I'm thinking my IIgs could really be accented by one. Does anyone have any impressions of the FPE, and AE's card (FastMath?)? I'm afraid I don't know much about either. Address's and costs are also needed, and if anyone has one of either (right now I'm leaning towards the FPE) that they would like to part with I'd like to hear from you. Any relevent information welcome.

I have an FPE and it's very nice -- IF you really have a floating-point computational bottleneck. For most IIGS applications it has little effect. One nice thing about the FPE is that ORCA/C (and I think ORCA/ Pascal) can be told to generate code that directly accesses the FPE, instead of going through the SANE tools. A supplied "INIT" also plugs the FPE into the SANE toolkit, and there is also an executable module that can be called at run time from AppleSoft BASIC programs to plug the FPE in place of AppleSoft's slow (and buggy) floating-point support. I also found Innovative Systems staff to be helpful when I was having problems using mine (as it turned out, a TWGS ROM upgrade fixed the problems, as well as fixing TWGS DMA compatibility problems). I have no experience with other floating-point accelerators for the IIGS.
