[TI-H] TI-92+ Connector question




I've been looking all over for an answer to this. On the top of my TI-92+
are two connectors. The one on the top left is the TI-GraphLink serial port
and I don't have questions about that. There's another one on the top right
and I can find no mention of it anywhere. I've opened up the TI-92+ and seen
a TTL octal driver chip real close with some kind of RC filtering, so I
suspect it's at least a byte wide port. Can anybody enlighten me?
