[Questions re the IBM removable and a statement worrying about the number of
 read/writes]

First as to your worries re the number of read writes, I believe you have
nothing to worry about. My NeXT optical, which uses a similar technology,
has no problems in that area. As to access time and SCSI specs, here they
are:

Average seek time=66ms, Average latency=16.7ms, Disk transfer rate=4.35Mbs,
Synchronous data transfer rate= 4.0MB/sec, Asynchronous rate is 1.2MB/sec.
SCSI interface adheres to the ANSI X3.131-1986 SCSI standard.

As for the flopticals, they are still unavailable. This one can be ordered.
Education prices vary but are below $1000US. The unit also plays 3.5"
CD-ROM's.
