No problem at all, glad to read that tsunoni has offered you to mod your Pong console. =) --- Sly DC ---

Hi swlovinist, I would be glad to mod one for you at no charge but the problem is that i live in Canada and shipping a console is now at least $25 and another $25 to ship it back so this is not recommended. Which Telstar model you have ? Or if you want to mod another Pong console, which is it ? I have modded a couple of Pong consoles, dedicated consoles and game systems like Atari 2600, Colecovision, RCA Studio II, etc. Most of the videos on my Youtube channel comes from game consoles/systems i've modded myself. It would be my pleasure if i can help out in any way. =) --- Sly DC ---

Hi decle, I used MAME 0.167 for Windows (32-bit) to try out your lilBro.rom and didn't heard any sounds. Quote: "I think you can play all the games on MAME / MESS right now if you want, using the unichamp driver and optionally the -cart flag to specify one of the pacs." Exactly, you need to specify which cartridge with the "-cart" flag like this: MAME unichamp -window -video ddraw -cart pac-02 But if you want a crisp resolution instead of a smeared one, than type this: MAME unichamp -window -resolution 696x448@60 -video ddraw (and add "-cart xxxxx if you want to play with a specific cartridge without the extension).

Hi folks! Just tested out the lilBro.rom and i must congratulate decle of doing a heck of a good job! Seems there's no sounds but that's OK, it's not if any Champion 2711 are games of the year...lol! I would like to help out but when it comes to programming...well, let's just say that's a skill that i suck real hard. Just know BASIC (yes...i'm almost prehistoric...LOL!!), HTML and LUA. And i must also thank intvnut as he given me a few years back documents about the Gimini Challenger 8950 Programmable Game System aka the Champion 2711. I just uploaded all the docs from his web site regarding the Challenger 8950 on archive.org: https://archive.org/download/unichamp/gimicro.zip And if anyone wants to read the FAQ (last version is UC-03), just go here: http://www.ccjvq.com/slydc/index/faq/2711/index.htm Can't wait to see the other four PACs converted to the Intellivision! =) --- Sly DC ---

Hi tsunoni! Sorry for the long delay to getting back at you. I'm seeing and reading that you finally finished your A/V modding of your Coleco Telstar, that's great! Even if you had problems, you didn't gave up and that is a great quality. =) Batteries are not really recommended as when they are beginning to be drained, the voltage is too low and gives problems like distorted or snowy picture, etc. Always better with AC adaptors, in your case you need a 9 Volts/200 to 500milliAmps with positive tip. So i'm tipping my hat to your effort and your perseverance! =) -- Sly "forgot your name" DC --- (lol!)

@tsunoni: Sorry for the delay, OK now back to business: You used "un-isolated" copper wires ? YIKES! Don't use that! Use isolated wires like in this picture: I use simple A/V cable like those ones: With an isolated wire, there is two wires inside: one that is isolated (like the colored ones) and the other that is not isolated (the copper one). The copper one needs to be grounded and the other cables (the yellow one) needs to be soldered with the composite video output (the 5 pins together) and the white or red (or both) needs to be soldered to the pin #3 (sound output) and the copper again soldered to the ground. and the isolated cables needs to be stripped like that: When using copper wires like you did, this makes a LOT of trouble as any not-isolated cable can touch any solder point and make a connection causing a problem or another and also radio frequencies can do statics. Try this and let me know the result. Until next step! @PhileasJWhoopie: The Coleco Telstar Maksman uses a AY-3-8512-1 (16-pins chip) and i haven't tried to A/V mod one yet. As for your APF TV Fun, i would need the model to tell which chip is inside it and for the Unisonic Tournament 2000, that one uses a AY-3-8500-1 and is VERY EASY to A/V mod it. If i remember correctly, it has 4 in/out pins which are: +5 volts, ground, video and audio on a side of the RF modulator. I would need a picture of the RF modulator to tell you which pins is what as it was my very first A/V mod i did about ten years ago. --- Sly DC ---

