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.

    I found a doc on the wayback machine that says that the ram is SRAM? have you found any chips that work? I'm asking for me It's the last upgrade needed for my Tandy 2500SX/20
