Today in “Things I don’t understand”™️ we have “how to figure out if my IBM 5150 has access to all its RAM”, “how to interpret the manual clarifying the dip switch positions on the motherboard”, and “how to get the Hercules video card to display graphics”.

Granted, electronic #RetroComputing is quite new to me, but this has me feeling like a complete dunce. Otherwise, I like the #IBM5150 / #IBMPC / #IBMPersonalComputer quite well.
