I have an IBM PS/1 Consultant that I want to restore.
It is a desktop with a 486sx 25mhz. CPU, 8mb ram, 512mb HD, CDROM and Sound blaster 16.
Tseng e4000 VGA.
Model 2155 original config.
I downloaded the the recovery disk images form this IBM restore website.

Which I burned to CD and will install from.
My question is this computer does not have a Math-co processor.
I would like to add one but I am not sure as to which model CPU I need.
Here are some images of the motherboard.
