Oh well, the aic driver is totally unmaintained these days.  You're
most welcome as a maintainer, of course. :)

Sounds rather unlikely to me.  Opcode 4 would be "Format unit".
Anyway, i don't know much about scanners either.

The NCR 810 controllers are indeed cheap yet as powerful as e.g. an
AHA2940 (minus the missing on-board BIOS and EEPROM for configuration
data).  I've recently bought one for DEM 80 (~ USD 50).  However, you
should make sure first that your scanner properly disconnects from the
bus.  Some cheap scanners don't, and that's one of the reasons why the
vendors ship them along with a separate adapter (which is meant to be
used solely with that scanner then).

Never trust an operating system you don't have sources for. ;-)
