IBM also had an XT 370 that used the PC 370-P, PC
370-M, and
PC 3277-EM cards.
The P card emulates the 370 instruction set. This card has the
Motorola 68K cpu's. It also has the 8087.
The M card is the 512K mentioned above.
And the 3277 card hooks up to the S/370 mainframe.
So I reckon you have the XT 370.
The price of the 370 attachments was $3,000 over the price of the
XT this stuff had to go into. Jeez!
Compared to to a real 370, a console, terminals, DASDs, and what not,
this price is not too bad. Add the fact that the XT 370 likely did
not require a riser floor, motor-generator, air conditioning, and a
square kilofoot of floor space, and it starts to look even better.
I wonder why they were not more popular. Run JCL on your desktop machine!
This may have a strange appeal to me, but how many people really want to
run MVS on a desktop machine? I'd really be interested in knowing what
people used these machines for other than super-3278s.
Anyone know what happened to OpenMVS? (Feels like Unix, works like MVS)
IBM was pushing it in some Unix rags a few years ago.
