View submission: I'm still struggling understanding RAM types/upgrades for OCS 500.
Chip RAM: Behind fat agnus, usable by both chipset and cpu.
Slow RAM: Behind fat agnus, but only usable by CPU. Still blocked for CPU when chipset is accessing Chip RAM.
Fast RAM: Exclusive to the CPU, never blocked by chipset.
Get this for 8M fastram + ide: https://amigastore.eu/en/929-ide68k-gottago-fastram-8mb.html
With these two expansions together, you're set.
Then you can use mkick (on aminet) to load newer kickstarts into fastram whenever you need access to modern AmigaOS, while having excellent compatibility with software from the era on power-on, using the kickstart in the rom socket.
There's nothing here!
