You can read and write GALs with no problem with your TL866II plus.

Unless a demo has been extensively tested on Mega STE then yes, there are differences compared to STE that can make a thing like border opening fail. I would not worry too much about it compared to the more "normal" problems. At least not yet.Dbug wrote: ↑Sat Apr 30, 2022 12:42 pm That one is probably for Troed, the resident fullscreen demo expert!: I also tried a recent demo from DHS/SMFX (The Art of Profanity) which was always failing after the first screen, now I've been able to run it twice in a row from start to finish, there are some occasional top-border fullscreen fails, but at least it ran completely without crashing.

It should use almost of all free memory. If there are problems with that, it has nothing to do with the VME bus.
I gave up with those Atmel GALs. No programmer I tried would program the powerdown pin correctly. Might work for others or just don't use pin4 IIRC and you can. They tormented me during my STE booster stuff for ages.stephen_usher wrote: ↑Tue May 03, 2022 9:19 pm Forget the obsolete Lattice GALs which aren't manufactured any more, get the Atmel ones, ATF20V8B
