... all ACC´s and Autofolder programs off except of the nova driver?

The 68010 has a different stackframe than the 68000. NovaVDI hooks into exception vectors and would have to deal with this, maybe it doesn't know/care about the 010 but only the more common 020+ processors.

Nova VDI checks the longframe (0x59e) system variable to learn how to handle the stackframe. That variable is set correctly by TOS for the 68010, too. I could remember it wrong, but I think I ran the combination of Nova VDI and 68010 (with a Vofa 4000) for a while without issues.

EDIT: I just saw that the OP mentioned "Nova NVDI". My post above refers to Nova VDI.

I think there comes a message up when sta_vdi starts say 68000/68010 ...

Yes, it reads 68000/010 or something like that. Will take photos.

No, ACCs are not off. Didn’t know I had to disable these too.
Is this required with EmuTos as well?

Just a generally good way to troubleshoot issues. Disable all the things that you are not directly trying to get to work, and go from there, enabling one at a time.

There was one time I was trying to troubleshoot a motherboard that wouldn't post. I pulled everything out except one stick of RAM, and the CPU and it was a server board and had its own VGA out....
There was a possibility that it didn't ship with the newest BIOS which supported the processor I was trying, so even got a physical bios chip shipped to me by ASUS, since I didn't have an older CPU to try. Still no post...

Turned out I kept using the same stick of memory every time I kept moving things around.. pissed me off that is what it ended up being...

So yeah, start with the very basic stuff, no newdesk.inf, disable / rename all ACC files to ACX and disable all but the NVDI stuff in the AUTO folder. Did a lot of this while trying to get my TT going.

Yeah, I know, I do that for a living :)

XControl ist now disabled and MegaSTE completed boot. But apparently I’m now running on 8MHz instead of 16 since xcontrol.acc sets the speed (right?).
So the 68010 project goes back for a while.

I'm not certain if 16 MHz versions of the 68010 were ever built. The 1995 Motorola catalog, the last one that contained the 68010, only lists 8, 10 and 12 MHz versions. So does every other Motorola catalog I found. Presumably your 68010 does not like the overclocking to 16 MHz.

It reads MC68010FN25 on it.

Now that I’m searching I can’t find and sources. :(

As czietz says, there is no such thing as a MC68010FN25. You will only find these in Chinese shops. If it's actually an 8MHz 68010 then there's a good chance it wont't work correctly at 16MHz. The 12MHz 010 should though.

Try replacing it with your 68000, boot with XControl and set speed to 8MHz in the CPX. Then insert the 68010 again and boot with XControl. If it works now then you know that overclocking is the problem.

Boot with 8MHz was successful.

Some eBay sellers going to get a really bad rating.

Definitely a fake.
You would think it would take more effort/cost than it is worth to make fake labels on old CPUs. Unless these fakes were made a long time ago and they have been sitting around forever.

68k fakes (was: Re: Nova VME Bus Adapter Building Files ...)

Based on my personal (=i.e. not representative) statistic, about half of the 68k CPUs sold on eBay, Aliexpress, etc. are fake in the sense that they are relabeled and you don't know what you actually get. BTW, this is not restricted to Chinese sellers only, I've seen fakes from German, Spanish, ... sellers, too.

I also don't think these fakes were made a long time ago. You'll find MC68000s printed with a "date" code from 2019. (ROTFL! At least, these are very easy to spot.) I guess the 68k retro market is big enough that it pays flooding the marked with relabeled/faked CPUs.

Ha, I want a 7nm process building a 68000.

This also applies to other "retro" chips. I've received fake AY-3-8910's, fake EEPROM's, fake GAL's and also a fake Yamaha VDP V9958. The latter turned out to be a relabeled (could scratch the writing off with my fingernail) 8Mhz 68000. Fully working, now in use in one of my Mega ST's.
