The original ELF design was a summation of several RCA appnotes and an
article in Popular Electonics ('78 I'd have to look.). Quest was a
production version of the wirewrapped version. They were popular as they
were cheap and pretty easy to work with.

Later Quest, Netronics, and at least two other had similar SBCs that were
expandable though not always compatable bus wise.

It's an interesting cpu, nearly impossible to write optimized programs as
it's addressing modes and register scheme were one of those if it fit
it was small, if it didn't it got real ugly. Still it was interesting
and it was CMOS.
