There's a few bits & piece online, maybe not in the "usual" places though:

Also worthwhile noting that Iann Baron 
(https://en.wikipedia.org/wiki/Iann_Barron ) went on to found inmos and 
create the transputer. I worked in Bristol for some time, starting with a 
company founded by some ex-inmos employees in the mid 80's building 
transputer base supercomputers - a CPU with a curious instruction set that 
(coincidentally?) might be a good fit for the BCPL CINTCODE system. I'm 
also sure that the transputer is very much influenced by the Modular One 
too.

BCPL continues on to this day, now a 32 or 64 bit language running on all 
mainstream OSs and processors.
