No it doesn't. The CD unit that works with the Model 1 Genny attaches underneath and the CD unit that works with the Model 2 Genny attaches to the side of it. Now there is a base that the Model 2 Genny sits on but this is NOT the CD unit... it is a base. And I am positive that the 2 units are not interchangeable with the other Model units, i.e. Model 1 Genny will not attach to the Model 2 CD system and vice versa.
Not exactly correct.
The original Model 1 Genesis will work with either model Sega CD unit just fine.
The original front loading model 1 SegaCD that the Model 1 Genesis sat on top of still connected to the Genny's side port via a right angle stick-up connector on the right side of the CD unit. It had a 1/8" stereo audo-in jack that connected to the Genesis's headphone jack to allow the Genny's sound to be passed through the CD unit.
The second top-loading model 2 SegaCD came with a base extension to screw on to the base section to give it the same footprint as an original Genesis. It also had a 1/8" stereo audio-in jack to connect to a model 1 Genesis's headphone jack.
Both CD units came with the 1/8" stereo patch cable for connecting model 1 Genesis audio.
Model 2 Sega Geneis's do not officaly work with an original top-loading SegaCD unit. They will, but you won't get Genesis generated sound. This is because the model 2 Genesis has audio-out on the expansion connector and no headphone connector, where-as the model 1 Genesis doesn't have expansion port audio-out, and does have a headphone connector.
The model 2 SegaCD was built to use either one (expansion audio-out, or patch cable from the headhpone jack), but the original model 1 SegaCD only supported the headphone patchcable.
But if you make your own cable, you can still use them together. If I remember, you just need to tap off the audio-out points of the model 2 Genesis, and route them to a 1/8" stereo plug to connect to the model 1 SegaCD, and you should be all set.
I also believe the metal RF shield/mounting plate of the model1 SegaCD will not mate up with a model 2 Genesis correctly, so you won't have to bother with attaching it. You may or may-not have RF issues. The SegaCD's & Genesis's were all pretty hit or miss about that. Some needed the plate, some didn't.
