Well, someone asked me about the Kaneko Super-Nova sound fix, and while the information is public it's not widely publicised. Rather than just detail that one fix, perhaps people could post links to their PCB repair logs in here, if they have one.

Here's mine - there's nothing too spectacular in there, but....

Apologies if incorrect terms are used, I was very much in the early phases of learning when most of this was done.

These are logs/forums not by myself, but by others.
If I missed the point of this sticky please remove this reply and sorry for the trouble.

Hi everyone!

All my repair logs are here: http://newlifegames.net/nlg/index.php?board=19.0

They are sorted by manufacturer and I hope they help you keep your systems running!

Enjoy

Oh my... great stuff channelmaniac!
That page got instantly bookmarked.

Do we have a UK PCB repair guy who is reliable?

Without wishing to blow my own trumpet, I'd say that i'm reliable. I'm sure others here (and on Arcade Otaku where I post under the ID of Vectorglow) would vouch for me.

I hope!

Other repairers are, of course, available. Channelmaniac in the US is very good, as is Tim Matthews and P-Man.

Tim doesn't repair them for money though.

Also - I updated my repair log, the online version was quite out of date.

Just going to pop my Raiden DX board fix in here. Brought this baby back from the dead!:

Although still learning and doing basic ones, I decided to document the ones I've done so far. They are in Spanish though, since there are so few resources in that language. However, if anyone ever wants some translation of anything, I'll do that gladly.

I've updated my log again - starting to tag the hardware type (where known) in a column to help people searching for repairs to other games on that family.

Hi, I've done plenty of rep logs since I posted a link to my blog many months ago.
One or two people from here have asked me if I would post in this thread every time I make a new rep log. I'll be happy to do so, but is that a general wish, or is it just a few ones?
Don't want to be known as 'The Flooder' };-P

I just mention it from time to time. Since I last posted there were loads of new entries.

Okay.
I've have made a lot of new entries on my repairs blog since I last posted a link (20121010). This includes some nice shmups, retrofitting an USB-port on my Fluke9010A, and also some Amiga-stuff (as I went a little Amiga-crazy for a short period };-P).
Please feel free to have look around, and also leave comments; love when people do };-P

PS: Love the stuff you're doing, Artemio...pitty it's in Spanish...however Google Translate is my good friend there };-P

Thanks! I am honored since your I have been an avid reader and fan of your blog for quite a while via google reader.

I've been slowed down by an R-Type... Didn't boot every other time, no audio, corrupted backgrounds, corrupted sprites, problems in the scroll, and the last issue I am tracking is vertical red bars in some layers... I don't know if I'll be able to recall everything, so far I've replaced 14 damaged TTLs.

I'd love to get a Fluke, a shame it would be way too expensive to import to Mexico.

Keep up the excellent work, I read all your posts and relive them =)

Thnx for the kind words. And you too, plz keep up the great work };-P

When I get stuck with/sick of a board, I often put on the shelf and do some other repairs.
Then you can pick it up again after some time, fresh in mind
...I very rarely work on only one project at the time };-P

Yes, it is hard having only one stubborn board on the bench. However with this one i had so many "this must be it" moments that have been partial fixes, it has grabbed me and is exhausting at the same time. I do have two other boards that I am "working on" at teh moment, but I really haven't since I feel i am so close to finish this one (and I want to play it).

I should leave it fro a while.. it has slowed me down indeed.

Damn, know the feeling. I have an original R-Type myself, that I've had under the knife at least 3 times without being able to fix it };-S

Those can be hard to diagnose, much easier of course if you have a spare M72 set to swap boards around with. I've had problems with several M72 lately, and all but one actually came down to bad connection on the ribbon cables, or bad contact on the top board jumpers.

Yes, I've been reading your logs too.. there is not much information regarding the M-72. Thanks a lot.

I do have a Gallop at hand, without it it would have been a real nightmare. All there boards on this R-Type had issues:

1) Rom board had faulty 74ls245 and RAM
2) Main board had faulty 74ls74, 74ls245, 74ls244 and a few others...
3) Bottom board had faulty 74ls283 and 74ls273, and some more I haven't found.

With the Gallop boards I fixed one at a time. They are indeed hard to diagnose due to them being stacked. In some cases I could determine the faulty TTL by proper diagnosis, like the faulty flip flop in the audio or the adder in the scroll.. but since the bus has data and address lines in this CPU, it was quite difficult to figure out the 245 and 244s, my lack of experience didn't help there and I had gotten used to diagnosing 68K ans Z80s...
