Something seems off to me about this specification. It's too ambitious for 1982 as a successor to the 6502 that would be realizable at a marketable price point. I can't really put my finger on it, but it somehow feels like it was written recently. The "Review of the MCS65E4 Project Goals" reads like a hobby project pitch as opposed to an internal engineering document. I've read docs and specs from this era and this doesn't fit.
I don't' want to troll, and this may be 100% genuine, but can anyone vouch for the authenticity of this doc?
This is from after CBM bought them. I don't know how different things were from the MOS side, but stories from the CBM engineers during the Jack Tramiel days did leave the impression that they could pretty much do whatever they want feature-wise and integrate it into the product that Jack wanted, as long as time & budget was met; there was little micromanagement.
CBM also considered rolling out test silicon to be very cheap, because they owned MOS, and apparently prototyped chips commonly. There's some interesting tales here:
