Apple II Rev. 4 (apr 1, 1979 – may 1, 1979)

Description:

Revision 4 was the next significant change: minimum system became 16K memory and this eliminated the RAM configuration jumper blocks. The change was important enough that it was given a new major part number: 820-0014 (with no revision level on this engineering sample). The production part number became 820-0014-01: Rod finally had his way.
