Jeff,
I've been using the YAZE (Yet Another Z80 Emulator) emulator on my Linux
laptop.
I have a collection of compilers and can manage CP/M disk images images.
You may be
able to read/write the DISK-A.BIN file. I don't have time now but I'll
give it a try later.
YAZE runs on Unix, Linux, Oax OS X, Windows (with cygwin).

Hi Josh,
I figured it out. I was making it more difficult that it was. I
finally realized the boot ROM was looking for DISK-A.BIN even thought
the README txt file told me just that. I just copied that file to the
card & now it boots into CP/M. It appears that the only file in the
directory is WOW.COM. I realize the firmware/software components of
this project are still in development but what would be the easiest
method of adding files to the DISK-A.BIN image file? Sorry if the
questions are obvious but I am better with hardware side of things
versus the software side.
Regards,
Jeff

Hi Josh (& all that are interested),
I have finished the build of the JAIR 8080 board and I can get into
the monitor, test some RAM, ports, examine memory, etc. I have been
unable to boot CP/M however. I thinks that it must be the way I
prepared the SD card of the card that I am using. I have normally
used windiskimager to create disk images on SD cards. Windiskimager
typically uses .img image files to create a disk image on the card.
I tried using the .bin file as the source but the SD card doesn't
appear bootable so I assume I did something wrong. Also what size
cards are you using? Most of my cards are SDHC of 4,8 or 16gb
capacities. I do have a few 1gb standard SD cards that I can try also.
I have to admit that I was pretty excited to see your design come
to life. It is very cool indeed. Also I realize that you are
preparing for VCF-MW so it may have to wait but does any guide exist
for the monitor commands. I was able to figure out most of them but
I am not sure about the RAM test, unassemble, dump & SD card functions.
