Whenever I got my Sony MSX2 then I unscrewed it and cleaned it up right away and after that replaced the caps on the spot so thanks for sharing the info :-)

Is there any interest in making new versions of these boards?

I think there could possibly be quite some situations where replacement would be easier/cheaper than repair, provided you plan to sell populated boards as well.

I suspect if the caps have gone so bad they started to corrode everything (hopefully not) then yes, otherwise probably no

New PCBs would be very helpful to anyone whose HIC-1 got damaged by leaky capacitors.

If the HIC-1 is going to be redesigned, its a great opportunity to upgrade it to the CXA2075 and add pads for an S-Video output.

That crazy audio preamp made with a NOT port could be a challenge to tweak if the exact same chip isn't found though.
