My secret Santa package arrived last night! Well some time yesterday and I grabbed it last night. I only thought it might be my secret Santa based on the Happy a Holidays sticker. I went to open it because I've ordered a ton of stuff online for various reasons and forgot a bunch of it. When I opened it, I saw there was a card and a bunch of candy inside. I closed it right away. I want to open it on Christmas when my family opens theirs. I don't get a bunch of stuff for Christmas like they do, so I have something to open with them. I also enjoy a good surprise. Thank you, secret Santa!

I've played a lot of botw and I've never heard the deku mention anything about UPS. Also, I hope my recipient is as excited about personalized hand crafted items as I was about making it.

Bought a boxed neogeo pocket color and Metal Slug from snkammar and the transaction was super smooth. The box was packed really well and made it with zero issues. Would absolutely buy from them again.

Was watching the newest episode of Stargirl (season 3 episode 11) and noticed some paddles on a desk in one scene. They were not mentioned and I didn't see a console in any of the other frames but I may have missed it.

Tomorrow is my bday so I wanted to give some hefty price drops in honor of the deals I've been given myself. Free shipping on the SNES and colecovision. $100 each with free shipping. CTR-80A marked down almost in half. Removed sold items too.

Added want. Looking for a Sega CD model 2 PSU.

@3DMAZE perfect. Thank you! I saw that one too even when I was looking but the shipping makes them cost around the same for the same amount. Honestly I'll probably be better off just buying a few right now so I know I have a good set, and checking the rest of them to get a good set in the second console. Maybe I'll buy 5 as well. Here is the model 1 that I have: Would this be like the one you referred to as a 1.5?

Thank you both! Excellent starting point to get roaring on. I'm not familiar with different types of packages of chips. Would these work? https://www.ebay.com/itm/175404085893?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=dQGtIlKTQ86&sssrc=2349624&ssuid=tc6gnTeJTDi&var=&widget_ver=artemis&media=COPY

Ok at this point, I believe it to be bad RAM. Does anyone know where to source ram or a ram mod for the Channel F? I've seen multiple posts about ram, but nothing conclusive. There were actually a few quite contradictory. Has anyone here successfully replaced ram that was not sourced from another console? If so, can you point me in the right direction?

As in one that does not require batteries, or one that has been modified for use without batteries? Send me a PM either way. I think I got a bunch of stuff from you in the past for the n64. I can return the favor.

Bump. Few prices dropped.

Also looking for BIOS chip for a channel f. I'm about 99% sure that's the problem I have.

That makes sense. I can't find the thread now that mentioned carts should boot without it but I know I read it somewhere when I was trying to find out info. I should have bookmarked it. Oh well. The only other console I have access to right now is a system 2 and that chip is not socketed, and is under the cart slot mechanism. It also appears there's only one chip for the PSU on the system 2. Man. For being an early system, they sure used random parts and board variations. It's weird, especially if the bios are all the same. I'll look again in the system 2, and see what happens. I really hate to desolder 2 of those suckers just to test. Plus the system 2 has garbled graphics so it's not for sure those would even work.

Ok so they don't need to be replaced in pairs, but would a part 2 of the 2 part PSU from another part number be a suitable replacement? Example: The bad one is 90026 (I'm guessing can't replace with a 90025) But could I replace it with (something I'm going to makeup here because I don't know) LS91026 (as long as it coincides with a 91025)? Or must it be an exact LS90026 that I replace it with? At this point I'm sure it's a bad chip. The 90025 in the system does not get hot. All chips receive the accurate voltage according to the diagram I found for each. They all put 12 & 5 volts on VCC and VDD (I think it is). Even there bad one gets the right voltages. This is why I figured the chip itself is bad. I'm hoping someone here might have a spare from their own parts console. Edited to clarify part 2. I assume 90025 is part 1 and 90026 is part 2. I read somewhere (I'll find it again if necessary) that carts work without the onboard games chip and that the specific chip was the PSU set. Are you absolutely certain that nothing will work without it?

Does anyone know if a cartridge will bypass a bad Program Storage Unit in a system 1? I have a system 1 that I believe has a bad PSU (program storage unit in this case). The chip is labeled SL90026. From what I can tell, this and 90025 are the chips that hold the built in games. Can anyone confirm? I think this chip is bad because it gets REALLY hot. Too hot to touch for a good while after it's powered off. Also can anyone fill me in on if these need to be replaced in pairs? If I find another sl90026, can I swap it in? How about another part number but also the first chip in the program storage unit set? I get a black screen and nothing else. I do kind of hear a splash of static from the speaker but only for a second at boot. I have zero cartridges to test the theory. Anyone have a spare that isn't very popular?

Interested! Waitlist me please.

New want. Thanks in advance

No because it uses some of the circuitry built into the RF modulator. No idea why, but when I was looking for a solution to poor RF, I found that most or all Colecovision video mods won't work without the RF unit installed. There might be one solution but I can't remember. I know I made these because it was the most economical and clear video mod I could find. There are much cheaper ones, but they burnout and fail. This one will last the life of the console. Plus, you don't have to remove anything from the console and there are only a few connections to solder. But yes, it will work even though you have poor RF. That's the exact same reason I used it. Here is what it looks like on my TV sets: CRT: LCD:

How about an lm318 mod board? I bought enough to make 3 (minimum oshpark order) but only used 2. You can pull the signals from here: If you want to make your own, I found the board here: https://oshpark.com/profiles/thecrypticodor If you want, I can send you the spare board I have. It's already setup, the one in the first pic. $10 plus shipping.

New want. Would love to make a trade.

Oh man I would love to give at least one of these a try. I have a few 4 switches and a Junior hanging around (all NTSC). Would love to see how this fits with the RF shield around the whole thing. Seems like there is plenty of room. So since nothing is removed, this works similar to the UAV where you can still use RF if you want?

We talking original Odyssey, or Odyssey 2? I have a spare O2 that we can discuss. I got it as non working and have since repaired it. I have one that I did myself, and one that I let me kids help me work on. Both work great but I only need one at most.

Well apparently he 2600 junior I had on OfferUp for as long as it's been here, has finally given me a lifetime ban from OfferUp. That's fancy. I guess it was my bad for including the SD card with the Harmony. So if you are interested in the Atari, for legal reasons I guess I am not allowed to include any content on the SD card. You will get a blank SD card and will have to add your own content. Oh well. It's not like I ever actually sold anything on OfferUp. Everything listed there has historically sold somewhere else.
