Running OS3.9 with a Vampire Board 500v2 in my Amiga 2000.
@SaludaLabs Your configuration will blow a mere 68030 out if the water. It is 20-50 times faster (depending on the benchmark) and has 128 megs of 32bit ram.
I have run 3.9 on a A3000 with 030 and 8meg of 32bit fast ram without any problems. With only 5megs of 32bit fast ram you may run out of 32bit ram from time to time, the 16 bit ram will keep things running, but the programs loaded into it will slow down.
