Same here. This is the "late rev A" board, which is new enough to have the
enhancement but old enough to be in a beige //e.

The 820- number is what is referred to when something requires a rev B or later
board.

This is correct. 0064-A didn't last long since it couldn't do DHR graphics.
0064-B lasted until the enhancement came out.

I've never seen under the hood of one but they should be easy to spot since
they only have one ROM chip.
