QuickBasic Versions 3.00, 4.00, 4.50 Patch for IBM PCjr
Last reviewed: February 16, 1996

Article ID: Q27252

SUMMARY
QuickBasic Versions 3.00, 4.00, 4.00b, and 4.50 do not run on the IBM PCjr. This incompatibility results from the ROM BIOS of the IBM PCjr, which differs from that in a standard IBM PC.

MORE INFORMATION
Through individuals who are using QuickBasic, Microsoft has become aware of several versions of a patch that claim to correct this incompatibility problem. The following is a list of sources for this patch:

 &quot;The Junior Report&quot; magazine, December 1987, Page 24. On the Twin City PC bulletin board at (612) 888-0468 or (612) 888-7570, the filename for the patch is also INT9JR.ARC.  Synetics Software and Systems sells a cartridge called &quot;Quicksilver&quot; that can be used to make QuickC run on the PCjr. A customer reported that this took care of a duplicate-keystroke problem in QuickBasic. The cartridge costs $34.95, and can be obtained by contacting Synetics Software at the following address and phone number: P.O. Box 53501 San Jose, CA 95153-0501 (408) 281-7780 

These patches were developed by individuals who are using QuickBasic on the PCjr, not by Microsoft. Microsoft gives the above references to individuals in need of the patch, but in no way supports or guarantees the patch.
