Although I still sell embedded versions of my Micro-C compiler commercially,m
the PC version (which is what the emulator is written in) is available free from
my web site: www.dunfield.com

One of these days I'll open it all up, and we could even compile it to run on the
H8 if anyone is interested (I have an 8080 code generator).

All in good time - there is still a fair bit of work to do before I want to release
it publically - I have not implemented the H19 yet, nor the disk controller. I also
need to integrate my 8080 debugger (I already have one written in my Altair simulator),
and clean up a number of little things and flesh out the user interface a fair bit.
I'll try to work on it on a regular basis and parhaps have something to show in a
week or two (I wrote the entire Altair simulator in the evenings during the christmas
break - so it shouldn't take too long).

If you want to get an idea of what it will be like, download my Altair simulator
from my Museum website ( http://www.parse.com/~ddunfield/museum/index.html )
The H8 simulator is going to be very similar, except that the front panel shown
will be an H8, it will have/run PAM8 at startup, and the terminal will be a heathkit
terminal instead of an ADM-3A.

It really won't be all that useful until I get the disk controller implemented, which
will probably take me a little while, since I don't currently have one or the docs
for it.

Perhaps eventually - my main goal is in simulating the machines I actually have
on hand, but since Ive already decided to add the disk, I may go one further and
add the Z80 - main problem is that doing so will change the debugger significantly
which I already have implemented.
