@stupus: That is so KEWL!!! Never seen in reality any Elf, VIP, Super Elf or Membership Card. Only pictures of them (and again!) Wish they could have been to PAX as it's a 6 hour drive from where i live (i live too far north... ;P ).

@stupus: That's a good question! Maybe... ?! Would need to dissasembled the Toshiba rom dump and also the Toshiba BIOS. And that isn't my cup of tea. Maybe Paul could ?!

While on the subject of RCA Studio II and family, Paul Robson has some extraordinary information regarding the RCA Arcade (or CoinOp) as he has documents about this mystical arcade! And not only that, he also made an emulator of the "FRED" computer with some games to play with...This guy totally ROCKS!!! Major Kudos for Paul!!! =) Check out his blog about the Cosmac CoinOp here: http://cosmaccoinop.blogspot.ca/

The thing about the Toshiba ROMs cartridge is that they are compatible with Eproms (27Cxx) and not like the CDP1831 roms. On an RCA Studio II or Victory-3 (European clones, aka Studio III), is if you use an EPROM, you need two TTL's to make it work BUT...on a Toshiba, those TTL's are already integrated in the system so you just need an EPROM connected directly into the cartridge port as the decoders (the TTL's) are in the system. I've made a schematic to how to connect a 2716 EPROM to the Toshiba cart slot: And here's a picture of the Toshiba PCB: And i have almost finished making a EPROM to cart adapter to try out on the Toshiba to prove it works (or not). But that adapter will have to wait for now. So the multicart that Flip is making can't work on a Toshiba BUT... could work if modified (or making a new one). =)

LOL!!!!! I'm laughing like a stupid hiena who's brain is about to explode, which i completely agree with ianoid...never make an hell of an offer to a seller (or a ridiculous one like $1) as he wrote this on the auction: "... has been referred to as the Holy Grail, an Urban Legend, a Myth and in fact has even been questioned as to its existence at all, some claiming, it was only a rumour that it existed." Well the cat is out of the bag so who's ready to send $3,500.00 on a game that was released in Europe, which if you look at one of the pictures, you see two drawn screenshots of the game and it looks so much like the European release. At least we have very good pictures of the complete game (well only missing one side of the manual) as i'll contemplate those pics. Hey it took 15 years to have those, so enjoy!

No need to imagine, just check this video on Youtube: https://www.youtube.com/watch?v=DtZEsXrE3Z4 But the game will be in black and white on a Studio II. We didn't get a release here in North America as RCA axed the Studio II only after 9 months (i'm maybe wrong on the time frame) and Bingo was intended to be release here but the programmer programmed the game with color for the Studio III, which you all know that the Studio III(3) are the European releases. Any Studio III(3) games can be played on the Studio II, only thing is that we don't have colors.

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 [email protected] -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 ---
