Erik,
I, too, was surprised by the Amax's video performance. I
called Readysoft and they told me that without a 24 bit video card,
my benchmarks were in line. I was able to improve performance
significantly by changing to a "standard" 640 x 400 non-overscanned
hires laced screen and by increasing the refresh timeout. Benchmark
was about .70 of a Mac II. I believe Emplant benchmarked about equal
to a Mac II. Only drawback is that the timeout causes jerkier
scrolling, but is tolerable. I also was able to install System 7
Pro, which wouldn't work on Amax II, but works fine with IV, although
it is a bit more cumbersome than 7.1 and doesn't really add much
additional functionality unless you are networked and need
Applescript.
SCSI stuff works like a champ. I have both a tape drive and
CD-ROM drive and both were easily recognized as scsi manager
devices. On the downside, Amax IV no longer reads and writes 800k
Mac disks. It only reads/writes high density disks unless the 800k
disk is a 720k IBM format. They have an Amiga utility which will
read/write the 800k disk into an Amiga file device, sort of like the
Janus JLINK device. This file device shows up on the Mac desktop as
though it were a true disk, so in that respect you don't lose the
function, but it is now less convenient, especially for loading
software which was distributed on the 800k disks.
Multi-tasking is good. It works well along with the bridgeboard. I
think Amax IV is a good product except for the limitations on video
and the awkwardness of using 800k Mac disks. However, that isn't a
lot different from Emplant, which also didn't read/write 800k disks
unless you had Sybil, which never seemed to work too well for those
that had it.
