Well figured out where the issue laid. One of the chips on the cpu board was bad. I for now just swapped out the cpu board but as I get time I will swap out the chips and figure out which one was bad. But on the plus side the HCD eng dept system is up and running

the external pack to the wall. I had 2 of them available and bounced back and forth and no change.i dont have a volt meter to check things so been trying to start simple and work towards the harder fixes

the power supplies themselves

Im trying to diagnose and repair that 800 i bought from one on the members on here. The one with the unbadged 800s. ( I bought the one with the engineering lab label on it.). Anywho. Ive gone though the usual suspects for no video ( not even getting the red screen he got when he made the post since he was having a video problem ).so kinda lost why now i cant even get that. Right now getting a black screen a little bit rolling sometimes and a hum/ popping sound from the TV. Ive tried : changing and clean the ram rom chips. ( the ROM had grease/petroleum jelly on the pins that went into the slot ). I cleaned it off and such . No luck. Changed the ram chips. I need to get a spare 10K rom chip to try that. Every chip on the board is socketed. so i tried to reseat all the chips. checked for any bad resisters or capacitors, none that i could find bad swelling up or leaking. Changed power supplies, changed video cables. nothing gives me at least the red screen that was shown in the picture. Im thinking maybe if i get a different ROM chip maybe or it could be a bad CPU or video chip on the board that needs to be swapped out. Im not sure where else to go with it. Just thinking from easy to hard how where do i go from here. Extra Rom CX801 is the next easy step before swapping chips off the board. but what else should i look for.

If you need brown shells with metal backs send me a message i have a bunch available.

Prefer loose since on the carts

Also looking for Silver label Defender Eastern front 1941 Red label the learning phone. Grey cart silver label Pacman Joust Tennis Ms pac man And Moon patrol

Any photo of the 3d ttt cart?

Looking for these cart onlys. Please let me know if you can help me finish the last 2 carts.

Following

I've seen either best or video 61 do that for basic. I forget which one interesting to see they did others too

Anyone willing to part with 1 of the 2 copies of the game. I doubt it but figured I'd just come out and ask lol

Theres mt salt 2.05 with my 2.07

This is a great idea. Easier to keep track of clean up when done.

Nope a guy on here had a few 800s he wanted to know more about this happened to be the system he sold that ended up in house and from what I gathered might have been a dev console ( loosely used term since it was used to test eprom prototype games on cart and disk) . The HCD label on the front shows it From the info gathered this system was in the home computer division dating to September of 1982. According to one employee at atari at the time. What I'll never find out is how soon after the 060 date code did the aystem find it's way into the programming lab nor how long after was it decommissioned from that division. Not much more info is known about it's time at Atari. He has a few other things I'm interested in but hasnt parted with them yet.

Heres my newly added 800. 060 0501 ( 6th week of 1980) system that was talked about on here.( the atari h.C.D. system) Went to auction and I plan to fix the video so it will live on happily playing the arcade classics.

Message sent . Let's talk

Thanks for the look out. Sent you a message earlier today also. Gonna follow the auction

These are really cool. At home I have the atari phone directory on my desktop. When I go home I can search through it . Should be able to tell me what department that person was in.

Hi looking for the following carts for the xegs blue labels Lode runner Thunderfox And summer games Please let me know if you have one available for purchase. Thanks Jason

This is cool. I have both systems and looking to expand my collection of each. What would be the must haves / must plays to get going for someone in the US?

Last 2 carts to come in were for the atari home computers. A prototype / reviewers copy of sky writer rev.1 Serial . 18 And a PCB of the ERIC ( electronic retail information cart)

I just got home today from work and had a few Atari 8 bit computer cart friends waiting for me. Atari Salt Vers. 2.07 Atari Super CPS FD100335 ( has Atari Print typed labels for Qix Rev 0, Basic Rev 3, Word Wise Rev 1, and Atariwriter Rev 3). Atari Plato STD Version ( with a date of 2/9/84 crossed out ) Atari Writer Rev 7 Serial 48 Letter Perfect 40 by LJK ( Thanks again FND for the cart ).

Chris I sent you a message. I hope you remember me please let me know what we can work out.

Can a few people put a few examples of the brown basic cart board and masked Rom chips for me to inspect. I'm doing a bit of research in something I pretty much know the answer to but would like a few masked Rom examples from the brown basic cart for comparison. Thanks in advance
