Right.

I have a Quest Elf that I built from a kit as a kid. It was the Popular
Science design, pre-1861 video chip. It has a speaker, a Q LED, 8 toggle
switches for data, DMA/EF4 pushbutton, RUN/LOAD/MEMPROT toggles and the
original TIL311 latching hex displays. My PCB is rev 2.1, 1979. I bought
just the PCB and assembly plans for $35 around 1980. The entire kit was
available for $99.

The Elf II was a different manufacturer, Netronics, IIRC. Quest made the Elf
and Super ELF.

Right. An entirely different beast - keypad, ROM, 1861 video, I/O expansion
slot, up to 4Kb on the board, system expansion slot, cassette interface. I
have one, too.
