I'm presently using a classicWB Lite environment on an A1200 68060 and its as solid as a rock, even running whdload demos. Not a single crash in weeks now, although I run it on average about 3-4 hours at a time to play games or do some DPaint/PPaint/Brilliance/Scala stuff. Runs like greased lightning too
Have to agree there. My A1200 is the same way, and it's loaded with a myriad of patches, custom ROM, PFS3 filesystem,
and an Apollo accelerator card.
The Zorro machines add lots of variables that can make it difficult to get a stable system. My A2000 was a nightmare to get running properly, right down to the cards having to be in "just the right" slots for everything to play nice. (I thought my PIV was failing (flickering lines and crashes), moved it down a slot and everything is perfect. The Ariadne 2 MUST be in one of the last two slots, etc.) In comparison, I can simply enjoy using the 1200 without spending hours hunting down strange/obscure faults.
