Hey Will and Jeff,
There's no mistake - this is a different rom on the card which will
not take the 208 mac rom - I've tried it and it fails every time at 65536
(hex 10000). The failure is not just in the rom it is in the flash
utility which doesn't have the logic to recognise a 128k chip from a 64k
chip and the chip numbers are not reliable to spec so id becomes try it
and see. Though the flasher saves the pc7k rom as 128k and astoundingly
flashes it back in as a 128k rom recording 130 odd thousand bytes
verified with the card working fine in a pc and none the worse for wear
it will not take the 128k mac rom. None of the modded roms will work -
none of the two stage flashes will work and none of the one stage flashes
will work - live boot or secondary device. Soldering a replacement is
pretty difficult given the size of the chip and the unreliability of chip
numbers and possibly beyond the worth of the effort. The twist may be
that the pc rom is less than 64k so why is the mac rom more than double
that? If the pc rom is saved at 128k it consumes around 120k of hex
compared to the mac 208's 124k of hex as extracted from the 208 updater
but we don't know how much of that code is redundant. So if anyone would
care to put a mac flashed card in a pc and save the mac rom from a
flashed card at 64k I will try it on a pc 64k Sapphire. The save may be a
blind dos operation - as a mac card will not produce any kind of screen
on a pc - with no display but the card should come to no harm.
Another explanation is that maybe half the rom is no longer
writeable or locked - unlikely though.....interesting little
problem.....and I was just about to try the 9000+ series...
