That's an excellent book. Even though people generally don't design using 2900-series bit slice components any more, I still recommend it to CPU designers as there is still a lot of good information of general applicability.

They had great information on very wide control words. I have forgotten what the assembler was but I remember having to create the code using an 8080 macro assembler for a class I took. Great fun! |

I'm familiar with two bitslice designs to emulate the 8080, one by AMD using the 2900 series, and one by Signetics using the 3001/3002 (which they second-sourced from Intel): http://www.bitsavers.org/pdf/amd/AMPUB-064_8080sim.pdf http://www.bitsavers.org/pdf/signetics/Signetics8080emulMan.pdf One of the Signetics boards sold on eBay a few years ago, but I didn't see it until too late.

It was an AMD publication in a small paperback booklet. At one time I had 3 or 4 of these booklets on different topics but it was so long ago I just can't remember the details. I got far too ruthless with my library when I moved a year or so back. > > I'm familiar with two bitslice designs to emulate the 8080, one by > AMD using the 2900 series, and one by Signetics using the 3001/3002 > (which they second-sourced from Intel): > > http://www.bitsavers.org/pdf/amd/AMPUB-064_8080sim.pdf > http://www.bitsavers.org/pdf/signetics/Signetics8080emulMan.pdf > > One of the Signetics boards sold on eBay a few years ago, but I > didn't see it until too late. It is a good thing that bitsavers is out there. They have some interesting archives. > > Eric |
