How about an Exidy Sorcerer - 1978!! Programs and languages are loaded from either a cassette tape, or a cartridge (ROM-Pac) plugged into the right side of the console. These ROM-Pacs are real, authentic, 8-track tape cartridges with a computer circuit-board inside instead of a music tape.
Oh the good 'ole days my first computer that was actually mine was a 12" Apple Powerbook that I got for college...4 years ago. Now those were the days!! haha
