There will be a few Chroma owners here - but the best/first place always
to go for Chroma-related topics will be the Rhodes Chroma web site
(http://www.rhodeschroma.com/).

The ChromaTalk mailing list is available there. The details are here:

The ChromaTalk mailing list will be the best place for a request like
this as many Chroma owners pick up 'extra' parts to have on hand 'just
in case' - any one or more might be willing to free up some items
(especially smaller items like the key switches).

They don't often come up - but perhaps triggered by your question, I do
see that there's an I/O board currently listed on eBay too.

Congratulations on your Chroma purchase.
