I have burned CDs on a 68010 A500 with 2MB RAM.
Use a good SCSI controller with DMA and you can pull off 2x burns.
IE. don't use eg. Supra, Golem, but instead use A590, GVP HD8+, or some other good controller.
Oh yes and the CD writing software is very slow on a 68000 machine. If you enjoy watching the machine draw stuff on your screen, go ahead.. :-)
