pingosimon Posted July 28, 2009 Report Posted July 28, 2009 I got my CORE up and running!I soldered everything onto the SID module board, and tested the voltage between pin 14 and pin 28 of IC!, the SID chip plug. I'm only measuring 6.72 volts. I'm using a 9v battery and connecting it to J1 of the SID module. 6.2 volts when I change the polarity. Measuring the battery alone gives me 8.5 volts.What's going on?

nILS Posted July 28, 2009 Report Posted July 28, 2009 Connecting the 9V battery to J1 will not work. The rectifier produces a voltage drop and the 7809/7812 will not produce the desired voltage. The input on J1 needs to be ~3-5V above the desired voltage. Quote
pingosimon Posted July 28, 2009 Author Report Posted July 28, 2009 ah that makes sense. I just put together another SID board and got 6.6 volts. Glad to confirm I didn't do anything wrong! Quote
