- Both of those imply standard SCSI-2 eight bit transfers, the latter being Fast
- Synchronous.

- The SCSI specs, as given, are basically the same as for the C= board. We'll
- have to see how they differ in practice. The C= board doesn't have DRAM
- on it.

- You'll always have to run some ISO-compatible filesystem to read CD-ROM/CDTV
- disks -- they aren't written in Amiga FFS or OFS, which is all your system ROM
- knows about. If these folks are including one of these with their board,
- that's certainly a good thing but no great bit of magic. I think other CDTV
- features depend more on the CDROM drive than the SCSI interface.
