I remember seeing advertisements for it, but I never had enough money in those years to buy something like that. I know I wanted one.
I had to settle for the Quest "Super Elf." It took me awhile to save up the $100.00 it cost to buy it back in 1977.
I agonized over the price of the C1P but the Mrs okayed it in’78.
Moved up later to a Casio laptop with mem expansion and ROM modules for spreadsheet and word processing that kept memory on a micro cassette. The display was a four line by 20 character lcd screen. I was in the US Army and became a computer tech for their mainframes, the IBM 360 initially and the the IBM 370 later on.
OF course that was all after my days on the ILLIAC IV project at NASA Ames in Palo Alto, CA.
