Re: Questions to Rodolphe (68060)

The 68060 used on Hades was the mask rev.1 (1F43G) and is not able to run more than 72 MHz.
Hades was set with 60 MHz and HALF speed bus mode --> bus was at 30 MHz and so DRAM (and EDO DDRAM for those that have the updated DRAM controller).
It seems some HADES were at 64 MHz (bus 32)...

CT60 has a fullbus mode (= the CPU clock) and SDRAM at full clock too.
Very important difference with HADES.

The last Mask (rev.6) 71E41J is able to run at more than 100 MHz (record is 107 on a CT60).
