I bought two pcbs from that seller. Indirectly. So, be carefull .. at least the one (the other is still in the us - so i can't check it yet) was broken.
Easy to repair (just tons of basic ttl) as long as the uncommon (INS8154, DP8350) chips are ok.

Sorry for digging-out this this damn old thread.
I have finally got (two) Vega PCBs and made (one, so far) partially work. Quite weird pcb , inverted colors, unique 22x2 pinout (guessed... ). A lot of faults, broken pins and other crap. Of course board was sold as "working"... Has an old "OK" sticker. So probably that's why...  There's an update on my blog ( link in prev post), including video from attract mode. If someone needs help with vega pcb ( color inverting, pinout.. whatever) - pm me.
Happy new 2012 year
