I need to find faster oscillators next :roll: only one I have is 75Mhz now.. And it does not even try to reset :(... Really need to find something like 55MHz , 60Mhz, 65Mhz.. or something like that..

Ok.
You need to beat us .. we've done 50MHz 68030 on our board.. so you are at 50MHz .. time to go higher :)

If only shipping was faster ... I still have three 64MHz 5V ones from my doubleST stuff. Not the square DIL-8 version though, but DIL-14

Actually the seller I bought from still have them, EU, fast shipping: https://www.ebay.com/itm/4x-64-MHz-Crys ... 4ad908842d

Thanks, I found a 64MHz just :D Though the CPU doesn't boot.. So likely around 50MHz is the limit.. maybe 55Mhz if there was such a thing..

Will try 52MHz then ;) Having problems finding any oscs at all , mouser all seem out of stock of everything :roll:


Actually my Falcon RSO modules start from about 50Mhz I think.. So will grab one of those tomorrow then I can go up in 1MHz steps easily :)

That's crazy. Well done! In terms of integer division, how would a 50mhz 68000 compare to TT's 32mhz 030?

Well 030 has a cache so will be faster for the same clock speed, plus 030 is more efficient core.. you would have to benchmark it with GB6 and see what it outputs with and without caches enabled.. Which would be useful anyway as we don't have a TT benchmark vs stock ST.. or Falcon in fact..
