i have just terminated my CORE module for my SID project. i will do the test in the following days, because i lack the connector for the power supply,. so there is time for some questions! :-) 1) is there any kind of test i can do (apart the voltage control) in order to be sure that the core works, after PIC programming and PC MIDI connection? (some sort of sysex/MIDI communication with MIDI-OX for example...) 2) i have used a TL05 voltage regulator without heatsink... is it safe?? 3) i will not mount the LCD screen. will i have to connect the two trimmers P1 and P2? should i connect a resistor or leave the contacts open?? 4) all the connectors not used in the SID configurations should be leaved open, right? :-) 5) i have a power supply at 16V 800-900mA (don't remember...) is it OK for powering both module?? thank you very much!! matteo
