6. Something else
Get your 1240 upgraded to an 80MHz 1260. If it is an Apollo get a second SIMM socket too. Will cost far less than $300 and it will make it fly. Plus it opens a world of 68060 only games & demos.
Get the SCSI module for your 1240 and an SCSI->IDE adapter ($30) this will unload the CPU for disk activity and make it a whole heap faster.
If you don't already use SFS switch to it or buy PFS3 either one will make hard disk access MUCH faster than standard FFS.
