Commodore/Amiga 570 and 690 CD-ROM Drives

The interfaces on the Amiga 570 and 690 are clearly unique to the Amiga 500. Unlike the other Amiga disk drives, which reside on the Amigas "Floppy" bus, these drives actually plug into the Amiga 500s expansion bus (where memory expansion, CPU upgrades, and other peripherals would also go).

The A690 and A570 were released in 1991 soon after the CDTV. Its purpose was actually to allow an Amiga 500 to emulate the CDTV unit by providing not only the necessary proprietary interface CD-ROM drive, but by also providing the CDTV ROM chips as well.

The difference between the 570 and 690 appears to be mostly in its name. The A690 was the earlier model, possibly a prototype, and seems to have appeared mostly in Denmark. It also has an onboard battery whose function isn't clear.
