Probably after the era of PC/XT upgrades, the 386SLC had the clock speeds and on-die cache that made close to the DX. I really enjoyed my time developing on OS/2 1.2 and later 1.3 with the IBM intern-developed VESA SVGA driver. It was multitasking that really worked. My first PC was a clone 386DX with socketed cache chips, 8MB RAM, and 11 MHz overclocked ISA bus to make the video updates faster. My next PC was a PS/2 Model 77 running OS/2 (and later Win NT). It was so hard finding an MCA SoundBlaster-compatible card (by Piper Research) so I could play Doom.
