I have to mention by the way, that a real working frequency for TurboKing and Simultano is 2,5 Mhz and not 5 - because its generated through NEC uPD78310/312 onboard controller (that 64-pin monster near 6502 cpu).
Are you sure about this? I have empirically checked, on my TurboKing, that the system clock signal on pin37 of 6502 is 5Mhz.
BTW, this computer is great! I had no idea of its existence. Thank you very much for sharing all this information. I will follow your progress closely...
