NES CPU, PPU and RAM Testing - Socketed NES System - Fixing Ebay Junk

- Опубликовано: 6 апр 2020
- Today I make use of the Socketed NES board I made to test the CPU, PPU and SRAM chips I pulled from the old nasty NES Toploader I was working on a long time ago.
Using this, I'll be able to continue trying to repair my NES Toploader.

I highly recommend storing chips in either static safe foam or bag. Keeping them in a regular plastic bag like that can cause ESD damage and ruin them.
The plastic bag is probably not as big a deal as you think. Ideally you’d stick the IC in some anti-static foam first before putting it in an ordinary plastic bag, though. - A sheet of plastic doesn’t magically generate static electricity in and of itself, although holding an empty bag between your fingers and rubbed the two sides together might do it.
ZIF connectors and anti-static bags would be my recommendations. Both would prevent a lot of undue damage to your chips. :)
The Zero insertion Force (ZIF) socket really seem like a good idea since you might use this test console often. Nice video as always ^.^
Theres that intro, its like a cold ice tea after a hot day mowing the lawn, good n’ refreshing!!
i realize I'm quite off topic but do anybody know of a good website to watch new movies online?
@Jaxon Caiden Lately I have been using Flixzone. You can find it by googling :)
Respect for showing your mistakes. Mistakes are common even when you know what you're doing
What we have learned today: coffee first. But I like your NES with those socketss. Thanks for this interesting video.
Always something interesting to upload, eh bud? I think what gets me pumped for your videos is firing up the home theatre w the bass up, for the intro to your videos. It's a good time! I recommend it for anyone who hasn't heard/felt it at high volume/bass. :-D
Very informative! I like the idea of a dedicated, socketed machine for easter-egging. All good wishes during the Zombie Apocalypse.
Very interesting! Nice to ear too that you’ll finish the top loader
Have you considered a Soldering Playlist? Where you show how to solder and desolder? I guess could be interesting for some people. Keep up the great work.
That toploader vid was the first iof yours I ever saw!
Have you considered using ZIF sockets in your tester nintendo? I am guessing they wouldn't fit in the case real well, but if you are just using it for testing chips, that might not be necessary. Of course, they might not fit on the board, because they tend to be bulky.
Love your videos
nice video as always
i dont really repair that many NES consoles but i NEED to have that tester 😂maybe, if you havent already, make a video on how to make one for other consoles? (N64 etc.)
It's easy to make for consoles with "through-hole" parts like the nes, cause all you need to do is desolder everything and then put them back in a socket. The N64 uses SMD and you'll need special equipment to even desolder the chips, let alone soldering the sockets
Pretty much all this.
Sockets for smd chips are more difficult to install and much more expensive and harder to find.
Nes and older is no problem.
@@RetroRepairs oh yeah but wouldnt it be a fun and interesting video? the worlds first N64 chip tester? ;)
JuicyJake Repairs you would need special QFP sockets and they’re expensive but, this socketed method works well for other older consoles. I even socketed an NES cart to test RAM chips for cartridges, most NES games use a generic 8k SRAM chip for WRAM and surprisingly even the CHRAM.
N64 doesn't have that many chip problems to bother. Fixed a bunch of them and rarely if ever was it a chip.
Any update on the Sharp Twin Famicom?
Thank you so much for not editing out some of your mistakes. It helps so much to know silly things happen sometimes and it’s not the end of the world.
God I had a good laugh for the first minute and a half. I can't tell you how many times I've done that, not plugging the power supply in or the main supply cable for the power switch.
At least you showed what would happen if you swapped the ppu with the cpu cool, interesting if it had worked and bypassed the nes lock out chip.
I'd be curious as to what other cpu's in that form factor could be used to replace the original, not to over clock unless this is possible I'd want a throttle switch for rpg games that require hour's worth of xp farming. It becomes tedious on some games, however it's my escape from migralepsy.
Im not sure if there's a drop-in substitute, i know there are some reproduction parts that exist, but this chip I believe was a custom modified version of a 6502 processor, which itself is fairly common in older stuff like ataris.
Hey thanks for the video.
A crazy idea: what about cutting a sort of latch panel on the bottom so that you can access the motherboard without taking the nes apart everytime?
I dont like that idea for a couple reasons. One, you'd destroy the shell, and 2, there's some ribs onthe shell that provides supports for the system to be mounted to, I'm not sute how easily that could be done.
I figure for the limited amount of times this will get used, I'll just take it apart
@@RetroRepairs true, still you would not be cutting through the whole case, as the chips area only covers a portion of it.
Preserving the case is a legitimate concern as well.
@@RetroRepairs If you were going to use it a lot, you could just pull it out of the shell entirely, and get a custom shell 3d printed that gives you easy access. It'd cost some money, but then again I don't know how often you need to troubleshoot Nintendo CPUs.
Oh yeah
Be sure to disable the 10NES lockout chip.
No need
how to know if my NES is bad with these chips? I've tried to fix it with 4, 5 videos over here and I can't make it work! I own another NES working completely fine and I tested its seventyandsome pin connector into this faulty one. All I get back is a big white, grey, blue screen. Is it the main capacitor? The chips? I dunno :/
Well. If you use that system only for testing, maybe you should just sing the game directly to the board?
Where did you get the chips.
I have audio and video but all the colour and pixel is messed up do you know what it is
Isnt there sockets that have levers for holding the chips? Looks like you are using a lot if force to remove them.
Great video btw
Yep ZIF (zero insertion force) sockets, but they are taller than regular sockets, on the other hand they make working with chips with bent pins easier.
They also start at £8 on Farnell.
@@bufordmaddogtannen Thank you. I am all new to this and learning much from these videos
@@woodysgeekchannel2204 my pleasure.
And avoid the cheap knockoffs. Yes, they make crappy ZIF socket knockoffs.
@@bufordmaddogtannen Adrian of Adrian's Digital Basement did that to a c64, and he wasn't really able to socket everything on it. I was thinking (and commented separately) that doing something like that might be an interesting option, but I don't know that ZIF sockets would fit really well on that board now that I think a little more.
Adam what type of tool are you using to pull the IC's out of the socket?
It's called a chip extractor or IC puller
@@RetroRepairs ty I'll chase one down on Amazon.
Check your email sometime plz
Hey Adam quick question...I have a nes that had a blinking green screen I cleaned the pin connector and the game but it would not work?
Do you have other games to test?
Sometimes the pins get loose and just physically don't make a connection anymore. The pin connectors will actually need to by physically adjusted sometimes
@@RetroRepairs yeah I tried a few different I want to just giving up any idea what that green screen means
Can i ask what your background is( education, career,) your very knowledgeable.
Went to university for business. Pretty unrelated to this stuff
Where can I buy a NES CPU,PPU and GPU??
I blame Nintendo for designing the NES to use very similar PPU and CPU chips
Im guessing it helped with cost savings
