What glitch were you getting ? as I set CPUSPEED to 80mhz and I ran Quake on loop with no problems

Hmmm maybe you'll get 100Mhz then..

...No I tried it bud it locked up, just to add I have no capacitor on the 0603 pads next to the multiplier I took that off

The cap wont make much difference... might cause a crash eventually but not an instant one...

To sum up..

1. i can now boot DiagROM in 100Mhz mode. Although the CPU is really running at 14Mhz its being sampled at 200Mhz. This means the 200Mhz path is reliable.
2. The ram can be read/edited at this speed. The CPU goes up to 100Mhz for individual bus accesses.

Have not been able to run/execute code continuously at 100Mhz yet. I need to get DiagROM 1.2 into my A1200.

Put the new firmware on early this morning and it`s all good ..Quake been running on loop at 80mhz for good few hours now :)

Excellent. It’s tweaking now to get 100Mhz is working.

I’ve verified all the ringing is under control with my 500 MHz scope.

100Mhz 060 =O
500Mhz scope =O
=O =O =O

Well I left the TF1260 chugging away on soak from yesterday and it`s been on sold for 24 hours at 80mhz with no cooling what so ever and it`s still Quaking away :), awesome stuff..`Burnination` complete :)

Just to ADD if using a 68060/50 with MMU don`t forget to use the `NOMMU` switch, and perhaps the `NOAUTOVEC` switch , on problimatic non playing games/Demos, just add these to the `Tooltypes` in the demo/Game icon , something to bear in mind :)
Try the demo JesusonE`s Demo and it will crash without the above switches

Is that in the A1200 with keyboard & case in postion?

Yes bud the TF1260 now slots into the trapdoor with no problem , Steve has done a great job with the TF1260 form factor :)
