kidding aside does and amiga emulator exist for a sun, where you
could develop C-programs on a 40million-billion-hertz machine and then
port to our favorite?

Why don't you just pick up Commodore's new '030 card with memory?

It's a lot cheaper than a SUN.  Under the Amiga kernal it's faster too.

Folks at apple.com reply to our messages but we can't reply
there.  Here's some mail from and to "lsr@apple.com":

Not impressive?  Let's invert the comparison.  Can a 25 MHz Macintosh
emulate a 16 MHz Amiga?

And before you reply "why would one want to?" I can answer in three
easy steps:

AmigaVision
Disney Animation Studio
Deluxe-Paint III

I'm honestly not trying to start an argument.  As my .sig says,
I use both Macs and Amigas heavily on a daily basis, and I use them
for what each is best at.  Mac for DTP and word processing,
Amiga for video and animation applications.  If an Amiga emulator
was ever introduced for the Mac II, I would buy one as soon as I
could get to the store!  I sure snatched up A-Max as soon as I
could get it.

On the other hand, an Atari ST with Spectre GCR is 20% faster for a given
processor clock rate. Segmented memory (lack thereof!) is wonderful, ain't it?

That's a good point, still.... But pretty obvious too, right? People have
successfully emulated the Mac because *there's nothing to it*! The Mac is a
box of technological mediocrity. In the olden days ( }-) ) (a couple years
ago) before Apple caught on and clamped down, you didn't need any extra
hardware at all on an ST, just load a copy of Mac ROMs off a disk. It's
still hard to see what's so innovative about the software (it *must* be the
software, what is there to admire in the hardware??).

Or do people really think cutesiness == innovation ??

Yes, there are lots of emulators. But there's no *software* IBM-PC emulator.
My Amiga 3000 should have enough horsepower to run COMMAND.COM in a window.
Not as fast as a 386SX, but at least as fast as a PC/XT. I don't need it
enough to buy a bridge-board, but I'd pay some reasonable cash to do it if I
didn't have to reboot to run it (booting programs? Isn't that what you did
on small 360s?). Since Andy has decided not to support hosted MINIX on the
Amiga that'd let me have my UNIX-under-AmigaOS environment.

Well, there is an (software) IBM PC emulator (IBM.LZH, as it is
called) flowing around in the BBS's in the
San Diego, CA area...  It requires a copy of MS-DOS to boot and
doesn't multi-task, though.

This past Sunday, I spent the entire day hacking the Transformer 1.2 code to
try to get it working with the 68030 CPU - no dice.  At first I thought it
might be just timing problems - there is lots of CPU-dependant delay loops,
and NOP's used for delays.  I extended these to match the 68030 clock, but
there must be something else going on that I have overlooked.  Running with
or without cache & burst makes no difference - though I do have to reset the
machine once before the DOS screen comes up - perhaps the A2630 board is
turning the cache back on?  The system gurus after I press return and it reads
the IBM command.com disk for a bit - always a guru #8 at C01570!  I wish I
could see what was causing the problem!

I did manage to fix the keyboard routine, though.  Now my Cherry keyboard
responds to Transformer when run w/ a 68000, and appears to work OK in 68030
mode also.

BTW: There are some bogus versions of Transformer labelled 2.2 going around.
I used Arp's CMP command on these using the original 1.2 Xfrmr, and the only
changes made are in the revision numbers!  Don't bother getting 'em!
