I've had a Bell Tech External Cartridge for about a year and was quite
disappointed with the performance (system hanging for seconds will tape
doing things, low throughput, etc).

Last Tuesday I picked up a box of odd's and ends at an auction which
happened to include a couple of Achive 499-R controllers (the new short
ones). Ah ha, I said to myself, wonder if this would cure my tape problems?

So I borrowed a friends Archive tape system and played with various combo's
for a few days (this is under SCO Xenix). 

The end result's:

	- short Archive controller needs Xenix 2.3
	- Bell Tech (Everex?) type controller will work with SCO if
	  drive is re-jumpered from #3 to #1
	- Archive controller will work fine with drive supplied by BTI
	  (Wangtek)
	- on the 20Mhz 386 I playing on there was no significant difference
	  in performance for the Archive or BTI controllers using SCO
	  Drivers

The bottom line - I'm continuing to use the Bell Tech Controller simply
because to use the Archive Controller would require using 50 pin ribbon
cable, or getting a special cable made to match the DB25 on their end with
the DB?? that Bell Tech uses. But when I get a tower I'll move the cartridge
inside and use the Archive 499R controller because it has a header and my
Bell Tech card doesn't.
