Both variants were out of stock on 2026-07-24. Open the computer and identify its model, ROM, logic-board layout, and memory-expansion connector before choosing a version. The A2S4000 version requires CPU removal and socket installation; an Apple IIc with ROM 0 must first be upgraded to ROM 1 through 4.
