PMs have been exchanged.
25ish years ago I was in British Library mining for SC/MP info and code, eg NIBL in Doctor Dobbs', etc.
And I acquired my own copy of a couple of the Mystery Pages. (But don't know wherefrom!)
The earliest issues of those mid 70's computing magazines were awash with enthusiasm and printed lots of listings, usually straight from a teletype.
The scans Phil has at
http://philg.uk appear to be from an anthology/selection from one of those magazines, a hardback with 310+ pages, about 8x5 inches.
In addition, I scanned the Kemitron Electronics "A Guide to SC/MP Programming".
And Timbucus has taken those JPGs and produced a PDF version which can be admired
