Amiga 1200 Chip memory: recorded figures
Metric Value Evidence Basis Method Source
Memory capacity memory 2 MiB Confirmed Vendor-rated Design capacity Stated by the vendor The maximum Chip memory, which the manual records as the standard configuration by the time it was written. Machines shipped with 1 MB on the motherboard. Chip memory only: what the AGA chipset can reach. Fast memory added in the CPU slot or the PCMCIA slot is invisible to the graphics hardware and is not counted here.

Editorial notes

Shipped as 1 MB on the motherboard, expandable to 2 MB; the service manual records that systems were by then configured with 2 MB as standard. Fast memory, which the custom chips cannot see, is a separate expansion.
