Am I a tech relic because I have a BD-ROM drive in my pc and I have a USB BD burner? It even has the 2-headed cable for extra power. You never know when you might need to burn a disc. Also, I bought a USB floppy drive and some disks because the high schoolers at work didn't know what the save icon was.

I met him at the Vintage Computer Festival Midwest in 2019, and I am pretty sure that was under Chicago's extremely strict gun laws even. Wow! No wonder he was constantly in a state of panic and brandishing knives at everyone who approached

Family photos burned to three or four and stored in a fire safe alongside a portable hard drive. Also 200 or so discs archiving various media and poo poo. When you're a data hoarder who can't afford a big-rear end NAS, this is the next best thing.

Or you can do it manually, by removing them and rebooting, and do the elimination process that way.

It could also be a damaged filesystem or a bad harddrive, but the logic board is most likely fine. Make sure to replace the battery and solder in new capacitors if you want to make it stay working in the long term though.

Apropos nothing in particular, I wish 3com were still around. I have nothing particular against intel ethernet cards (except the wild markup on 8 year old designs if you try to buy one in Norway), but having two real alternatives for decent NICs would be nice.

r u ready to WALK posted:It could also be a damaged filesystem or a bad harddrive, but the logic board is most likely fine. When I got there, we turned it on and it got to that same screen again... so I turned it off and restarted with the shift key held down. It immediately displayed the same screen as before, but with some video artifacts. The picture continued to degrade over a few cycles until it settled into the "simasimac" pattern. I made them a low offer, they took it, I now have the Mac. The case is super clean and un-yellowed, same for the keyboard and Kingston trackball, so even if I can't revive it, everything except the logic board is in great condition. After opening it up at home, I see that the capacitors have leaked a bit, but things aren't too nasty. The battery is marked 1989, but amazingly hadn't leaked at all. I've got a new set of capacitors and a CR2032 holder en route now.

Got the PowerBook G4 battery cell replaced with a DIY spot welder setup, ended up with a few old but unused Samsung cells at around 2 Ah. Lower capacity than the original but should be workable. Also got the mSATA drive and adapter, that part seem to work really well! KingSpec mSATA 128 GB + generic white IDE adapter board confirmed compatible. PRAM battery is completely dead; tried to order some LIR3032 rechargeable Li-Ion batteries but might take a while. Might temporarily install a protected Li-Po cell. New problem: The battery now reports charge at 100% (started at 97% then went up during the Leopard install process). However, as soon as I pull out the AC adapter it dies. On battery only it will not give any signs of life aside from a tiny barely audible chirp when I press the power button. Starting to wonder if there is a fault in the battery management PCB in the battery pack - it seems like it does output some voltage, but when loaded it immediately drops out.

I'd be interested in your spot welder setup, your source of replacement cells, and your overall process for doing this, since my G4 Powerbook battery cells are pretty hosed (I opened it up, 2/3 of the cells have weird discoloring on the outside and nothing has a charge worth a drat)

It's a bit marginal wrt. energy so I did 3 shots per weld and it seemed to give pretty good results. There are a lot of options you can get off eBay that use a lead acid battery or similar as a power source, I bought this one https://www.ebay.com/itm/184525077044 and used the probes it came with for my own welder, but haven't actually powered that one up. Impression of it was fairly good, it actually came with two full pages of useful instructions on how to do the welding properly. Not the safest thing in the world (wear safety glasses for flying sparks), but it does work. I practiced by welding some nickel-steel strips together, then onto some dead AA cells before trying the Li-Ion batteries. As for replacement cells I have a local supplier that sells what is almost certainly legitimate new cells from e.g. Panasonic/Samsung. They don't like selling unprotected cells for obvious reasons, but they will do. There are a lot of counterfeit 18650s out there that sort of work but have terrible capacity or current capacity, buying cheap batteries off eBay is a great way to find them. Basically every laptop battery ever made uses unprotected 18650 cells, typically 6 or 8 cells in total depending on if it's a 12 or 14 V battery. Obviously unprotected cells are also relatively dangerous, do not short circuit them or you may discover how difficult a lithium fueled fire is to put out. If I were buying new cells I'd probably go for Panasonic NCR18650(B)s, since I already use those for my flashlights (that model is really good at low temperatures!). If this works out I might rebuild it with those, but I'm not in a hurry to buy ~$70 worth of batteries just to find out something else is broken. Humbug Scoolbus posted:I have a PB Duo with a pack with dead NIMH cells in it. Any of you know how I would go about rebuilding it? You might be able to get new Ni-Mh cells with battery tabs already welded on, in that case you could possibly solder in new batteries instead of welding. Disassembly varies between hard and impossible depending on the design; the 2005 PB battery is relatively easy to get into with a scalpel, while others are effectively completely potted in heavy silicone glue. And there may be some battery charge controller fuckery to reset it; for Open Firmware I think the "reset-all" command resets the battery controller too.

