All,
I'm helping a friend sort out an unhappy Mighty VMC with the A2100 control system. The HD is working fine as it boots when installed in another computer. The problems is that I believe he pulled the CMOS battery out of both the WS and realtime boards to replace it while troubleshooting a dead encoder & axis drive. The drive and encoder are now fine, as is the WS board after we fixed the BIOS settings back to factory.
Having perused every thread I can find on the RT board subject, it appears that this was a bad idea and his RT BIOS needs to be re-set, if not reflashed.
I'd like to help him get this fixed. I have access to an old IBM-style keyboard, floppy (if needed to flash), monitor, video card (ISA and PCI available), and power supply. The problem is that I have no clue where to hook up the power supply on the RT board.
Any suggestions on how to power the board so I can see if it's just the BIOS settings or if it needs to be flashed? Having looked at every photo of RT boards on CNCZone, this appears to be a more modern version (no part # handy right now) as it has a CMOS socket and a PCI slot in addition to the 16-bit ISA slots and single 8-bit ISA slot.
Thanks much,
Ralph Christy
