  If you're running DOS it is. If you're running UNIX, probably not. The
reason is that most 1:1 controllers work with a combination of hardware
and firmware in the controller ROM. Therefore, UNIX, which doesn't use
the firmware, does not benefit.

  There is an RLL version which is a lot more money and appears to be
nothing but a hand selected 4096. Most 4096's will run RLL okay (I'm
running some) but it's not guaranteed. If you're trying to save a few
bucks I'd try it. At 4096 prices you can probably sell one 4096 at a
loss, buy another, and still be hundreds ahead of the price for the RLL
version.

Disclamer: I said it's not guaranteed.
