- * special driver for MUSTEK flatbed scanners MFS 06000CX and MFS 12000CX
- * these scanners come with their own scsi card, containing an NCR53C400
- * SCSI controller chip. I'm in the progress of writing a driver for this
- * card to work under NetBSD-current. I've hooked it up to a Seagate ST01
- * hostadapter in the meantime, giving 350KB/sec for higher resolutions!
- *
- * I tried to connect it to my Adaptec 1542B, but with no success. It seems,
- * it does not like synchronous negotiation between Hostadapter and other
- * targets, but I could not turn this off for the 1542B.
- *
- * There is also an other reason why you would not like to connect it to your
- * favourite SCSI host adapter: The Mustek DOES NOT DISCONNECT. It will block
- * other traffic from the bus while a transfer is active.
