Many early CD-ROM drives used on PCs were SCSI, and all of those drivers work on the XT class (8088/8086/V20) CPUs. There were a lot of devices from Future Domain, Trantor, and Adaptec. The Adaptec cards generally required a 16 bit bus but the software runs fine on machines with 8 bit slots. (I've used a lot of the Adaptec SCSI drivers paired with a Future Domain or Trantor ASPI driver.) The Future Domain cards and Trantor cards were well supported in XT class machines. And then there were the parallel port to SCSI devices (many sold by Adaptec).
Later/cheaper CD-ROMs came with proprietary IDE-like interfaces. And then finally things settled on ATAPI at the low end of the market. Just an opinion, but it's bad software design to assume that the presence or a peripheral implies a certain class of machine. The presence of a CD-ROM should not imply a 386 or better machine; it's orthogonal. -Mike
