It’s worth a shot. Don’t forget these Phase 5 / DCE accelerator cards are getting older now. You never know.
I have a slightly temperamental MK1. Took me a couple of months finding out after 9.5 and over cycle tests on ATK, that I had a failing RAM Simm. Since swapping that out, it’s been pretty stable. Have had the odd Guru still. So maybe it’s software or another SIMM about to fail.. 🤷🏻♂️ Arn’t Amigas great.. 😳🤣🤣
