    there is a discontinue chip (AT90S8185) that I have, it doesn't come with an internal oscillator, I was wondering if I can get it going with a RC/RCL oscillator circuit? thanks.

    I am new to MCU so this is a learning experiment for me :)

    Are you planning on using the UART?
    Does the chip have two XTAL pins? If so use an external XTAL.
    Otherwise use a XTAL oscillator module.

    yes, there is a XTAL pin, not planing to use UART
