ST xfer question

I recently acquired again the 520 ST I had in my youth, along with a SF354. I know the drive stinks, but its what I had and what I wanted to get again. I wont really be using the system other than to demonstrate it. That being said, it has TOS 1.4. I do not have any software for it period. I do have ST softwareo on my Mac. i plan on getting an UltraSatan or similar in the future but its not a priority.

Question. How can i get software to the ST in the interim? I do have sn SX212 modem, but again no software. So Im thinking I have to get my hands on a terminal software disk or cartridge. Ideas?
