The 3210 looks like a much earlier design, prior to the inclusion of 
microprocessor control. Date codes look mid eighties, by which time 
companies like FTS did have microprocessor control. Maybe their later 
design products ran in parallel because of gov or esa contracts. In 
theory, the more straightforward hardware design should make it easier 
to keep running, tube life permitting, assuming the info can be found.

Thanks for sending it anyway - it all adds to the sum of knowledge...
