[aclug-L] Re: SCSI card

[Tyler Doubrava <tdoubrav@xxxxxxxx>]

I've got a BT-948 (Mylex) in my computer, and a Yamaha CD-RW.  Both were highly
recommended to me, and I haven't had a bit of trouble from either.  

Mylex's have a good design for high-volume throughput, too.  If you browse the
SCSI howto, it describes Mylex's "mailbox" style SCSI bus.  That lets the
computer go about its work while a read/write command is sent to the SCSI
device.  Cheaper cards may not have this logic, and the computer can't do
anything until the command finishes.

I got mine for about $50 on the web.
