Re: New S-100 8086 Board Done, CPM86+ Done.

[Brian Marstella <br...@marstella.net>]

Thanks, John!

The write-ups are easy enough to follow, although I'm looking forward
to eventually getting the real hardware. The code seems well-
documented as does the board. Having such a complete monitor will be
of tremendous use.

Thanks to you, Andrew, and everyone else involved in getting this
board ready.
