When you talk about open your mouths......You should open your eyes.... and
read the whole message.

I said, You would have to remove the SCSI drive and put it in an External
Case and use an APPLE II SCSI CARD.

If your going to BASH me, quote the whole post...... and you'll see
yourself, that you are wrong.  I never intended to say that the MAC 20
drive would work in its original configuration, only that the HARD DRIVE
ITSELF would work connected to the apple HIGH SPEED SCSI interface inside a
normal SCSI case. NOT THE ORIGINAL CASE.
