Got a defective vectrex to repair for fun and its an awful job
Hi folks.
Ive been working on a vectrex for fun.
Testing up to try and figure out the big ol' white dot.
As of now. For the original chipset and all.
The cpu was cooked and sending a R/W constantly to vectorial chip causing the white dot.
The rom was cooked.
But it was lightning up.
Ive been working on it for a while now.
Ive recaped everything, swapped the vectorial chip , the cpu and... the rom.
The flyback as a primary coil voltage of 70v.
The capacitor C503 exploded on my face cause i peak at 27v and not 25v ( my dad laughed at my sorryass)
Now i think that capacitor explosion cooked the cpu and the vectorial chip.
And of course no display since the vectorial chip doesnt feed the signals to the amplifiers to boost the 50v necessary to activate the secondary of the flyback.
I can't wait to finish it up!
