    That's awful looking initial soldering, as has been said, a thorough cleaning and some jumper cabling should do the job.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    I think I'll stick it under the microscope again and have a look around the board for any other soldering travesties.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    Raspberry Pi Pico W in stock for those looking for one(or 10). I grabbed a few for myself for a few upcoming non retro projects.

    Question for those more knowledgeable than me, would lead-free solder paste be ok to use in general retro console/machine repair/maintenance work? I have something in my mind from reading stuff about not mixing unleaded solder with leaded solder...but maybe that's advice for not physically mixing them on the board? I'd obviously be desoldering, braiding, and cleaning with IPA before applying lead-free paste...



  • Registered Users, Registered Users 2 Posts: 2,030 ✭✭✭Colonel Panic


    Mixing them is supposed to be bad due to slightly different melting points causing poor joints. On a completely connection, there's nothing wrong with using lead free solder if you want.



  • Registered Users, Registered Users 2 Posts: 2,030 ✭✭✭Colonel Panic


    Did a PicoBoot install on a DOL-101 just now. Very simple although some of the connections a bit awkward if left handed.

    Works perfectly!

    Speaking of... guess what I'll be at tonight?





  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Boom. That was easy enough even for a relative novice such as myself.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    I've got that mod lined up myself.

    The Pico boards are very versatile little things. I've only really started testing them out for a few projects recently and so far it sort of clicks with me more than Arduino ever did. Testing a simple webserver/mini wifi access point to control some LEDs at the moment to see what kind of battery life I can expect.





  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    A question to the soldering experts(I know you're one @Inviere 🙂). Do we need to tin the tip of smaller soldering heads/tips? Or is that just something for the larger ones?

    As in this video, he tins the tip, but its a fairly beefy one and not something I'd use on small electronics.


    I no expert on soldering and have never tinned them, just kept them clean with the brass cleaning ball base(the pot scrubber looking thing) as well as using a small brass wire brush to scrub any extra carbon off them.

    Thoughts?

    Far from a soldering expert me, because the above is something I've never heard of before! I've heard of tip rejuvenation paste etc, and good practice like cleaning with solder brush then flowing some fresh solder onto the tip when you're finished with it to prevent oxidation during non use....but tinning new tips isn't something I personally do (though it does seem like good practice!)



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    I'm trying to do a bit more soldering these days as it's just not a skill I'm very proficient in. So I want to get it right, even if its just soldering on some headers to a raspberry pi or something basic like that.



  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    Kinda depends on the type of tip your using, if its a conical tip then I'd just wrap the top 3-4 mm of it as you want the whole tip to be a working surface. But for a bevel or chisel tip I'd only ever tin the sloppy working surface side as thats where you want the solder to stick to rather than flowing around the back of the tip.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    I think I should probably invest in at least an entry level "decent" soldering station as what I have at the moment is an Antex soldering iron(its ok) and a cheap Tabiger kit from Amazon(again, ok when used with upgraded tips).

    I'm currently looking at the Hakko FX-888D(€103), Hakko FX-951(€280) and the Weller WE1010(€128). The Hakko FX-888D seems decent for the money and reviews well. But I'm open to advice from people more knowledgably than myself in this.





  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    I've a Hakko FX-888D for a few years (was a lot more expensive when I got it) and its been flawless so far and has gotten a lot of use. Only use genuine replacement tips though as the cheapo ebay ones are pure crap.



  • Registered Users, Registered Users 2 Posts: 2,030 ✭✭✭Colonel Panic


    I use a Hakko FX-888D and a KSGER T12 (AliExpress special) as my two main soldering stations.

    The Hakko is definitely what I use most of the time and I certainly recommend it. It's user interface reminds me of the kind of nonsense you used to have to do to program VCRs but once dialled in, it's a great piece of kit.

    The KSGER is a decent iron, but I only kept mine over the Hakko as it arrived with bad solder joints on the power supply connection (the irony) and I got a refund and fixed it with my Hakko!

    It's unfortunate that they use different tips by default. I tend to keep chunkier tips on the KSGER.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    I’m leaning towards the Hakko FX-888D. Looks to be a neat setup as well and the price is definitely right.


    Edit:

    Went ahead and ordered the FX-888D, 8 Hakko tips and bunch of other bits. Came in about €200 which is pretty good. Ordered from the same place I got my rarely used oscilloscope, so I don't expect any problems or fake equipment(which it seems is common with the Hakko stuff).

    Anybody got any experience with Xell Reloaded on a Trinity board?


    I'm in the process of trying to RHG my Trinity Xbox360s with pico flasher and I'm having a bit of trouble.


    I've backed up the nand using jrunner, created and flashed ecc but the console won't boot!


    It'll start up but no video is output and it won't join the network.


    I've tried reflashing numerous times but nothing.


    I've checked all solder points for continuity and they all appear to have it.


    Any idea what I might be doing wrong?


    I'm going to redo the solder points just incase.


    Thing is, pico flasher can definitely communicate with the nand read / write to it so I don't understand what's going wrong.



