Prosystemsearch Posted June 17, 2014 Share Posted June 17, 2014 (edited) Has anybody as of yet found and located the surviving batches of GUMBY chips?? I would be overjoyed if someone did. That would be very good news for Homebrew developer, as there would be a new chip for sound for them to use!! :D :) Edited June 17, 2014 by Prosystemsearch Quote Link to comment Share on other sites More sharing options...

Greg2600 Posted June 17, 2014 Share Posted June 17, 2014 (edited) Doesn't matter if they are, because the schematics were obtained by the community years ago. Wouldn't make much sense either these days, as more robust solutions have been developed (CPU WIZ). Moreover, it's far easier/cheaper for homebrewers to just take Pokey chips off old carts.

AtariNerd Posted June 17, 2014 Share Posted June 17, 2014 Just a sec, after I've located the EntWives... (Sorry, not very helpful. I'll get my hat.) *whoosh* Quote Link to comment Share on other sites More sharing options...
Prosystemsearch Posted June 17, 2014 Author Share Posted June 17, 2014 GUMBY chips are out there. It would be nice to hear what a game with the GUMBY chip would sound like. Would it be like the POKEY chip?? Or would it be like the SID chip for the c64 and commodore 128?? Quote Link to comment Share on other sites More sharing options...

The schematics? What are the GUMBY's specs? Quote Link to comment Share on other sites More sharing options...
Greg2600 Posted June 17, 2014 Share Posted June 17, 2014 Oops, I confused it with the SuperCart. 7800_1mbit_DEV.PNG There was a discussion here about Gumby "what-if" specs. http://atariage.com/forums/topic/196351-quick-question-about-7800-sound-chip/?do=findComment&comment=2879552 As I said though, pulling POKEY's or moving on to a super-cart like CPUWIZ's is fine these days.

Prosystemsearch Posted June 17, 2014 Author Share Posted June 17, 2014 BUMP It wouldn't hurt to use the schematics for the GUMBY to go and reconstruct some chips. Quote Link to comment Share on other sites More sharing options...

That's not definitive. Plus, if the Gumby was equal to 2 POKEYs, Atari could've simply made more DUAL POKEY, DUAL PORKEYs [stereo POKEY in a single chip], or QUAD POKEYs. All three of those were used by Atari Coin/Games. Quote Link to comment Share on other sites More sharing options...

Rybags Posted June 18, 2014 Share Posted June 18, 2014 Do schematics or specs even exist of the GCC Gumby? Even if they do, it'd be a case of AMY all over again. Little point recreating it because there's practically no software or use of the chip ever and there can be much better alternatives.

Little point recreating it because there's practically no software or use of the chip ever and there can be much better alternatives. Well, I understand the point of the question. If some can be found, then they can be reproduced. That would be better than schematics because it would be proof-of-concept. Go to Kickstarter thereafter and raise money for a production run. The same goes for AMY. Or, falling short of that, FPGAs could be done to emulate them. Sure, there are modern chips that are obviously better but they wouldn't be authentic nor would they show us what we could've had had the cards been dealt differently back in 1984+. I'd love to see the AMY completed. It would make news amongst retro chip tunes enthusiasts plus the home brew community here would probably try to add it to so many different Atari products - because Atari Inc/Corp would've done that - A8 computers, the XEGS, 7800 cartridges, and the ST. Hell, after the release of the Commodore 64, Atari Inc. should've pumped out Quad POKEYs and added them to the XL computer line… 4 Quote Link to comment Share on other sites More sharing options...
DracIsBack Posted June 18, 2014 Share Posted June 18, 2014 Not sure they were ever finished design. The folks at GCC would know. 2 Quote Link to comment Share on other sites More sharing options...
Rybags Posted June 18, 2014 Share Posted June 18, 2014 Schematics is a pretty broad description. I've seen plenty of Atari schematics before that in reality are little more than block diagrams and provide nowhere near the needed info for reverse-engineering. Really, a better alternative would probably be to develop some sort of cheap synth that resides on a PIC or AVR and can fit inside a cart. 1 Quote Link to comment Share on other sites More sharing options...

Trebor Posted June 18, 2014 Share Posted June 18, 2014 Forget GUMBY (or POKEY) - HOKEY will hopefully become the solution with a little more patience and time. 1 Quote Link to comment Share on other sites More sharing options...
Lynxpro Posted June 18, 2014 Share Posted June 18, 2014 He he. Was that sarcasm? I thought they had to turn those back over to NAMCO? From what I was informed of from an ex-Namco employee - who is also a member of this site - this weekend, GCC owns the intellectual property to anything that was introduced in the Ms Pac-Man game such as the bouncing fruit mechanics. So if that's used in any Pac-Man game or Ms Pac-Man is included in a compilation, GCC gets paid. They certainly aren't keeping their lights on from their laser printer business or their website that hasn't been updated since 2004. Maybe their business model consists of maintaining a website almost as bad as Best Electronics! Quote Link to comment Share on other sites More sharing options...
Bakasama Posted June 18, 2014 Share Posted June 18, 2014 So would that explain why a some of ideas in Ms. Pac-Man don't get used in other, later Pac-Man games. 1 Quote Link to comment Share on other sites More sharing options...
Lynxpro Posted June 19, 2014 Share Posted June 19, 2014 So would that explain why a some of ideas in Ms. Pac-Man don't get used in other, later Pac-Man games. Precisely! They should just buy out GCC. Quote Link to comment Share on other sites More sharing options...
Jaynz Posted June 20, 2014 Share Posted June 20, 2014 Well, from Japan's point of view, the only other 'classic' style PacMan games after Ms Pacman were Super PacMan, Pac and Pal, and Pacmania... so not a lot to go from. The US got Baby PacMan and Jr PacMan - the latter DID use the bouncing fruit... but neither of those games are recognized by Namco. Quote Link to comment Share on other sites More sharing options...

I remember a pirated version in the arcade called "Pop-Man" which was a crude Popeye as Pac-Man. Quote Link to comment Share on other sites More sharing options...
PacManPlus Posted June 21, 2014 Share Posted June 21, 2014 Yep... The version I saw was actually Hangly-Man, with the Popeye head. Quote Link to comment Share on other sites More sharing options...
