Last year I found a box of material, much of it related to S-100
computers and the Sol I owned in the 1970s. I've scanned it in and
posted it to the Internet Archive:

Folks researching obscure old devices (Biotech Electronics CGS-808,
anyone?) may find something useful. I still have a few documents
waiting to scan, but this is 98% of it.
