I've never heard of that one. Who puts that one out? I would like to kick the tires on that one. As for the "HALT" instruction, it does seem a logical way to write a software emulation of the BIOS. As for how MS-DOS picks it up, curious how that would work.

You might want to try either Emerald MicroWare (whose address I could go and snag) if anyone wants it) or any type of controller that plugs into the Z80 slot. Most of these controllers come with software that will talk to the hard disk no matter what kind of machine it's running on. I've seen such a setup which even comes with source code for its BIOS so it's possible for me to get a system like this for my Ampro (for which I have source for its BIOS _AND_ main ROM) such that the entire BIOS which will talk to both hard and floppy disks is entirely self-contained, and can even boot from the hard disk and not have to boot only from the floppy and manually (or semiautomatically) run a hard drive initialization program (not format, but put routines up so the system can talk to the hard drive). > Other thing...

I know this part of the message belongs elsewhere, but I thought I'd ask this: Will it be available in the US? If so, that could finally put purely UNIX machines in the hands of commoners. Then I could gloat as my pro-MESSY-DOS friends are dumbfounded of what it could do.
