No the RAM is well and truely soldered in, also I have no control over the OS, all I do is stick the disk in and power up, all diagnostic is done by the code writer (circa 1991). I'm trying to find the diagnostic info but it is not easy come by.
I have already replaced the MCU (68000) and exchanged a number of chips, those in sockets. As you can see, all I can do is keep swapping parts until it works unless there is a better way!? I did have a spare fully working system to swap parts with, damn and double drat that is now dead too
