[comp.sys.mac] 512K -> IIcx software

kern@arecibo.aero.org (07/14/89)

This is a strange thing I've noticed, when I could
finally afford to upgrade from my 512K to a Mac IIcx
suddenly many of my programs (MacPaint, SuperPaint,
Strategic Conquest,...) appear distorted on the screen.
The monitor is the standard Apple color 13".  The paint
applications create 3 small windows at the top and
Strategic Conquest puts everything in disarray on the
screen.  What causes this?!  And even more important,
can it be fixed?  I'd hate to have to buy these applications
again...

Programs like MacPaint and SuperPaint are designed to run in one bit per
pixel (black & white) mode.  If you try to run them while your screen
depth is set to something other than one bit, you'll get a number of
small screens at the top of your display.

>The paint applications create 3 small windows at the top
This is because you have your depth set to 4 bits (16 colors).  If your
depth is set to 8 bits per pixel, you'd get 5 small windows.  To fix
this problem, just go to your control panel and find the monitors cdev. 
Change to 2 colors (or 2 grays...it doesn't matter) and try running
MacPaint again.  This should solve the problem for these and most other
programs that are capable of being run on a IIcx but designed for 1 bit
per pixel.
   You also may want to get a hold of the Switch-A-Roo f-key.  It allows
you to easily change between two settings (like 256 colors <--> 2 grays)
without taking the time to go to your control panel.
  Be aware that although changing the screen depth will allow many b/w
programs to run on 68020/030 systems, it will not fix old software that
is not capable of being run on these systems.  Many games designed for
the 512 and + (and even SE) won't work on an 020 or an 030 because of
basic differences in the machines.  For software like this, you'll have
to do without or find another program to take its place.
