Re: Has anyone fully decoded the X9000 memory mapping?


 

The data appears to be in RAM, but there's no clue about?how it's loaded.? As written it should be all zeros.

The schematic is also a bit suspect if you ask me, he's using just a plain jane 74LS245 running on?+3.3 as a level converter.? It might work, but it's certainly not "by the book".

I knew Teensy's were fast, but I didn't know they were 600 Mhz. If you go to the top project you see he also has a ton of emulators based on the Teensy which are CPU replacements.

Interesting...
