That sounds great. More flexibility for the systems!
Soon I'll be able to do something like
Code
mess at386 -isa1 gus -isa2 et4000 -isa3 aha1542 -isa4 ne2000
and dual-boot Linux 1.x and DOS (for some oldschool demos) on it... :-D

Configuring the CD-ROMs/HDDs for "plug-in" SCSI controllers will probably be a PITA though. Unless the frontends catch up.

Oh and I think the GUS also had a SCSI controller included where you can attach a CD ROM. Or was the the ProAudio Spectum?
