Apple I was based on an 8-bits microprocessor, MOS Technology's 6502, running effectively at just below 1MHz. The 6502 was similar to the more expensive 68000 from Motorola. The Intel 8080 was also in the market, but the 6502 was chosen primarily because it was cheap. The computer had a build-in video terminal, sockets for 8KB of RAM, a keyboard interface, and a cassette board ment to work with regular cassette records. The "computer" was simply a motherboard. The user had to povide a keyboard, a AC power adapter and a display device (monitor or television). The display had 24 lines of 40 characters each. It was introduced at a price around the 600€ that included 8KB of RAM and a tape of Apple BASIC programming language.
