For those who wonder when Motorola started producing 68LC040 processors without the errata that caused problems with software FPU emulation programs (such as SoftwareFPU and those built into versions of UNIX), here is the actual PCN right from Freescale: http://cache.freescale.com/files/shared/doc/pcn/PCNR00274.html It says that the transition began in mid-1995, so I can imagine the last 68k Macs, such as the PowerBook 190, having the fixed chips with the 2E71M mask that was awarded MC status (unlike the old chips with this bug that was only awarded XC status). Anybody have one of these?
