Kchula-Rrit Posted February 7 Share Posted February 7 (edited) My console has a "JediMatt" USB keyboard adapter that I bought from (I think) arcadeshopper. The adapter does not recognize the keys F and U (both upper and lower case), +, =, or the left-shift key. The right-shift key works as expected. Anyone have this problem? K-R.

+arcadeshopper Posted February 7 Share Posted February 7 Sounds like a wiring issue.. the fact that it's specific lines makes me think a common one from f u and those but there's no common so maybe a couple wires aren't connected? do you have photos of how you installed it? did you use my cable or make your own? 2 1 Quote Link to comment Share on other sites More sharing options...
Kchula-Rrit Posted February 8 Author Share Posted February 8 arcadeshopper, thanks for the schematic! I made my own cable when I installed the adapter and just plugged the lines in until the key-codes worked. After checking Thierry Nouspikel's Web pages I didn't find any common cause for the failure. No common CRU pins, etc. The keyboard that had the problem was the one I used when I installed the USB adapter. It's a Logitech K360 radio keyboard. I installed the adapter where coffee-boiler power supply used to be, then plugged the tiny transmitter plug into the keyboard adapter, so I didn't have to cut any more holes in the case. Anyway, I swapped the radio keyboard for an old cabled one and the adapter reads all keys from it! That's a shame, I really liked that Logitech! K-R. 1 Quote Link to comment Share on other sites More sharing options...
Bill R Sullivan Posted February 9 Share Posted February 9 (edited) Sorry, I wasn't able to reply sooner; but health issues come first. Anyway, I have two TI-99/4A units that have this same USB and F18A VGA, along with a 4 port KVM (VGA/USB) that I can use with 5 Logitech keyboards. Two that I like the best for the TI, also work well with two Win 7 Pro mini towers and a Del Docking station for my two Dell Laptops (E6430 & E6420). Absolutely great, until a TI has a serious keyboard issue that requires it to be replaced! Have a great time with your system! RetroBill P. S. Actually only one is a Mini tower and the other is a Mid tower. Edited February 9 by Bill R Sullivan 2 1 Quote Link to comment Share on other sites More sharing options...
