My Dad ( a former Staff Design Engineer & VME for IBM (circa 1950's-1990's) now deceased, would have been my 1st source of inquiry & I'm sure instantly forthcoming with a solution to my 'conundrum' that I've inadvertently deleted.
Yes, I'm a 'pleb', fallible & apologetic (Mea culpa: Latin) .
Thank you, in advance for a viable solution to my dilemma if at all possible.
Cheers mates!
