DFI G586IPC yours is similar to my'97 EZ-Trak.
I don't see anything special about that DFI board. It's a standard AT pentium motherboard. I'd imagine anything of that vintage with ISA slots will work. I'd hunt around some of the PC recyclers and see it you can find something similar for under $20.
Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!
Thanks for the info fellas! I just bought a used/working G586IPB/W7 for next to nothing. It looks like it will work to me. Do you guys think there is any reason it wouldn't work?

Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!
I'm not sure what a 7 Pentium is but it sounds like a later version of the Pentium processor. To replace the motherboard, you need an OLD pc board. 486, 586, or the earliest Pentium processor. The faster speeds of the newer processors will not work. You also need a VGA output for the monitor on the board. If the VGA output is from a plug in card, you will most likely need to load a driver for that card. Almost all of the early PC mother boards have a built in VGA output. I would do some more trouble shooting on the current board. Clean up all the connections and make sure the power supply has the 5v. If you manage to find an old pc, you may be able to replace the board but the easiest route is to install a backplane and use an advanteck board.
Also, some things about your post does not sound exactly correct. I have both a 1997 and a 1998 machine. The 1997 has a motherboard but has a battery and not a timer chip. The 1998 has the "CIB" using a backplane and half size single board computer and it does have the timer chip installed. What is the serial number of your mill? Not the control but stamped on the top front of the knee? That will give you the year of the mill.
Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!
Both the DFI G586IPC and the G586IPB/W7 appear very similar. Both are socket 7.
Maybe you should post a picture of exactly what you have. Generally if the board posts... but has a CMOS error you simply need to enter the BIOS, change the settings to reflect your hardware and save the settings. If the settings don't stick then you may need to replace the cmos battery. Machines of this vintage don't detect stuff automatically so you'll likely need to manually enter the drive parameters for example.

I have a spare backplane out of a TC-3 if you decide to go the advantech route. Send me a PM. ;)
Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!
I know this is an old thread but I just bought one of these old machines and I cannot get it to boot. Nothing shows on the screen. Blank
Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!
Blank screen: Bad CRT? Bad video board? Mother board dead? logic power supply dead?
Reboot and watch the floppy. It it lights up and spins a few seconds, it means the logic power supply is probably good and the mother board is thinking. Then I would look at cable and CRT. You did not say what type of MB you have. Some have a separate video board.
If floppy does not spin put a meter on the logic power supply.

George, thanks for the reply. Can you check out this thread I started? I have tried a different monitor and directly to the wall outlet. I'm not sure if I have a floppy LED or not.? But all the boards light up. https://www.cnczone.com/forums/bridg...ridegport.html

PCA-6743F-Q0A1E-ISA Half-size Single Board Computer, DM&P Vortex86DX, LVDS, LAN, 8 COM, CF PC/104 The only issue I ran into was I tried to replace the HDD with a DOM. I had a few 32MB DOMs laying around and tried to use them. Turns out they were to small and I returned to using the 8GB HDD and everything loaded fine and the old girl came back to life. I'm gonna replace the old CRT screen with a new LCD and she'll be good as new. And she literally looks almost like new. Got it from aTech school that rarely used it. Good luck with yours.

Excellent thread md63825. I replaced the SBC on my 1998 Bridgeport VMC - the old one had not died, but it had some weird glitches. Excellent result, I left all the defaults as they were - and the machine came up very nicely (the storage "disk" was all on the piggyback board, so I didn't need to even reload anything). Awesome, thanks again md. David
Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!
Sorry to resurrect an 8 year old thread everyone. I hadn't logged into here in a long time and felt I owed it to the forum members to post my fix on the machine. I replaced the motherboard with a remanufactured one and everything worked great. I don't know if/why the RTC and motherboard failed at the same time, but a new motherboard fixed it. The old girl is still making chips to this day. I hope someone finds this info helpful if they ever replace an RTC and their machine doesn't boot back up. Thanks again to everyone who helped with testing suggestions.
