MOTU MIDI Express PC with Mac

[teroyk]

I found very strange thing from MOTU MIDI Express PC, it's PC ISA-card has rack-I/O-port and Mac serial port, but not for connecting MOTU Mac devices, it is for connecting Mac 
Idea might be that you can make PC as slave for Mac midi program. I only find badly scanned pdf manual that missing those pages about that. DOS connection-setup program started without card and shows little mac-icon as B-port Maybe someday I test with real setup.

MOTU continued to support multi-computer setups through the last of their serial port interfaces. i have two MTP-AV USBs with USB + serial ports on them, I can connect a computer to both devices and I get a 17th midi port that I can send data back and forth between the computers with. Clockworks on Mac actually shows it as "2nd Computer" and you can set up a completely different routing matrix between the second computer and your midi devices.
