Marc Venis’s ELF

The striking thing about ELF builds, as opposed to some of the mass market vintage computers, is the dazzling variety of forms the machines take. Marc Venis submitted the photos below of an ELF with the controls mounted above the circuit board, with discrete LEDs for a display — rather like the present data Membership Card computer.

Marc writes: “Here's my ELF that I built in 1977 from the 1976 Popular Electronics construction article while in high school. I had a lot of fun with it and learnt a lot. Over the next couple of years I added more memory, cassette interface, hex keyboard and relay output. I just took it out last week and was surprised to see that it still works and I still have my binary ‘read/write’ skills after 30 years.”
