Apple IIe STK Asic Clone (Maybe Orange) repair.

Defect:

  • Short-circuit on all voltages.
  • Black/Garbage screen.

Replaced parts:

  • 10 x Tantalum Capacitor 4.7uf (replaced with Electrolytic Capacitors)
  • 3 x RAM OKI M3764A-15 in Short-circuit.
  • 1 x ROM 1 (EPROM 27128)

Note:

I have to thank immensely my friend Alessandro Polito for providing me the dump of the ROM 1 of the Orange (Apple IIe Asic Clone)
