notes Notes

Model 57 has 2 additional 16-bit MCA slots in the riser. The motherboards are the same.

The 486BL3 75MHz CPU is based on the 386DX platform, however it can operate in 16bit 386sx mode. This is how it is operating in this system, with a performance penalty. Additionally its cache runs at 25MHz so it is further hampered.
