Commando game repro for A7800

Hello to all.

Reading an article about the next generation Atari's console's after VCS2600 era, I meet for first time the Atari7800 game console. 

I was impressed with the so many similarities on hardware with other 8 bit computers of the same company. A big mystery for me   is why not use as standard a Pokey ic on board, something that would greatly improve the audio capabilities of the console! Remember that we talking for the flagship game console of the company for that era....

So many Games which are rewritten for this, could have much better sound from the "zip zip and zap"   of an ic constructed for a console of the year 1977.

Also with the simple addition of this ic new horizons will unfold, like SIO communication, external keyboard , paddles, light pens, touch tablets, and generally support for many joy ports simultaneously.

Ok I know cause many of the above exceeds the functions of a game console, and simply referred to as capability.

Anyway all that gone, and now if some game publisher wanted to do better sounds should have dissipate one Pokey ic on its cartridge!!!!!  Of course this also mean extra pcb and logic ic on cart, and finally a high price rate for the end customer.

 In my personal view, clear proof of the above is the existence of only two games who have a Pokey on its cartridge. Ballblazer and Commando.

 

 Now to the point.

 Before half month start looking for a schematic on the Commando game, and thanks to admirably website work of Mr. Dan Boris, I succeed design the pcb. For the external dimmensions I use as pattern the pcb of a Karateka cartridge. 

 - I decide to make a world wide edition which will may work on any PAL or NTSC A7800 console. This is possible with a very tiny pinhole on the side of the cartridge, who give access in an internal micro switch.

 - The entire surface of pcb is coated with ENIG (gold plated).

 - Pokey ic is in NOS condition never used before, purchased from B & C Computer Visions and placed on a 40 pin socket. You now cause these ic's will not exist for ever, and therefore deserve our respect.  

 - I have use plastic enclosures from original second hand Atari 7800 cartridges, without scratches etc.

-  Last the decall on front and up edge is new and printed on PET glossy paper. A big thanks on KevinMos3 for 

 the label arrangement.

 Kevin on my eyes you are professional!!

 

 Guys, if any of you would like to have a complete cartridge for your collection, as is in photos below, I can make one for you. Total cost including tracked shipping and Paypal fee will be 38 euro equal some to 50$. 

I will be happy if finally were able to sell the few cartridges here on AtariAge. As with all my build so far, so will be available only once.

 

Thank you  Panos.
