We could have 1st SMT provide this service (as they've done various Acorn-upgrades in the past). I'll check out the costs - I expect it'll be something around 70 quid to cover a new chip, swapping and postage. > > (BTW, what's the problem with the old StrongARMs?

IIRC it was something to do with data aborts on a 4K page boundary. Phil, didn't you work out some scheme so that the compiler could try and make sure this didn't happen? Of course that means fixing the compiler and re-compiling everything with this option, which isn't very practical, but would provide a solution. Or did you decide that in fact it wasn't going to work?
