I've played with the Farallon version of this. Faster than LocalTalk, slower than Ethertalk, AppleTalk using the same serial port as LocalTalk. Without the special Farallon drivers the device still works but at normal Local Talk speeds. As BlueSCSI v2 with Pico-W allows you to emulate a...

I think its doable but if you don't have another use for the PDS slot not sure it would make sense considering you have a working Ethernet solution. But of course there is alway, "because it would be fun/cool for me to do" reason! This is a bookmark I had that you may have already seen...

I do but it has a Quadra 610 logic board in it! I couldn't get the original one (C 610 w/Ethernet) working. I did know there is a work around to take those boards to 25Mhz with working Ethernet just thought I'd bring it up in case it would be an issue and wasn't their radar :) ... I see the...

Does your Centris 610 board have built-in Ethernet? If so I seem to recall there are issues with this type of clock upgrade due to the oscillator being shared between the CPU and Ethernet (for its 10MHz clock)

Maybe its a 128MB module designed for the original PowerBook G3, pretty sure not all modules work the same between that machine and the PowerBook 3400 (its immediate predecessor) that otherwise use mechanically identical/compatible modules. You can look at the hardware dev notes for both...

I wonder if the original CD these Dev notes came from included info on what you needed to view them? Thanks, enjoying a first read of the LC one. I'm such nerd for these docs I feel like I'm studying the Dead Sea Scrolls. So far my favorite new (to me) insights: Page 18 - VRAM Options: No...

Amazing work. …really just awesome!

Wow! Awesome work @jmacz !

Woo-hoo! If it works it works!

I love the Original 15" Studio Display, especially the color scheme! In some alternate universe we'd have translucent black and dark blue 2nd generation Power Macintosh G3s. ("Black & Blue G3" instead of "Blue & White G3") In mine the pneumatic cylinder that is supposed let you adjust the...

Yep!

I have two dead 5xx power supplies in good physical condition, one even cracked open (hand squeeze pressure) with basically no damage. However when I got another PB 540 its power supply had a case basically destroyed on one end. I didn't feel too bad cannibalizing it to make the above. I don't...

Here's what mine looks like: I don't have a working battery so don't know if it would run and charge at the same time but it works just fine with vbatt and vmain tied together and no battery installed...

Crazy question... the vbatt and vmain are looking to be able to draw 2A at 16v. If *someone* were to use a modern 4.5A 16v power supply why couldn't you just tie vbatt and vmain in together to the modern power supply?

No problem. Sure, my goal in creating/posting stuff like this is to hopefully be of help to others, so increased visibility sounds good to me.

That’s my thread, feel free to use any of my pictures if they would be helpful.

So... funny thing is I never got to actually replacing the caps 😬 In buying parts machines to fix up my 5xx PBs I ended up with a power supply with a mostly destroyed case. I ended up grafting its cord onto an adapter box for a new/modern 16v power supply I got off amazon.
