Fantastic IBM 360/20 system found in an old building

You don't find many (really ANY) of these around anymore, especially in this apparent condition.

Consider a gofundme donation to help preserve some computing history. I have no financial interest.

There was a post about a month ago here about this system, as well as on the cctalk list.

A 360/40 or even a 360/30 might be worth restoration, but I'll demur on a model 20. Even a model 25 might be worthwhile, but the 20 bears no resemblance to the rest of the 360 line--halfword registers, stripped-down instruction set, and that godawful MFCM.

Of course, this is me; I've had the pleasure of working with a 20 as well as a 40. Very different animals.

You end up saving what is available and sometimes that is not the best of the series.

Yes; I suppose most of the S/360 series were leased and demolished at lease termination, particularly the larger systems. You used to see lots of ads in the back of CW for dealers of the used systems.

LCM has one. Some effort was spent trying to get it running.
I know of one in France as of 14 years ago.

I haven't looked at all the pictures, hopefully they have all of the ALDs

The 370/125 is of more interest. Hopefully they saved the microcode floppy(s)
