Call it twenty years plus tax.<\/p>\n<p>The fact that I can&#8217;t find a notebook battery that I had in my hand day before yesterday is not relevant to the story.<\/p>\n<p>So then I had to fire up the third machine on my desktop**, click the KVM over, and copy the files to something my main machine can read.<\/p>\n<p>Now I know for a fact that the vast majority of my readers (both of them) are suffering <a href=\"http:\/\/www.catb.org\/jargon\/html\/M\/MEGO.html\">MEGO<\/a> with a side of <a href=\"http:\/\/www.urbandictionary.com\/define.php?term=tmi\">TMI<\/a>.

I&#8217;ll explain it.<\/p>\n<p>** Primary machine is a Windoze 2K box. #2 is my Linux box, and #3 is a 486 (or maybe an early Pentium) which mostly boots DOS (with Windows 3.1 if I really need to do that) and runs <a href=\"..\/..\/ccc\/mac\/ReverseEngineering\/PALs.html\">my Expro<\/a>.<\/p>\n<p>(no, those were footnotes.

He had a fairly large collection (as you can see, Arena was #1249 in his catalogue) of shareware disks which he copied to floppies (yours, or supplied by him) for a nominal fee.\u00a0 The <a href=\"http:\/\/www.simtel.net\">Simtel<\/a> \/ <a href=\"http:\/\/cd.textfiles.com\/cica\/\">CICA<\/a> \/ <a href=\"http:\/\/en.wikipedia.org\/wiki\/Walnut_Creek_CDROM\">Walnut Creek<\/a> CDROMs pretty much put an end to this era.
