Hi
I have an A1200 desktop with B1260, and an A1200T with BPPC 040+BVision. I also have a B1230/50 with FPU installed (I have the mk2 version not the ubiquitous mk4 everyone else seems to have) in an antistatic bag since getting the B1260.
In my experience, as long as you install the correct/best 060 libraries you don't seem to get any real compatibility issues versus the 1230. I use the 060 libraries from the MMUlib package (
http://www.aminet.net/package/until/libs/MMULib), along with a speedup patch MuRedox (
http://www.aminet.net/package/util/boot/MuRedox). I'd also recommend using the following patches on any expanded AGA system with an FPU - FBlit/Ftext and BlazeWCP.
The only game I've had any problems with on the 1260 versus the 1230 is the CD32 version of Super Stardust - I get very minor graphical glitches, but the game is still playable. 99% of whdload stuff I try works, and those that don't usually didn't work on the 1230 either, probably because there are corrupted files etc. In overall performance with Workbench etc, it's MUCH faster especially if you use the patches.
Also, games like the Duke Nukem 3D port are more than playable on 060/AGA using the afore mentioned libs/patches - which is nice :-)
The BPPC040 though is different. Its more of a pain to setup tbh, and I'm not sure the benefits of PPC+ the b-vision outway the speed and compatibility benefits of the B1260 AGA machine. Also, as I don't currently have a monitor that has 2 inputs, or supports both native AGA screen modes as well as the RTG screen modes, I have to use two monitors which is a royal pain in the arse as far as I'm concerned.
That being said, I'm in the middle of re-building the BPPC machine from the ground up with the emphasis being on the PPC and B-Vision graphics card side of things as opposed to the whdload/AGA side of things. I'm also going to see if I can obtain a cheap small LCD TV (Wife permitting) with multiple inputs that will work with both the AGA and BVision card's output, so we'll see if that improves things a bit.
I don't think I'd opt for the BPPC setup over either the B1260 OR B1230 if I was purely using it for whdload/gaming in general. Also, I doubt there would be any real benefits to PPC on an AGA only system, as most of the high end PPC games/apps require a graphics card. I don't think I'd opt for an '040 in a desktop case either because of the potential cooling issues.
Anyway, thats my 2pence, sorry if it sent anyone to sleep ;-)
