I have been successful in copying the EEPROM files from a machine that I had the System discs for onto my old 9100 that did not have the system any more. The System disks now will boot the old 9100 and I assume in half an hour I'll be able to copy them onto the base and then be able to again boot the old 9100 from the hard drive. Next to see if the programmers files are still there, then to see if there is any way to extract files through the RS-232 port... I shall put a file on the archive server with the EEPROM and the corresponding System discs.
