Like the Standard Model Compukit 1, the Deluxe Model is one of the earliest personal computers sold to the public. Based on our research, only the Comspace 650 is older.
The Deluxe Model was the nicer version of the Compukit 1. Despite the Compukit name, the Deluxe Model was not a kit, it came pre-assembled in a wooden case (the brochure called it a "handsome cabinet"). The Deluxe Model included its very own power source...a 4.5 volt battery...and an very handy on/off switch.
The instruction manual that came with the Deluxe Model was the same as the Compukit 1 instruction manual with the exception of an addendum entitled: Notes on Compukit 1 Deluxe Model and how to use it. The addendum was not very extensive, consisting of just one page and was printed on only one side. The Deluxe Model came with 8 Nand gates (two 3-input Nand gates and six 2-input Nand gates) and 8 Nor gates (two 3-input Nor gates and six 2-input Nor gates).The inventor of the Compukit 1, Dr. Ravi Raizada, taught at universities and obviously had experience with students. The addendum states, "The electonics in Compukit 1 Deluxe Model is 'student proof' and will not normally get damaged due to accidental incorrect patching, provided that the recommneded 4.5 volt battery, or equivalent, is used. (The emphasis is his.)
One of the most common questions we get when someone sees a computer from this era is, "But what could you do with them?" The Compukit was intended to be a teaching computer but it could be used to solve problems. That instruction manual that came with the Compukit 1 included problems such as how to construct a coincidence circuit, how to create parallel comparators and how to verify DeMorgan's Laws among others. The addendum for the Deluxe Model did not contain any new "exercies/problems". However, the addendum did point out that "many more circuits can of course be constructed by the imaginative student and teacher". And that also sounds like a writer who knows his students.
The addendum was undated but was inserted into an instruction manual dated simply 1970.
