Which came first, the Commodore PET 2001, TRS 80, or the Apple II??
I have pics of a PET 2001 Prototype at the Jan 18-20 Gametronics convention. In and of itself, this is not really anything special considering the PET was also known to be displayed at the Winter Consumer Electronics Show also in January 1977. It's clear that there existed in January of 1977 a working prototype of the PET 2001. This machine was being marketed publicly.
Was there a working Apple II prototype in January 1977, more or less recognizable as an Apple II? There is no evidence to support this.
I am told that was a working TRS 80 in January 1977.
Here are pictures of the Commodore PET 2001 Prototype at Gametronics Convention January 18-20 1977
