[Coco] Emulators on a laptop?

If you're trying to run one of Jeff's 16-bit-coded emulators, I think
they might require DOS mode to fully function. I've seen his source
code and I doubt that he will bring these up to date to the modern 32
or 64-bit Windows standard anytime soon.
You're better off moving to the M.E.S.S. emulator since the video
window and CoCo accuracy is much better. You're not going to get
visual depictions of the cassette recorder, MPI, or floppy drives (at
this time), but you can join the list of people who push and bug the
dev team to improve on some of these bells and whistles.
You can run M.E.S.S. from a Windows console prompt (closest thing to
an MS-DOS prompt), or do everything from their "front-end" GUI using
your mouse for most functions. You can get it configured to where it
requires no keyboard interaction until you get into the CoCo
emulation window itself, where the OK prompt sits and waits as usual.
I've run M.E.S.S. on a Pentium 4 laptop for over a year, and have
moved over to a dual-core Pentium laptop running Vista and everything
seems to work fine. M.E.S.S. is getting power hungry so you'll have
to keep up with the requirements by getting a decent
computer. Personally, I think M.E.S.S. is suffering from a major
design flaw if I am right that it concurrently maintains certain
running features of all the supported emulation modes. I hope this
is not the case.
Anyway, to see it running so many computers from a window is an
awesome sight. You can literally "have it all" that you couldn't
have as a kid! Not only that but my Rainbow IDE supports writing
software for a great number of the M.E.S.S. emulated computers, where
your source code is compiled and mounted in/on those computers in one
click. Up pops the CoCo, or another computer, and you can run your
program. If it's a cartridge build, it runs automatically like a ROM
Pak. If it's a floppy disk, type DIR and there's your stuff. I'm
working right now on OS-9 builds using RMA/Rlink/Asm FROM THE IDE,
and your final program(s) will end up on a virtual OS-9 floppy disk
and mounted in OS-9 or NitrOS-9 in the pop-up CoCo window. There's
no way to describe the seamless builds from source code to emulation
unless you try it and see for yourself.
