A604F Flip Chip Module DEC 2 Bit D-A Converter

The A604 revision F is a 2 bit D-A converter




Difference from Revision E on Vince Slyngstad's site is a date of 2/68, and a bit of trace going off the edge of the board from what is probably one of the grounds.

Will verify the components and etch and update.

Vince's A logic page is here.
