I'm planning a project to recreate the history of Chuck's rz and sz programs (which includes minirb, etc.) on github.

The original X/Y/ZMODEM for UNIX implementation archives were released by Chuck as either rzsz.arc (aka RZSZ.ARC, RZSZ.ZOO) or posted (e.g. to USENET) in SHAR format.

I'm aware of collections such as https://github.com/UweOhse/xyz-modem-archive, but if you have or can find any early (e.g. < 1988) releases from Chuck of RZ/SZ for UNIX, please send me links or upload to Vertrauen!

Thank you,

so it's probably RZSZ.*
man this guy could have done a better job naming his archives.

i just have the 88 version and the fossil rzsztp archive dated 05-20-88
this fossil one has a unix .pas file

Yup and the newest one is CRZSZ*.*.

Yup. If he were still around, he'd likely agree.

Thanks, but I'm only interested in the C sources (e.g. sz.c, rz.c). Still, hang on to that archive, it might be valuable some day! :-)

Who ever uploaded rzsz-06-05-86.tar to Vertrauen - thank you very much! I think that's the olded version of Chuck's C source I've seen so far.

Do you happen to have any README, MAKEFILE or any other doc/text files that might've accompanied those source files?

I wasn't the one who uploaded that, but I found this zmodem.txt online:

And I just noticed the address for Omen Technology near the top of that is in Portland, Oregon.. They were in my area. :)

That was me.

That's all that was in the file. It came as a zip file that turned out to be a .TRZ file

RZSZ.TRZ: compress'd data 12 bits

I used uncompress -b12 -c RZSZ.TRZ > rzsz.tar

That's pretty much what I uploaded. No additional files I'm afraid.

I just uploaded one from 1987 also.
