Unknown Color Poker Game
------------------------------
8080A CPU
Four 2716 eproms
Six 2102 Rams
Two 2112 Rams
Two 5101 Rams (Low Power Versions, one connected to Battery)
Four position DIP Switch - DIP 1 changes on screen text from
normal to highlighted as seen in pics. Other DIPs unknown.
Sound?
Date of manufacture unknown. Latest date codes on logic chips is 1980.

TODO: stuck if it isn't immediately coined up at boot.
Game can be tested by keeping COIN1 (5 by default) pressed at boot.
