@foone Persumably you go for a multicycle architecture, then you have this massive control state machine. Might as well turn that into microcode. Now that you've microcoded the control you can clean up the datapath a little, that'll let me regularlise the control store a little. Few more tweaks, oh look my microcode engine is now basically a Z80. Might as well embrace that and be able to use existing BASIC "microcode".

@foone wasn't this pun a key plot point in one of the James Bond films, perhaps "You only live twice"
