    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    And much better than the Levco (SuperMac) SpeedCard I own, and better than the Radius Accelerator owned by @techknight too! At this point, I will tag @BFEXTU because he and I shared a lot of private messages in the summer of 2022 regarding the SpeedCard. He was a SuperMac engineer who had the...

    I just finished watching the video to the end. I enjoyed seeing the commentary by Ray Arachelian, creator of LisaEM. He passed away in early 2023 at the age of 51. I also see you have an interview with Adam Rosen, who passed away in August 2019 at the age of 53. And perhaps one of the best...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Here are 48kHz 24-bit WAV files using WarpSE-ROBUST and the Stock SE, recorded with my SONY D100 at the Headphone Jack: https://drive.google.com/file/d/1IPqGUVvOYSr2pTbw-GWRyi3q4qyWp09N/view?usp=share_link The Mac SE was booted into System 7.1 with extensions enabled. I used the TwistedWave...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    First and foremost, what I'm about to say has nothing to do with the audio glitching when WarpSE is active and running ROBUST firmware. That has clearly been established, and Zane has written extensive thoughts about how he intends to proceed. I will now provide more details about the...

    Case for Androda's Mac Portable VGA Adapter

    Thanks for confirming my eyes weren't deceiving me when I viewed your earlier photo. It did look vertically stretched to me.

    I'm only 15 minutes into watching it and I must say that I'm impressed by all the key players at Apple that agreed to be interviewed. Great stuff!

    Case for Androda's Mac Portable VGA Adapter

    We don't get hurricanes here in Japan, but we do get Typhoons. I still recall vividly, 20 years or so ago, setting a date for a BBQ at my Australian friend's home here in Japan, and it just so happened on the scheduled day that a Typhoon hit. Were we going to let that stop us? Not on your...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    The final word on "good recordings"... But it largely shows you what my previous video did. And it makes the stock SE audio stuttering all the more clear. I supposed the rest of you hear that stuttering too, right? In any case, it shows ROBUST doesn't playback the Tetris theme music as...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    @Zane Kaminski Thank you for the extension technical explanation. Your knowledge of things is impressive. It just blows my mind. That is of course why WarpSE is mind blowing too. I have nothing but high praise for the work you've done thus far. Bravo! 👏 I plan to do more testing on my lunch...

    Case for Androda's Mac Portable VGA Adapter

    Thank you for the photos. It's hard to tell from the shooting angle and lens distortion, but is the mirrored screen proportionally correct? Or is it slightly horizontally smashed like it appears in the photo?

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    On the first few recordings of Winter Games, yes, I agree. But not with Tetris. I tested with headphones, my 5K iMac's speakers, and my 16" M1 MBP speakers, and while it's easiest to tell the difference with headphones, I can hear the difference even using computer speakers. With that said...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    My audio tests are done. In the video below, I compare the Stock SE audio with the Levco SpeedCard (terrible!) and WarpSE with NoWaitState and Robust firmware. Expand the text description on YouTube and you'll see it's fully indexed so you can jump to the individual timestamp sections with...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Because "NoFixedWait" firmware is already flashed to my WarpSE, I spent my lunch break testing audio. I really couldn't hear audible distortions through the speaker, so I wore headphones to check Spectrum Holobyte Tetris & Winter Games. Honestly, I really can't detect bad audio during the...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    I was using real PC. I believe it has an Intel processor running Windows 8 (Japanese language version), but I'll need to confirm that later since I'm starting my work day now. Okay. This evening after work, I will test audio on Spectrum Holobyte Tetris and my mainstay, Winter Games. But in...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    My first test, prior to flashing, confirms the audio crash, but only with certain sounds. Have a watch... And here's a video of my first flashing experience, using FAST SCSI firmware, which seems to have cured the sound problem, at the expense of a mouse so jumpy it's not really usable: I...

    Good TFT for a 512K case ?

    Good TFT for a 512K case ?

    So it would seem almost all problems have been solved but the biggest one — reflections. The stock CRT is anti-reflective. I've seen photos of people who cut the front off a dead CRT and mount an LCD behind that, which is really neat, but that skill goes beyond what most people would likely be...

    ReStuff 2

    Not sure what "WebAssembly" is but all I did was click Eric's link , then I used Stuffit Deluxe 16 on my modern Mac (runs even on Sonoma!) to make a "Legacy" *.sit file of something (which makes Stuffit 5.x archives), then I dragged that SIT file onto the emulator, then I clicked the button. I...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Because it's late here in Japan right now, I will begin my testing tomorrow on my lunch break and after work. In the meantime, please let me know if everyone is using Speedometer 3.06 or 3.23. That way I can make sure to use the same exact version everyone else is. Since there was no comment...
