Darn. My hopes are shattered. Lots of Verilog in my future, that is if we can find 360/50
ALDs...

Thanks for the detailed answer. I see the front panels look remarkably similar though.
Short of redoing a 360/50 on an FPGA (I'd need to retire to have enough time for this
one!), could I use the /50 panel with the /65 emulator?
Not really! The 360/50 had
4 "rollers" for 4 rows of lights, and one row of data switches, and 2 rows of
dedicated lights.
The 360/65 had 6 rollers with 6 rows of lights, plus TWO rows of data switches, and
pretty much no dedicated lights other than associated with the rollers.
Both had a row of address switches under the data switches.
So, yes, in GENERAL, they had a similar look and layout, but in detail, there was a lot
different, some of it specifically related to the memory word width.
The only machine that looked really different was the 360/30, that had a panel more
reminiscent of the 1401.
And, of course, the 360/85, which was really a prototype of the 370/165. As far as
software was concerned, it was just a really fast 360, but the hardware was MUCH more
advanced.
