edward t,
Sorry but I didn't know the answer but I looked into my Dewey Decimal System Cards for Cat/Mitsu technical experts & voila' your name was at the top of the list.
As you may recall I am (or was) just a simple technically oriented, well traveled, sales/marketing lift truck guy for 41+ years. Then I hung up the spurs & turned it over to those that have not had that much chance to gain experiences - like surviving another recession.
But I do wish to thank all that are gamely employed and pay into Social Security as 1/30,000,000 of you weekly, monthly or bi monthly contribution goes to me. That might or might not make you feel any better - either way thanks.
