from our friends over at @BlueSCSI:

BlueSCSI Transfer Util is a new 68k Macintosh app (OS6-9) that allows you to pull & put files directly from an SD card, no emulator required to get OregonTrail on your Mac Plus HD image!
Give the Beta a try - let me know if you run into any issues: https://github.com/erichelgeson/BlueSCSI-Toolbox#bluescsi-transfer-utility