If there is a schematic, only Curt would have it and as Clint Thomson wrote: "...Curt gets a stampede of requests...", so you still can ask him but it may takes quite a time before getting a replay (or until Curt read these posts). But there a few documentation you can read until then, check US Patent #4,421,317: http://www.google.com/patents/US4421317 And also this patent #D,269,087 (cartridge design): http://www.google.com/patents/USD269087 As for the CPU, it uses a COPS411 (same as Entex Adventurevision) in case you were wondering and all 8 games are already programmed in the CPU, which are: * Asteroids * Basketball * Destroyer (aka Sea Battle) * Football * Outlaw * Road Runner * Space Invaders * Superman *** Dodge 'Em - Never programmed/produced *** --- Sly DC ---

Hi again tsunoni, You could remove the chip and bend the pins but if you apply to much force, you'll break the chip. But if pins #6-9-10-24 + #16 are soldered on the back of the board then you can solder a wire on each solder point and then tie (or solder) them together. For the CD4072, generally all four video outputs are connected to this TTL but solder those four together will do the same job. The CD4011 is for the 2MHz clock. Here's a quick drawing (done in 2 minutes) to show how to connect the pins and how they are numbered: The pink arrow shows how to find pin #1. On any chip, there is always a small dented circle so this indicated pin #1. Pin #2 is the ground but you can find other ground solder links on the back of the board. Pin #3 is the sound output and pin #6+9+10+24 are the video output and pin #16 is the sync, so add all five together to get a composite video. There is also a schematic which should be quite close of the Coleco Telstar 6040: If you had a Coleco Telstar Alpha (model 6030), all four video outputs are soldered together, so i just soldered a wire from pin #16 to the four and output it with an A/V cable, like in this picture: (Look Ma! No electronic components for doing a A/V output! LOL!!!) The result of this mod (gameplays) can be seen here on Youtube: So keep me informed of the progress, until next time! --- Sly DC ---

Ok, you have a model 6040. It's hard to read which type of TTLs you have but i'm guessing that they are CD4072 as many manufacturer used this TTL as a video summer. Anyhow, just take the following pins from the AY-3-8500-1: #6 (ball output) + #9 (right player output) + #10 (left player output) + #24 (score & field output) and #16 (sync output) and tie them all together and this makes your composite video output. As for the sound, solder a wire to #3 (sound output) and this will be your Sound output. DO NOT solder a wire to one of the terminal of the speaker or at the emitter of the transistor as this gives a amplified sound (either the sound will be too loud or it will be too low). Try this and you should be able to play on any monitor/tv with a A/V input as a GI AY-3-8500-1 (or the PAL version: AY-3-8500 and even the Texas Instruments clones: TMS1955NL and TMS1965NL) doesn't need any op-amp circuit to amplify the signal "IF" the signal are taken directly from the selected pins mentioned above. Give me news on this when you can and have fun modding! =) --- Sly DC ---

Hi swlovinist, Yes, you can use the AC adapter from the Odyssey 4000 on the original Odyssey. Just be sure that the plug is the same size. And "IF" you have snow or distorted picture, use a higher milliamp like 250-300mA, can go up to 500mA and it won't be a problem as i'm using an old Atari 2600 AC adaptor for one of my Magnavox Odyssey (just changed the plug) and it works like a charm. --- Sly DC ---

Hi tsunoni, First, what is your Coleco Telstar model ? I have A/V modded some few Dedicated Pong consoles as well as other Dedicated consoles. The last one i've A/V modded was yesterday a Philips Las Vegas ES 2208. You can see a few of them on my Youtube channel but i'm not showing how to mod them, just posted videos to hear and see what they really look like. Anyhow, about half of the Telstar has a AY-3-8500-1 and it is very easy to mod for A/V (Audio/Video) output and the best is that you won't need any electronic components (like resistors, transistors, etc...), just a few wires (and a iron solder). And if you can, open up your Telstar and take a picture of the rear of the board (where all the solders are) so i can assist you step by step. Until next time! =) --- Sly DC ---

How about this ?

