    I would say the 11.96 is fine and probably within its designed tolerance. In my limited electronics experience, voltages aren't always precisely 12.00000000000V.

    Typically 150s got RRD42s. Which use your typical, standard style CD caddy. I've only ever seen pictures of 150s with RRD42s and the System Specification references RRD42s.

    Can't tell if it's just VMS 6.1 that doesn't like your program or not, but I can't seem to get it to display any times. Compiles with no errors and runs just fine. I suspect operator error. :p
