First thing, replace all the SMD electrolytic capacitors throughout the unit, on the processor board, acquisition board, and front panel (maybe the firmface board if fitted and caps are there too? I'm not sure on that model)
I would suggest making note of values, then removing them all, then putting the bare processor board and acquisition boards through the dishwasher.
Washing by hand is fine too if no dishwasher is available.
Repair any damage caused by the leaked electrolyte and install new caps.
If you need a replacement VCO board (the little PCB sticking up off the acquisition board) I made a replacement design, and may have a few spare blank PCB's laying around if you need.
The two segments alternately flashing on the 7-seg display on the processor board indicate that the processor has sucesfully booted and is running, so I'd concentrate efforts on the acquisition board, besides any electrolyte corrosion damage as previously mentioned.
That ROM chip you took a photo of is the boot ROM (basically equivalent to the BIOS in a standard PC), and can be ignored as working as the unit boots ok.
