 Graphics Display, and it seems almost like an early console of sorts. I know that what happens on these is usually serious work involving graphics, but who said they can't be used for playing some games? It comes with a keyboard and some programmable buttons on the left, and a built-in, light-pen controlled screen. It would seem like the perfect retro console.



Here's some evidence that it actually played games.

These are quite rare even when they were actually used, so I'm not on the lookout for an actual unit, which would need a mainframe for proper operation anyway. I'm looking for some kind of emulation software.

Look at all the fun happening:
 
Only requires a 360 - just a few million bucks. I helped finance one for the state government - not including the 2250 - it weighed in a bit over $3 million. ("Big Iron")
 
Very special code to operate it -- GAM (Graphics Access Method) - - NON ascii (EBCDIC) and vector processing commands
(move from x,y to x2,y2).
 
EBCDIC!!! Translation Tables...OMG...I'm going to have bad dreams all night!!
 
Would a Model 20 do? It's the cheapest!
 
Not likely as there's a channel controller about the size of refrigerator also required.
 
Look, this is all fun, but if you could find it, it requires three-phase 240 ac plus a controlled air environment. The device will never operate as a console so it's time to give up on it.
 
Whilst research something else I came across this post from 8 years ago. As is the way of the world for we old techies there’s a good chance that many are no longer on here but I thought I would add this by way of completeness. Although the 2250 could be attached, rather expensively, to 360s it could also be attached to the IBM 1130. The 1130 was a scientific machine and we had them in our Data Acquisition and Control Systems Centre, alongside IBM 1800s and IBM System/7s. When the 2250 was attached to the 1130 it could be used, when not performing real work, for playing a number of games. These, iirc, were Tanks (a battle game of calculating trajectories/distance), a Table Tennis Game, a Star Trek game, a Go type game, a Reversi type game, a Life Game, and one which printed a rather unusual "centrefold" type calendar. With two 2250s attached to the system it was possible to have multiplayer games as opposed to one player v the system with a single 2250. And yes, I did spend many late nights playing these in a dark corner of a computer room. 😉
