The flash for the MB? Don't mean for the 060 upgrade.
Good to know it will still boot in 040 mode.

Yes, that's the early information I read about the flash. Michael said there is no way to tell what package is on the board. I have the box to do so, guess then I could check file sizes.

Peter, have you tried running the CPU (060) 3x the bus speed? We know the 060 easily can be over clocked to say 60 to 75mHz.. I guess then more IC's should be reviewed.

Was thinking of daisy chaining two

The 926 can also output an inverted clock, which could be tested with the Falcon SDMA issues. It keeps a very tight spec on all clock outputs. Going to test this idea soon.

My hardware skills don't stretch that far.

I am not 100% exactly what flavour of 68060 I have in the Milan.

Still working in my Afterburner Falcon. It's had so many bus accelerators lot of rework required.

Purchased a pre-built Amiga adapter for the 060 since this thread started.
Also sent one of the DIY 060 Amiga to Neurotoxic, more 060 Mailan's the merrier :)
Soon!
