Well good luck then. Just ordered myself some Atmel Gals as my PAK still doesn't work and I know everything else on it does.

Hope you have better luck that I have so far.

Now to see if the PLD is found.. then onto doing some simple test firmware (pinout is different than last build so have to do some tweaked firmware :roll: )

Looking great. Isn't that already faster than the 40mhz v1.5 ste booster that I have? Looking forward to seeing 50mhz

Its probably a bit faster yes. Though this isn't running with the blitter, so its not exactly a fair comparison to the STE booster speeds on this benchmark... Will add the blitter and re-test once I have 50MHz running again.

And once you're finished I can break it by putting it in my Mega :lol:

Oddly (again) TOS104 works at 50MHz but TOS206 does not...

.. and yet, TOS206 works at 40MHz.. bizzare...

Also my highest score of 506% on int-div!

Not been able to figure out TOS206 not working at 50MHz, but some progress made at least today!

Oddly I still get that I7 bus error thing with the diagnostic cartridge :shrug:

Keep up the good work that elusive stable 50MHz will be there soon.

I don't get the I7 error when running 8MHz...

I wonder if when the CPU sees BERR from the GLUE, it does whatever it normally does to fast, then re-reads BERR and locks up totally.. Or for some reason ST_DTACK is still low when GLUE issues BERR and it confuses the CPU... But that would be tricky to figure out.. I guess I will have to read up on how BERR all works again..
