View submission: I'm still struggling understanding RAM types/upgrades for OCS 500.
Yeah.. if I remember correctly.. the Amiga 500 I met back in the day all had a trapdoor "extra memory" as it was called here in Sweden.. most of them with a clockchip that needed a battery.
This was needed for many games and increased your chip ram.
I've since learned that a really old Amiga 500 couldn't really use the additional ram as real chip ram and would turn up in your os as fast ram but really not be fast ram.. and this is called slow ram.. funny that..
Fast ram.. the kind of memory the CPU didn't have to share with the rest of the computer, was expanded via the Zorro bus on the side.. my mate had a 52mb disk drive with 3 meg's of ram. Dunno what it was useful for though cause it didn't help when you were gaming . Could actually break some games iirc.
The fast ram, if it only were a memory upgrade could support 8 of those.. If you got a coprocessor or turbocard.. you could add up to 128mb.
I don't know how to identify your Amiga so I just give you the wish of best luck..
What do you want to do with your old Amiga?
There's nothing here!
