The fastest When clonemakers claim "15Mhz", they invariably mean "throughput", as given by some package like Norton Utils or the Landmark benchmark; the machine is probably 8 or 10Mhz with a V20 and 0 wait states. Aside: I think this is scuzzy! Ads should state real clock speed! Anyway, an 8087-1 or -2 should then work. (Also: if the machine's 'turbo' mode is switchable, a 5Mhz 8087-3 might even work at the slower speed.)
