Is it possible to have 040 and 68882 on the coprocessor board ? Recent discussion in comp.sys.next disappointed me because 30+ 68882 25MHz beats 040 25MHz in several benchmarks due to 040's emulatation of trigonomic, logarithm, and exponential functions through trap mechanism. This is a performance setback of 040 in 680x0 family, and I am wondering if this could be improved by simply doubling clock speed to 50MHz. (Some of them are reportedly 200% slower than those of FPU). I am happy if could beef up my A3000 with 040+FPU while NeXTstation serves it as a GUI box. >This _is_ the main part which bothers me about getting an A3000. >That I'll be buying the machine and then (assumably) shortly afterwards >getting a CPU upgrade to an 040 .. > On the other hand this is the very reason why I opted for A3000/16. I know the possibility of 040 and 030/25MHz working together, but I have no idea when such AmigaOS/MP ROM is available :) >-- ><- David Herron, an MMDF & WIN/MHS guy, ><- Formerly: David Herron -- NonResident E-Mail Hack ><- ><- MS-DOS ...
