Thanks for that extra info, @joshc. I’m in the process of getting the parts ordered and will have a go using the resources (and parts numbers!) you have provided. The Seasonic PSU has already arrived. If I’m successful, I’ll try to post here as well.

Thanks for the reply! I’m good up until the point of the circuit, and then I’m a bit lost, as I have no electrical engineering experience. My ability sadly ends at recapping and soldering. Will have a friend look at it and tell me exactly what I need to do. For instance, I wish this made total...

If you ever have a moment, would it be possible to explain (or show) how to match up the wires between the Seasonic and the original adapter the plugs into the motherboard on the IIci/Q700? I’m still unsure how to do the matching. Thanks, and great work!

I think that’s right regarding the IIvx supply. Pretty sure it’s the same as the one that powers the Q700/IIcx/IIci, and a quick internet search appears to confirm that. I even swapped in a 7100 PSU into my Q700 when its PSU died. Prioritising the SE & SE30 + IIcx/ci/vx/Q700 designs seems...

Looking good! That’s a very clean design as well. Thanks for the regular updates. Can’t wait to see how this progresses.

Thanks for all of these replies. It truly is a bit perplexing. @dan.dem I don’t have RAM Doubler installed on this machine, but that was an interesting observation. @Byrd Weirdly enough, this is the only evidence of any kind of issue or corruption I’ve noticed in the usage of the computer...

I've been going through trying to determine the state of a few of my machines recently (all have recapped logic boards), and I've noticed a sporadic oddity when shutting down, and I don't know if it's related to a logic board issue, something to do with the aged HDD or even the PSU. If you look...

Not so much of a conquest as such, but my wife and I just moved into a new house, and it’s rare to see so much (but not all) of my collection together in one place.

PM sent for the preorder. Apologies for the very basic question, but if I need an external power brick to power an 80-watt picoPSU, can the power adapter have either a lower or higher wattage rating if the Mac LC is only drawing a fraction of the power available? The other problem is the voltage...

That’s a great find. Enjoy the IIx! It’s one of the prizes of my collection. When my wife threatens me with getting rid of my old Macs, I tell her she’ll have to pry the IIx, IIci and Quadra 700 out of my cold, dead hands (by that point, I guess my arms would be pretty full).

Oh nice one. I hadn’t realised that there were third party versions of these at the time. Thanks for sharing!

Do you have any pointers regarding some of the latter examples? I remember trying to image a copy of Warcraft II, as I only had the original disc and didn’t want to lose the data if it were to get lost or damaged. That disc was complicated, because it contained both separate audio partitions AND...

Thanks so much for doing this. I don’t even own an EtherMac, but have run into the driver issue for ethernet peripherals in the past. How incredible that you stumbled across these on eBay.

That’s really helpful. Thanks for the links. Yes, it’s strange that the black ones are selling for less than the grey ones, given that they’re essentially the same. Will pick up one of the offerings from the UK.

I’m really sorry for necro-ing this post, but I’m after one of these adapters so I can plug one of my hefty multiple-scan Apple monitors into the VGA port on my MDD G4 or my 8600’s Radeon 7000 (or even *gasp* to test on my gaming PC). Has anyone had any luck sourcing these recently? I found...

This issue has annoyingly reared its head again. I’m not getting any Ethernet connectivity in Mac OS 10.4.11 or 9.2.2. OS 9 just self-assigns an IP (169.xx) and OS X doesn’t show ethernet as being connected at all. Any thoughts on what the culprit could be? I’m guessing hardware at this stage...

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...

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...

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...

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...
