That sounds like you're just plain lucky :). All LC040-FPUless 040's I've seen have had "68LC040" stamped on the chip - and you have a nice happy FPU there I'd say! The one sure test is to download a benchmark prog such as speedometer - if it records your math speed as dozens of times faster than a Quadra 605 (the same as an LC475) then the FPU is there and working. dana -- unnaturally hosted on a Q605, http://www.danamania.com/ -- -- Quadlist is sponsored by <http://lowendmac.com/> and...
