  1. Firstly, awesome project, the vintage Mac community is in some dire need of this sort of thing compared to the Amiga community which already has a lot of reproduction boards ready to buy. Secondly, that is possibly the most exploded PRAM battery I've ever seen - that looks scary to touch or even go near.

    Need soldering help, likely damaged board :(

    Same thing happened to me, I bought a desoldering station which just sucks all solder from the hole effortlessly. All other methods failed for me. Glad you got yours sorted using the needle trick.
  3. Very cool, impressed how you packed everything in there! Is any of what you installed compatible with OS 9?

    SE/30 with an expansion card

    More photos would be good, I know its sad to see but its always intruiging seeing the extent of battery corrosion damage. Got any photos of the RasterOps card yet?
  5. I've definitely got the 'ebay bug' so there's quite a few items in this listing, all bought separately...
  6. Thanks, I forgot about these - yes both planned. I need to find a spares/repairs MDD to raid the graphics card from. Funnily enough, this Mac only chimed once - when I first got it, every single boot since then hasn't produced a chime (even before I did the tear down). I'm not sure why this is yet. And yes the speaker is plugged in You might get a PM from me about this!

    Power Mac G4 with Sonnet upgrade

    Restoration thread started:
  8. Original thread for this machine in Conquests: This is the restoration thread for my Power Mac G4 with Sonnet 1.6 GHz upgrade that I recently acquired from eBay. The stock speed of this machine was 400MHz. It has been upgraded to 1.5 GB RAM by the previous owner. No hard drives are in the machine yet. When I received the machine, it was not in the best of condition (cosmetically), but most of this was just because it hadn't been cleaned for a long time by the looks of it. What I'm doing to begin with is cleaning, I don't like working on a dirty machine so this is my first priority, upgrades and further changes can come later. Typical dirt under the top cover, no idea how this happens but it seems to be a common problem. The front panel, not too bad: Inside, typical dirt Side panels have seen better days, but most of this is just light surface marks although some of the scratches are deep. The real reason I bought the machine, the Sonnet Encore GT upgrade: I did a power on test, and the machine boots from a Tiger disc OK - System profiler confirms the RAM / CPU specs I've mentioned above. I can't go further than that until I get some storage for the machine. So, onto the cleaning. I started at 11AM today and finished at 3.30PM, to completey disassemble and clean everything and then reassemble the machine. Top cover removed to clean that first... Afterwards: The state I received the bottom covers and handles in: I didn't want to spend ages scrubbing the handles, so I soaked them in hot water and detergent Someone wrote 'M' in permanent marker on the back...ugh Dirt, dirt everywhere Inside, things don't improve... OK, it was then time to remove the first side panel. The fan assembly has to be removed first. There are plastic clips behind the fan assembly which need to be pushed inwards to release the side panel. This was a little tricky but they eventually loosened up - and they didn't break! It's not surprising, but the vents don't have lots of room so dust gets stuck easily over time. Back of the side panel: Don't worry fan, you'll get some attention soon... With the back cover removed, the Mac starts to look more naked... Front panel removed from... the front: The chassis is very roomy when there's nothing in there... Drive caddys needed a good wipe down I made some progress with the permanent marker, but got bored of scrubbing, so this is where it's up to now... I took the cover off the PSU to inspect it. No surprises here, it looks pretty clean and there's no obvious sign of any imminent component failure. I gave it a quick clean, took the fan out to clean it, and put it back together. This won't be recapped for now as it seems fine. All the things were cleaned... The side panels were a little challenging, but I did make some improvement to them...Tooth paste worked the best for removing the stubborn scuff marks. Before: D During: After. I couldn't remove the blue marks - one to tackle another day. Getting closer now... I took apart the CPU fan assembly to clean it. This is a silly little fan which makes too much noise - I will work something out to improve this later. Ahhh, this is better... Things going back in: I'm pleased with it for now, pretty handsome... So, what's next for this machine? An 80GB IDE hard drive is meant to be arriving in the post next week, and I should have a compatible OS 9 install disc by then too (I found some original Power Mac G4 discs and a manual on eBay). Longer term plans... - A 2nd IDE drive? Dual boot OS 9 / OS X - SATA card / SATA SSD - Better fans - Recap logic board - Work out what to use it for, except for it looking very pretty under my desk Thanks for reading

    Mac SE/30 PDS & Power Questions

    @cheesestraws does some 68k programming so may be able to help, possibly. There was also the guy who wrote some 68k software so that he could add Wifi functionality to System 7? In terms of this matching the Micron Xceed functionality, will it also provide support for an external colour display? @maceffects Sign me up for the non-Linux version, I am primarily interested in getting the Micon Xceed functionality at a reasonable price.

    Power Mac G4 with Sonnet upgrade

    Managed to boot from a Tiger disc and open System Profiler, the Sonnet upgrade is a single 1.6 GHz CPU.
  11. I acquired a Power Mac G4 with Sonnet upgrade for a very good price from eBay. Asked the seller to remove the handles which they did and it arrived in one piece! The original speed was 400 MHz but with the Sonnet upgrade this will be higher now, I don't know the clock speed yet. I did a quick power on test with monitor plugged in, chimes and displays video fine. I don't have any system discs that will work with it yet, but that's the next thing to sort. The machine does not have any drives so I am just working out my options for putting an SSD in here. My plans for this machine are: Full disassembly / tear down Full clean of every part Inspect PSU, make a judgement on recapping Replace electrolytic capacitors on the logic board SSD conversion Add a spinning disk of some sort Find a Sonnet Tempo SATA card Install OS 9 / OS X Set up a file server Install some games Eventually find an internal Zip drive to add to it Enjoy it
  12. I found this, which confirms Canon sold the 128K in Japan, starting from April 1984: https://www.nytimes.com/1984/04/13/business/the-macintosh-in-japan-debut.html Apple worked with Canon a lot over the years, mostly on the printer side of their business.

    Awful Macintosh SE FDHD Revival

    Do you mean you just mix hot water and Vanish and nothing else? I have a tub of Vanish but found it hard to get peroxide cheap enough.
  14. That's a really nice G3 tower. My former 8200...ehh, all I can say is good luck

    LC475 / Power Macintosh 8200 / Performa 630

    I sold the 8200 to @Paulie who is going to try replacing the PSU to get it working again. The 475 still doesn't work, it needs further board-level diagnosis to seek out what's going on, it's beyond a PRAM-related issue in my opinion and currently a little beyond my skill level at this point but something worth investigating in the future as I would like a working 475 again. The 630 is alive and well and I managed to re-attach the front bezel, I would like to do a CF conversion with it but will need to find an adapter that works with its early/crippled implementation of IDE.
