Dear Mr. Chadwick
I have 2 Apple PDQ 300 Mhz Wallstreets, and would like to build new PRAM batteries for them.
Do you know a source for those PCB's for the VL2330 batteries? I found the Keystone 534-3005 holders on Mouser.
I found them on Digikey, very expensive! Thank you for your time!

i made those PCBs myself... i made them in fritzing because it was fun and fast... nowadays, i would probably use EasyEDA or something.

i am NOT convinced the boards work correctly.

the wiring is correct, it's a really simple layout, but something about the board doesn't agree with the PowerBook. Maybe the board introduces too much resistance or something? I have not had time to go back and explore that project.

here is a folder with all the information, including the Fritzing file. Let me know what you make.

Finished building a small home studio for messing with making beats. Just a little hobby. Mac Mini M4 16gb RAM 512GB SSD, with a 2TB SSD in a Satechi M4 hub. Software is Reason 13+ with Behringer RD-8 and RD-9 drum machines, TD-3 baseline synth, Focusrite interface, and a Nektar Panorama T4 keyboard controller. The Mac Mini is sweet. Tiny footprint, and powerful. It can run most of my Steam games with no issue.

I got one of those just about a month-and-a-half ago (the machinery damage letter) - I only lost a couple of replacement floppy gears out of several that I ordered.
I was poking at 7.1.1 Pro out of curiosity, since one of my disk images had it for some reason. (I'm already sold on 7.1 with the System Update and everything, very aware of Pro's reputation and status.) However, I noticed that the startup time is abysmal, even on zero-wait Mac II-family emulators. Even After Dark screensavers seem to hitch a bit, indicating context switches to some kind of background process. What did they stuff the System File with? Is this the true power of PowerTalk?

QT, PC Exchange, AppleScript add some overhead, but it's mostly PowerTalk. Almost nothing new in the system files.

That's what I figured from looking more closely at the resources. I think TokenTalk is even included by default.

Sigh. I once had a PowerBook 100. Bought it for ≈£320 in spring/summer 1996. Loved it. I had an external FD for it. The 40MB HD did start to die after a few years, but I was able to repartition it as a 29MB drive.

@ClassicGuyPhilly -How about one of these??! I actually used one of these back in the day for my first online experience. AOL_20disk.jpg

But seriously, I miss the time when we had more choices for our internet providers.....even if the speed was limited to 9600 (14400 by the time I got online). Now it is mostly a crappy monopoly......

Anyways, I like the fact that you have the total package from Prodigy...right down to the dial-up number guide! It's a cool time capsule.

@JT737 haha thanks! I actually worked for a regional ISP 96-98, we always had a lot of user churn with people switching between providers. Love the AOL disk!

@ClassicGuyPhilly -Did you ever hear of a local ISP called "Galaxy Internet Service"? I had them from about 2000 until 2013 when they, unfortunately, when out of business....pushed out by crappy and completely enshitified ISP's such as ComCa$t.

Preparing this guy to go out for a recap including taking two jumbo antistatic bags and combining into an uberantistaticbag!

Look at how much elbow room all those PLCCs have... That's one nice PCB layout.

@luRaichu The Plus/SE era machines with the big traces and pre-SMT designs are beautiful. Especially how all the traces are tinned and silvery looking in the SE, or at least on mine. That accelerator you routed makes me want a Plus, if I ever get the space for one.
Loving the Mac Prodigy 040/060 conversation thread. I have enough familiarity with the topic to follow along, but little to no practical experience beyond being a PC builder, Apple ][ software hacker, and just currently an end user and consumer.

As such, my Centris 650 and I would love to be a part of the process. If that means waiting until things are all done and commercially available, then so be it.
If a tech minded consumer beta tester has any value to the process, kindly put my name on that list.

Thanks - it looks like it's going to be a fun ride and a cool piece of hardware!

Thanks for the warm welcome, as soon as the card starts working on my LC475, I would be considering to give out cards to betatesters such as you. Thanks for the offer! :)
Thrilled to share my IIfx is finally fully operational and already being put to important use! ;)

My SE/30 logic board (my only LB not washed/recapped solely by me) is riddled with residual corrosion. I can smell it when reflowing. It's my fault for believing the person who sold it was a professional in the first place, but this was ~10 years ago, when I would've made all these same errors. Should I dare trying to lift every single SMT component with hot air? Go for a Reloaded PCB?

If that doesn't fix the voltage sag, it might need the PSU recapping if it hasn't been already.

I have the fancy aftermarket Meanwell PSU, I had no idea about the trimpots in the stock ones. This is for sure a LB issue, I found smelly gunk under multiple ICs. The last person likely didn't clean at all before recap. Since I can't guarantee the integrity of the inner layers or vias, I'm strongly leaning towards attempting a Reloaded PCB. I know it's normally uncalled for at this point, but I have the itch.

OK, but as long as the loaded voltage on the new PSU is above 4.95V on the 5v Rail, higher if possible.
