SYSTEM.PM - bootable
This is the default system disk for PM. It's equal to Poly's
Exec/96 system disk, except for the printer driver which has been
modified so that PM's printer output can be captured to a PC
device or file.

ADVENT.PM - bootable
This is an old, possibly incomplete version of the mainframe game
called Adventure. It accepts English commands like "open mailbox"
and "go east."

EXEC961.PM and EXEC962.PM - bootable
These are the system disks for Exec/96, the last released
version of Poly's Exec operating system.

EXECWPS.PM - bootable
This is the system disk for the WordMaster word processing
system. It added a menu-driven front-end to the editor and
formatter programs which had been in the Poly system for
some time.

GAMES.PM - not bootable
Several games written for the Poly: Chess, Battleship, etc.
Some rely on Poly graphics characters which aren't reproduced
perfectly on the PC.  Still, most of them are usable.

GAMES4D1.PM - bootable, older Exec/4D
Contains a number of Games for the Poly. To run these games
properly you need to boot from this disk.

LASA.PM - not bootable
Source and executable for a utility which can set the Load Address (La)
and Start Address (Sa) of a file in a Poly disk directory.

SPG.PM - bootable vdisk
This is the System Programmer's Guide disk. It has a TRIX subdirectory
with useful utilities.

WORM.PM - bootable vdisk
This contains the source and executable for a "worm" game, derived from
a similar Unix game. Start it by typing:  WORM

You will see a worm (ooooo@) and a number. Use the arrow keys to direct
the worm toward the number. Touch the number and you earn that number
of points. Touch the edge of the screen, or the worm itself, and the 
game is over.

The worm grows with each number you touch, and it starts moving faster too,
so it eventually becomes more difficult (like most video games).

The source code is included, as is a MAKE file which will assemble
the source to create the executable.
