Hi everyone,

Just a quick update. With help from Josh I found a bad IC on my board. Made the replacement and now the SD card is working!!!

Now I need to understand how to use the SD card with CP/M. This is new to me. Are there any docs on how to transfer programs to the SD card?

Again, thanks Josh!

Hi Harold,
I saw Josh's reply to you in which he has a link the latest firmware and CP/M image on the Wiki page for the board. I just wanted to share that I was initially confused on how to use the CP/M disk image with the SD card. I kept thinking that I had to use an imaging program like Windisk imager to create a usable disk but I reread the documentation and realized that all I had to do was copy the disk image file to the formatted SD card as Disk-A.bin. When you bring up the system It will find that image and present you with the option to boot CP/M. For all intents & purposes it looks just like a SSSD 8" diskette that is the original CP/M interchange format. I then followed Josh's instructions on how to use the monitor program's XMODEM command to transfer some additional files like MBASIC.COM and it worked as advertised.
Regards,
Jeff
