Upgrade paths

RAM

512 KB to 1 MB chip RAM via a trapdoor expansion, plus fast RAM through side-slot accelerator boards · The trapdoor slot under the case is a tool-free clip-in expansion, a big reason A500 upgrades were so common.

~$50-$100 for a trapdoor 512 KB expansion at the time

CPU

68020/68030 accelerator boards through the side expansion slot · Third-party accelerators (e.g. GVP, Commodore A501/A590) add CPU speed and SCSI hard disk support.
