COPY.COM for 8" disks

Ah...yes, that could be the problem.
My DJ-2D board is set for the standard E000H address.
I'll see what I can do. Thanks for the insight.

Yep, that did the trick. Works great.
Did a down and dirty disassemble, then in a hex editor I manually changed the 'CD xx F8' calls to 'CD xx E0', and used the disassembled code just for cross reference.
I then loaded it onto my SOL via serials, and saved it under CP/M.

Works like a charm (Although I haven't tried it on those IMSAI disks).
Much thanks.

I've attached the altered .COM file for DJ-2D cards at E000h.

I'm glad that worked. That program was apparently written by the gentleman who owned the IMSAI before me. He also made changes to the BIOS to add a 1024byte x 9 sector format to extend diskette capacity.

Just a quick follow up.
Seems this isn't copying all the data correctly. After a copy, the resultant disk books to CP/M with no issues, but many (all?) of the programs don't load and are somehow corrupt. Not sure why, but will try to find time to look into this further.
