Z System Upgrades CP/M
Z System is first-rate, state-of-the-art software for your CP/M machine.
ZCPR has been with us for over five years now, and has enhanced computer
productivity for thousands of CP/M users. Z System is now a mature
replacement for CP/M 2.2 or CP/M Plus, yet is "backward compatible" with
almost all programs written for CP/M. This means that you can still run
the CP/M programs you now use, yet take advantage of greatly increased
power and performance at the same time.
NZ-COM and Z3PLUS form the heart of Z System. They replace the most
visible parts of CP/M 2.2 and CP/M Plus respectively, adding enhanced
command processing, named directories, vastly improved resident
commands, flow control processing, error handling, and much more. But
it isn't necessary to master all of these (at least at first!) to take
advantage of NZ-COM and Z3PLUS. In fact, though both packages come with
several disks of software and excellent manuals, almost anyone can
install either of these packages on their CP/M computer in just a few
minutes' time. The price for either NZ-COM or Z3PLUS is $69.95 plus $3
shipping.
The next step up in sophistication for CP/M 2.2 users is ZSDOS. ZSDOS
replaces the less visible portion of CP/M 2.2 which controls program
input and output. Through clever coding and exhaustive testing, the
authors of ZSDOS offer significant improvements in performance, safety,
and versatility for CP/M 2.2, including file time and date stamping,
file archiving for faster backups, public files (accessable from all
user areas), path access to files, and improved error messages and
handling. As with NZ-COM and Z3PLUS, ZSDOS installation is completely
menu-driven. ZSDOS comes with a collection of state-of-the-art utility
programs and a 140 page manual to help you make the most of the extended
features. ZSDOS costs $75 ($60 when purchased with NZ-COM) plus $3
shipping.
Another path to system enhancement for CP/M 2.2 users with hard or RAM
disks is available in the form of BackGrounder ii (BGii). BGii allows
you to "suspend" any program at the touch of a button and use a wide
range of resident commands such as DIR, REN, ERA, CALC, or TYPE. Then
hit the button again and BGii quickly returns you to the program you
suspended, right where you left off. Or use BGii's SWAP command and
you're back at the CP/M prompt, ready to run any other CP/M program.
When you're through, SWAP again and BGii returns you to your original
program, exactly as you left it! Advanced "Cut" and "Paste" commands
are also available for many terminals, allowing you to transfer sections
of screen directly from one program to another. Print spooling,
advanced key redefinition and recording capabilities, and a beautifully
designed 140-page user's manual are included. Installation is
menu-driven and easy. BGii is compatible with either ZCPR or CP/M 2.2,
and costs $75.00 plus $3 shipping.
Last but not least is DosDisk, a small but powerful program which allows
you to read or write DIRECTLY to MS-DOS disks with your CP/M computer.
No more file transfers--simply insert a standard MS-DOS DSDD diskette in
your CP/M machine, type "DosDisk <drive>:", and away you go--all files
on the diskette are now accessable by all of your CP/M programs--even
files in MS-DOS subdirectories! DosDisk comes with a handsome 38-page
user's manual, and is available preconfigured for most machines at just
$30.00 plus $3 shipping. DosDisk is compatible with either ZCPR or
CP/M 2.2.
These and other fine products for CP/M and CP/M Plus are available from
users groups around the country, or directly from Z Systems Associates.
