Hi Chris thanks but no, the "lost" book isnt just assembler and appears to cover other than SC/MP stuff too, maybe a compilation by one of the monthlies. The weird thing is that Circuitryboy also has a couple of photocopied pages from the very same 'lost' book, what are the chances!!! The Kemitron book is also very good, thanks to Circuitryboy, but
these aren't the droids we're looking for
