(Gee, I sound like an anti-drug commercial) 8087 (no dash) 5 Mhz 8087 - 1 10 Mhz 8087 - 2 8 Mhz 8087 - 3 5 Mhz and yes, you can usually push an 80287 up one notch (8 Mhz in 10 Mhz machine). With a heat sink you can sometimes go even further but you risk losing data, accuracy, and the co-processor chip. Hope this helps. -- Charles Lord cjl@ecsvax.UUCP Usenet Cary, NC cjl@ecsvax.BITNET Bitnet #include#include
