I think we're rather missing each other's points here. There's nothing at
all 'wrong' with using an emulator as an aid to writing software or
whatever to run on a classic computer. I know plenty of people who've used
the PDP11 emulator to do just that. And I used one of the PDP8 emulators
to try things on when I was rebuilding some bits of my 8/e.

But too many people (not on this list, thankfully :-)) seem to regard the
emualtor as a _replacement_ for preserving the hardware. This is what I
commenting on...

On the ground that I have the world's slowest PC, I suspect my CoCo 3
would in fact be faster than the emulator. Add an 6809 In-circuit emulator
(no, I don't have one yet, but I'm looking...) and I _know_ it would be

Give me one good reason why not? It should be _trivial_ to use a 5380 or
something like it to make a SCSI cartridge for the CoCo. Add an OS-9
device driver and you should be able to burn CDs....
