I think it's wonderful (and remarkable) that DEC employed David Ahl in educational product marketing, where he basically (indeed BASICally) bootstrapped the computer gaming field.
After DEC killed its first microcomputer projects (not wanting to compete with its own minicomputer business) in 1974, Ahl left DEC to found Creative Computing and catalyze the microcomputer (and BASIC gaming) revolution of the 1970s. DEC later realized its mistake in ignoring the growing PC market, but never became a major player until they were eventually (and perhaps poetically/ironically) acquired by Compaq.

Edit: I thought this companion guidebook was interesting and wonder if DEC ever published its sequels:
