In the early 80's, keyboards on 'lower-end' computers left many users wanting improvement. The TI-99/4A did not have the worst keyboard out there, but there was still room for improvement. One company of the era took up the challenge, but I'm sorry to say, it missed the mark a little...

The Rave keyboard was an improvement of sorts, but the technology of the time was larger, requiring that the user remove the TI's keyboard. The connector on the Rave keyboard also stuck up like a sore thumb, and in my opinion, ruined the TI's sleek looking appearance.
A few years back, one of the TI-Gods known as "Tursi" designed a neat little keyboard adapter that was small enough to fit inside the TI... with the keyboard! If that's not enough, you even have the flexibility of mounting your connector anywhere you want. If you would like to read more about this device on Tursi's website, go

After you install the device, your TI will pretty much look the same, with the exception of the connector. I mounted mine on the left-hand side near the rear of the computer as seen in this photo below.

I've made up a couple of PS/2 keyboard overlays, available for download in the attachment below. These two photos will give you an idea of what they look like in use.

This turned out to be one of the nicest upgrades ever, which was a little unexpected, but after I started using it, it all made sense. You see, the TI console is not the easiest to move around or into a good position, with the 'fire hose', monitor cable and power cables ALL hanging off the unit. The PS/2 keyboard uses one little cable and can easily be moved around, and after all these years, most of us are used to PC keyboards.
This is an upgrade/modification that I recommend to anyone who is not a purist that requires a stock system. After all these decades, the TI is still evolving and improving.
