[net.micro] Printer for TI-99A Computer

mitch@noscvax.UUCP (Ray Mitchell) (02/26/86)

I am interested in interfacing an Epson printer to a TI-99A
computer. I have the technical manual for the computer but
timing diagrams and address maps are not sufficient
to do the interface. I understand that the printer connects
to the computer I/O port and must somehow intelligently respond
to a poll from the computer before the computer knows a printer
is connected. I need a complete description of what I/O connector
signals are used and what type of protocol is used. I have
talked to TI on this but they refuse to release the information.
I would also like to know what type of keyboard keyin is required
to send something to the printer.

Any additional information on interface requirements for a disc,
the RS-232 interface, and the rest would be appreciated.
