> A run-of-the-mill Amiga 500 has 512kb of "Chip RAM" and 512kb of expansion RAM

Nitpick: a stock A500 had just the 512kB Chip RAM. Many users opted to add the A501 RAM expansion with an additional 512kB Fast RAM which was not directly accessible by the graphics hardware. Although labelled as Fast RAM, it was slower than actual Fast RAM due to the expansion architecture.

aka Slow RAM.

Most A500 owners had the 512KB trapdoor expansion. Much software, including games like Monkey Island, would not run w/o at least 1MB total ram.

Today, there are widely-available, cheap trapdoor expansions of open hardware design that offer 1.5MB slow, 512KB (for 1MB total) chip, as well as RTC.
