Yeah, I know. I can't tell you, why they made the pads this way.

Hi ND40, Thanks for your interest. 1292-adapter cartridges, yes. Dragon Multicarts currently sold out, but new pcbs are already ordered. Will just take some time to assemble. I'll come back to you in a few weeks, right? Best regards, Roland

project update: I just got another batch of Odyssey2-extension-cartridges for using the Dragon-multicart on the Odyssey.

project update: I just got new Interton VC-4000 Extension pcbs today.

project update: Got new extension pcbs and eproms today.

I really don't know. You see that everywhere: calculator keyboards, remote controls ... Does anybody know? There could be a production problem with large copper areas, during the soldering process, maybe. Or plotter based layout tools, that could not do fillings, but only draw lines. But just guessing...

Repairing an Arcadia 2001 Controller I had problems with a fire button of the left Arcadia 2001 controller, not firing anymore. The Arcadia-controllers are very simple and were cheaply made. Even working, they are not great controllers. In the end nothing will help, but making complete new controllers of quality components, with real switches. I might do that sometime, if there should be some games I really like and want to play decently. Not sure yet. But for the beginning a repair should be enough. Simultaneously I'm using the opportunity to preserve that technology by uploading a few pictures. That's my left controller: Inside everything is glued together. By pulling carefully the parts can be separated. The mylar is quite corroded and a bit dirty: Showing the color scheme the plug: The wiring of the mylar itself, in case somebody wants to make a reproduction (or wonders, why pushing the "2"-key, also triggers the gun). Both red fire buttons are wired in parallel. They are just simple buttons, no rocker switches, no up and down. It is a 5x5 millimeters grid in the background. I cleaned the corrosion and without heavy rubbing, not only oxidation went off, but also the printed conducting traces. They really are not bound firmly with the plastic carrier. Look at the red circle. I cleaned away part of button and wire, by using alcohol, an ear pad and too much pressure and rubbing. Cleaning must be done extremely careful: For the first time I tried to repair with conducting silver, since soldering is impossible. I made a mask of transparent tape for painting the new trace. I learnt, painting one time is not enough: To lower electric resistance, the trace must be thicker. I painted three times. Narrow traces are bad, too. They have to be wide. Contact with the original traces must overlap as far as possible to make good contact. Left picture: painting a few times. Right picture: pulling off the tape. I also re-painted the conductive pad of the fire-button later on. I took no photo. Before reassembling I protected the new traces with transparent tape, since the silver color can't get inside the mylar's surface and gets scratched off quite easily. Reassembled the controller, checked it, working again! I can't predict, how long the new pad of the button will last, of course. Hopefully some time...

project update: Made a few Dragon Multi-carts (memory cartridges). Waiting for pcbs and eproms to be delivered ...

project update: Started delivering a few items and waiting for some components ... working ...

All right. Now I see your point. Only home-brew reproductions and copies, but not genuine Arcadia 2001 games. Thanks for clarifying. So, a Multi-cart even makes more sense, by enlarging the Arcadia's relatively small game library, if your focus is playing the games, not so much collecting original hardware.

Hm, thank you. In what respect, for example, is MPT-03 Circus different from Emerson Arcadia Circus? Or BlackJack and Poker? Or Nibbleman? Or Crazy Climber? Or Boxing? Or Auto Race? And so on ... There are pictures of the Arcadia 2001 boxes (with artwork) of those games in the web. Aren't those original releases for the Arcadia 2001? Are those only reproductions? I can't find a list of real original releases. They probably all got mixed up (?). Otherwise I still do not get, what makes them mpt-03 exclusive.

Oh, I see. I still have no real picture, which game is exclusive to which console of that group. All the MPT-03 games I saw on various webpages look very familiar. To me, they look exactly like corresponding Emerson Arcadia games. I'm probably Multi-cart-spoiled. Which are the MPT-03 only cartridge games? Can you name a few, please. Thank you!

Right, but the MPT-03 games all are available on the Emerson Arcadia, too. Just the same, only different cartridge hardware. You can use the Emerson Cartridges or a Multi-cartridge to play exactly those games.

I think, I do, in a certain way. As far as I understood the internet resources, MPT-03 consoles are compatible to the Emerson Arcadia 2001, except pin-out and format of the cartridge slot. The games are the same. They sold all the MPT-03 games also on Emerson-cartridges, maybe with slightly different names. Are there any exceptions? So, you can play all those games on the Arcadia, too. Or do you want original MPT-03-cartridge-hardware on Emerson consoles? What exactly are you looking for? Please explain.

project update: Made minor revisions of Odyssey Adapter and Interton Adapter. Ordered new pcbs for both extensions ... working ...

project update: Trying to make some progress. Only little spare time for retro. Burning eproms, building devices, testing, trying to process a few orders ... working ...

