Instruction for using the CoCo Diagnostics Cartridge with the Dragon 32.

SD image for Pocket BMC64 with 2 start.elf and sample files.

I found that I had two different board that needed different versions of the start.elf.

If your device wont boot rename start.elf to start_new.elf and the start_orig to start.elf.

If it still doesn’t boot send me a photo of the board and I will try to source a working alternative.
