Sega Genesis · Add-on · 1992–1996
The Sega CD launched in North America on October 15, 1992, an add-on that plugs into the side of the Genesis and brings its own 12.5 MHz 68000, more memory and a CD drive. Discs held far more than cartridges, which made full-motion video games like Night Trap possible, and Sonic CD became its best seller at 1.5 million copies. The original Model 1 sits under the Genesis with a motorized front tray. The cheaper Model 2 followed in 1993 with a top-loading lid, built to sit beside the smaller Genesis. Sega sold 2.24 million worldwide before dropping it in 1996. Either model fits either Genesis with the right plates and cables, so check those parts come with it.
Before you plug it in
Should come with it
Check the listing photos against this list, and ask the seller about anything you can’t see. A missing piece should come off the price.
Drives that won't spin or read discs, units that freeze at the BIOS screen and damaged connector boards between the Sega CD and the Genesis are common Sega CD questions on iFixit. Sega's manual says to open the disc door only with the Open button, since working it by hand can make it malfunction.

Buying guide
We'd buy the Model 2 titled tested and working with its power supply at $250 delivered, just under the $257 median of the $210 to $340 band. There are at least 41 listed, nearly all Model 2s, and bare tested drives ask from $191 delivered, but the Sega CD needs its own adapter (DC 9V on the Model 2) plugged in alongside the Genesis one, so pick one with it or budget for it. Docking a Model 2 to a Model 1 Genesis also takes the extension spacer and the sound mixing cable, and none of these titles mention them. Drives that won't read discs and freezes at the BIOS screen are the usual faults, so ask for a video of a game disc booting. Skip the boxed Model 1 at $2,500, about ten times the median.
$190.70est. delivered
The lowest delivered Sega CD titled tested and working, a Model 2 at $191, but it's the drive alone. Add the Sega CD's own adapter, plus the spacer and mixing cable if your Genesis is a Model 1.
