About King 2.5 and RAM: I double checked. Turns out I was mistaken.
It works ok with more than 512KB RAM.

Why didn't I see it before when I checked it? It uses around 75% of RAM for the hash tables. So, when you install 8MB RAM, it puts the hash tables at 2MB-8MB area. I must have only looked at the 0MB-2MB region when I first checked.

Although there really is an R40 that says "R40" on the system info screen: https://www.schach-computer.info/wik...x.php/Tasc_R40
