	I've heard of people mention an "Adaptec SCSI to ST 506" adapter or

	information please let me knnow where I can find this adapter.  I saw
	a few in computer shopper but some had a ST506/407 on the end of the
	name so I don't know which one to get.  Will I be able to hook both of

The Adaptec 4000-series of SCSI-to-ST506 adapters is what you're seeking.
The 4000A adapts one or two ST506 drives (e.g. your ST251) to a SCSI bus, and
the 4070 adapts one or two "2,7 RLL" rated drives (such as an ST277R) to a
SCSI bus.

Before my ST251 drives went belly-up due to stiction, they were operating
just nicely using a 4000A on the Amiga's SCSI bus.  The largest drives I
tried with the 4000A were the Maxtor XT2140 and XT2190 and they, too, worked
fine on the Amiga SCSI bus.

Since all my drives are now embedded-SCSI, I have several 4000A cards for
which I have no further use.  The cards bolt right onto the back of every
"ST506" drive I've ever seen, so installation is quite simple assuming you
have a reasonably-sized HD box.

If you're still interested, send email and perhaps we can work out a deal on a
4000A.  If you want to buy a brand-new 4000A, you'll have to contact Weird
Stuff Warehouse in Milpitas, CA (on Sycamore Drive; sorry, no phone number
handy; call 408/555-1212 and ask for their number).
