Outstanding!  Then I can make it work with little gambled.

That's a real bummer about none of the scsi stuff working on your machine.
I still suspect that it _may_ work on mine because of the different
internals and because of Jerry's experience, but so long as I can designate
one of the partitions of the new ATA HD to startup with system 9.x, at worst
it's only an inconvenience and not a deal killer.

What's a 100 gig ATA drive run now-a-days ... about a hundred bucks?
Jheesh, I can recall spending 4-500 for a giant, it seemed at the time, 40
meg ... the only hard drive I ever had to mechanically fail.

BTW, sorry but I forgot to answer your question about "tweaking" the bus
speed on your mother board.  At least I think it was yours.  This list is
busy enough so it's hard to keep it straight.  Rather than trying to give
you all the details on something I've only read about, I'll point you toward
a source.

At that site, you can find detailed instruction about how to rearrange a few
jumpers so-as to increase the bus speed on the mother board, but here's my
general understanding.

You wouldn't want to consider this for a machine that is in warranty because
it voids it, but for those of our vintage perhaps a bit of playing around is
worth is.  Also, whether it works reliably is a matter of luck.  Your board
is certified for the speed at which it's set, but can run reliably at some
higher speed.  How much higher is set by the weakest component on the board
and you can't know until you try it.  If you over-clock the board,
reliability problems occur including extra crashes.  My understanding is
that smoke and fire are not considerations and that you can revert to
original settings if desired.

Reason to consider this - layman's explanation:  the actual speed you
experience is a result of both the processor _and_ bus speeds, the first
being a multiple of the second.  If the multiple is too high, then the
processer may be ready to hand off information before the motherboard can
accept it.  The higher the multiplier, the more often this happens and the
less benefit the you get from your fast CPU.

Our machines - the early G3s - came with a multiplier of 3.5 to 5.0, the 5.0
being for the 333mhz machines.  The constraint of the motherboard bus is why
the 333mhz machines were not, as might have expected, the full 43% faster
than the 233mhz units.  It's sort of like putting a really hot engine in a
car but keeping the original tires.  Now it could be that the original tires
were more than the car needed with the little engine, so the bigger engine
really increases performance.  Or, it could be that the tires and original
engine were balanced, in which case the big engine is more of a noise maker
than a go maker.  Only the Shadow knows where the balance lies, and he works
for Apple and doesn't talk much.

Tim Taylor would suggest that you do it.  I'd just request that yuou report
back if you decide to try it.
