Apple 1 Block Diagram SB Projects At the heart of the diagram we see the 6502, Apple 1's microprocessor. All timing is derived from the terminal circuitry. And that's where the processor's 1MHz clock signal originates from too. The memory consists of 2 banks of 4k dynamic RAM and one tiny ROM with only 256 bytes, occupying an entire 4k bank. Apple 1 display circuit on an FPGA | Applefritter 1). It is the machine that launched Apple puter. 2) The DRAM refresh circuit led directly to the extemely clever use of memory mapped video DRAM with automatic refresh in the Apple II. The Apple 1 design is a combination of an improved TV Typewriter circuit along with a very basic 6502 circuit. Some parts of the circuit barely worked.
