There is a Young Minds unit on Ebay right now, which was similar to the first unit I saw at sunsoft in about 1995 or so. This unit would have been from 13,000 to 50,000, depending on when you got hold of it. There was a kodak writer unit attached to this to do the writing. This particular unit seems to have a wide scsi under the connector marked "writer" so would most likely not be the same one as the one I encountered. Sunsoft could master the data and drive this unit via the SCSI port, and this in turn would write the cd. Overall the process took probably over 3 hours, but produced a cd which at the time was something that was pretty new, at least to me. I think there is was a Kodak unit recently, but I cannot find it now. they were packaged in a unit almost as big as this converted desktop. Jim 190046817654
