I got a 7800 two weeks ago, I just did most of the things you did in the video. Picked up a Game drive as well. Atari is selling reproduction official gamepads for the 7800 because of the 7800+ releasing, I picked up one of those and it feels really good.

I lived that period of time and EVERYBODY lost the included power supply right away. Thing is this was on the main and only tv's and mothers would make us unplug and put it away each time she wanted the tv. And so we all ended up using those multiple voltage power supplies from Radio Shack. 5v was 13v, 9v was 27v, and 12v was 43v. I can't believe they worked anyway with these garbage power supplies. My 2600 now runs with a buck converter on a switching power supply. Its happy. EDIT* Back in the old days, power supplies had no voltage regulation at all. It was 100% voltage multiplication. The chinese factory worker would count the turns of copper wire in the coils according to his guesstimation.

I can't believe the protective plastic is still on. That RGB cart looks very interesting.

[@LeftyLabs]

The 7800 GameDrive is amazing. “RGB” as such isn’t very common in North America but the cart output is also compatible with Component, which is similar to RGB and used in a lot of NTSC TVs from the mid 90s through late 00s. I’m using it with a 27” Toshiba CRT and the video quality is great.

59:45 plug the power supply 180 deg the other way or "upside-down" so it's not covering the converter and you can cool it better. The plugs are clearly not polarized so it's fine.

Top tip. 👍

13:00 Heh funny, just got one of those, got one to use my SMS gun on the 7800. Yeah largely I think an FPGA flash cart solution is likely one of the better ways past the POKEY limitation, homebrew authors should do a ROM sale option along with the stand alone carts. Got to get back to my 7800, need to find a final solution place for it other than occasionally out on the carpet heh.

There are special tools for turning those pesky metal tabs, they look like screw drivers with a slot in them. Ideal for the hard to reach ones. (no idea what they are called)

[@EgonOlsen71]

The Atari 1050 disk drive used a 6507 as well.

[@samt4202]

I wonder if running a transformer meant for 60Hz on 50Hz is putting more strain on it and it gets hotter as a result. Also it is possible that their is some sort of magnetic coupling between the two transformers that is causing it to heat up as well due to the them being on top of each other.

[@frankowalker4662]

45:02 there is some smoke that looks like it's coming from the resistors below the cartridge slot. But on closer inspection at 45:00 it seems to be coming from under the desk. Could that be the dropper transformer ?

[@GadgetUK164]

I honestly cannot see anything lol - I will watch again!

[@frankowalker4662]

@@GadgetUK164 Just looked again. It's right when you say 'I'll just get the multimeter out. Just gonna mea (smoke) sure..' You should see the first bit of smoke against the black plastic at the right hand joystick port. Then it drifts up to the cartridge slot. It's easier to see at 1/2 speed.

I've seen plenty of worse-looking 16 bit games!
