Rescued LC 475 CPU Chip ID
I recently rescured an LC475 box on its way to the recycler. Its provenance is unknown. It has 4M+16M memory, 512K VRAM, and the standard manual-inject HD floppy and 160M hard drive. What I'm not sure about is the CPU. Stock LC475s are supposed to have a 25MHz 68LC040 CPU (no FPU). The chip in this box is labeled XC68040RC25M. MacCheck says that it has a 68040 processor at 25MHz with a built-in 040 co-processor. So, my question is whether this a 68LC040 in a clever disguise or a real 68040.

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...

Thanks for the information about 040s and the speedometer link. I'll be checking it out as soon as I can get the system on the net.
