Here what happened since last post:
  • I've started fiddling and replacing solder as it seems that my solder paste is not that good. Found unsoldered pin header :lol:
  • lifted up 68030 previously soldered tight on pcb so it would not contact the surface - less emt and better cooling :mrgreen:
  • Here diagrom started working, but could not find fast ram. I've tested in manual test range $40000000-$44000000 and found out one bit is always broken.
  • After testing stuff replaced one of the 3v3 buffers, seems like the one soldered had one channel dead - whole build is based on finest China
Now I can get to kickstart, but CF does not boot and I think it just needs some checks - I have a long cable so I've soldered buffers instead of resistor network, might just try RN and short cable.
