In the old days, .sit compression by Alladin Software's Stuffit program was the compression used by Mac users. It also handled .bin and .hqx compression schemes. At the same time, PC DOS/Windows used .zip and a few others.

You can get StuffIt and Stuffit Expander for the older Macs, it will be able to handle .sit, .bin, .hqx, .zip and many other compression formats. In the minimum you would need .sit, .bin, hqx, and .zip compression formats which Stuffit and Stuffit Expander handles.

RickyZhang, which version of Stuffit did you used? You may need to get an older version that will run on a 68K and not PowerPC.
