Hi There! I bought this one on a flea-market today. It came with 2 Controllers and NO powersupply. I have a real Mega Drive II (PAL), too. This Power Supply doesn´t fit - the plug doesn´t fit. So i also want to know, which powersupply i need. Thank you guys! Sorry, i can´t delete uploaded pic´s.....
Chips are marked wrong, not aware of any board revision with the Sega CD connector placed like that nor having a daughterboard at all. Probably a clone though that case is almost passable.
I would say it's a bootleg. The board and the cartridge slot doesn't look right. You can hope that the rating on the bottom is correct and you need a 10V @ 1A power supply, you'll need to measure the power connector to get the right spec for that.
Power Plug from Mega Drive II PAL is 10V 0.85A but plug doesn´t fit... OH MAN - how stupid??? When it´opened i can meassure which pin is + and which is -... DAMN.... so many trees around... Will a MEGA CD work?
O.K. i just tried to meassure - but can someone tell me where i can find GROUND on the board to meassure which pin from the plug is GROUND, too! THX I also bought a Mega Drive 1 today - but also without powersupply. And i already had a MegaDrive II (with red buttons). I own a cartdridge - yes, also one... - MEGA GAMES I (Super Hang on and World Cup Italia 90). This Cartridge fits into the MegaDrive and in this MegaDrive 2 "copy".
That heatsink should do the trick. Or look for ground planes. It seems the ones on your system are full of dots/holes, which is weird.
I don't recall Sega bothered having Mega Drive 2 block the shape of non Japan games. Their front doesn't mention a "cartridge lock" like Mega Drive 1 did.
Find a hole where a capacitor goes (there are lots of them not populated on your board). See the + symbol? use the other one.
I've seen those machines turn up often - MK-1631-07 or MK-1631-16, and serial number starting with AE0... . They look very odd, and I'm never sure if they are bootlegs, official hardware, or semi-official hardware. The one you posted is a Chinese aftermarket unit; it has third party chips but apparently it matches the original Megadrive hardware. That TV16B / TA-06S combination is used in a variety of Megadrive clones.
The big shiny metal block with dents is a heatsink. Also, as BadAd said, the (-) leg of most capacitors should be linked to the ground. Another good spot is the "shield" of the switch.
It's an asian... clone, of course. Original uses Sega-marked chips, 315-whatever. For this one, i don't like missing osc1, but if there's a smaller one somewhere then it will work. How good ? Depends on analog parts, PCB layout, soldering quality etc. I had 2 TA-xxx-based clones. One was utter trash, noisy audio and video, random crashes/reboots. Second one played all my 200 games just fine, with good picture and sound, Mega CD and 32x worked fine too. And the best part - composite video output was better than original MD1 one.
