RAM *shouldn't* be a issue... I've run both my boards with Alliance and Winbond. Now using a external blitter motherboard..

But something is amiss because like that buffer tweak, I had issues, then now I don't. But now you do... It's like something is starting up somewhere in a random state or something every time.

@Badwolf Are you 100% sure it is a TTram issue? Original TOS206 is still basically a 68000 system which doesn't understand caches. Might be worth turning cache off in the desktop menu and just ruling that out next...

I can send you this board next week if it helps? and even the STE motherboard if it helps?

Yeah might as well send both .. It would help if it could come early next week as I'm going to be distracted with the DFB1X builds soon...

Ok, please PM me your address again and I'll see if I can get it collected on Monday.

No I'm not sure at all as I've no way of turning TT-RAM off for a like-for-like comparison. I can't just disable caches on the desktop as these never see the desktop.

Well, unless I build a non-TTRAM detecting version of EmuTOS 1.3 and burn that to to a ROM chip so I can flip the jumper, I suppose.

Let's see what happens once I'm on the new chip as then I can at least try current firmwares.

@Badwolf Ill upload a "No TTram" build shortly, but its half mutated with my current chaos. I had to get my Falcon on my table now, so can't test it unfortunately.

For the 288? Grand. Will give it a crack if I get the "proper" test firmware booting first.
