Re: CP/M HEX file question
- Multiple options can be useful.
My XMODEM source is on one of SSSD soft-sectored 8-inch diskettes I want
to transfer. My version was configured for BYE and a PMMI. Newer
versions of XMODEM probably support YMODEM and ZMODEM.
My Modem 7.12 is handy, but the next generation MDM might be better. I
think my MEX is configured for Vector Graphic, but could be configured
for an Altair.
There is still old software to recover and new code to write. Nothing I
have works on CDOS. Altair KERMIT is handy to have too.

that makes it pretty easy for you to change the I/O drivers for whatever
peculiar hardware you might have. While I was at it, I implemented the
CRC mode, because the CRC calculation code is interesting.

It was then a small matter :-) of converting from Z80 code to 8080 code,
and then rewriting the OS interface, to make a CP/M version.
