Q38964: QuickBASIC 4.50 Incompatible with Sperry 8086 PC with IBM CGA
Article: Q38964 Product(s): See article Version(s): 4.00 4.00b 4.50 Operating System(s): MS-DOS Keyword(s): ENDUSER | SR# S881128-21 | mspl13_basic Last Modified: 12-JAN-1990 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.
