    Color Classic C4 and C5

    I’m going to expose my amateurishness here, but one thing I’ve done in the past is scrape away a little of the mask covering the trace immediately adjacent to the pad (near the point the pad disconnected from the trace) and then solder a jumper to that. Or, if the distance to the cap isn’t great, just solder straight over from the exposed trace to the cap. So, you may not necessarily need to route a jumper wire all that far at all. Again, others probably have more sensible suggestions.
  2. In 2009/10, I bought this 1st gen iBook for just £10. The replacement battery cost me 3x the price of the computer and I’ve long since discarded that (a side project may involve buying a replacement - likely dead - battery and rebuilding it, but I digress). Anyway, at the time, I’d noticed the beginnings of the dreaded tension cracks around the Apple logo. Over the last few years, it worsened and then seems to have stopped at its current state. Is there any way to lessen the strain on this area? Perhaps if I loosen the torx screws a bit on either side of the LCD? I suppose a permanent ‘solution’ would be to replace the bezel with one from a newer model, but then it may just look a bit off having, say, frosted white from an indigo model. Anyone else had this issue?
  3. Well, after all that - including adding a bit more solder to the connecting pins of the RJ45 port - I'm happy to report that Ethernet is seemingly back in action! I'm just glad it wasn't anything to do with the logic board. Thanks again for suggesting disassembly and testing with the multimeter. In doing that, I was able to at least rule out that specific hardware fault.
  4. I disassembled the Pismo to get at the RJ45 port. Ran a continuity test using a multimeter and didn’t discover any problem areas. There was clear indication of current across/between the 8 connections. I unfortunately can’t test the two capacitors, as my multimeter is pretty basic. So, in the end, I don’t think it’s the actual RJ45 port or a loose solder job (I may top it up anyway). I’ve pulled the pins up a bit as well just to ensure a good connection with the cable. I doubt reassembly will fix the problem, but I’ll get to that stage and think things through. Any more thoughts would be welcome!
  5. Thanks for the response. Yes, I'm increasingly thinking it's hardware related. There isn't any discernible activity on the ethernet router. I've just completed an installation of OS 10.4 (my OS 9 installation was fresh as well) and 'Ethernet' doesn't even appear in the available connections within 'Network' preferences. I'm not really looking forward to dismantling this thing and, even if I replace the RJ45 connector, I may not have solved the problem! Anyway, we'll see how things go.
  6. I recently picked up a Pismo (400MHz, 512MB RAM) and I'm having issues getting it to connect to my network via Ethernet. On both OS 9 and X, TCP/IP reports a 169.x self-assigned address rather than the 192.168.x I would expect. Running a browser or engaging Network Time does not kick the connection into gear. Manually entering an IP address and related information matching my network was unsuccessful. I've tested the same setup with a nearly identical Lombard (400MHz, 128MB RAM), and everything works well (as it does for all my other new and old machines). So, I've ruled out my network itself (despite having reset both my DSL modem and wireless router to see if that would help). However, I'm uncertain if there's a problem with the Ethernet port/card in the Pismo itself. Apple System Profile reports that the built-in Ethernet 'link' is 'down'. I've run an extended Apple Hardware Test, and it's not reporting any logic board issues (see photos). I'm running out of ideas about how to troubleshoot this problem and any help would be appreciated. Please see the included photos for more information. Thanks!

    haplain's never-ending quest

    Oh, that’s a really good point. A Rasp Pi could potentially be really useful in this scenario, but yeah, the drivers may be a limitation. I’d be interested to hear if you ever go down this route.

    Fitting a SCSI2SD in a 68k Mac

    I have an early version SCSI2SD sitting in an LCIII virtually unused. I’m also contemplating version 5.1 or 6. For some reason, I’ve JUST come across the now obvious idea of using SCSI2SD as an external device after seeing this listing on eBay. Having one device where I could swap in different SD cards based on the machine I was using at the time would be excellent. Does anyone have any advice about ‘official’ implementations of an external SCSI2SD setup or some good DIY guidelines to convert an internal SCSI2SD to include the external connector? Additionally, if I want to be able to use this external ‘drive’ between Macs from the IIx and SE/30 all the way through to, say, the LC475 and 7100, which version of SCSI2SD should I use - 5.1 or 6? I like the bells and whistles of v6 and the idea that it may receive longer support, but perhaps compatibility is an issue? The CODESRC site seems to suggest that v6 is compatible with the LC475 and Mac Classic, but I don’t know if that extends as far back as the IIx. Thanks!

