With the help of a friend I finally have my Mac plus up and running. It has 4MB, a 500MB external HD, an CD Drive (an Apple CD150), and is running System 6.0.8. At first everything seemed to be going fine so I started loading some apps and games on the HD. Now suddenly I'm getting Unimplemented Instruction, Unimplemented Trap, and Address Error errors (and even the occasional No CoProcessor Installed error) when starting and exiting certain games and even when going into the Control Panel. Since I had no idea what caused the problem I took my Mac back to a base level and started over again installing everything one at a time and testing. Through trial and error I think I've determined that StuffIt Deluxe 4.01 is the culprit. It seems that after I install it and reboot things start to go wonky. :scrambled: I think it may have something to do with the extensions it's loading (there are two. One I think is for the MAGIC menu and I'm not sure what the other one does).

Does anyone know if StuffIt Deluxe 4.01 has a history of problems with 6.0.8 or maybe with the Mac Plus in general? I think I have a copy of StuffIt 1.5.3 that I can use instead, but obviously I'd like to use the latest version that works on my machine. I'll try and do more tests tonight and see if I can pin point the problem with certainty.
