System (detail)

Intel 486DX/33 with 8K internal cache; 128K external static RAM write-back cache; 1.2mb 5¼ and 1.44mb 3½ floppy drives; VESA Local Bus SVGA video (TSENG ET4000); 200w power supply.

(07/07/97) Replaced Power Supply
The fan motor bearing had been going into fits of squealing for several months, finally got tired of it and went in search of a replacment. For years I had seen advertizements for PC Power and Cooling in various computer magazines, and I found their website to be an excellent resource in determining which power supply was correct for my system (Standard 230 Slim).
