Above, Stewart Marshall's machines sport toggle switches on vertical front panels reminiscent of Altair. Stewart describes his setup: "Here is a photo for the Gallery of two of my little front panel Elf machines which have Lee Hart's BASYS boards in them; (coffee cup for size). The top machine uses an external wall wart power supply and the bottom one has built-in 115v AC power supply. Also in the photo is a handmade replica of the old Oliver optical paper tape reader hooked up to the bottom machine to enter code from paper tape. I have a DSI punch tied to my Mac's serial port, with the CrossBow 1802 Cross Assembler for code work and a custom AppleScript drives the punch. The Elves have both serial and parallel ports and onboard EPROM space. I can use them either manually from the front panel, connected to a Mac, PC, or dumb terminal with serial cable, or running from the ROM in standalone dedicated situations such as security or driving a machine tool, engraver, etc. The front panel logic is also all Lee's design except for one modern chip substitution I made; and I used metal cases from old printer buffer and sharing devices."

Bill Kos recently assembled the cool blue ELF in these three pictures based on the original Popular Electronics article. The case and panel are oak, and a switch has been added to turn off the display. Bill says he plans on adding battery backup, and points out that the display consumes 90% of the power. He also added a RJ-45 jack for future interfacing to EF lines and Q.
