AFAICR This was a Mac unit. There *MIGHT* have been an ISA card for it.
It *should* work with OS8 and OS9. I have the MIDI Timepiece II and I'm trying to get it to run on my 68000 Mac using OS 8.1. Clockworks boots but I need to load FreeMidi but it's bigger than a floppy.
Heck, it just might work with 7.5.5.
Here's the OS9 driver for it:

MOTU does not have a serial OSX driver for it.
You will need a 9VDC power adapter for it and a Mac 8 pin DIN serial cable "MacPlus" type.
Good luck!
