Hi trag,

Yes, I've modified Q605, not LC475, althoug I've put a jumper on the MB after I went to 40 MHz, which changed its gestalt ID to LC475.

At first I swapped resistors to go to 33MHz and afterwards I installed 40MHz oscillator, as per instructions on Marc Schrier's page.

I also changed MC88920 PLL to MC88916DW70 which I removed from that useless IIvx MB, installed "real' 40MHz MC68040 and put a heatsink on it. Heatsink came from Q700 that had damaged video output.

Cheers,