Thank you so much James! I greatly appreciate this as i didn't get the manual with my Toshiba Visicom (and the flyer too!) =) Now before i'm going to bed as i'm almost taking the keyboard for my pillow...has anyone ever wanted to have their Studio II A/V modded ? If so than take a peek here: http://rcastudio2.blogspot.ca/ Now i need to catch up my snooze! ;P

Hi toymailman, Could you scan the flyer and also the installation manual for archival purpose ? This would be a great add-on for the RCA Studio II archive. =)

Hi Fabrizio_s, Thanks for posting the pictures, especially it was an unknown RCA Studio II clone until you shown us. =) If you wanna laugh a little, the Trevi company in Quebec, Canada does sells pools and accessories, check here: http://www.trevi.com/ If you don't get any offer, than i suggest to sell it on Ebay.it and ships worldwide. --- Sly DC ---

@carlsson: You're right! I've inverted the image and it reads: BIOR.... (space) ?AM??, which if you deduce that all the TREVI has labels with M1200-xx as M1200 game systems so on the list of Conic/Sheen M1200 that game would be: M1200-02 // Biorhythm Games. Also, TREVI released a Pong console called the: Trevi Color TV Sport 406-6 which is a clone of the Conic TV Sports 406-6 (just for fact).

Ooohh....a new Rca Studio II clone that nobody knew, this is cool! =) Could you tell which game is the first one on the left ? Because of the flash glare, it is very hard to read the name of the game. And great find! You should take pictures of each game cartridges for archival purpose. Usually Conic or Sheen M-1200 game system are not much rare but this is the first time i'm seeing one with the "Trevi" brand name. You should easely get 150-200 euros for the whole lot (game system and games) and just the Pinball game is at least worth 50 euros minimum.

Hi! Sorry to dissapoint you but the Atari Video Pinball C-380 isn't emulated or simulated yet. Olivier of Old-computer made a rendered screenshot so it's not from any emulator or simulator. But it will be simulated one day because it can't be emulated, there is NO coding. It is just discrete component circuits reduced and compacted into one chip, same as the General Instrument AY-3-8500-1 as too many other pong consoles and dedicated game consoles. But i know there is a simulator of the Nintendo Block Kuzushi made for Windows and Xbox360. I did try out the Windows version and the coder made a hell of a fantastic job! He coded all 6 games PLUS 44 extra levels!! --- Sly DC ---

Hi folks, Been quite a time that i have made a post here, well to simply put, it took me almost three years to get my health back after an incedent and now, i'm almost 100% healthy but i do feel great (and it's great to be back on my two feets sort to speak). Enough of my health...i'm writing this post to announce that i will be releasing a simulator (NOT an emulator) of the Magnavox Odyssey in a very near future. I began coding it three years ago but after the incedent, it went like the good old TV show: "Lost in Space", but now i restarted to code it a few days ago and at the rate i'm going, it will be released very soon but just in case, i put myself a deadline before the end of this year. So check out the blog i have started about the OdySim here: http://odysim.blogspot.com and how it's progressing. If you have any idea(s) or even nitpicks, don't be shy to share them, thanks! =) --- Sly DC ---

Ok, now for how to mod a Toshiba Visicom COM-100: It is really simple actually, you will only need to solder (or tie together...not the best thing but only do this if you don't have a solder iron) 3 wires! One for the video, one for the audio and one for the ground. At first when i've opened the console, i was hesitant since everything written is in Japanese but once i saw only seven wires connected to the RF modulator, it was much easier than to translate...lol! There is three yellow wires which are connected to a switch, these three you can cut since it's only for channel 1 & 2 and you can also cut the wire next to the yellow indicated by a weird "N" symbol (that one is the +5V). Now that four wires are cut, there is only three left (those that we need). Now cut those three and solder/wire them to the appropriate output (video = yellow, audio = red and ground ....is ground! lol!). Voila! Told you guys that it was simple! Here's the picture how to do it: Now the next mod i'm going to do for the Toshiba Visicom is a cartridge adaptor to see how Studio II/MPT-02 cartridges look like. Will the Toshiba displays the same colors or only 2 or more colors ? We'll only know when the cart adaptor will be done since the Visicom cart pinouts doesn't match the Studio II/MPT-02. I think Charles McDonald posted the pinout of the Visicom cartridge, but i'll use my multimeter to check where each pins goes where in the Visicom. It won't take too long since there is only 22-pins. Next A/V mod, either the RCA Studio II or the Conic M-1200 coming soon. =) --- Sly DC ---

