Texas Instruments Calculator Parallel Port Link

My link cable for the parallel printer port and software

schematic

Please pay attention to the pin numbering of the printer port connector.

I put one plug of the TI­to­TI link cable in an insulating tubing. The insulating tubing is pierced by three wires. The tubing is very tight – I warmed it with a candle. Some 2.5 mm stereo connectors have bad contact in the socket of the pocket calculator. So look carefully at the original TI jack before buying one.

It is important to initialize the printer port before connecting with the TI (just start the link program on the PC). Otherwise the TI will slow down (you cannot enter anything).

If you use link85xp.exe, the second important thing is, that you have to rename *.85p and *.85s files to *.85g. Do not rename backup files. (As the original link85x, link85xp supports backup files *.85b and grouped files *.85g only.)
