Hey Jason-- It's here, (Thank You Al) http://www.bitsavers.org/pdf/ti/terminal/silent_700/984025-9701rC_743_KSR_745_Portable_Maintenance_Manual_Jul78.pdf page 2-3, table 2-1 (pdf page 13). I think the terminal is normally supplied with a "loopback" plug (that's almost always missing) that goes into that DA15-M and loops the "printer/keyboard interface" to the "communications interface" when you are using the onboard acoustic coupler. If you want to talk to a local host not over the modem, then you remove that loopback plug and plug in your own cable that goes to your host. I made this cable with DA-15 female on one end and DE9-male on the other so that this terminal would look like a PC serial port and connect to various DCEs such as a terminal server and other stuff I have here wired for direct connect to a PC comm port, DA15-F DE9-M 1 5 GND 11 1 CD 12 2 RXD (to the terminal) 13 3 TXD (from the terminal) 15 4 DTR Keep on the lookout for a model 787 manual. This thing is cleaning up quite nicely and I hope to put the juice to it later today or tomorrow. It was found on the floor of a garage-- that would be the dirt floor. Not cool and it looked pretty rough on the outside but hoping it's still happy on the inside ;-) Chris -- Chris Elmquist
