CC65 patches for Apple1/Replica1 (cc65-2.11.0-diff.zip v1.0 by Dave Schmenk)
Submitted by resman on June 10, 2006 - 4:33pm. Apple I | 2006 | 6502 | Development Tools | Free/Open SourceThe Apple1 is a questionable target for a C compiler due to its small memory size and disjointed memory map. The Replica1, on the other hand, is a near perfect single board target with its 32K contiguous RAM and nice I/O expansion. Compare this with what WDC offers as a single board development platform for $695.
