Not necessarily. Some Heavy Sixers were made in Taiwan. Atari is hard to keep up with they did so many strange things.

If its made in Taiwan then its a light sixer.

Two deluxe on the way. Cant wait.

Maybe one of the traces or a soldering point went bad, have you tried opening the cart? Marty Yes everything looks good inside

Probably new parts are out of the question. I'll try the oil thing. I do have the first style to get me by. I worry that if I use it to much it will wear out a part I can't get or lack the knowledge to figure out. I'm learning new things every day about electronics and gaming systems. Maybe some day I will be able to fix most things that come my way. I can usually fix cart based systems when broken but cd stuff is kind of a new thing for me. Thanks for all the help everyone.

It's not a ROM chip inside, they are self contained dedicated games. Similar to what Atari was going to do with it's Game Brain, the console itself is just used for power, display, and game controls - basically an empty shell. Each of the Telstar Arcade carts have all the actual game circuitry on the cart in the form of single a chip micro-controller/rom combo, the MOS tech MPS-7600. Thank you for the info. This helps me better understand the system. That must be why there is no black screen when the broken game is inserted.

Thanks I'm in no rush. I still have a bit of research to do and information on these systems seems scarce. At least now I know it's possible to get rom and possibly fix it. I've been looking for cart #4 as it is the only one I don't have. My friend said I could borrow his cart#1 to dump the rom but I never messed with these. If it were an atari 2600 or 7800 it wouldn't be a problem as I recently modded my 7800 into a cart dumper with some help from some great people here. I have 3 of these systems now. Can one be modded to dump carts or is there another way? I hate to mod one as rare as they are. I'm hoping to keep a spare and possibly sell one. Again thank you.

I have cart #1 that doesn't work. When I turn on the system I hear a noise then nothing. I cleaned the system and the cart and it didn't help. My other carts work great. I believe the rom chip must have died some how. Is there a way to get a copy of the rom? can i fix it with an eprom? Where can I find info on this system? Any help would be greatly appreciated.

I like the joke. lol

Does it feel like the bearings are dry? If it's just turning rough, a little lightweight oil will help until you can replace the motor. The only bad thing is that if there's a little grease left in there from the factory, oil will wash it out. If you can see the bearings and get some silicone grease into them, that might solve the problem for quite a while. No it only turns hard when power is going to it

looks like my drive motor isn't working. Seems to turn dry. Is there a place to get these?

My connection is ok on the console and my console works with my friends cd unit. I'll check the things you mentioned. thanks

It sounds like its spinning the disk

mine just reads no disk and the power light flashes. My friends system has a steady on power light

I just got a Sega cd the second model. When I turn it on with a cd in the unit the power light flashes but the cd system powers up and says reading cd then asks you to press start. When I press start It says there's no cd. I know its a problem with the cd unit itself as I tried all the hookups on a friends along with the cd and his worked. I cleaned the eye and it didn't help. Any ideas would be great. Thanks

I just want this stuff gone. I have other parts for the KTM 125 and Suzuki lt125's and will be parting out an 73 atc 70. http://my.ebay.com/ws/eBayISAPI.dll?MyEbayBeta&CurrentPage=MyeBayNextSelling&ssPageName=STRK:ME:LNLK:MESEX

Yes you can use those boards but 2764 is only 8K you will need 27256 eproms for 32k games. You will also need to add in inverter (74ls04 or similar) to the output enable line to go from the eprom to the pcb. To make things a little easier for you untill you know more about how eproms work the OE is pin 22 on your eprom or just count 7 legs from the bottom right of the eprom with the groove on the eprom also facing right. You will need to bend the leg up to attach it to your inverter chip. When you hook up the inverter (say it's a 74ls04) you will need pins 1,2,7,14. 1 is input, 2 is output, 7 is gound, 14 is 5V. They will all need to be attached. The input and output lines on the inverter go to pin 22 of the eprom and the hole on the pcb under it. 5V (pin 14) goes to pin 28 of the pcb, GND (pin 7) goes to pin 14 of the pcb. Will it matter if I use a 27c256 instead of a 27256 eprom? The price I found on 27c256 is far cheaper than the other Yes, you can use a 27c256. Thank you

My Frogger 2 works fine to but I do have 7800 games that won't fit the cart slot like Missing in action but it fits my other 7800. Has anyone had this issue? I had the system apart for a dev mod and never checked for a fit before the mod. Wonder if maybe my mother board is positioned right though this seems to be the only game I have an issue with. Oh both of my 7800's have the expansion port.

eBay does this almost automatically with certain auction categories; basically, they assume you might have unlisted multiples that you would sell and want to give you the option to do so immediately (so they can get their cut quicker). You should just ignore it unless you want to sell unlisted multiples to your auction's bidders. This is good to know. Thank you

Thanks for the info. This will help a lot.

Thanks for the help. I bet its that I had 2 RM250 cdi boxes for different years ending at the same time. I sent an invoice and will wait and see.

There was no reserve so should I contact the buyer of assume he backed out? I am new to this. thank you

I sold an item on ebay but as soon as the auction ended it said it was eligible for a second chance offer. What does that mean? What do I need to do?

I have a bunch of CA024927 rev A pcb's and I'm wondering If I can use these with 28 pin 2764 eproms to make 32k home brew carts for my 7800? Where do I find info on this?
