I think this falls in my area of expertise as I'm been doing prototype
HW design and research for the last 10 years for several fortune 50
companies...
The problem is that the layout of the polaris would require lots of
membrane area. Costs go up with area, so in the end the switch panel
replacement would probably cost close to $500 for qty <400.
There are 2 alternatives:
1) Non-form factor switch box (like a roland PG-xxx) which would be as
small a possible to save on costs, but would compromise the user
interface of the instrument (which is part of its character).
2) Which I have done successfullyand posted about on this list is to
drill out the panel and replace w/mechanical switches. This requires
removal of a few IC sockets for clearance on the rigid boards under the
panel. I'm getting pretty good at it, and using a thermal tweezer wire
stripper, its possible to avoid cutting and stripping 150+ wires to
make all the connections.
#2 sounds bad-- but nothing compared to what is done on some hammond
restorations.
I'm not looking to start a business, so please don't be offended by the
commercial nature of the following, but I would be willing to drill and
replace membrane panels for $300 (or more for higher quality switches--
prices range from $.30-$5.00 each!) and I have a spare so it could be
done as an exchange to minimize down time.
