I used to think that I had seen the most of Sega throught the years...But obviously I was wrong...Different regions and zones, open the doors to other styles of gaming life and cultures out there....Recently, I have been able to obtain a Tec-toy Mega Drive III system...As many of you know, Tectoy was the offcial distributor of Sega products in Brazil and probably other parts of South America as well since the late 80's and early 90's....One of their products was the Mega drive III, which for some of us living in USA soil, could equal to be a Sega Genesis model 2, or so I thought (Explanation below)..
It seems that there were several revisions made to the Mega Drive III....I have seen models with and without built-in games. there are models that have as many as 30 memory built-in games and still have a full cartridge connector port...
My particular official Sega Tectoy Mega Drive III model came with 10 memory built-in games: Super Hang-On, Golden Axe, Columns, Sonic the Hedgehog, Streets Of Rage, The Revenge Of Shinobi, California Games, Sega Soccer, Super Monaco GP and Flicky..
The Design of the Mega Drive III shell is basically the same as the Sega Genesis 2/MegaDrive 2 System...But the weight and plastic quality of the tectoy Mega Drive III is different ...
The plastic quality of the case is a bit hard to explain, is definitely cheaper than a Sega Genesis model 2 system, but much,much better than any other now a days Sega clone system, including the GEN-X, GN-TWIN and others.

The system itself has a built-in power cord, but other revisions have a power port for a power supply just like the Sega Genesis model 2 or Mega Drive 2 do...This Mega Drive III is 110V/220V 50/60Hz Automatic switch compatible and has Type C prongs (European 2 round pin power plug connector)...

The bottom side has the system specs as well as the "Produced by and under License of Sega Enterprises Ltd Japan"label
Microprocessor: MC (68000) 16 bits
Ram: 576K Bits
Video Ram: 512K Bits
Colors: 512
Resolution: 256X224
Audio: 9 Channels
But as soon as the top cover comes off, you can see what the internal system is really made of

For once, it lacks the Sega CD system compatibility (no connector) even though it has the expansion door,most likely for previous revisions and for my amazement the system has the 315-6123 ASIC found in the last revision of the American Majesco Mini Sega Genesis 3 System....Now I truly know who to blame for this, TECTOY!!!!!!!!!....There is no Virtua Racing compatibility and just as a Sega Genesis 3, no 32X system compatibility either....But funny enough, the B19 cartridge pin is connected, so there is Game Genie compatibility at least, something the the Genesis 3 doesn't natively have ....This is probably the why they decided to called it Mega Drive III perhaps....MD 3= Genesis 3......

On this pic, you can see the outputs of the system: the built-in RF output connector, the RF output channel switch (3-4), the 9 mini pin din connector with full RGB connections.....Closer to the actual cartridge connector you can see the ROM with the built-in games (the one with the serial label) and just a little bit above there is the sound circuit as well as the CXA1645 video encoder, which by the way, this Megadrive III was totally set to PAL-M format.....I did a little bit of modding to make it full NTSC compatible...

This pic shows the 315-6123 ASIC, and the master clock oscillator....I had to replace that one to..
And finally, the board where the power current comes in and were the power switching takes place....This board has the "On/Off button", the controller port connectors and the "Reset"button as well ...

I got a Tectoy Sega Master System III too, another Brazilian Marvel, and so different to any other Sega Master System II that I have seen so far, technically speaking, but that's another story......
http://usera.imagecave.com/capcom2000/hpim8444.jpg
....If anyone one else out there happens to have a different revision of the Brazilian TECTOY Mega Drive III, would be really nice to see it, and what better place to show it than here at sega-16.com.....
Until next time!
