MrMobius: Is strikes me that it's a very strange thing to add a 24-bit option on what's essentially still an 8-bit architecture, I wonder how useful that was to anyone

<MrMobius>
maybe they had it there for address calculations anyway so just reusing it

<veltas>
I think that must be it

<MrMobius>
the original z80 had a 4 bit accumulator iirc so 8 bit adds happened in chunks

Typical 8-bit processors of the day were 1MHz to 2MHz, the Z80 you'd often see clocked higher at e.g. 3.5MHz in ZX Spectrum. I don't really know why or how they achieved that, but it makes up for the relatively long pipeline a bit

I know that generally that's about the rate that things like open-drain signalling breaks down, it seems that a few tricks were needed to go beyond around 4MHz reliably

Sure it's an interesting bit of history to someone who understands electronics better than me

just browsing ebay, wondered if somebody here might find this interesting:
