Hello all! I have an old Omni IIe controller and the network interface has stopped working. I have tried clearing the eeprom and clearing the ram, neither helped. I have just recently upgraded to 4.0b firmware. The serial ports work and that is how I have been configuring it.
So, it has been years since I connected to the network on this controller. My computer has been updated (now Windows 10) and the network is busier. However, I tried connecting a laptop to the controller with a crossover cable and the laptop set to 10M half duplex and get the same behavior.
1. Is there a repair service I can get on this board? I know I can buy a new one, but that is $700...
2. Is there a power supply that is prone to failure that can cause the network to stop but the board will otherwise continue to operate?
3. Is there another failure point on the board that can be replaced, ie a chip or transformer? I have the equipment to do surface mount repair, even the QFPs.
Thanks in advance.
