Memory Expansion, Mouse For PCjr
PCjr Booster, an expansion card which adds 128K of Random Access Memory (RAM) to the IBM PCjr, has been introduced by Microsoft Corporation. The booster also is available with a serial mouse which supports Colorpaint, a drawing program for the PCjr.
In addition to the memory expansion, the booster includes a clock/calendar, mouse support, and a copy of Microsoft's Flight Simulator.
It enables the PCjr to run languages and large programs such as Microsoft's Multiplan and Lotus 1-2-3 at faster speeds. JBASIC, a software enhancement to the IBM BASIC cartridge, also is included. It allows standard BASIC programs to run on the PCjr as much as 22 percent faster, with twice as much screen memory.
The PCjr Booster with sockets for 128K of memory retails for $295; with the memory included, the retail price is $495. Microsoft's serial mouse is available for $195.
