64K Memory Expander V2 (CA)

When the ADAM left the factory it carried 80K of memory — 64K of working RAM plus 16K reserved for the video display. That was generous for 1983, but large documents and programs filled it quickly. This Coleco 64K Memory Expansion Card plugs into internal expansion slot #3 (the slot Coleco set aside specifically for memory) and raises the system total to 144K.

The extra memory is felt most in SmartWriter, the ADAM's built-in word processor: it adds roughly 64,000 characters of workspace — about 32 pages of double-spaced text — so a long document no longer has to be broken across several files. Under the CP/M operating system or SmartBASIC, that same RAM can instead serve as a fast RAM‑disk or print buffer. This is Coleco's second board revision ("v2") of the card.
