Doomy,
There is a version of AsimCDFS that will run under 1.3. I have it packed away somewhere. Haven't seen it in years. A 3000 may be the way to go for you. If you get one with the original ROMs (not 2.04) the early boot screen gave you an option of soft kicking into 1.3 or 2.x. Of course a rom switcher for your 2000 would do the same trick.
Your 2000's may be built like a tank but a 3000 may have been the best Amiga ever built! :-D
BTW Doomster I own 1 1000 in pieces now, 1 500, 6 2000's, 2 3000d's, 3 4000d's, and 1 4000t. The 4000t and 3000's are much better machines than the 2000's although the 2000's do put out a very good video signal out of their genlocks.
