- In theory it is perfectly possible to have two hosts on the same
- SCSI bus and use the same drive(s), _if_ the operating system(s)
- in question can cope with that (and a bunch of ifs about hardware,
- e.g., some controllers may not like each other).
-
- As for the Mac PowerBook 160/180 is concerned, if it detects the disk
- adapter cable is connected at turn-on, it begins to behave like a
- disk, disabling the keyboard &c -- only power switch will work.
- So you can't run any programs in it while it's connected that way.
-
- As far as memory-to-memory moves are concerned, of course SCSI bus
- could be used as a general-purpose information channel, but whether
- it can be done with any existing software/hardware combination,
- I don't know. With the Macs certainly not.
