Howdy all,
I recently acquired an IBM Eduquest 35, which besides a dying hard drive, works great and an Eduquest 40 planer\motherboard. To test the 40's board, I simply took out the 30's and put in the 40's in it's place. It also worked, which I was really happy to find out. I've read that you can add a 486\5x86 "Overdrive" chip into this slot and that it disables the soldered on 486 SX25, so you can use this to upgrade the processor. However, I've tried an AMD 5x86-133, an Intel 486 DX100, and a Cx486DX2-66 with no success. I insert the processor, turn the computer on, fans spin up and monitor powers up, and nothing. No image, no signs of life. Take the processor out of the upgrade socket, turn it on, and it springs to life.
My question is this, has anyone successfully used this socket to upgrade their CPU, and if so what was the processor you used?
Thank you!
Travis
