Assuming your info is correct and that you really have bubble, Algirdas is pretty much right. "moving arround is not a reason for memory card to die." I would try to reseat the board and check connections. Real bubble memory is like flash memory's predecessor in that it didn't require a battery backup.
Therefore there would be no reason to lose anything when moving the machine. We used to get machines in from Japan that had been shipped and put in storage for long periods, and when powered up would have everything including the programs still intact after long periods of time.
If your bubble was replaced with CMOS, you could lose your memory when the battery dies and you would need to re install the software from the original disks. Your memory card will have a battery pack mounted on it if this is the case.
By the way, which control do you have on the machine? By your description I would say 5000L or 5020L-G since they used bubble.
