Don't suppose anyone has a spare 4761 SDP card they'd sell for cheap

We've been trying to get this SSD-3500 up and running for use in an educational setting and any repairs we make is coming out of our own pocket. Originally thought the problem was just the snaphat battery on the CPU as it was no longer holding a charge but after replacing it, our machine is now stuck in an endless auto test loop. We plug it in and it powers up to auto test, checks all the keys on the keyboard and repeats until we unplug it. Have noticed on the 4761 SDP card that there are amber leds on and what looks like all of the red led lights. Looking through the service manual I didn't see anything specifically about the LED lights for the 4761 but I did see one of the symptoms of a bad 4761 is the machine won't start up. It mentions there is flash memory on this card that if corrupt will keep the machine from starting but it doesn't say anything about how to fix it. I pulled the hard drive and took a look at it but didn't really know what I was looking at but now we're leaning towards a bad 4761 card - hence the red led lights being on. Possibly when the snaphat battery went out it corrupted the flash memory ? We can't afford to be dumping money into this thing on a hope and a prayer it will work but was wondering if maybe someone has a spare known good 4761 card they might be interested in selling cheaply or maybe possibly trading for it - maybe a transducer for the card or ???? Better yet, tell us if it's possible to fix the flash memory without saved backup floppy's or MO's when we do not have access to the menu since it's on the endless auto test loop. Looks like we will be parting this out otherwise
