Folks, I'm in the middle of filming the STEREO MOD, and I want to mention a few things... FIRST, I wish to thank @Jagmn once again because he posted a second speaker CASE design that doesn't have the tab on the back, which can be helpful when mounting two speakers inside the Color Classic...

I must be completely honest with you in that I simply do not have time to spend on fun projects like that. Perhaps if I quite YouTube entirely, I might. But I'd rather make videos instead. :-)

@pocketscience Speedometer 3.x and 4.x are different, so you would need to specify the version used. Doing Norton 3.5.x Speed Info is another good benchmark to run. I also recommend running MacBench 3.0 (all tests), as that will run on an SE/30 just fine, whereas version 4.0 will not. The...

I'm curious as well. I have the DiiMO (which you kindly repaired for me -- thank you!) and the socketed PowerCache. In every benchmark test I've tried, the DiiMO is just a tad bit faster than the PowerCache, even though both have '030 processors running at 50MHz. I believe the reason is due...

The BMOW ROM-inator II works fine with the PowerCache board, but Garrett's Workship ROM doesn't work with it. The last I spoke to Zane, he suspected it could be a timing issue. But if you don't have a PowerCache, then all is well with Zane's ROM. I did a lot of testing.

If you are taking about the Daystar Turbo040, then yes, you need only have the ARTMIX TS Adapter like I have, or get one of Bolle's creations which are even better due to added functionality. I don't have a comprehensive accelerator card compatibility list though because I am not the creator of...

Most likely an older edition. These are photos of my 40MHz Turbo040, prior to the ASIC repair... And here's a version of the Turbo040 shown in the Daystar documentation...

Glad you enjoyed the read. It certainly was a learning experience! Even with the right chips, it took some excellent troubleshooting and soldering on the part of Bolle to get it fixed. So in the end it was the dynamic duo of @joethezombie and @Bolle who resurrected the Daystar Turbo040. I am...

That would be perfect, yes!

It's not hard to make them, as I show from the 35:49 timestamp in my video. Amazon links to the cable and heat shrink tubing are found within the text description under the video on Youtube.

It really is an amazing story if you took time to mostly read through that entire thread. The unbelievable part is that @joethezombie was able to buy a batch of new, old stock Daystar ASIC chips, without which the repair would have been impossible. Simply incredible!

For the sake of clarity, it is important to note that the TDA7052A (click for data sheet) is a dedicated audio amplifier IC, whereas the LM3080N is a special kind of op-amp called an Operational Transconductance Amplifier, which is used as a voltage-controlled current source. So if indeed, the...

Here is why plugging a cache card into a PDS slot is a bad idea… The entire story is in my old thread… https://68kmla.org/bb/index.php?threads/se-30-pds-adapter-epic-blunder.32138/

@retr01 was the one who first brought it to my attention. I had not seen it before. And just to be clear (for those who don't like to read the entire Google translation of the product page, this is a PDS splitter. You get 2 PDS slots instead of one. The TS Adapter and the TS Adapter clone...

Here are more stats from just now, as pertaining to the Speedy Bends video... Lost 1 subscriber. Lower than normal performance and view time. Lower number of views than normal. I kind of expected that, but I still wanted to try to do some shorter videos just to prove to the younger...

Here's the rough Google Translation of that web page (except graphics, of course): https://www-marushin--web-com.translate.goog/org_dualpds.html?_x_tr_sch=http&_x_tr_sl=ja&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=sc Kay Koba has long told me that the market for vintage Mac stuff is quite large...

Glad to hear the transistor swap worked. Testing an NPN BJT transistor with a resistor on the "base" is important to protect the transistor from damage. Without a base resistor, the transistor can be damaged. That is not true of a MOSTFET though, since those are voltage controlled. BJT...

I just finished watching. Very nice video. I wrote a comment under the video to explain that the LC575 board is very sensitive when it comes to overclocking. I'm curious if he tried stably overclocking beyond 45MHz (a) with the PPC card completely removed, or (b) with a different 040 CPU. I...

Thank you very much! Here are the latest YouTube Stats... "Your estimated revenue" doesn't exist because I don't allow Ads on my videos. Even at 5K subscribers, Ads wouldn't bring me anything but a few measly dollars per month, and that tiny sum wouldn't be worth my time needed to report...

You know you're getting successful on YouTube when foreign language SPAM hits seconds or minutes after a video debut... You'd think that they'd use German names instead of Vladimir and Martinez. Anyway, as you can see, I like to have fun with the spammers before I delete them.
