I got this Toaplan Out Zone PCB for a repair:

Out_Zone_PCB

When I powered it up I was greeted by this screen:

object_RAM_error

This kind of error doesn’t necessarily imply that a RAM chip is faulty but also that it can’t be “reached” from the device which wants to read/write it.In this particular hardware the device in question is a custom ASIC sprites generator marked “FCU-2” also used in other Toaplan games:

FCU-2_ASIC

I went to inspect it and found some lifted pins:

FCU-2_lifted_pins

Blocking the PCB with a vise, I did a reflow of the involved pinsFCU-2_reworking

100% fixed!
