I do have a similar upgrade in my Model 60 and can confirm without a FPU it is identified as a 486SX in Sysinfo. Mine despite running at 66MHz only scores around 29 points … it’s an IBM Cached Processor Upgrade card. There also appear to be 486SLC2 variants made by Hypertec (25/50MHz) which might even implement L2 cache!
