Well, what I do in terms of using my MacSD, BlueSCSI or FloppyEMU is yank the SD card, then put it into an Intel Mac (because, very sadly, Apple Silicon Macs make it 100% impossible for me to avoid "fragmentation"), transfer files, then put the SD card back. It's fast and works well (except for...

In reply, I should mention that your opening post says this: So we need to define "older machines" and "retro computer." Specifically, what machines would become incompatible if you "add some JavaScript to make it feel more modern"? Once that is known, people would probably provide...

@Kay K.M.Mods & @Drake Those are some very cool icons!

I'm watching this thread with interest because I too a PDQ (Pretty Darned Quirky) and it has power-on issues too.

The upside is that I broke my tabs so other people don't have to! :-) Naturally, I didn't do it on purpose. I really was given bad advice. I don't see how some people contend that drop-to-open works on that MacEffects case. It didn't for me, obviously. But it does work fine on the stock...

@YMK said he didn't experience noise, and he did the component swap. However, it does not seem that the legs on his replacement components were very long... https://tinkerdifferent.com/threads/color-classic-analog-board-trouble.2367/#post-21638 So I am wondering if the raising up of larger...

My first Apple II was acquired in October 2023. Being a Mac guy since 1984, I was accustomed to "good audio." There was nothing about any Macintosh I ever used that made me think, "Wow, this audio is bad!" But when I first tested the IIc with music and gaming apps, I was really quite shocked...

IIci schematic sent to you via PM just now. Here are SE/30 Schematics. Here are Macintosh Portable Schematics (5120)

Yes... https://tinkerdifferent.com/resources/macintosh-portable-5120-schematic.133/

"Messed with the metal shielding" how, specifically? The fact that "messing" changed something is a bit concerning.

Wow! A great way to end 2024. Always love to see ongoing development of an existing product in the vintage computing space. It really keeps the fun alive and enhances product usefulness too! Best wishes to all of you as we ring in the New Year very shortly!

@YMK I'm rather embarrassed to say that even though I bought all the components for the swap, I've actually still not made time to do it yet! That's something I plan to do a video on, but it's not done yet. However, since you have done the component swap, did you experience any noise increase...

It was the same when my Micron Xceed card had VRAM related issues. Switching between color and grayscale or switching between number of colors would sometimes resolve the problem. But ultimately, replacing the defective VRAM chip was the solution. Congrats on the purchase of that excellent...

Will there be a part II video where you show us the same desktop windows again to see if the problem you showed at the beginning of your video vanishes with that different video card? Before you even mentioned having discussed it on Discord, I too thought it might be the video card —...

Cost is a valid consideration, and bulk buys would be nice if they generated discounts, but I must say this. I've tested v2 with a wide range of Macs, and even on a slow, stock 8MHz Mac SE, benchmark apps across the board show the v2 to be faster. Noticeably? Well, that would depend on you. I...

Oh, that photo was of a IIfx? I don't have a IIfx either. But what I wrote about tantalum capacitors still is correct info. If that C1 is across a 12V rail, it explains the burn.

I do not own a IIsi, but it would be interesting to know more info about C1, such as: 1. What is its capacitance and VOLTAGE RATING. 2. Does C1 see +12V across it at any time? (Is it on the 5v or 12v rail?) I've seen so many bad designs, even from Apple, using under-rated SOLID tantalum...

I assume that 5.4v you measured from the power supply was with the PSU disconnected and in the no-load state, correct? If so, what is your loaded state? Do you measure something more along the lines of 5.0v when the power supply is driving the motherboard and with the computer on? Because if...

@wottle Did you get all the bits of tiny dirty particles out prior to deyellowing? May need to use 409 or 100% IPA (something strong, but not brutal) to get the teensy tiny grime out, as that can cause lackluster deyellowing results. You may need to use the rough side of a dish washing sponge...

I too have a Daystar PowerCache accelerator in my SE/30, but mine is the CPU-socketed type which requires a socketed 68030 CPU type motherboard, but NO ADAPTER. That type of PowerCache looks like this: (Photos taken back in 2013, so ignore the motherboard caps and PRAM battery. MB has been...
