There's not really any such thing as a non-SCSI CD-ROM drive. ATAPI is really
just SCSI transported over an ATA (IDE) bus. So, yes. It'll work (should
work) with SCSI, ATAPI, parallel port, USB and Firewire drives. What it won't
do currently on Mac OS X is work with non-writeable drives - 'cos the OS X
kernel won't let you send SCSI commands to such devices.
In theory, the SCSI support should work with OS X as is, but there are
problems scanning for devices (as you and others have reported). I'm trying
to source a SCSI writer for my Mac because it doesn't seem to want to work
with ATAPI devices. They work fine under Linux with this machine, but OS X
can't seem them for some reason. I think this may be due to crap drivers for
my ATA card in OS X.

People do. ;-)

I don't know if the dfference will be great in full-screen mode, but it'll
certainly make windowed mode a lot faster in OS X.

Never used Applescript, so I don't know much about it. It's based on
Hypercard/Metatalk isn't it? I don't know how an application exports an
interface to Applescript. Worth finding out about . . .

That would be interesting to see.

Don't hold your breath. ;-)

It won't require the JIT, but it will use the JIT's memory allocator (or at
least a modified version of it). This basic idea would be for the
PowerUp/WarpUp emulation to create PowerUp/WarpUp tasks as native tasks on
the host. The easiest way this could work would be if these tasks could share
the same address space as the UAE virtual machine - i.e. a direct, flat
address space like the JIT uses - but with no offset. That is, the
PowerUp/WarpUp tasks would access memory at the same addresses as they would
on a real Amiga.

A PowerMac 9500. Long in the tooth, but not a bad machine. It's been beefed up
with a 333 MHz G3 card, an ATA/66 controller, a Rage128 and a whack of RAM.
It runs Linux well, but OS X is dog slow. To build the OS X version of UAE, I
access the box from a remote shell (it's way faster than the OS X terminal
emulation).
I do have some even cruddier Macs. The Internet gateway, file/print server,
etc for my home network is a StarMax 3000 running Linux. I stuck in a G3
card, whipped out all the fans, and it's totally silent (and still barely
gets warm). And I have an all-in-one 5500, which my daughter now uses. OS 9
might be rubbish as a real operating system, but it's great for
3-year-old. ;-)

That would require support for sound mixing. Once AHI support is done, doing
this should be easy.

I thought they might say something like that. ;-)
