   Do the SCSI drivers work with the AHA controllers and the NEC CDR CD
   Rom Readers???

I've got an AHA1542B controller, and am using Julian's SCSI driver.  I
bought a NEC CDR-36, and was not able to get it to work with the
Adaptec controller, under 386BSD, or DOS.

Furthermore, when I called NEC tech support with some questions,
they gave me the impression that the '36 would probably have the same
SCIS disconnect problem I'd heard about for other NEC drives.  (The
short form of it is that the SCSI bus is unavailable while the drive
is seeking or doing error recovery or what not, so other SCSI devices,
like hard drives, are unavailable for maybe several tenths of a second
at a time.)

I took it back and got a Toshiba XM3401B drive instead.  The drive
seems to work fine so far, but the isofs code seems to lose on some
disks, like Prime Time Freeware.  (I haven't checked the latest
patchkit for any fixes to this.)
