Reply to "MTH PS1 transformer conflicts"

Steve, All good advice above.

Need a good charged battery. An alkaline can work temporarily for testing.

Need to let it start up, and than make sure Voltage is less than 10V for the initial coming out of the reset state. After that you can change directions from any voltage.

Need something closer to Pure Sine wave.

Some if not all of the PS-1 Geeps were very early MTH PS-1. So they are more sensitive to AC voltage. Stuff made in 97 and later are less sensitive to chopped sine wave.

Do you have an old PW 1033 transformer to try? G
