Well, we had to do it. A spare 40 Mb Everex mac SCSI hard drive was
connected to the external SCSI port on one of the cubes in the building,
and, lo and behold, disk recognized it and tried to format it. Read the
formatted-in disk info and all. Now you have a use for all those 80 Mb
A/UX hard drives littering the halls and the desks of America! 8}
Only the lack of hardware data on the drive (disktab, etc..) prevents it
from being used on a od only cube as secondary swap. This could be
interesting, because 20-30 ms 40 Mb SCSI drives are cheap, and the
performance of a cube with only an optical in it could be improved immensly.
My understanding is that you need a swap file on the boot device, and
a secondary swap file can be used wherever is convenient. By setting the
size of the first swap file to a unreasonably small value, the secondary
swap file is then used. I don't recall offhand whether 0.8 uses a hard-
coded size on the swapfile (it's in the 0.8 release notes, which are at
home right now) or whether support for secondary swap is installed yet.
This is almost as fun as the first few years I had my Apple 2!
