Yup me too! Just pulling a friend's chain... Have been head of IT depts, for several companies, never certified (in anything except mental stuff) but used them all my adult life. Started with Sinclair, TRS80, Commodore, IBM 1450, 360, etc. Don't understand my thesis any more, a digital simulation of an automatic combustion control system on an aircraft carrier. Now retired several times, consulting almost full time and still having fun... Mostly with boats and marveling at the things in the digital world!
