I suppose my second question would be this:
I also have a ProteusFX that has not been turned on for a long time. When I did, the display came on the normal green, no alphanumeric characters came up, and I could not start the music Demo by holding down the two proper keys to do so.
The filter cap in the power supply section looks intact and nothing smells burnt. Can I assume, given this information to work with, that this module is El Croak-o?
If not, what else can I try? Thanks.
