- Subject: Legal Status of ZCPR3 and ZRDOS
-
- Dear Art:
-
- On page 46 of Issue 25 of The Computer Journal appears a letter from
- "D.D.". Item (4) of the letter states "The Z-System is public
- domain, but surely the BIOS from Micromint or Ampro is not public
- domain; specifically, which files is one allowed to copy for friends?"
- Our reply. First, Z-System is not public domain, period. All
- aspects of ZCPR3 and ZRDOS that make up the Z-System are copyrighted.
- But ZCPR3, CP/M CCP replacement, is special. Programs and utilities
- written by Richard Conn can be freely copied and given to friends, but
- they can not be sold. You need a license from Echelon to sell ZCPR3
- programs.
- Second, ZRDOS, the CP/M BDOS replacement combined with ZCPR3 is
- Z-System, is licensed and supported by Echelon. You need a license
- from Echelon to sell ZRDOS. And it is against the law to copy it and
- give to friends. Subject files are ZRDINSnn.COM and ZRDOSnn.BIN,
- where "nn" is the version number. But support utilities associated
- with ZRDOS can be freely given to friends who have obtained ZRDOS
- package from us. These are AC, VTYPE, VIEW, SFA, DFA, COMP, DOSERR,
- DOSVER, DISKRST, LOGGED, DRO, SRO, and SRW. Each was written to take
- advantage of features of Z-System and thus only run if ZRDOS is
- present.
- Z-System is fully copyrighted by Richard Conn, Dennis Wright, and
- Echelon. To sell and support Z-System is one reason Echelon is in
- business.
- Last, those who receive Z-System fully installed on their
- computer, e.g., on Micromint's SB180, and want to become involved with
- the Z-System community, should subscribe to our fortnightly
- newsletter, Z-News. It sells for $24.00 per year. Also we have a
- free catalog of interesting Z80 and HD64180 Z-System and CP/M-
- compatible software products. Additionally, we support over 60 remote
- access systems called Z-Nodes around the world acting as electronic
- forums for people interested in Z-System. Latest program versions
- appear first here.
- Art, thanks for supporting our kind of computing--keep it up!

- Cordially,

- P.S. Please check with Micromint and Ampro to get their BIOS position.
- We cannot speak for them.
