@SDF @larsbrinkhoff “Borrowed” sounds shady. They rented time on the Albuquerque School District PDP-10, after (mis)using Bill’s student account on the Harvard PDP-10 for initial development of Altair BASIC.

@SDF I see. I suggested the same thing when we digitized the original logotype done by a graphic designer, and got shot down.

That would have been 277432. 😁

@SDF After my time.

@me @SDF Well, it’s a PDP-6/-10 HALT instruction (a variation on the JRST branch instruction), but I don’t know the significance of the 18 bit address field (277616).

The original XKL logo had an address field which was the SIXBIT for WA<space>. After a reorg and name change, I redid the logo to have an address that decoded to LLC .

@SDF Yay!!!! ❤️🎉❤️

@SDF I know that machine!

@SDF Wow. What’s the provenance?

@SDF Ah, of course. 3 years later, things are getting fuzzy. Thanks!

@SDF I wondered if Piggy had moved, but I recognize the carpeting. Why are there panels behind it?
