(1) A 486SX-compatible CPU from Cyrix that was pin compatible with the 386SX, had a 1K cache and used a 16-bit bus. It provided an upgrade path for 386SXs.
Standard features of this sub-system include a 486SLC 33MHz a processor, 80 or 120MB removable hard drive, 4-20 MB RAM, and a 64 level grey scale display (VGA 640x480).
In 1994 Cyrix transitioned its product mix from entry level lines such as the 486SLC and 486DLC microprocessors and math coprocessors to primarily 486DX and 486DX2 microprocessors.
