I can't do it just at the moment, but I'll do the test before the end of Monday (August 6... it's the 3rd today, and a long weekend here in Canada, so won't be near my rack until maybe Monday) and give you an answer one way or the other.
To be honest, I never bothered to run a program ROM diagnostic... or any of the diagnostics, actually. The unit worked beautifully as soon as I had it hooked up, and I haven't look back since.
On a peripherally related note, there are a couple of places around the net where you can still download sysex versions of the preset sets from the ROM cards that E-mu released for the Morpheus (they might also work in an UltraProteus, as they're basically the same unit with just a different base sound ROM... the Morpheus has 4Mb of more esoteric sounds intended to show off the morphing Z-plane filters, while the UltraProteus had 8Mb of sounds from the first generation Proteus modules [1, 2, and 3... Morpheus & UltraProteus started the second generation, which also included Planet Phatt, Orbit v1 and v2, Vintage Keys, and Carnival... third generation were the P2K and related family... there's others in there that I'm forgetting]... wait, why am I telling you all this, as you probably know most of it already?). Of course, having the actual cards is better, as you can access card presets without giving up anything from the first three RAM program banks. But the cards themselves are pretty rare today... there is one guy in the UK I think who sells compatible RAM cards on eBay, usually loaded with his own custom banks of presets and hyperpresets.
