Who knows - think of short circuits... All the other 74 logic, z80 chips

bPROMs (who knows...) to restore the backup - I could replace it with
other (EP)ROM stuff more or less easily - but w/o the contents... you get
the picture? ;)

But right now I just care about backing up all
EPROMs and PROMs from this
system here just in case something happens... (and the 6306's are now
backed up as well :-)
Do fusible-link PROMs go bad? At least do they go bad any more often
than some of the LSI on that board?
