A ‘Byte Shop’– style board The later production ‘Byte Shop’–style of this Apple-1 is indicated by discrete component dates which match other known Apple-1 boards of similar vintage, assembled and sold by Apple in the fall of 1976 and early 1977. On the left side, the board is marked: “Apple Computer 1, Palo Alto, Ca. Copyright 1976.” Unlike many of the known Apple-1 boards, this unit has not had any modifications to the physical board, and the prototype area is clean and unused. This Apple-1 board bears a marking on the reverse side, “01-00002,” which appears to be a stock ID number from an unknown third-party reseller; it differs from the numbering scheme traditionally attributed to The Byte Shop. This is the only known Apple-1 example which uses this numbering pattern, ink, and handwriting. Apple itself did not assign serial numbers to the Apple-1.
This Apple-1 has been wired to use 8K of onboard DRAM This Apple-1 has been wired to use 8K of onboard DRAM. Revolutionary at the time, the standard Apple-1 included 4K of inexpensive dynamic random access memory (DRAM), which could be expanded to 8K on board or 64K externally. Most computers in the Apple-1’s price range used more expensive static memory (SRAM), which limited them to 1K of memory for a similar cost. We still use DRAM technology today in computers, mobile phones, and electronics.
