How rare are the IIGS ROM3 prototype chips?  Do they make the system worth any more?
I have one with a 341-0749.  The other Rom is a 342-0728, which I understand is not a prototype.

I'm guessing that if it's truly a prototype, then it's very rare.  I'm guessing there are a handful of Apple IIgs collectors out there who might pay you more for it.

The value of prototypes goes way up if they incorporate features not released in any shipping mass-produced product.
