They made some low-end models without CDs back then, including a Performa 630 and an LC 550 (which was sold only to schools). I have seen the LC 550 without a CD and I had to do a double-take at first--was it a CD-ROM-less LC 550 or a huge Color Classic? I'd imagine the 630 would look IIsi-like but a little more aerodynamic.

CD-ROMs were still considered somewhat optional equipment in 1994, especially on low-end machines. (The Quadra 605/LC475 comes to mind as a machine that didn't have a CD-ROM nor had room for one). CD-ROMs were still somewhat uncommon back then; I didn't even get a CD-ROM drive until Christmas 1994 because all the software I owned/wanted was on floppy (until I wanted A.D.A.M.)
