But is that worth $170? Especially when I don't have noise issues with my stock SONY PSUs or my SEASONIC? In my opinion, it is not worth $170. Sure, it's nice to have a modern, well made power supply. But if you watch my SEASONIC video from 2018, I was able to get such a PSU and...

Even the lower cost PSU from TT shows the same 5V rail voltages, which is what I would expect... https://github.com/tt-design-studio/psu-mac-se I'm therefore not seeing the practical benefit of the $170 version over the $129 one.

Thank you for the detailed info! I assume you don't have any of those PSUs yet and are merely mulling which one to buy? As I thought, even the top end PSU costing $170 cannot get around resistivity losses due to it outputting close to 5V. That is shown by the voltage measurements presented in...

Thank you for your kindness, but you may not need to re-run it in v3.06. I just downloaded v3.23 and checked its version history, which indicates the only change impacting 040 processors (not the 030 like you and I are testing)... This also means none of us should use Speedometer versions...

I did not use Speedometer 3.23, unfortunately. When checking the Speedometer 3 page on Macintosh Garden, it says this: Note: Algorithm changes occurred at v3.01 and v3.1; so absolute benchmark results across those version boundaries are not strictly comparable. That implies that the 3.06...

@fehervaria Very odd I missed seeing your thread (started back in 2021) until today! Wow! So the interface shown in your opening post allows you to use ADC displays on modern computers via HDMI? Or does your adapter allow the vintage computer (like a G4 Cube) to connect to modern HDMI...

I have not. I have only reviewed the BabyFace PSU. I believe that TT Design version came out AFTER the BabyFace was released. Not sure who "borrowed" whose idea, but they both use the same "modular" voltage conversion units. And in my testing, I can tell you that you will get loss through...

So... We should the following? 1. Connect one end of a normal Mac serial cable to the vintage Mac. 2. Connect the other end to a serial-to-USB adapter, then connect the USB plug into the modern Mac. 3. Launch Basilisk II (System 7.1? 7.5.5?), then launch TinyTransfer from within Basilisk II...

And here are the MacBench 3.0 results, showing that CPU/FPU are essentially the same for your board and mine, but your board still shows a bit higher on the Graphics... Even so, if you consider how much lower the Graphics scores are with the 25MHz LC520 board, I don't think it can be said...

Hmmm... I just did the side-by-side with your Speedometer 4 benchmark results (shown at right below — I renamed your record), and my overclocked LC520 board at left. All numbers (except Disk) are clearly within "testing error" difference. So I guess this gives strong evidence that the BUS...

@kefkafloyd Thank you. I downloaded your file and opened the Speedometer folder and I see Records "3 & 4" but do you which specific version of each? As you can see below, I have my own 3.06 and 4.01 folders (top left). I believe the creator of Speedometer changed this testing methodology...

It's a 512K Mac with Kay Koba's Fat Mac Switcher and also his ROM-inator I. The short summaries of those 2 videos are: 1. Fat Mac Switcher: Allows selection of 512K or 128K RAM (while Mac is OFF). 2. ROM-inator I: Allows you to flash the stock 128K ROMs, 64K ROMs, or customized ROMs. I...

Wait... You were in bed preparing for slumber when you suddenly remembered your password was Golden Slumbers? :-) That's pretty amazing. But it also shows you put priority on a good nights' sleep. And with all that programming prowess you have, David, I can see why a solid 8-hours is...

Yes, I have the ROM-inator (128K ROMs) in my Fat Mac Switcher equipped Mac512, but how is EasyShare used?

Wonderful! Extracted from tape backup no less! Thank you for your preservation efforts, David!

@dougg3 , @Fizzbinn , and you other LC550 owners... Sorry for the trouble, but could you please post your LC550 board benchmarks in the following apps? Norton System Info 3.5.3 Norton System Info 3.2.1 Speedometer 4.0 Speedometer 3.0.6 MacBench 3.0 (all tests) It could be that no single one...

@Scorpio_ny Both look fantastic. Well done!

@Kai Robinson If I buy the LCD kit for my Color Classic, will you watch it in its entirety? :geek: Regardless, I am strangely compelled to open my low-on-cash wallet for this kit, even though I know I will likely get hate from the purists who demand CRT tubes in every vintage machine out there...

I don't know if I have "OCD" but I do get "hot and bothered" (he he) by specs of dust behind glass, and I experienced that a lot when doing my iMac graphics card bake videos.

You mentioned System 6 being associated with speed, which it absolutely is, but the 512K machines are made to use even older versions of System Software. System 3.2 & Finder 5.1 work rather well for the period-correct application software you would likely use on such machines. They are also...
