Unless it is extremely high quality PC2100, most likely no. PC2100 is 266 MHz memory. Your machine runs memory at 333MHz. Even if the PC2100 is capable of running at 333MHz, it still may not work. The SPD information on the PC2100 most certainly instructs it to run at 266MHz. I don't know exactly how the m6809 BIOS will interpret this. With the lack of options, you can't tell if it is set to get memory timings from SPD, or just boot it to 333MHz no matter what the SPD info is.
