SIO2

As Wickeycolumbus said, I did not receive the poster with the rest of the game/box/manual/stuff. I just wondered if the poster is on its way here because, I will probably be ready to move this along early next week. I still need to get some photos and will spend some more time playing the game this weekend but, I think I know what I need to for my review.

The save key on the left in the photo is traveling with Boulder Dash. I just wanted to make a save key for myself in case I write a game where I want to save a score. I also have Atarivox but I have several systems that I play and I just leave Atarivox connected to the one console. The save key size makes it pretty convenient to move between consoles. Better get in line for Boulder Dash Jinks. It is coming to Canada next if King_Salamon's location is correct.

Please disregard previous post. I figured it out. I also tied all floating pins to ground (not shown in diagram).

Are there plans available for the save key? I think I would like to build one for myself while I have Boulder Dash here to test it with. I think I have the components on hand. I have the db9 and the 24LC256 and some perf board. What else is there? I can not tell because of the glue.

Just seeing how it looks in my cabinet. Good right?

Got it today. Look forward to playing it soon.

I really like that. I am going to have to try it. Is there any special purpose to the half circle cuts in the board?

I like the graphic for the flies in the 2600 version better. Otherwise, the 7800 version kicks butt.

So, offer $20 or build your own.

Just curious but I notice that the serial number stickers on those Best machines have square corners. Seems like all the units I have seen have rounded corners. Maybe Best creates their own label as part of the restore.

Nice 64c.

If it were mine, I probably would attach wires at the pads where the pokey pins come through the board and shrink tube the wires to the cap leads (observe the polarity for the cap). Or at least shrink tube the cap leads if they will span the gap between the pins. I think you have the correct pins identified.

Congratulations toiletunes! Awesome job!

Sure, I will give it a try when my turn comes up.

Just embrace it. I am old. What the hey. I have played my share of Zelda and Mario games too. These days though I would rather play Pac-man for the 9 millionth time than switch on my PS4. And I love the PS4 aside from all that online crap where you have to download an update for a brand new game. Excuse me now, I have to go play Pac-man again. Looking at you tep392.

Made the mistake of playing this with a Proline. Ouch!

Good to hear from you batari. Glad you are feeling better.

Alternate music version with auto fire on. Enjoying this very much.

Not sure what happened. I put the Ultimate SD cart in my 5200 but every time I tried to start this game, some Sega Genesis game kept coming up on screen. Just kidding. This game is amazing! Thank you. 40,290 my high score so far.

That is no disaster area. It looks like a cover photo for some electronics magazine. Nice.
