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.
