What is the model of your motherboad and what CPU is installed? Or post a picture.

80487 is a socket for "math coprocessor" if you use a 486SX processor. With replacing/upgrading CPU you would first remove the old one and place a new one in the same socket and leave the 80487 empty.

I found this: http://www.cpu-world.com/CPUs/80487/the Amazon and this link both say 169 pin socket. I'll count the pins when I get home.

Check the MOBO first. In case you can install other CPUs it is easier / cheaper to install a 80486DX or Pentium Overdrive.

Good luck finding a 487. The last two I saw for sale were over a year apart. One was sealed in box for $199 and the other was loose for $99. For those prices you're better off getting a socket 3 motherboard and 486DX chip to put in it.

I beleive this is his motherboard http://stason.org/TULARC/pc/motherboards/P/PA … ml#.VHOTGsmmXN1

its a Packard Bell system. If you want to stay slow at 33mhz just get a 33mhz 486DX as suggested. as for mixing out the CPU, would an AMD 133mhz work in this machine, I assume so. It wouldnt give quite the power of the POD but I think its a cheaper option for good power.

Why not first trying to make that IDE connector before looking further.

Yeah, thats a good idea.

And if for some odd reason IDE won't work for you there's always SCSI.

Yep. Scsi cards are pretty cheap compared to IDE cards.

I'm seriously considering scsi right now.
