Not at the moment, I want to finish off/clean up a few things first. Yes, there was a Swedish version of the Microbee and they were popular with schools here in Australia so I'm not surprised to hear you had them in Swedish schools too.
As a software developer I've always had a vague understanding of how computer hardware works, but after building fpgabee I have much deeper understanding. eg 1: I always knew what a VGA controller did, but had know idea how. Now that I've actually built one (albeit in code) it's pretty clear to me now. eg 2: I never really understood why hardware can't be just clocked to higher and higher frequencies... but now I totally get it.
Interesting idea! Though as I understand it, the limiting factor atm would be that FPGA cores are considerably slower than real silicon. So even if you had a huge FPGA, loading an identical circuit to a modern processor would not be anywhere near as fast.
