this is the MPU-IPC, similar to but not to be confused with the revised MPU-IPC-T

hardcoded resources: on  i/o port: 330 interupt: 2/9
as u can see the irq switches on the mpu-ipc-t card are not present here!

earlier version of the mpu-ipc-t which has 4 Midi ports (1in, 2 out, 1 sync out)
some comments on wikipedia claims this interface can be problematic using it on machines faster than a 286 (AT style machines) but the box packaging claims its compatible with all PC, XT, AT style IBM compatibles (5150 (https://en.wikipedia.org/wiki/IBM_Personal_Computer), 5160  (https://en.wikipedia.org/wiki/IBM_Personal_Computer_XT), 5170 (https://en.wikipedia.org/wiki/IBM_Personal_Computer/AT))
