Let me quote a recent exchange that I had with another member on MorphZone.
"In terms of Dhrystone an e600 core above 1.72 GHz would outperform a 1.8 GHz PA6T core"
I want you to keep in mind that the person who posted that thinks very highly of the PA6T (the processor in the X1000).
But the hardware we're running already comes close to the above mentioned speed and future hardware could run that fast or faster.
So, for a fraction of the cost, I can get hardware that performs almost as well as the X1000 now and upgrade later to even better hardware later.
And the Natami developers have already nixed the idea of an add on card.
If you like native 68X systems so much, why not wait and get a Natami?
