Bell & Howell Apple II update

You're thinking about a PC-CHIPS mobo, which came out a little later than the first "fast" '286 I got. The one I kept, however, was a later PC-CHIPS NEAT mobo, which used the IIT '287, which was designed from the gound up to run at the higher rates compatible with the CMOS parts produced by vendors like Harris. It was a mite tricky to operate, but once you had the tools and read the data sheets, it was quite impressive and quite solid. I found (and still find) the NEAT mobo to be VERY useful, having worked for a company that produced a software set that enabled one to load drivers in the adapter space and produced boards that mapped a modest amount of memory into that space, on 512K or 640K PC/AT's. One thing I did determine back then was that Win3.0 and later, v3.1x, ran faster on the '286 at a given clock rate than did a '386 at the same rate. I suppose this was at least in part because the first thing the software did was lie to the CPU and tell it, "OK ... you're a '286 now ..." By '91, folks were playing with their '486's.
