Zane, I've never used that Audacity feature before, but I am now trying to understand it via the following process... 1. Launch Audacity. 2. New document. 3. Generate > Tone... 4. Sine / 100Hz / 0.8 / 30s / OK 5. Select All 6. Copy 7. Tracks > Add New > Mono Track 8. Paste 9. Analyze > Plot...

Zane, here are the 16-bit 48kHz audio files for you (Mono). WinterGames "Opening Ceremony" audio. (SE volume set to 3, D-100 recording level set to 5.5.) SpeedCard Enabled (bad sound) SpeedCard Disabled (good sound) (Right-click the ">>" and choose Download Audio from the popup menu. You...

I don't own that Carrera040, so I cannot say for sure. I sent Kay a message, asking him to reply to your question here. I can only say my SE/30 doesn't have any sound issues with the Daystar Turbo040, or socketed Daystar PowerCache, or PDS DiiMO accelerator cards. Apparently, only the...

Per your request, I will attempt to record a 48kHz, 16-bit WAV or AIFF (LCPM) file for you tonight or tomorrow using my D-100 recorder. If you are ultimately able to solve the distorted sound problem, it really would be magical. @Kay K.M.Mods has told me many times about his Carrera040 card...

I will try to make time to do that either tonight or tomorrow. I have a Sony D-100 Audio Recorder with a line level 1/8" input jack. It might work with the headphone output of the SE if I reduce the volume very low. I will experiment and see what happens. If the voltage level is low enough...

A very kind soul donated an entire SE motherboard with RAM and a SuperMac SpeedCard installed (16MHz 68000 with 68881 FPU!), and I had a chance to test it this evening. Two points of interest... 1. The card can be disabled without opening the Mac, simply by switching on the Mac's power...

Bruce, it's been years since I've opened my HD20, and since you mentioned those two tabs, I'd love a refresher. The MacGUI blog says this... But that isn't specific enough. Pressing on them a tiny bit with my flat head screwdriver doesn't magically allow the lid to be lifted. What is your...

Thanks for sharing. Hopefully the chip is authentic, because the price (without shipping) is just under $10. That seller in Florida is great for folks in the US (if the chip is genuine), but shipping fees make it a bad deal overall for those overseas... And that's really why most people...

Where did you order it from? Do you have a photo of the chip you bought? This makes me curious about SOURCING. I see one on EBAY for a cheap price and with nice markings, but two questions arise: 1. Is that photo of the real chip, but you will receive something very different? 2. If the...

I wish we had a schematic of the CC Analog board! But that doesn't exist outside Apple's internal archives. (You'd think will all the leaking that goes on, someone would have leaked those schematics by now!) The web info on the Stereo Mod says to put the same capacitor on the CS5 pads as is...

Absolutely amazing work, Zane. Your ability to design amazing gizmos like this blows my mind! 🤯

@Kay K.M.Mods and several other people who have installed Bolle's clone of the Carrera040 have discovered that there are audio glitches on the SE/30, but apparently not on other Macs like the IIci, when the 040 on the accelerator is being used. I guess it must be a similar problem to what you...

Yowza, Zane! 25MHz 68000 with full compatibility with older software (whatever runs on a normal SE), plus the ability to use a Fast ROM too, all in a super compact size. Without going through all the previous posts, what is the estimated ballpark price?

Where FTP stands for Forced Perfect Termination, using diode clamps. I wanted to explain that because I often need help with acronyms! 😅 In my first video on MacSD, I mention the 3 Termination methods not only because MacSD offers all three but because there are cases when one would work but...

My friend, Kay Koba, posted a link to this insanely great video today on FaceBook, and after watching it this evening, I had to repost the link here on TD... https://www3.nhk.or.jp/nhkworld/en/ondemand/video/3004698/?autoplay It will be available for watching until September this year. A very...

Wow. When did you work at Apple, and in what capacity, Alf?

If everyone outside Japan stopped buying on Buyee, Yahoo Auction prices might be lower! But thank you, Kay, for all your help. You kindly gave me the advice to buy that 575 & 630. I really appreciate it! You also gave me a lot of advice on the Stereo mod, and I am looking forward to doing...

I'm big on performance when it comes to SCSI to SD solutions, and MacSD is really quite incredible when it comes to that. Plus you get all the other great features too, which is amazing. After my SE Reloaded video series concludes, I intend to revisit MacSD (and the new firmware) and also add...

I bought a fully functional L575 (entire computer, with keyboard, mouse and a few CDs) with shipping to my address in Japan on Yahoo Auctions Japan for a total of 9250 Yen in Oct. 2021. Then in Nov. 2021, I purchased a Performa 630, with shipping, for 3960 Yen. (Kay Koba kindly spotted those...
