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:

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?
