Hard Disk Drive Types
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.
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.
Hard Disk Drive Types
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.
