My first computer, back in 1978, was a COSMAC Elf, specifically Quest Electronic’s Super Elf, based on RCA’s 1802 CPU.

The COSMAC Elf computer was first described in Popular Electronic magazine in 1976. It was a lot simpler and much less expensive than other computers at the time. Several companies, most notably Netronics & Quest Electronics started selling kits and completed systems based on the design.
