This special 1x drive from Mitsumi had proprietary interface and a special way of loading the disc. It originally came with it's own ISA card, but it can be connected with old Soundcards if they have a Mitsumi CD-ROM connector (Soundblaster AWE32 CT2760 have this). Drivers can be found on the Soundblaster install discs or in this thread:

Specifications:
Data transfer: 150kb/sec
Access time: 340ms
Cache size: 64kb

My drive is manufactured in Feb. 1993, but drivers are from 1992. It was one of the first CD-ROM drives on the marked.

Norwegian advertisement from June 1993:

Does not read CD-R media so it is not very useful today. Still a nice curiosity.
