Mac IIci startup Sad Mac error code 0000000F, 00007FFF

Per http://www.gla.ac.uk/~gwm1h/Error_Codes/Sad_Mac_Codes.htmlthis is a "$000F Reserved for Macintosh compatibility" issue.

Any ideas what could be causing this? Have a stock standard Mac IIci, 12mb with 80MB hdd and ext Cd 300e attachedand terminated properly.

Have noted the occasional lockup when transferring or mounting large (disk image) files.

Any ideas welcome.

hi @TimHD - i know it's been a few years but curious if you ever got to the bottom of this error code since i'm seeing something similar now...

Wild guess—I'd look to either the disc or the System file on the disc. 64 is, I believe, "couldn't read System file": at a wild guess that higher numbers are later in the boot sequence, it might be try worth seeing if your System has got garbled.

Bingo -- the system file was the culprit!

thank you, @cheesestraws
