Even earlier controllers were more integrated and usually had custom chip able to do DMA transfers.Interesting find I wonder how horribly slow it is 😀
I don't believe it is a full-blown SCSI implementation. It is more a proprietary interface to be used with Chinon CD-ROM drive. I do have a similar card, although mine is 8bit.
At that time those drives were capable of 150kB/s and multitasking wasn't a thing so speed or DMA didn't matter that much.
