Hello everyone,
I have been building my first midibox project, the minimal SID, and I'm having problems already. I was hoping someone out there could help. Here is my setup:
18f4685 pic from smash as well as the core and sid boards
Sid ver R3A
Core ver R4D
6581 SID chip
and the simple (not optimized) psu version with parts from a c64
The story:
I tested all the voltages on both boards as directed, and found that everything was ok, I then plugged in the ic's and tried out the core, and loaded in the sid application. Everything worked fine on the core except the backlight did not come on the lcd (but I could live with that). I was not getting any audio out of the sid (tried the test tone, then connection testing) and that failed. So I checked my connections from the core to the sid, (the sid was getting hot, so I knew something was going on...) then the c64 pwr supply went dead. I had another one handy, so I tried that one, and it worked for a while, then the regulator seemed to smoke a little (or was that my imagination?) and then everything stopped working again (fried power supply) I know this because I tried using it on my commodore computer, and it didn't start up. I know I have done something stupid, but I just can't figure out what... Checked all connections and soldering...The diagrams on the website for the connections are not the same as the version of the board I am using, so I had to make some educated guesses. Maybe that is were things went south.
Now I need to find some other way to power my project (all out of c64 power), I have a 12vdc 800ma transformer... Could I use that? If not any suggestions that I could find at radio shack? How do I wire them up? I haven't seen any diagrams with info on how to hook up anything other than a c64 psu.
Well, thanks for reading my story, and I hope this hasn't been covered ad nauseam, but I really have looked and tried, and now I'm stuck. I can't wait to get this working!!
All the best,
Jordan
