Marketed as an easy-to-install, inexpensive alternative to replacing the hard drive, Multimedia Stacker frees the 640 kilobytes of conventional memory, which most DOS-based games require to run properly, and moves it to a protected area of extended memory
* Extended memory

Prices: $9500 (HP 53310A modulation-domain analyzer)> $500 (option 001 extended memory
)> $1600 (option 010 oven time base)> $1450 (option 030 channel C)> and $250 (option W30, which is two additional years of support and three years of return-to-HP support).
Expanded and extended memory
alleviate this problem.
