I wish I had a logic analyzer or at least an oscilloscope to look for signs of life

My thinking is that the graphics chip is able to read video memory, at least partially since it is able to produce these garbled but stable displays I replaced a couple capacitors and now it's trying to communicate  All the information I've found online complains about how hilariously cheaply made these things are, there's bodge wires going all over the place inside it  at this forum http://www.vz200.org/forum/index.phpr u ready to WALK fucked around with this message at 21:11 on Mar 15, 2017 |
