Look at the photos. Let it rust in peace in mouse heaven. It is just scrap.

Yes, I mean Monitor II-D.
No, CHM does not have a working 1311 drive. The need for Monitor II-D
is for the IBM 1620 Model 2 simulators being written. Monitor I does not
run correctly on a 1620 Model 2 when index registers are enabled and

I hate what epay is doing to our hobby.
I prefer to sell and trade between our selves as reasonable prices
understanding that a lot of what we do is sweat equity.

I played the graphics lunar lander on a PDP-9 with a graphics display
and push buttons (not the sw) in a back room in the Kiewit Computation
Center at Dartmouth in like 1972 or 1973, the same time I was playing it
in text on a teletype ASR-33 in Focal. Hand typed in and punched to
paper tape.

To all,
Some 20 years ago, I led the Computer History Museum's restoration of an
IBM 1620 Model 1 computer. Our team was successful in both bringing the
machine back to life and collecting a massive amount of manuals, books,
and software for the machine. Most notable the John Maniotes

It's thirty five cents, and they usually don't charge it until it actually
sells. Then they dock you another 13.25% on the total the

Eh, you get a lot of free listings these days. They take a huge chunk
though.

Man, I hadn't thought of Focal in years.
Never could beat that lunar lander someone wrote in it.

it's been there for over a week.
In unknown condition.
I think that price is disgustingly high.
I would love to have one but that is the down payment on a car, not a
used computer. Antique or not.

I will say the desktop chassis thing is kind of snazzy. But man be
prepared to replace a LOT of 7474 flip flops and 8 input NAND gates
(they seemed to use those as drivers. Weird, but worked but put the chip
under serious stress when old)

Aww! Looks like Mr. Mouse paid a visit. That will be fun to get running.

They're cute and all, but 15k? And it nice to have a spare for
troubleshooting the other one if needed)

Bingo! Thank you very much, I've read "2 Bit CAM" somewhere..but that

Either number might be a yyww date code, one of them probably is
Giggle offers numerous responses to 7536 IC and 8220 IC
Old enough they mght be in an IC cross reference book
