The chip was shifted over to the right as it is now.

The board has provisions for the larger socket. Nothing was trimmed to make to make it work.

So i cleaned the board with alcohol and I ran it through my ultrasonic. I also touched up any questionable solder joints and there was no change. The pink screen persists with or without a cart.

It was an early learning experience for me definitely...Inam older and wiser now lol

Here are photos. I haven't cleaned the bottom of the board yet.

I replaced the CPU and the ANTIC with no change. With the adjustment dead center, it's a pink screen. I was planning a ram upgrade, maybe I should proceed and see if it comes back to life?

I have a 600XL that I just recapped and added the monitor port to. It was working and younger, inexperienced me decided it would be a good idea to replace the sockets on all the ICs. After that, it died. I just recently decided to get it going again so I carefully removed all the new sockets and checked for any bad traces. I only found one and repaired it. The machine still doesn't boot. It will only show a pinkish/red screen. I checked volage and all chips are getting around 4.8-4.9 volts. The CPU and ANTIC are the only ones getting hot. Where should I start?

That was the point of removing an unused serial or parallel connector so I won't have to modify the case and it would be reversible later if I wanted.

I have acquired a 520st recently and I am wondering if an internal gotek would be possible? I was thinking about adding an interposer to the floppy controller IC to give an internal floppy connector, then remove the serial connector and bypass caps and make a custom bracket for the Gotek and mount it there, then maybe make some extension so the screen and controls pop over the top of the system. Thoughts?

I am looking to purchase a Tandy 1000 RSX computer.

With this all said, i am going to take a crack at coding my own game sometime soon, not sure how far I'll get, but you never now 'till you try eh?

I've been chewing on this idea for a 2600 game, pretty simple one actually, but I'm not a programmer..

Anyone ever get ideas for games and then realize you don't have the chops for programming?

Suppose I could do a Dpad, four buttons in a "diamond" layout ala SNES and have a mode switch that would do dual stick or fire buttons, but it would be more complicated electronically. I would have to figure out where to put an analog stick, but I want to keep the feel of the 5200.

The whole idea was to make something that looks like it belongs with the 5200, like Atari would have designed it. I may use PS or GameCube style joysticks or one I found that looks good here http://www.skycraftsurplus.com/0949rjoystickwpots.aspx If i get around to modeling it, I'm sure the shape will change some. I wonder if there would be any demand for it if I made some.

Well, if I had a 3D printer, I could print it as a solid piece, then I could judge how it feels. We have one at work that is just sitting, might try to nab it for some test run.

It's for the two or three dual stick games that are supported. One would either have to have like an 18 conductor cable and break out another 15 pin connector for the player 2 port, or add a TRS jack and let you patch it in to the player 2 port with a separate cable. The idea was to use an actual rubber keypad from a 5200 controller and just have it sit on top of tact switches. The same would apply for the three function keys.

Just something I drew up as an idea. it's not to scale, just a concept. I'm considering getting the ball roller on trying to build one, just not sure on trying to get the shell done. Anyway, I'd love to hear comments on it! 5200 controller.bmp

I have recently gotten a Vectrex with the white dot problem, except mine doesn't have audio. Sometimes when you turn it on, you will hear some odd sounds, but it's feint. All voltages are present, I pulled all the socketed chips and cleaned them, no change. the dot will also move from one power up to the next.

Anyone here do Coleco repairs/mods?

just reviving this to see if anyone has a power knob they could sell.

I've had some things come up, so I am not going to be able to buy that Coleco, retrolucid.

I wonder if any Z80 can be used in the coleco, long as it's 40 pin.

I am going to be dong them today online, so probably this week is when i would get it in

can you hold on until i get my tax return?
