This card will not flash by any method - flashrom is perhaps not
reporting the size of the rom correctly - nor is it perhaps reporting the
128k flash write correctly. Maybe the change is a move by manufs to stop
the flashing - maybe just a cost cutter or a mistake - but it stops the
flashing to mac dead in it's tracks. The chip may be a 64k or 128k - but
only 64k is writeable with the mac rom.
The pc rom active code is actually smaller than 64k but written as
twice x 64k by flashrom save when saved at 128k - yet written back to the
card as 130 odd thousand bytes verified - very strange. The pc rom can
also be saved as 64k and written back to the chip as 65536 bytes
verified. The 208 mac rom is around 124k padded out to 128 to fit a 128k
rom chip but I think most of this code is redundant and it could be
reduced to less than 64k given the knowhow. But the rom is written in
Forth fcode and practically impossible to edit.
Soldering a 128k rom chip in place of the 64k may be a solution if
the size of the chip is the only change - but the chip is quite small for
soldering - pity it's not in a pullable socket.
