> How did IBM convince Motorola to modify the 68000 and Intel to modify the 8087? Did IBMers do this work, or Intel and Motorola?
IBM had Nick Treddenick, the lead designer of the 68K do the work. His book "Microprocessor Logic Design" covers the development of the "Micro/370" in great detail, including flow charted microcode that looks remarkably similar to the flowcharts in Ken's article (though apparently Treddenick used flowcharts for the 68K microcode prior to moving to IBM. Regrettably I haven't actually read through my copy yet, so I can't give any further details.
Ken, if you see this I highly recommend tracking down a copy to read, I think it's right up your alley.
