I don't want to rehash a lot of information about V20 and V30 NEC CPU's but I do have a few questions that I need answered. I have an 8088-2 (8MHz) machine (Leading Edge Model D) that also has an 8087-2 coprocessor. I would like to replace the 8088-2 with a V20 but which one? NEC makes 3 different V20's, a 5MHz for the 8088, a 8MHz for the 8088 or 8088-2, and a 10MHz for the 8088 or 8088-2. My questions are.... 1) Can I put the 10MHz V20 in may machine and still have it work with my 8087-2 coprocessor? 2) If I use the 8MHz V20 how much faster will my system be compared to the 8088-2? The book I have says that the 8087-1 coprocessor is for an 8086 running at 10 MHz or less but they do not have one listed for an 8088 running at 10MHz or less. 3) I do not want to give up my 8087-2 coprocessor but I want to maximize my CPU speed. Which V20 should I use? Any help would be greatly appreciated :-) Please post any responses so that all may share the information. Thanks, Vicky
