## Description
This project aims to provide Apple-1 users with a quick way to expand RAM capacity in their systems up to 52 KB and to simultaneously store some Apple-1 programs in
~30KB of on-board ROM, which can be banked in and out via software. The on-board ROM also contains a loader program which is capable of loading programs which span across non-continuous memory locations.
~30KB of on-board ROM, which can be banked in and out via software. The on-board ROM also contains a loader program which is capable of loading programs spanning across noncontinuous memory locations.
The A1C expansion card allows via the physical switch to completely disable the ROM/loader program functionality which takes up to the 2 KB of memory (`$4000-$47FF`)
and to provide continuous 44KB wide RAM address space instead.
