@zigzagjoe I found your 68kMLA post where you mention "Speedometer 4.01" and then link to this page on Macintosh Garden, but that page only offers 4.0 and 4.02. So I will assume you meant to say "4.02" and use that in my testing. Anyway, I did find Speedometer 4.01 on one of my old hard...

@zigzagjoe Thank you for another detailed and extremely helpful reply! Your mention of using Speedometer 4.01 and Norton System Info 3.2.1 will allow me to use those two versions with my PDS-edition DiiMO and Synchr030 setup (and later my CPU-socketed PowerCache), so I can make better sense of...

"System bus" via CPU data transfers, you mean? I ask that question because in terms of the opening post's CPU score of 9.83 (in Speedometer 3.??) and my DiiMO's score of 10.42 (in Speedometer 3.23), I am curious if my DiiMO being faster than the Booster boils down to my use of Synchr030, or...

Thank you very much for your kindness in confirming that not only do Tetris and PoP sound great, but that Sound Manager is no longer an issue on the v2 Booster! I am aware of the 180Ω pull-up resistor mod (for the Booster) that is necessary to put your Booster card on top of the Synchr030. Wow...

@Ubik I read in that 68kMLA thread there were audio issues that pertained to the 1st edition Boosters like yours. Would you mind testing the following 2 games to see if the stock SE/30 audio (without Booster installed) sounds the same or different than with the Booster installed? 1. Spectrum...

Unfortunately, I don't have a schematic of the VRM to know which pins are what. Knowing that is very important if one wishes to test the VRM outside the Cube. But you're right, it does make good sense to test it outside the Cube if you are able to find out how to properly identify the voltage...

I talk about that from 53:14 in my video below, which pertains to the SE and SE/30...

Believe me, I've spoken to Steve Chamberlin about this via email and in the comments section of the FloppyEMU page for many months. Even though "it has nothing to do with Intel vs. Apple" in theory, I can tell you from PRACTICAL EXPERIENCE that it actually does have very much to do with an...

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...
