I do not want to go beyond the Amiga 2000HDs 9 megs of ram barrier (1 meg Chip and 8 megs Fast). To do so will make the system highly unstable.
On what exactly do you base this conclusion? "Professionals" say so?
If I can run powerful animation software on 9 megs then surely a CD burner program requires much less memory.
Burning CD-ROM is much more resource hungry than displaying or creating animations. You will be struggling with small buffers and slow CPU and bus.
