Re-reading my earlier message, I think I had the wrong empasis. I meant "Almost certainly *some* kit shipped without an FPU" not that all non-computer kit shipped without an FPU. For example, the DECnis started out using culled SOCs: no guarantee that the FPU worked and no guarantee that more than (I think) five of the cache banks were good. This was a way of using up SOCs that were no good for computer systems. I think I remember reading in one of the DTJs that some of the VT1xxx and/or VTX systems had no FPU. Antonio arcarlini(a)iee.org