Basic soldering, as required for this little project, really is no rocket science. Just take a couple of wires, maybe some trashed pcbs and an electronics soldering iron and play around. Try to solder wires onto pads or connect wires. Desolder components. Solder again. With some practice, you will be able to do a job like this. I'm sure, there are tutorial videos on youtube or on www.weller-tools.com or the homepage of the other manufacturers. It is fun!

Oh, this old thread is coming up again?! Thanks, the selector box still is working. It's a really simple mechanical approach. Anybody can build this, with some basic soldering. I think I even have some hand wriiten documents. Some notes how I wired the thing.

Ohhh, , not a record? But you are right. I saw the counter jump to something like 270 views, as soon as I posted the 2nd entry. And was wondering why!

This really is funny, This post has been out for seven months and it collected 0 views and 0 responses! This simply must be a record ! ​It certainly is the most boring and irrelevant topic, that ever made it to the AtariAge-Forum! Yeah, I did it! Try to beat it, if you can... And nonetheless, I sold a couple of those adapters. Probably, many people simply do not know "AVPS" or "1292", but simply Radofin or Acetronic.

Hi Phil, I just switch to PM, since our ordering details and talking certainly are not of public interest. Just trying to keep the thread "clean". All right? -Rolo

I would like to add something to clarify things: The Dragon Multi-cart is the common memory device for all the systems (named after the computer, for which I started the project). There is one eprom included, which holds 64 games. You can swap eproms and burn your own eproms as you like. You can freely mix games for all consoles on one eprom. The "Extension Cartridges" are nothing but adapters for the different systems. I'm only making small numbers, since sales figures usually are quite low. This means, I'm running out of items quite easily. In most cases, I'm offering to register on waiting lists and I start to reproduce, when orders reach a certain threshold. This is not a commercial offer. There is no shop involved or something like that. It is just a private hobby project. For ordering just send me a PM and tell me what you want. I'll respond as soon as I can. Payment: Paypal or international money transfer directly to my bank account. I recommend to have an eprom burner and an UV-eraser (easy and cheap to acquire on ebay from China) to be able to change and burn your own eproms. Especially if you are planning to use the Multi-Cart for different systems. Please check out the feedback page: http://atariage.com/forums/topic/258478-rolo/

Hi Phil, Thank you for checking out my project. Maybe I have to add some information to my post. I'll do so. Yes, the Dragon Multi-cart is the common memory device for all the systems (named after the computer, for which I started the project). The extensions are nothing but adapters for the different systems. There is one eprom included, which can hold 64 games. You can swap eproms and burn your own eproms as you like. You can freely mix games for all consoles on one eprom. No problem. It is a very simple device, which is easy to understand and to operate. The Odyssey-Extension are currently sold out. I could put you on a waiting list for those, if you like. I have a final Interton Extension left. I should start to reproduce those, too. But after an initial rush, sales have been very, very, very weak ever since. And I'm running out of Dragon Multi-carts... Always the same, I do not want to have too much stock laying around, eating up money and space, but when people start ordering, I'm running out of stuff. I might not be the best salesman. Ordering is easy. Just send me a PM and I'll respond. Paying via Paypal or international money transfer, as you wish. Best regards, Rolo

Extension Cartridge for Emerson Arcadia 2001 family available Just a link, if you are looking for a multi-cartridge for Emerson Arcadia 2001: http://atariage.com/forums/topic/242786-multi-cartridge-for-dragoncoco-2-available/page-3?do=findComment&comment=4082727

Extension Cartridge for Emerson Arcadia 2001 family available I made a new extension cartridge connecting the Dragon Multi-Cart to an Emerson Arcadia 2001-console. Wikipedia shows a huge variety of clones: https://en.wikipedia.org/wiki/Arcadia_2001. I'm having a HANIMEX HMG-2650, which is identical to the Emerson Arcadia 2001. There are five software compatible sub-families, with unfortunately different cartridge slots. Please consider this. Currently I'm not having any plans to also build extension cartridges for the other sub-types. I loaded an eprom with 64 games for testing, all of them are running flawlessly, as far as I noticed. All cartridges available in limited numbers. Please allow some time to manufacture and ship the products. It's a strictly manual (hobby-) process. Price US$13.99 plus shipping! Please use PM. Rolo
