I recently aquired an old IBM 300PL 6862-82U computer at a tag sale and put in new RAM totalling 768MB( RAM used was 3 256MB DIMM-nonECC The machine booted up to the IBM blue screen and tried to boot using Escape and or F1. key. Nothing happened when the keyboard keys were used. My monitor is a VGA unit and the keyboard used is an IBM PS/2. Any thoughts on the problem. Thanks Fred
