Thread: Tandy 2500 SX/20 and Tandy 4825 SX restoration thread

    Could you provide a little more detail about the CPU you upgraded to?

    The manual of my 4825 SX says you can only upgrade to a 486DX2, were you able to get a DX4 working? Is your AMD 3V or 5V?

    Thanks for the write up!

    Thanks to acadiel for this link showing the Evergreen CPU upgrade he was talking about.

    I had no idea these things existed!

    acadiel,

    I was just wondering. Have you had any luck with the Video DRAM?

    I'm looking to soup up my 2500 SX/20. I see the same 256kx16 on ebay, but not anything else.

    Nope, I haven't found any zip chips that work yet. Those things are fun to plug in as well.