    SSD for Powermac G3 beige minitower

    Interesting. I’ve always just opted for lower capacity CF cards for system files and most applications. 32GB is plenty of room for a lot of OS 9 apps and files. If necessary, I can then expand to external drives where necessary on ‘newer’ Macs like the MDD. Your first point about the possible wearing of CF cards due to excessive read/write cycles is definitely something I’ve wondered about. I use CF cards in my G3 laptops, G4 MDD and, if I’m remembering correctly, one of my desktops. Maybe the Performa 630 or was it the G3 desktop (can’t remember if the latter is IDE). Anyway, turning off VM is a good shout. I’ve always left it on, but it’s potentially doing more harm than good. I think one of my laptops - possibly the G3 iBook is running off an SD card, actually. It was a bit more fiddly to set up and get recognised by Drive Setup or whatever it’s called. That’s probably because it was a cheap converter bought off eBay, though. On a side note, and unrelated to the OP’s question, I do wish there was a cheaper alternative to SCSI2SD for SCSI Macs. I relied heavily on Max1zzz’s terminated SCA converters and older server drives, but one or two of those are not playing nice at the moment. A relatively inexpensive SCSI2SATA would be most welcome!

    SSD for Powermac G3 beige minitower

    I had gone the IDE-CF route for a lot of my IDE-based machines. Any opinions on why this might ultimately have been a mistake? I’m contemplating moving the IDE-mSATA route at some stage...

    LC 475 Chip Corrosion: When Standard Methods Fail

    I had never heard of an ultrasonic cleaner until now. Interesting suggestion. Doubt I’ll drop the cash on that for this one task, but it might be worth having one for the future. Yeah. I’ve not had any negative experiences with light applications of acetone. That said, it’s typically been ineffective at tackling heavier oxidation/corrosion. I’ve just read that a hydrochloric acid-based cleaning solution (e.g. toilet cleaner) when, applied in short bursts and quickly rinsed, can be quite effective. Might give that a whirl.
  12. I can’t remember the issue with this board - it may function fine, actually. It’s been fully recapped and cleaned. However, there’s quite a lot of corrosion at the base of the TI chip shown in the centre of the photo. It looks like the corrosion may even be bridging a couple leads. I’ve tried the typical techniques of removing it: 1) scrubbing 99% isopropyl alcohol with a toothbrush; 2) targeted scrubbing with acetone. The whole board has been through the dishwasher as well. I’ve read that baking soda might work, but I’ve not yet tried it. Does anyone have any suggestions how I can tackle this? Thanks!

    Finally, a Mac Mini!

    This was the first I’d read about this and I’ve had the very issue you describe with my G4 1.25GHz Mini. On one 1080p monitor, it works fine, but when set to 1080p plugged into my 4K monitor, there’s no image. I have to VNC in, remotely change the settings to something (anything) lower than 1080p and then I’m back in business. Thanks for explaining this issue and ending my frustration at the mystery.

    LazarusNine's Acquisitions

    It’s probably nothing special to many, but I finally bit the bullet and snagged a Pismo PowerBook off eBay. The seller misidentified it as a Lombard (which I already own). Given that my Lombard is a bit of a Frankensteined machine - had to replace the innards of a 333Mhz with 400MHz components - I’ve been looking for a replacement. The Pismo has always been a bit of a ‘holy grail’ (though by no means rare) which I’ve understood to a point, but beyond FireWire (which is a little useless these days), there’s not a vast difference between the 400MHz Lombard and Pismo. Perhaps that increased bus and larger RAM cap is something. Still, I’m pleased to finally have one of these on its way.
  15. I’d watch that! This is the device I use to capture from my old Macs, though I picked it up significantly cheaper on Amazon: https://www.startech.com/uk/AV/Converters/Video/usb-3-capture-device-vga~USB32VGCAPRO. This is an awesome project, by the way, and I’ve been following it steadily. Thanks for putting in the effort.
