Anybody know where one can obtain the Motorola Semiconductor ref. for the 68230 or at least get a book of some kind that has a chapter in it on the 68230? I am upgrading to a new computer that had a 6821 PIA in it, and now I will have to re-write some driver stuff to handle the 68230 instead of the 6821. Thanx in advance, Russell E Hoffman Carnegie Mellon University rh2y+@andrew.cmu.edu rh2y@unix2.andrew.cmu.edu

This manual can be obtained from your local Motorola Semiconductor Sales Office or through the Motorola Literature Distriibution Center, Tempe, Az, Phone 602-994-6561.

What you want to ask for is the "Advance Information data for the 68230 PI/T". Their 68000 uP products book has a few pages with electrical specifications, timing diagrams, and brief register summary. The 68230 is *such* a complex chip, though, that you really need the advance information book with detailed register descriptions. A really neat chip. Too bad Intel doesn't have anything for 80xxx processors more complex than a 8255 ..... Good luck! -- Mark A.
