Excellent post Ken. We loved our "Big Iron". I started my operator career at a Texas Junior-College on a mod40, parlayed that into a gig with the State of Texas herding "jobs" through a mod50 + mod40 pair on grave-yard shift, and was tickled pink to land a position with Lockheed-Electronics operating in the five-plex of mod75RT behemoths sporting LCS (Real-Time mods included the clock [of course] and circuitry for four additional interrupts plus the necessary new machine instructions to handle those interrupts, with extensions to the PCP Kernal under OS360RT the beast ran) that NASA used for the Apollo program. We "flew" 16 & 17 and I hung around until the Apollo-Skylab program shutdown. By the early '90s, I'd completed the programmer-analyst-manager progression out to the end of my hands-on main-frame career. The last 25 years have been internet-centric but you might be surprised how often my main-frame chops have come in handy...
