Processor Chips

If you have the 4SX/33 system, you can install an Intel OverDrive processor (ODP486-33) or a 487SX/33 microprocessor (with built-in math coprocessor) on the main system board. Installing an OverDrive processor effectively doubles the internal clock speed of the computer’s microprocessor; future OverDrive processors may be available for the 4DX2/50 and 4DX2/66 systems.

Hard Disk Drive Types

The table below lists types of hard disk drives you can use in the computer. Check this table and your hard disk manual to find the correct type number(s) for the hard disk drive(s) installed in the computer. You need to enter the type number(s) when you set the hard disk drive configuration in the SETUP program.

SIMM Installation

There are two SIMM sockets on the main system board. To increase the amount of memory in the computer up to 128MB, you can install 36-bit, fast-page mode SIMMs that operate at an access speed of 70 ns or faster, with a capacity of 1MB, 4MB, 16MB, or 64MB.

The following table shows the possible SIMM configurations; do not install memory in any other configuration. Make sure that both SIMMs operate at the same speed. There is 4MB of memory soldered onto the main system board.
