- The standard serial I/O ports for 4D/60's and other machines besides
- Indigos either use UART's and incapable of using external clocks or do
- not have a signal connected to the stupid DB-9 connector.
-
- There is a sync board used with the IBM and x.25 products, but
- you wouldn't want to buy it just for MIDI.
-
- The Indigo can talk to MIDI devices on its din-8 connectors.
