[cctalk] Re: VAX 86x0 schematics

That looks a bit like a block diagram, sort of a conceptual level schematic as opposed to a detailed gate by gate schematic. It reminds me a bit of the "block diagram" manuals for the CDC 6600 supercomputer, which shows most of the logic modules and the buses interconnecting them, along with the relevant >clock pulses (more or less accurately).  But there are also the wiring diagrams, which are the actual fully completed schematics.  If you want to understand the machine, the block >diagrams are excellent; if you want to replicate it, they are not sufficient and the wiring diagrams are actually what you need.     paul
