JOY.SYS
-------

JOY.SYS is a DOS device driver to emulate a Microsoft mouse using the 
TRS-80 Color Mouse (cat. no. 26-3025) or a Tandy joystick.  The Color 
Mouse is actually a joystick internally and plugs into the 6-pin joystick 
port on the Tandy 1000-series.  With the JOY.SYS driver, you can use it 
as a mouse with some DOS programs that support a mouse.  (Note, DeskMate 
already contains a joystick mouse driver, and you might choose to use it 
instead of this driver.)

To use JOY.SYS, add this line to CONFIG.SYS:

  DEVICE=JOY.SYS

There is one option, /CENTER, which makes it easier to control the mouse 
cursor if you have a self-centering joystick such as the Tandy Deluxe 
Joystick (cat. no. 26-3012B):

  DEVICE=JOY.SYS /CENTER

Do not use the /CENTER option with the Color Mouse.  Of course, you can 
also include drive and path in the DEVICE= line:

  DEVICE=C:\BIN\JOY.SYS
