	Preliminary evaluation of our own AST 386/33 with a CMS 120 MB IDE
show less than "brilliant" performance. Indeed, both the Norton SI and
Columbia TESTDISK benchmarks show this combination running slower than my
NEC 386/20 (nothing special, by the way) running a WD1006V and CDC 94205-51
MFM. That holds whether I have software cache (Microsoft's SmartDrive)
enabled or disabled.
