Re: An Overdrive processor for the 6502

This is what the Solidisk 4meg and 256 boards did BITD. 4MHz CPU with some "fast" RAM plugged in the 6502 socket. I have on my dev list to do a modern version of this, I just haven't got round to it. Ooh, so that's what it does. I saved a beeb fitted with a 4meg from being thrown away a c...

Re: Electron ULA to RAM timing

A quick follow-on question about this... If the Electron had an additional 4 x 1bit RAM chips to give 8bit access to 64K of memory, would this have allowed the CPU to run constantly at 2Mhz alongside the ULA without contention (even in Modes 0-2)? And would this have given the same performance as a...

Re: Apple goes ARM

Actually, I don't think they are using ARM processor designs -- they are just using the AArch64 instruction set. I think Apple's processor design owes more to PA Semi (whom apple bought to everyone's surprise in 2008 -- they made PowerPC chips and Apple had switched to Intel) than it does to ARM… S...

What did Apple do with the stake it in ARM back when it was formed by Acorn, Apple and VLSI? I guess they probably sold it sometime after the Newton ceased to be produced.

Still, the ARM didn't do too badly. With Apple now going ARM, it's funny how things have come full circle.

With hindsight one of the few good things Amstrad did on some of its earlier PC clones (PC2000 series) was to use AA batteries stored in the top of the case instead of batteries on the motherboard.
