Yeah, the DOS games seem to not have been mucked with, only some of the Windows games, likely to get it to work in Win 7/8/10. That’s okay, I spent the 200$ and went bargain bin hunting on eBay and got as good a set of popular games as I’ll ever have. CloneCD and some time should be fun enough.
On the flip side, I finally got the audio chips, and after I failed to get the first chip in (one of the pins came off, doh), the second chip got successfully soldered in place. Very exciting (as well as incredibly hard to solder that audio chip in - hardest thing I ever did solder, hands down), so I went and hooked it up to the VGA->HDMI cable to test, put on some 5v 3A raspi power, and…. *drum roll* .... Nothing…
The light on the Vortex86DX does turn on, that’s good, and I went back and checked all my work, couldn’t find anything that didn’t look right. Went and took the ohm meter to some of the resistors and all the ones I checked seemed to be good. Took out my cheap tester and tested as many caps as I could, although it’s cheap and saw a few as diodes (pretty sure it’s just cheaply made crap tho, the tester that is), but looked fine… The LDO didn’t seem to be putting out 3.3v on the center pin, even after the capacitor, although I did put a 1.5A one in there (since 1.2A was out), so hopefully I’m just a dummy.
Ugh… Gonna have to pull out my equally pathetic analyzer to see what kind of signal the VGA is putting out. Might have to finally break down and get one of the nicer 500$ ones, though.
Any ideas where to start? Included pics of what my V1 board looks like atm. Any help is appreciated, given I am a programmer by profession and electronics by hobbist.
