From the Book's Introduction:
-----------------------------

CP/68 is a floppy-disc-based operating system that supports standard 
peripherals such as a line printer, CRT console, paper-tape reader and punch 
and, auxiliary consoles.  The preliminary specification was described in 
EDN's Software Systems Design Course (Chapter 7), November 20, 1978.  The 
current version is based on that specification and an improvement on it.

The operating system's modularity makes it easy to manage conceptually, and a 
pleasure to use.  It is the most powerful system available for the 6800 
family of microprocessors.

This book presents the entire operating system in seven distinct parts.  Part 
I introduces you to the operation of the programs; Part II adds the Advanced 
User's Guide; Part III covers the system's operation in detail; Part 4 
explores the operation of the formatting utility; Part 5 introduces the 
random-access file support; Part 6 provides the information you will need to 
adapt the software to nonstandard hardware configurations; Part 7 gives 
complete source listings.

Review of "CP/68: An M6800 Operating System"
--------------------------------------------

This review is from a magazine (that appears to be very similar to what 
"InfoWorld" used to be like) called "Intelligent Machines Journal."  The 
review is from the March 14, 1979 issue on page 3.  Here is the review:


"CP/68: An Operating System for 6800's"

CP/68, an operating systems for the 6800 family of microprocessors, is 
available from Hemenway Associates.  A combination of memory-resident and 
transient commands provides the system's flexibility, and the user can add 
his own commands to the system.  PIP, the Peripheral Interchange Program, 
allows transfer of data between physical devices.  Wildcard operation of all 
disk commands allows the user to specify files either ambiguously or 
unambiguously.

Other features of the operating system are:

   - Complete device-independent I/O
   - Sequential and Random file access
   - Dynamic allocation and expansion of files
   - Command files
   - Chaining and overlaying of user programs

All of Hemenway Associates' other software runs efficiently on CP/68.  The 
operating system supports functions that the Strutbal+ compiler used to 
provide in its runtime package.  The operating system run on Percom, ICOM, 
MSI, Smoke Signal, Micropolis, and SWTC Systems.  OEM inquires invited.
