I recently received mine and also am having issues. On cold boot the BigRAM 2630 is not recognized. A reset and memory works fine but the floppy drives subsystem internal and external no longer work. All disks show as NDOS and give seek errors if I attempt to reset. The floppys work on cold boot but as soon as BigRam is recognized failure. I have stripped machine to bare minimum to no success to get Bigram to work and have functioning floppies.
Anyone else see symptoms like this?
