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:

ZCPR is also available for 8080 systems in a reduced version. The “Full-Blown”

Z-System (NZ-COM) will only run on Z80-CPUs though.

For the technically skilled, a piggy-back NSC-800-board used to be available to plug into the original 8080 socket (most of the time there was none and had to be soldered in by hand) and then Z80 instructions could be executed there as well.

The formerly commercial versions of the Z-System were NZ-COM (CP/M 2.2) and Z3PLUS for CP/M Plus. Both contain the virtual BIOS “ZRDOS”. For CP/M 2.2, ZS-DOS is available as an option. Version 1.0 was free from the start, Version 2.0 should be free by the time you are reading these lines.

Where TPA is scarce, the I/O package may be sacrificed.

Z-System

Z-System

The size of the TPA has yet increased by 1.5K.

Z-System

The ENVironment data are being saved with the specified filename “NZCOM”.

Z-System

Our Minimalist-NZCOM is ready to boot within minutes.

Z-System

CP/M commands are not automatically available if they had not been integrated into the CPR. The DIR command will be replaced by the shortcut “d”.

Z-SystemSDZ may be used as a replacement for the

DIR command by renaming it to DIR.COM.

Most of the times,the values of options in Z-programs can be set with the aid of the tool ZCNFG.

Z-System

The next step is choosing the most suitable terminals (TCAP), that should be capable of displaying bloc graphic characters.

Z-System

Z-System

The slightly outdated tool TCMAKE comes in handy, when no terminal description will fit, like e.g. with the AMSTRAD CPC in CP/M 2.2

Z-System

If the TCAP choice is wrong, a typical screen output may look like this:

Z-System

The displayed TCAP is close to what we want and so the best choice for now.

Z-SystemIf you find a suitable Terminal within the

Z3TCAP.LBR, you can extract it with the commands: LGET Z3TCAP ANSI.Z3T

You can also use the tool JETLDR.COM to load a TERMCAP. This tool is included with the Z-System.

Else you may use the “M” option within ZSHOW to localise the address of the TERMCAP entry.

Z-SystemUse the external command SAVE.COM to capture the loaded

TERMCAP- entry from memory to disk.

Z-SystemYour new TCAP file will then be renamed to NZCOM.Z3T

and added to your Library with “LPUT NZCOM NZCOM.Z3T” to be loaded automatically at system start.

Z-System

Creating the named directories with EDITNDR

Z-System

Z-System

The renamed file NZCOM.NDR is stored within our system Library and will also be loaded at start time.

Z-System

Within CP/M 2.2, there is now also a search PATH. The first and last element should be identical.

Z-SystemYour terminal is set, your environment defined, but

some programs still want more ...

Even if the system does not have a clock, interrogating date/time at system start will help to improve organizing your data.

You did it! Welcome to the Z-community!
