There is more in a VAX manual that I can't seem to find.
The Real Time Interface (RTI) is interesting. It
has 2 RS-232 serial
ports,
1 IEEE-488 port, and 24 bi-directional TTL level
I/O pins. These all exit
the machine on a 62-pin D shell connector. This was typically used as the
interface to the VAX when the Pro was used as a VAX console.
That does sound interesting. Especially given the GPIB -equipped
measuring equipment I regularly use. Would you know whether pinout and
other specifications are available somewhere?