  • Registered Users, Registered Users 2 Posts: 7,759 ✭✭✭Inviere


    Been many years since I messed about with 360 modding (the jtag days), but might there be something wrong with the image you're flashing? Or thr nand dump itself?

    I remember you had to dump the nand more than once, and compare the dumps to ensure they were correct.

    I do want to look at an RGH mod at some stage, on a Trinity board I believe.

  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    I've done a couple of Trinity's without any problems, with whatever the latest Jrunner at the time was. Did you try different timing files ? And booting by pressing Eject ?

    Are you doing RGH 2 or RGH 3?



  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    I'm an idiot. There's an entire part to the guide that I didn't finish! It has RGH3 on there now but turns on then just powers off.


    ...because I accidentally haven't linked POST, SMC_POST SMC_PLL and Bypass.


    I need a 3k resistor though which I don't have. To Amazon!


    I hope I haven't ballsed it up. Although I suspect that it's powering down when trying to glitch due to lack of access to... whatever it needs access to.


    To Amazon!



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    My Hakko FX-888D arrived this morning from the Netherlands. It's a big step up from the cheapo Amazon irons for sure, and the silicon cable wrap on the iron itself is something I'd never thought of, but makes it way easier to move around without the cable becoming a problem. Did the checks most people recommend online and its not a fake or very old stock(manufactured this year).


    Also got a few rewritable NFC tags to test for a little cataloging and security project I'm planning for my retro gear. The below tag is the smallest I could get at a reasonable price that can hold a usable amount of data(144 bytes in this case, which is enough for my needs).


    And not directly retro related, but my Flipper Zero arrived yesterday after a 2 year wait. It can do a lot of cool nerd stuff once you know how to use it. I have a few retro projects in mind for it once some of the GPIO stuff I see people working on come out. For now I'm just playing with the Sub-Ghz, NFC and RFID side of things with it. I'll probably tell my neighbour it was me accidentally opening his garage doors about 10 time yesterday :)




  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Oooooh that flipper certainly has... interesting uses. :-P


    Off to go clone some hotel keys are ya? :-D



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    Not done keys yet, but I did a few Amiibo tests from ones I own and cloned directly as well as downloaded. All works fine. So many uses for this thing, both good and evil.

    Remind me never to install anything with an electrically controlled lock!

    Just watched some videos, that's a really cool device and the type of thing I love messing about with, will have to pick one up!

    Yeah its a pretty cool thing. Even the Infrared stuff is turning out to be more useful than I expected. Definitely worth the money, but maybe not the 2 year wait 🙂



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    Is the TL866II Plus still pretty much the best option for burning retro rom chips(with the various adapters)?

    I'm looking to pick one up, but if there's a better option out there that people are using for under €200-250 I'd love to hear it.




  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    I got one of the older versions of the TL866 and a GQ4X. Both are very good but have their own advantages & limitations.

    First one I got was the GQ4X a good few years ago to program Amiga kickstarts and it comes with the correct adapters for those EPROM types. Used it for loads of different PROM/EPROM/Flash types, its doesn't program GALs though which I why I bought the TL866.

    The TL866 doesn't directly support 27C400's (Amiga kickstarts) so you need a custom adapter and use device type 27C4096 instead I believe.

    Software for both is pretty crap, the TL866 does have a opensource cmdline 'minipro' which is handy when added to vscode to do build-flash in one step for dev work



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    Thanks for that info.

    I see some TL866II bundles with a load of adapters included for about €100-150. Only problem is they seem to have about 10 different brands and I'm not sure where to buy them. Ali looks dodge for them, Amazon has them but not many reviews. RS do have them, but its nearly €300 for the device on its own there.



  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    Ah they're all the same really, definitely wouldn't be paying 300 for it though. None of the supplied adapters with program Amiga roms, you'll need to get something like this as well

    This is the one I purchased back in 2020 after purchasing another eeprom programmer that I thought could do the job but couldn't.


    Was only £40 at the time but they seem to have shot way up in price and Wingoneer don't seem to be doing them anymore it looks like. Try to get the original XGecu TL866II Plus if you can... but really even the clones will work fine. Infact I used it just the other day to program a Duke 3D repro for a friend that I'm visiting in NYC in a few weeks time.


    They work well with one of these bank switching adapters for Mega Drive for instance:

    https://www.ebay.ca/itm/284253939959?hash=item422edae8f7:g:IqcAAOSw1uJgk5cG

    Works well for burning Sega Naomi bios chips too.

    I would say don't go mad buying a bunch of adapters but at the same time they can come in handy too as I used one for a PIC chip a little while ago to create a PS1 modchip.

    Definitely don't go spending mad money though you should find a reasonably priced one on AliExpress or the likes, and like The Last Bandit said they're all mostly the same as long as they're TL866ii or so.



