The major components of CP/M are 1) Utilities..ASM.COM, etc. There are public domain upgrades to most of these. 2) CCP the command line processor. There are several z80 and 8080 replacements/enhancements to this. 3) BDOS the guts of CP/M. There are several z80 replacements in SIMTEL20 PD2:. I don't know of any purely public domain 8080 versions. I have for example a dis-assembly of the DRI BDOS but it is not public domain. 4) BIOS this comes from the computer maker, or from you, adapted to your machine. There are also some integrated "ZCPR" packages for particular machines. If you want to roll your own public domain verisons, you may need some effort producing a bios, and producing a MOVCPM that will relocate your "CP/M". If you want a legal copy of CP/M, check garage sales, versions for Apple or Commodore. As far as I know, sales to individuals of CP/M 2.2 or 3.0 are no longer possible in the US. Clarence Wilkerson
