SUMMARY
Micro Channel Architecture (MCA) computers are not compatible with the Microsoft bus mouse.

The Microsoft bus mouse is not designed to be installed in a MCA machine. The inport card is too large to fit in the expansion slot.

All IBM PS/2 Model 50s and higher are MCA machines. Other companies manufacturing MCA machines include NEC, AT&T, CBM, and NCR.

NOTE: The IBM PS/2 Model 30 and PS/1 computers are ISA machines and do support the Microsoft bus mouse.
