Does anyone know if an AT90S1200 can be used in place of an AT90S2313. The pinout looks the same but will the code work?

Have you compared their datasheet?
One main difference is 2313 has RAM, 1200 only have hardware stack, only 3 level deep.
According to the datasheets, among the things that the 2313 has which the 1200 doesn't are:
128B EEPROM (1200 only has 64B)
2K Flash (1200 only has 1K)
Two timers (1200 only has one)
Two external interrupts (1200 only has one)
X and Y registers (1200 only has Z)
Additional instructions and addressing modes (e.g. ld r0,Z+)
Read access to flash from program (via LPM instruction)
But the 1200 does have an on-chip oscillator.