Battery rebuild's a no go for now, spent way too much time loving around and not enough finding out. For future reference, the 2005 PB battery uses a TI bq29312 analog front end and a bq20z80 processor. This is not a trivial device to reset, though someone with a good battery might be able to dump the configuration. Mine got stuck in a hard fault state where it blows the output fuse to protect the battery - though this was not blown when I initially put the batteries in and tested it. The fuse is a Sony SC series specialty device designed for this sort of thing. Bypassing protection to always output battery power does not allow it to start up. Though if you power on the computer, and then apply 12 V directly to the battery terminals it will keep running when the AC adapter is disconnected. PRAM battery Li-Po replacement seemed to work out though, will still swap in the coin-cell battery when I get it but it's a usable replacement. It still asks for a Wi-Fi password on every boot, but at least the clock keeps running when it's off now.

I redid a battery pack about ten years ago for my old 280 Duo using off-the-shelf NimH batteries that had tabs already spot welded on - I soldered the tabs together - but it was very difficult to get the cells tight enough together to put the pack back together and fit into the Duo. I managed it, sorta, but if I do it again, I’ll spotweld the tabs myself. The pack worked fine though. Iirc, I hacksawed the pack apart on the seams.

I got my SE/30 up and running after a recap! The hard drive seems to be kind of intermittent; I've verified that the cables are plugged in properly, but it gets the question-mark disk at startup at least 50% of the time. I'm currently leaning toward a SCSI2SD v5.5 so I can just plug it into the external SCSI port, since the SE/30 doesn't have a second front drive slot like the plain SE. Anyone have recommendations about SCSI to SD adapters, experience with the v5.5, etc? Edit: I guess there's no reason I couldn't get the internal one, install it, and just leave the SD card in there, but it seems like it would be nice to have a library of hard disk images on SD cards that I could swap around. Also, I picked up a second SE/30 yesterday which will hopefully also revive after a recap, so the ease of switching an external SCSI2SD from one to the other would be cool Pham Nuwen has a new favorite as of 17:37 on Aug 14, 2021 |

Do you have a 3d printer or know someone that has one? If you can get an old scsi2sd v5 there's a nice bracket for it that uses the opening in the back of the SE for the sd card https://www.thingiverse.com/thing:2540695 It looks like the old v5 models cost more than the newer 5.5, if you have many machines it is definitely convenient to have an external one you can quickly move around. Although I think the coolest thing to get nowadays is the RaSCSI that uses a raspberry pi as the controller. This gives you a lot of flexibility like transferring files to it over wifi and emulating ethernet over scsi to get the machine online without expensive expansion cards. https://www.youtube.com/watch?v=Pat42MNRhhA

If you want to run a SD card out to the back of the computer there are FFC extenders for SD/µSD cards. I haven't tried one with a scsi2sd but that series of devices uses a fairly slow SD card data rate so a bit of cabling should be ok. The newer ones store the disk configuration on the SD card instead of the on-board flash, that seems like it would be much more convenient for swapping cards out. I think they also have USB SD-card access, though pretty slow. The RaSCSI is great, I put one in a case with a SCSI2 connector and the optional tiny OLED display, I use it for additional storage and on-line disk mirroring of the scsi2sd disks with Highware Personal Backup. It's slightly faster in some use cases, but in my benchmarking also slightly slower than the scsi2sd v5 in other use cases. A SE/30 is probably going to be equally fast with both solution. Downsides to using it as a primary drive: if you integrate it in the computer it will be significantly slower to boot since the Pi has to boot first. It also uses a huge amount of power compared to a scsi2sd - thermals are a real issue for closed fanless cases with a Pi + the RaSCSI board, to the point where I fabricated some copper conduction cooling brackets for mine. The Pi can also be used for things like web-proxies and file sharing, so if you don't already have that set up somewhere else it makes more sense as a primary emulator. One weird trick if you go that route: put the images folder on a separate partition and use btrfs with forced compression. Disk images are fully allocated by the emulator, but if you use compression it will compress empty disk images down to nothing. A typical system drive image is fairly compressible even when there's data in it, and the overhead is irrelevant on a Pi 4 at least.

Thanks for the pointer to the RaSCSI, I figured it ought to be possible to use a Pi as a drive, but since it's sold out on Tindie I think I'll order a SCSI2SD now and maybe get a RaSCSI later. Also planning to get the BMOW Mac ROM-inator II and a floppy emu. I got one machine for $100 and the other for $75, so I've not spent much considering what SE/30s go for these days, and I might as well outfit them properly.
