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. Thanks, Ray Mitchell NOSC code 911 :w
