I was reminiscing about the good 'ol days tinkering with computers: Commodore 64s, GWBASIC, Turbo Pascal 5.0, DOOM and the Autoexect.bat config.sys hacking required to get it running on underprivileged 486s, Amiga 500s, broken Linux 1.0 kernel compiles, EGA video cards and more Sierra games than I can remember. Getting stuff running was hard. Understanding how stuff worked was heaps of fun. Connectivity to other likeminded communities was basically non-existent, so a great book on the topic of interest was like striking gold in Ballarat.
