Finally, are these LC060's of any value to Amiga users
Sure! If they are cheap.
An LC060 still blows away a lame 030 or 020!
How much are these LC060s selling for?
or does AmigaOS expect and require an FPU in an 68060 in order to function?
Not required.
Did these chips have an MMU?
BTW: u can never trust the markings of any 060 100%. You must
always test the chip to see if it really has an MMU or FPU.
For example: The 060 in my A1200 has markings that indicate no MMU.
Yet the chip
really does have a working mmu!For some ppl (like me) a MMU is more valuable than an FPU.
