His daughter Joyce Weisbecker took to programming his prototypes, becoming the first female video game designer in the process, using his language called CHIP-8.
He built a demonstration home computer powered by the 1802 called FRED (Flexible Recreational and Educational Device) that utilized cassette tape for storage and a television for display.
In the time between 1971 and the production release of the 1800 series processor, Weisbecker developed a range of inexpensive application circuits for use with the 1800s, including light guns, card readers, and cassette interfaces.
Weisbecker designed the 1861 PIXIE graphics processor in 1975 as a minimal-cost simple video output for microcomputer systems.
In 1977 further articles added 1861-based video to the Elf, similar to the Studio II, as well as additional memory and rudimentary operating systems.
Titles such as "Fun and Games with COSMAC" (IEEE Electro #77, April 1977) and "An Easy Programming System" (Byte, December 1978) demonstrate this, as do the contents of his many papers, manuals, and articles.
The COSMAC ELF continues to be a popular educational microcomputer construction project to the present time, and several newer designs have been based on it.
They are also studied with respect to design longevity, as systems based on the 1802 have been run and supported in production for over 30 years in a range of applications.
