Computer Specifications

CPU and Memory

32-bit CPU

System speed

4SX/33: Intel® i486SX, 33 MHz microprocessor; can be replaced with optional 487SX/33 or ODP486-33 OverDrive™ processor

4DX2/50: Intel i486DX2, 50 MHz microprocessor; supports future Intel OverDrive processor

4DX2/66: Intel i486DX2, 66 MHz microprocessor; supports future Intel OverDrive processor

High, low, and automatic speeds available; high speed is CPU-dependent (33, 50, or 66 MHz), low speed is simulated 8 MHz, automatic speed switches from high to low only for diskette drive access; speed selection through SETUP, keyboard command, or ESPEED program; 0 wait state memory access at high speed
