Intel486DX, Intel486DX2 or OverDrive processor with a
maximum external clock speed of 33MHz.
Any other Intel processor using the same pinout as one of
these processors could also be installed, subject to the

Note
This table lists the processors supported by the
motherboard. There is no guarantee that any particular
upgrade processor will be available at any given time.
Depending on the processor type fitted in your system unit
the processor socket may already be occupied. Before
installing the upgrade processor you must first check
whether the processor socket is occupied, and if it is,
remove the existing processor. Instructions on locating the
socket and removing a processor are given below.
1. Power the system down.
2. Take suitable anti-static precautions and remove the
system unit cover.
If you are unfamiliar with Apricot's recommended
anti-static precautions and/or the process of
removing the system unit cover refer to your
Owner's Handbook .
