This would go back to the 50s or earlier. The LGP-30 and comparable
machines are considered as personal computers, too.

The MCM/70 was a Canadian invention though not certain it was a 'first' in
the microcomputer world. Some say the Kenbak 1 was. The Altair 8800, as I

I have a vague memory of visiting the Computer Museum when it was still at DEC,

I had the good fortune of visiting The Computer Museum in Boston in the summer
of 1984. Reading the museum's Wikipedia article, it appears I was there while
they were still freshly setting up their Museum Wharf location, yet hadn't
officially opened yet. Unfortunately I only had an hour (or
At least it's a better title than 'The centre for computing history'

One issue in choosing a book size is that the booksellers have put the book on
a standard sized shelf so it should conform to that size. Very tall books, like
coffee table books are hard to display because they don’t fit on a shelf.
Booksellers really don’t like those (unless they become best
