Also, pretty sure I got the actual datasheet around here somewhere. Me and Fujitsu part numbers MB86*, MB87*, MB88* and MB89* go a ways back. ICMiner.com claims to have it but is having trouble loading it right now. I think it's the same page, though: Chipdocs.com also has it: http://www.chipdocs.com/pndecoder/datasheets/FJTSU/MB89237AP.html?ReR=GG
But as you say (and according to the Fujitsu databook): you don't need it if you understand the Intel 8237A.
