DTR Tech Posted February 10, 2011 Report Share Posted February 10, 2011 I have successfully created and used a main control unit replacement for the 330/340 model machine. I have about 5 of them in machines right now and have been for the past year. It is based on the HP DC7700 PC to replace the Toshiba unit in the Frontier machines. I have designed and manufactured a PCB to replace the “Timer” board in the current units. Attached is a write up I did with some images. I have also created a different OS load disk with a bit of effort. This makes replacing these much cheaper. Quote Link to comment Share on other sites More sharing options...