  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Wait, looks like Amazon DE have it for a reasonable price:

    https://www.amazon.de/-/en/WINGONEER-TL866II-Performance-EEPROM-Programmer/dp/B07B985LBS



  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Ohh and also I've noticed a weird quirk with mine, not sure if it's unique to my particular unit or not but it point blank refuses to work correctly if I use the USB ports on my PC that are at the front.

    I have to use the USB ports on the motherboard itself for to read or be detected by the XGecu software properly.

    Sorry for the post spam, I don't appear to be able to edit previous posts.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    Thanks guys, I had a look around and might risk the newer T48 (TL866-3G) direct from XGecu. VPP Voltage goes up to 25v, which is something I might need in the future(TL866II maxes out around 18V).

    I just need to do a bit more research on it now to make sure it will work with what I need. It seems fairly new, so not many independent reviews of it.





  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    Well it is "Cool and Portable" :)

    I've been trying to improve my soldering skills and was getting bored of desoldering and resoldering old pc motherboards, so thought I'd give those simple kits from Amazon a go and actually make something.

    The games are junk(Tetris is sort of serviceable), but that's not really the point. Was a nice fun one to make and ended up with something the kids can play with. Probably a bit too simple to be honest, but it got me soldering today so at least there's that. Solder isn't super shiny as its lead free and the flux I got seems to take the shine off it if you use a bit too much(which i do).

    I have a good bit to go before I'd be happy to do any serious work inside any of my retro gear, but practice makes perfect and all that 🙂





  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Welp... I couldn't get the RGH3 hack to work on the Trinity. That Trinity I bought was in awful condition anyway so I've decided to just add it to the e-waste pile along with the other Mega Drive that I messed up.

    Heading out later today to pick up a phat Xbox 360 which should be a little easier to work with. Nabbed for only a tenner on adverts so definitely not breaking the bank.



  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Sooo I plugged in the Xbox 360 and it had a red ring. Nooo! Wasn't the typical three red rings though just the one which is "hardware failure" but not "general hardware failure".

    Disconnected the hard drive and it booted straight up... so took apart the hard drive caddy from the Trinity Slim and rehoused it in the oldstyle phat case.

    Works a charm now, just need to update it to the latest dashboard and wait for some zenner diodes to arrive tomorrow so that I can attempt to RGH3 hack it now that I'm more familiar with the process.

    I picked up a couple of m27c512 EPROMs the other day and one of them just will not erase in my UV EPROM eraser. The other one erased fine after about 15-20 mins and was usable, but this one chip just holds the old data on it, even after 1 hour in the UV chamber.

    I took some close up pics in case there is anything physical that's damaged and visible through the window, but it looks fine to me(all internal pins/connectors seem to be hooked up and unbroken).

    Anyone have a better eye on this and can see an issue I'm missing? I know it might just be a dodgy chip, but if I can save it it'll make life a lot easier as I don't have spares of this chip type, just the amount I need.





  • Registered Users, Registered Users 2 Posts: 7,759 ✭✭✭Inviere


    No knowledge on the subject itself Steve, but the photography is class. Amazing to see those details. If I were to throw a blind guess, I'd say just a faulty chip given the other one erased successfully.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    Yeah probably dead and that's it. Just weird that its holding the data already on it completely intact, even after the UV.

    I use the microscope quite often these days for fine soldering, it takes a decent pic compared to my older one. The 10 inch screen is a gift for the soldering and general up close tinkering.



  • Registered Users, Registered Users 2 Posts: 3,725 ✭✭✭The Last Bandit


    Chip look genuine, you can try to alter the programming options to see if it helps.

    Disable the Blank check, Skip 0xFF and Verify options and increase the pulse delay time, this will force a programming cycle.



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    I'm using my old cheap no name USB programmer I got years ago while I wait for the new fancy one from Ali. I'm not sure I have all those options as its not a GQ 4x4 or TL866II. Maybe when the XGecu T48 arrives I'll have better luck.



  • Registered Users, Registered Users 2 Posts: 9,245 ✭✭✭MrVestek


    Some chips will honestly take hours to erase properly, especially a 512 chip.


    Leave it in the UV eraser for a period of 24hrs then try it.

    Anybody here use/build a TZXDuino? Just wondering if it's still the best option for cassette games....seems a bit of a minefield out there - TZXDuino, TZXDuino Reloaded, MAXduino....



  • Registered Users, Registered Users 2 Posts: 8,891 ✭✭✭Steve X2


    After watching a couple of videos from Noels Retro Lab on YouTube I decided I needed one myself. He went with the TZXDuino Reloaded, so i was leaning that way myself. I was going to go the PCBWAY/JLPCB route with the gerber files and maybe make some customisations to the look(but not design).

    Yeah my plan was to put one together myself too, but, in typical fashion, no single retailer of components has everything you need. From a preliminary look this morning, I counted at least x3 retailers that I'd have to buy from...of course all with their own handling charges and delivery charges.

    For what should be a cheap and simple tape deck emulator, this has pushed the price to bananas levels. Currently looking at the Maxduino Ultimate here, but as a complete product. Really not sure what direction to take.
