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.
