  1. English Version BIOS Hardware specific machine code BDOS I/O routines and BIOS interface CCP Console Command Processor - (may be overwritten) Traditional CP/M-80, originally bulky 8080 Code, uncomfortable, awkward. Applications and tools most likely hard to transfer onto other CP/M-computer systems

  2. BDOS Drive vector-reset with CTRL-C mandatory, no timestamps SUPRBDOS Rather poor - terminated at an early state Z80DOS V 1.0 many errors V 2.0 very useful P2DOS Advantage: CP/M Plus-timestamp compatible - but buggy ZSDOS Originally commercial high development effort

  3. CCP Console Command Processor - (may be overwritten)

  4. CCP Console Command Processor - (may be overwritten) Step 1 slim Z80-Code replaces bulky 8080-Code

  5. CCP Console Command Processor - (may be overwritten) Step 1 slim Z80-Code replaces bulky 8080-Code Step 2 new commands conditional flow control

  6. CCP Console Command Processor - (may be overwritten) Step 1 slim Z80-Code replaces bulky 8080-Code Step 2 new commands conditional flow control Step 3 security mechanisms (Wheel-Byte)

  7. CCP Console Command Processor - (may be overwritten) Step 1 slim Z80-Code replaces bulky 8080-Code Step 2 new commands conditional flow control Step 3 security mechanisms (Wheel-Byte) Step 4 named directories TCAP Terminal-standardization

  15. standardized TERMCAPs minimize installation time VLIB 4D - portable pseudo graphics through bloc graphic characters

  16. VLIB 4D - bloc graphic characters

  17. ZCPR- Mini-applications can be run on any configured Z-System without any further installation, thanks to TCAP standardizing! All elements of the Z-System , like named directories and so on may be used. Here only some examples: ZFILER - central part of the Z-Systems The ZDB database and the ZDT calender. A sort of Norton Commander, the SCOPY tool:

  18. “V” - the comfortable Viewer - an ideal companion for Zfiler

  19. The “Visual LibraryUtility”-VLU - a very helpful tool!
