Few things are more unrealistic than porting SMSQ/E to the ARM architecture. So I never even start thinking of it. And personally I like the beauty of the 68K architecture and assembler language.
Well, thank you for putting so much thought into it before sh!tt!ng all over it. I wonder how far Sinclair would have gone if every time he had an idea, the first thing he heard was "that's unrealistic"... It's a big job. Maybe bigger than the community could ever do. It is *technically* feasible. There is just a manpower problem. But hey, thanks for putting so much thought into it.

I wouldn't call it a solution
, but wishful thinking. At least wishful thinking that is more realistic than a port to ARM, and multicore is well suited for FPGA.
What do you think the whole point of Goldfire was? That Coldfire core was a 68060 with multiprocessing logic.
Or what if you have a $2 68SEC000 running the QL and IO, and a 68060 running SMSQ/E with its own video system, and a small dual port IO area shared between them? The '000 would be a helper processor doing IO for the '060. Feasible? Yes! Reasonable? Yes! Cheaper than an FPGA? In manufacturing cost about the same, in design cost far cheaper. Have the '000 run background tasks that don't require screen space? SURE! Have the '060 do the heavy lifting? GREAT!
It the CPUs were symmetrical? Even better!

I disagree here. The 68060 is significantly faster per clock, consumes much less power, runs at a useful logic voltage.
Did you fall out of the wrong side of the bed, land on lego, break your coffee maker then decide it would be good to post on QL Forum?
*grins* It's ok, I forgive you. We all have bad days sometimes.
