Hi guys hopefully i can get some direction to get our Apple IIe platinum (607-0288) International NTSC back to life.
Was in storage for a few years now when i turn it on - no beep and we get a hatch display with squares? Thick lines horizontally & vertically? Trying to run self diagnostics we get PP randomly with again a hatch pattern but with characters?
Power light is on
HAL 16R8CN chip gets hot?
Replaced CPU with a spare known working - no change
Anyone have any idea what we need to look at to get it back to life?
