Novag Aquamarine RISC II 26.6MHz
Third repair
With the experience gained in the Second Repair, I decide to repair another unit but this time improving the process:
Removal of the top film using heat, to avoid bending it.
Copper tracks, instead of aluminium.
Plastic spacer film (0.15 mm), instead of cardboard (0.2 mm).
AWG30 cable (0.25 mm), instead of varnished copper wire (0.4 mm).
Here are some pictures of the process...
