It has been reported that a Sperry 8086 or 8088 PC upgraded with an
IBM CGA card is incompatible with QuickBASIC Version 4.50. The same
configuration reportedly works with QuickBASIC Versions 4.00 and
4.00b.
To correct this problem, turn the "Advanced Features" switch (switch
number 3) on the back of the machine into the off (down) position.
QuickBASIC 4.50 should then work correctly.
Note: Turning off the "Advanced Features" switch may not correct the
problem if you have a Hercules card on the Sperry PC. QuickBASIC 4.50
has not been tested on a Sperry PC with an installed Hercules card,
and therefore, you may experience QuickBASIC 4.50 compatibility
problems.
