no edit summary
Over its lifetime, the Genesis came in three different models, each of which had several motherboard revisions. For more details, see [[Sega Genesis Hardware]].
===Sega Mega Drive/Genesis [Model model 1]===[[File:Genesis_system.jpg|thumb|200px|Model 1 Genesis]]
The model 1 Sega Genesis is the largest model and features a headphone jack with a volume slider. There are at least seven motherboard revisions of the model 1 that are known to exist, labeled VA1 - VA7. Early revisions, which bear the text "HIGH DEFINITION GRAPHICS" in white above the cartridge slot, are considered to have the best audio output of any version of the Genesis. The VA7 is the latest revision, and internally they are similar to the model 2 Genesis, and they do not have the "HIGH DEFINITION GRAPHICS" text on them.
*Model number: 1601-15 (revision without the EXT port)
*Not region locked.

===Sega Mega Drive/Genesis [Model model 2]===[[File:Genesis-model2.jpg|thumb|200px|Model 2 Genesis]]
The model 2 was smaller than the model 1 and lacked a headphone jack but was capable of outputting stereo audio through its rear A/V multi-out port.
Changing in the audio mixing circuts of the model 2 genesis gave it lesser sound quality than the early model 1 genesis.

===Sega Mega Drive/Genesis [Model model 3]===
[[File:Genesis-model3.jpg|thumb|200px|Model 3 Genesis]]
The sega genesis model 3 was released exclusively to North America in 1998 as a "budget system", and sold for $50. Many features were removed as cost cutting measures such as the expansion slot used by the sega cd, stereo sound, and a power LED.
The genesis 3 had compatability issues with virtua racing the sega 32x, and the power base converter and could not be used with the sega cd due to the lack of an expansion slot. The genesis 3 had compatibility issues with virtua racing.
A addressing bug was fixed with the genesis 3, which makes it incompatable with games that exploit this bug.
