Not strictly true. Lots and lots of WHDload slaves don't work well on 68000 based AMIGAs like unaccelerated A500/A600/A2000

Definitely recommend for an A4000 for most titles

The 060 chip isn't a BGA but has a very nasty surface mount socket. The PPC is a BGA. Whichever fix you had done kudos as both are very tricky replairs.

I've got an A4000CR which has a CR2335 coin battery fitted from the factory.
