SWITCHED EPROMS

[Robert W. Hughes]

Hi, Justin, it's me again. I saw your circuits for the multi-table
eproms and would like to make a suggestion. Instead of a pull-down
resistor and a switch to Vcc use a pull-up resistor to Vcc and a switch
to ground. Switch open=1, switch closed=0. This is a better match to
circuit requirements (inputs are usually current sinking) and gives a
more reliable system with less chance of noise problems.
