The 68881/68882 are always optional (they are separate FPUs). 68881/68881 can only be used together with the 68020/68030. The 68000 can't use the 68881 like the 68020/68030 (must be adresses like a separate I/O device). For the 68040 and 68060 the situation is different. There are several CPU configurations available. In a Milan you can install a 68040 with or without a FPU. The full processor version is named 68RC040, the version without the FPU is named 68LC040. Same for the 68060. If I remember correctly there are also CPU versions without the MMU (but such CPUs can't be used anyway I think). For Milan/Hades you can use both CPU versions (with/without FPU). For Afterburner too. For ct60 I don't know (I expect the CPU without FPU can be used too). > Is there some CPU where the FPU is always present ? Not for the 68000 series :-) Regards, Frank -- ATARI FALCON 060 // MILAN 060 ----------------------------- http://sparemint.org/ e-Mail: fnaumann@boerde.de
