Make that definitely...

I found my PinPoint Point-to-Point manual - it has 8 different serial
card drivers. #6 is "STANDARD.6850" which is compatible with:

AST Multi-I/O Card
Prometheus VersaCard serial option
CCS Model 7710A card
SSM AIO serial option
SSM ASIO Apple Serial I/O Interface
ALS Dispatcher

It looks like the AIO card did not have a serial port as a standard
feature.
