Bro, there's only, like 4 (old) people that work at Unicomp that are basically riding this thing out until they retire. There's really not that far an e-mail can go. If there's any work that needs to be done outside of parts and tooling they already have set up, be prepared to pay. They are helpful folks, but they are not in the business for creating and marketing new products; their main business is replacing keyboards for older terminals, mainframes, etc. They took the business from Lexmark, which, IIRC, dropped SDL connectors before it spun off into Unicomp. There are some other folks here that can give you more information, but I wouldn't expect anything too ambitious from them. Your frustrations are recognized and noted. All sending that e-mail is going to do is piss them off or make them laugh at you.
