This is a rare PAL version of the SEGA SC-3000H, with a black case and full white keyboard.

This machine was released in 1983 and features the same internals as the SG-1000 games console.

This is a full working bundle that's ready to go and includes:

* SEGA SC-3000H PAL version with real keyboard

* SEGA official UK power supply

* SC-3000 Survivors MegaCart with around 70 games, BASIC and more

The SC-3000 Survivors Multicart alone costs $95USD as each one is made individually to order by a lovely guy in New Zealand. I believe it contains every game for the SC-3000, but not sure. It's certainly a lot of games, along with BASIC Level 3, which is usually a separate cart.  The cartridge also has a menu system and a reset button on top, so loading games is very quick and easy.

Note that the SC-3000 contains no internal ROMs, so you need to have the cartridge inserted when turning it on. If you get a black screen, try cleaning the cartridge port and re-inserting the cartridge.

This is a complete, working bundle that can be plugged into any TV with a composite video input. 

Also note that the included power supply was originally from a MegaDrive, as the SC-3000 uses the same voltage and barrel jack. This is 9-10V centre negative, so if you're using a different power supply you must double check the polarity.  The PSU from a MegaDrive 2 was centre positive, so do not use one of those!
