This is a very charitable use of the term "run" 😄 Btw the PM6100 G3 accelerator is a pretty cool design, it's narrow enough that it slots vertically into the PDS and looks like it has a passthrough for eg an HPV card, so I am trying to get a hold of one to see if it makes a difference.

Yes I should have specified - I took the G3 accelerator card out so those last numbers are just off the 601@66 with and without 256kB L2 cache (which I also physically removed for testing) Cache: 601 seems to be around +10% for this with 256kB L2 G3: about 4x as fast, phew! (G3 has its own...

Disabled the card and updated the post! I also discovered that my PSU fan is busted so it's really cooking in there now 😱

I think I posted this in the other thread but I hadn't actually carried it out at that point - I connected mine like this and it works great! I removed the connectors on the Mean Well, stripped the ends of the wires from the connector I took from the LC PSU, and taped both the Mean Well AND the...

That's the thing, though - they don't FEEL slow (at least with System 7.1) - unless you're doing something crazy like opening a jpeg 😆

I'd suggest 32MB - this gets you 36MB with the soldered 4MB, plenty for a 68k machine, very reasonable boot times, and no potential issues closing the lid 😄 (some of those higher capacity RAM chips are longer and can get in the way of getting the lid on)

Congratulations on your machine! The LC475 is fantastic 😄 great form factor to work on, and thanks to some R&D by members of this forum you can overclock it in software: https://68kmla.org/bb/index.php?threads/overclock-lc475-p475-q605-without-soldering-or-spicy-o-clock.47946/

You are legally entitled to keep the card and not worry about this anymore! But if we look past the back and forth and sob stories: You wanted this card, and were willing to pay for it (and did so). Even though the seller is clearly out to lunch, they did actually provide you with something of...

For me it's safety and availability: - a button cell won't cause the same catastrophic damage if it leaks - I can buy button cells at the grocery store, getting the 1/2AA size is a huge pain in the ass by comparison

Great find! That era was super interesting - first generation PPC, still has NuBus, before the switchover to IDE so still rockin' SCSI. Also wow I didn't know the 7100 had that many caps, that's quite a project when you decide to recap 😅

Couldn't resist and had a quick poke at the CPU - cleared off the solder blobs and pushed the legs back (chisel tip ftw), the CPU and a couple of the other chips get hot when I power it up but still no other life signs unfortunately! Will investigate more on monday 😆

Oooh thank you - yes this definitely looks suspicious 🧐 This is a big help!

Nice! Thank you so much - looks like a busy monday for me 😅 Will definitely also check the caps, I am particularly embarassed about C115 😱

and finally, detailed shot of the battery area

Hi everybody! I have a 5400/160 that I pulled from a machine which I'd like to get up and running, but I'm stuck. - The machine did not bong or output video when I fired it up - I've also tested it in a known good 6200 (where it currently resides), still no bong or video. The speaker pops but I...

Congratulations! Where in the world are you located? And what kind of compromises are you willing to make? - eg Quadra 610 instead of Centris (esp. if you are swapping in a full fat 040) - do you need the CD bezel or the blank bezel for the central slot - requirements for feet situation...

This is absolutely phenomenal work, and puts mine to shame 😄 well done, this is incredible!

I think I've only ever seen the "sticker" version - consistent with how the "big pizza" Q610 cases were done
