Roland MPU-IPC (1984) mpu for IBM-PC, XT, AT
« on: October 30, 2016, 07:30:51 AM »

this is the MPU-IPC, similar to but not to be confused with the revised MPU-IPC-T
http://lajko-hangszer.hu/midi-RolandMPU-IPCmanual.pdf
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, 5160 , 5170)
