Get Mini vMac or BasiliskII emulators, you can make a virtual 68k mac with more ram and disk space than was remotely feasible at the time, and can even cheat by artificially speeding them up to skip long render times 
Iāve even managed to get Mini vMac working on an ipad, tho I barely understand how.
(iām definitely in favour of getting an actual old mac too, but the real classic ones almost certainly will need daunting repair of dried up capacitors and exploded PRAM batteries, not to mention the problem of figuring out a workflow for getting files on and off them to modern computersā¦)
from about 3.15 in my recent stream you can hear an anachronistic noise collage I recently made using SoundEdit on an emulated Mac Plus. Edited from sound FX files found on shareware compilations, some of my childhood audio files, and some newly synthesised on other rudimentary mac audio abandonwares. 11000khz audio + digital hard clipping aplenty
Not sure this would have even been possible on a real Mac Plus, or at least would have required some waiting overnight for the timestretched parts to render