@carlsson: Completely agree with you that European clones have a better "color palette" than the Toshiba Visicom. But if you check the guts of a Conic M-1200 and the Toshiba Visicom, you'll notice that the two doesn't use the same color encoding circuits, The Conic uses two TTL's (CD4001 & CD4069) with a PAL Color encoder circuit and the Toshiba uses a lot of transistors. Even an MTP-02 (say...Hanimex) uses a PAL color encoding circuit with five TTL's. Would love to have HD pics of an MPT-02 (Hanimex or Soundic) board (both sides) to see how the color encoder circuit is interconnected. @Blazing Lazers: Thanks. I'm looking forward to read what you'll find at the RCA archives. I'll post later today how i mod the Toshiba Visicom and also the Conic M-1200 but as for the RCA Studio II how to mod it, i did it some time ago but never finished the mod itself (boost the video signal). Check here: http://atariage.com/forums/topic/209519-rca-studio-ii-gold-mine-an-interview-with-the-studio-2-production-manager/page-12?do=findComment&comment=2735241 After i've finished modding the Conic M-1200 with A/V output (just made a test if it worked or not), i'll do the Studio II. I'm pretty sure that i'll only need 3 components (x1 transistor and x2 resistors) to make the video mod. And maybe i'll also try the pause button mod, a reverse-video mod and...err...i'll stop right there. =p --- Sly DC ---

Hi folks, been quite a while i've posted here. Well, i've received 2 days ago something pretty rare and since the person who sold me this game system said that it was broken, i simply tried to see if it works or not. Just to say, i've modded it with A/V output (which is sssooo damn easy to do BTW) and recorded this: https://www.youtube.com/watch?v=BKsR-LYN2vs Already 4 views in less than 12 hours before i've posted here.....KEWL! --- Sly DC ---

Sorry about this, my web site was infected by a $%?$%?$ virus and Google virus alert was intefering with my web site. Now my web site has come back from the "dead" status and virus free. If there is anything on my web site that's not properly working, please let me know. Thanks very much! --- Sly DC ---

Hi rsb0204, Nope, an European game console/system will NOT work on an NTSC television, the vertical sync will roll and also you will lose color. Either on a old TV (you may adjust the vertical knob) but still you won't have color. What i did to be able to play with a Conic M1200 was by converting it to Audio/Video (A/V) and plug it on an small NTSC/PAL TFT monitor (can ind these for around $30 on YouPay). Now i can play RCA Studio II/clones games in color! =) --- Sly DC ---

It's been 3-4 days now i'm trying to "clean-up" my database of Studio II stuffs and clones. As i was writing down notes on paper (just in case my HD brakes down...) about the Hanimex MPT-02, i just discovered that this game system (and maybe also the Soundic Victory MPT-02) doesn't have any built-in games! Upon checking a picture of the unit board: You can see that U13 and U14 are missing and these IC's are the ones that have the built-in games. So now i understand why the hell there is the "Grand Pack" cartridge since all other clones (surely accept the Soundic) doesn't have this cartridge listed or available. For those who doesn't know, the "Grand Pack" cartridge contains the same five games found in all other European clones: Doodle, Patterns, Bowling, Blackjack 1 player and Blackjack 2 players. So if anyone has a Soundic Victory MPT-02, could you open it up and tell us if this one also doesn't have any U13 & U14 chips ? Also, a high resolution of the Soundic board would be greatly appreciated since i wanna know why the MPT-02 has a bright magenta for background instead of the blue backgound found in M-1200 series (Conic/Sheen M-1200 and Mustang 9016). Still leaving the Academy Apollo 80 wondering which color background it has. And for last, there is 3 other Studio II homebrew games made by Lee Romanow: Outbreak, Climber and TV Arcade 2012.. These roms are available on Yahoo rcacosmac group ( http://dir.groups.yahoo.com/group/rcacosmac/ ) in the files section under the "Studio II and clones" folder. Also, the TV Arcade 2012 rom, it's a 5-in-1 multi-games which contains these games: Craps / Moon Lander / Repeat After Me / Space Rescue / Nim. --- Sly DC --- (has left the studio... - instead of "left the building"...LOL!!!)
