Oopsies. A couple of them in yesterday’s big collection.
First, Turbo Pascal 5.5 in the link is a DOS program, not a Mac program. The Mac references appear to be because the Mac inspired certain things about that particular release.

Second, the way I replied to Jeff Hurchalla’s mail suggested I hadn’t started writing the Windows/Linux book. What I should have said was, “If I thought the book would cover the expenses I’d have to outlay to finish it,” rather than “..to write it.” All in all I wrote between 250 and 300 pages and probably have another 50 pages or so of notes. I think that qualifies as a start, by most reasonable people’s definition.
