No can do guys.
Currently I don't have a functional Sonnett card.
But I am looking for a replacement.
My old card was a 7447.
I'm looking for a 7448.
Personally, I'd be willing to bet that David's 1.42 Mhz processor (with its better caches) is a fair match for a faster 7447.
A 7448 might have a slight edge.
I'd like to see.
What tests do you propose David?
