AMD 2900 Family Bible - supports current IP

Intro to Bit Slice

Lecture Monograph updated

The AMD 2900 Family (Am2900) Bit-Slice and other devices were supported by a number of high-level application notes. (Generated by the AMD Application Staff.)

The popular 2900 family was presented in hundreds of seminars to a world-wide audience from 1977 thru the early 90s. It has not be produced by AMD for well over a decade (if not two) but it lives still as IP blocks. This is soft IP (RTL code - mostly Verilog). Designs are still being maintained and new designs using IP are still being conceived. Here are some documents saved from the dust. Controllers are still designed everyday. What a waste to constantly re-invent the wheel!

ED2900A Seminar Introduction to Designing with the AM2900 Family of Microprogrammable Bipolar Devices Written/Taught by D. E. White (1981): This was the basis of the textbook Bit-Slice Design: Controllers and ALUs which was done with full backing from AMD. They handed it out to customers.

A note on vintage material - the seminar above was written before the creation of WORD, laser-printers, or any of the tools so readily available today. The pages were copied, assembled (punched pages jam a copier) and then scanned to PDF in sections. They are pretty much as they were. We had two fonts - Impact and Courier. Impact printers (Daisywheel or the Spinwriter), and no drawing tools. There was no sp el-check (we had a 3rd party tool that tried). [It was first written in 1979.] We added illustrations with typing or we copied from data books and pasted them onto the camera-ready copy. White tape, glue and white-out were standard tools.

The formal ap notes were actually type-set and the drawings done by an illustrator. We laugh today - when FrameMaker, QuarkXpress, InDesign, Illustrator, screen-capture, file-transfer, VISIO, Photoshop and PDF are available and printing is done in color or B&W with a laser printer we have to constantly tell IT to tone down - we don't need 1200dpi!

The ED2900A and ED2900B Seminars used a common Study Guide/Teacher's Manual:
