Entex Space Invader with the TI chip has an SDIP TMS-1100 marked MP1211 MSL^8114 and it's a Rev B.

So it COULD be pre-rev E even in 82, depends I guess when the masks were made. Given the 6011? number on the chip matches the older game its possible this could be a fairly old 'alternate rules pinball mask' which was ramped up later.

Worth a try to dump it electrically, probably.

Here's the back of the board:

Kind of a quick-and-dirty iPhone pic... I can take a better one if something isn't easy to see... smile

Rik- that looks good. I'm pretty sure it's the same pinout. On the front, could you tell me the colors of the 2 resistors below the skill switch? Those and the one to the left (which I can see) are switched in based on the skill setting and change the oscillator speed. Also, can you read the value of the capacitor under the TMS1100? Not the cylindrical electrolytic, but the disc cap between it and the chip? It probably says 47 on it. It also determines the clock speed. Thanks.

I agree it's worth a try. Dumping would not damage the chip if it is an E or G revision anyway. If it's an E and there were just a few changes from RTD's code, I wonder if we could figure out the 8th bits.

The back of the RTD PCB says "ENTEX PONY PINBALL 6011". So I bet RTD is 6011 and BK is 6011A. It's interesting that both PCBs have 39 LEDs, but the RTD LEDs are numbered 1-43. Were 4 removed for cost reasons? Maybe they shrunk the playfield and those 4 no longer fit?

kevtris: If you do an update to svg's, could you do it on these instead of your own? due to them having grid/plates numbered.


Will do...

Someone wanted screen shots? smile Here's some, just as-is from MESS, left the Windows border there too (didn't feel like editing them... smile )

This game really needs the overlay to work as the ladders are printed on the game (not perfectly aligned here though...) :


Damn, I was totally going to spam the forum with a massive image post, but it limits you to 10 images it seems... smile More screenshots are here:

using the MESS naming...
(Or I can make another post like this if someone wants me to... smile )
It's been fun playing these at work (I can get away with that occasionally) and having people walk by and recognizing them!

It's actually easier to use the built-in MESS screenshot feature than the Windows Print-Screen feature. If memory serves it won't screenshot with artwork by default but there's some setting change or key modifier that will allow it. (AFK at the moment or I'd check.)

It was making weird, stretched images (forcing them 640x480 it looked like)... I wasn't sure if that was just a configuration problem or what, so I just used the print-screen option. I can do that pretty quick, although it does require an extra step or two... smile
