Thanks Tupsu but you can not find this crystal in the market, that's why I asked a picture of the batch 1 qberty's bridge maybe we have chances to find it somewhere.... 'qberty' any chance to help us to fix your mess ?

Big problem I have in life is trying to figure out what the components on these boards *are*. I can make assumptions based on signal input/output, size, and overall position in the communications chain (for example the U204 components at the top left of the board. They are signal level converters, but finding them with a 3 character ID is a damn bitch). Likewise the crystals, the numbers on them don't seem to make much sense.
Anyone got good pointers to identifying these various components? I've pretty much fuzzed out the board, so we don't need the schematic so much as the bill of parts.

says "24.576" on all 3 boards -- which is a 24.576 MHz crystal oscillator(thx google) -- maybe it's just a bad batch of chips or bad soldering on this latest board -- maybe try soldering a different 24.576 chip and get lucky. Just a thought ... probably more to it than that
I just checked my board and it doesn't work either, so I guess we're all in the same boat
I also just checked my Neptune board and that did work as a titan controller, now back to needing another bridge board

Is that from a real KNC bridgeboard?

yes, it's real real small, needed 2 pairs of glasses, to double magnify it -- and it's on qberty b1 and b2

Not right now. I have two other projects on the bench I have to figure out first.

I can probably get an electronics shop around here to look at it, if the crystal is bad or cold solder it should be pretty easy to fix

I can probably get an electronics shop around here to look at it, if the crystal is bad or cold solder it should be pretty easy to fix thank you..I've been trying to figure out how to have the local Electronic Engineering Univ club look at it w/o looking like an 'electronic stalker' pssst...hey baby want to look and heat up the cold solder on my knc asic titan bridge...I come across as a 'cheap' nerd and really don't have an angle on what would be a fair price to offer to fix this ...pizza and beer to the EE club probably would not do it.....and I'd probably have to float it by the faculty......doubtful....others around here don't have the skills ..that is one damn small chip etc Again would like to find the larger grandfather of those chips before shrunk down to that size..and just do a rough protoboard with leads for 30-40 bucks plus these larger cousins......but again the skill level and time ....just don't see it let us know how it goes....I'll see if I can find someone to at least feel out on this at the local university (more weird looks in my life...great)

Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:)

Here you go searing, give it a try -- apparently the orientation(polarity) of the crystal doesn't matter -- but careful with that little SMD capacitor(C13) right next to it, don't want it to come loose too. https://www.youtube.com/watch?v=14fJTgFg03Mlooks like a piece of cake

I imagine any old off the shelf surface mount 24.576 MHz crystal oscillator will work, but I dunno for sure. The soldering on mine looks good to me, so not too sure it's a cold solder issue but can't really see the backside of it to tell qberty when are you going to do batch 3?

I doubt he is gonna do a batch 3 unless we get an angle on how to get the batch 2's to work....with me (2 I think?) and the two friends who I told who each got one (2) =4 that is 0.8 BTC BTC gone or at todays rate of 600 bucks that is $480 bucks...I just don't get it thou..his first batch stuff worked just dandy...I'm still running one... Well it is all down the tubes unless a fix/hack/replace is found...none of them seem to work.... electronic solder skills and or guesses on what is wrong are beyond my 'newb electronics' skill set ....(damn that chip is small) just saying You have an angle on what you are gonna try to fix on yours or are you sitting on hands too waiting for qberty to reply and or tell us a probably of a hack/return or whatever.. Want to keep them...need the dang 3 controllers so it is not about the $$$ ..that is a last resort for me....but needed these for some Titan Unicorn Boards

After thrashing Tupsu & KNCFUN for pointing out some of his little lies, now he's boxed himself in with some bigger lies ie, (a) he tested them before shipping (b) complainers just want free boards (c) we don't know how to plug them in (d) someone asked "nicely" so he'll make a video (where's the video?) If he'd offer some helpful info on what's wrong & how to fix them, nobody's going to care much about the other stuff -- then maybe try a batch 3 when the bugs are worked out I haven't taken mine to an electronics shop yet, maybe next week

I did test mine according to how qberty wanted me to ..with a pi pc power adapter to be safe...nada...so then regular test with working psu on a titan etc also nada... hopefully he is confering with the china clone maker that made the boards for some kinda fix or redress (a guy can hope) drama crypto always drama
