    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    BTW, I checked and found that this forum already allows moof and dc42, so it makes no sense to disallow support of dsk, so I added it. Now everyone can upload *.dsk images without name changes. You can see that in the attachment to my message. Just reload this web page in your browser to see...

    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    Thank you, David, I will try your disk image on my FloppyEMU tonight after work. Desktop Manager has nothing to do with it because I tested with and without it, and my Portable still would not Auto Sleep under 6.0.8. I will just delete the last 4 characters of the filename as shown below...

    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    I have a MacEffects RAM card which I have artificially limited to 5MB by way of not running the required jumper. (Limited RAM is painful under System 7, but that horrid 26% performance drop when using >5MB RAM is even more excruciating.) If you have a disk image you don't mind sharing with me...

    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    Do you have a BlueSCSI v2 or spinner drive? Do you have a lead acid battery or Battery Eliminator? My BSv2 is resistor modded to avoid wake-from sleep issues, but I don't see why that would PREVENT sleep, especially when I can sleep under System 7.1. But I am glad your testing does show that...

    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    Just to ensure this thread isn't left dangling in the wind until the end of time, the implications of my previous post are: 1. I cannot confirm if the v1.3.1 "Portable" Control Panel blocks Auto Sleep under System 6 because, for reasons unknown, my 5126 Portable refuses to sleep while booted...

    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    I'm now at home and here are my test results. Booted into System 7.1 with version 1.3 "Portable" Control Panel (stock from Apple, without any ResEdit hacks). Of course, I can hear that bothersome "pop" sound every 10 seconds in this case. Computer will sleep after 1 minute with PBTools, even...

    Starting my Compact Mac Vintage Journey with this SE modded to SE/30 project.

    Nice photos and video! To continue our conversation from the YouTube comments, you were saying you want some vintage upgrades and are considering offerings from @Bolle or @zigzagjoe , both for an accelerator and for grayscale (or possibly the color LCD kit). You also mentioned Ethernet. If...

    Macintosh Portable: "pop" noise every 10s from Speaker & Headphones

    I am still at work and the Portable is packed away at home. If I have time after work tonight I can boot my Portable into System 6 and use the v1.3.1 Control Panel to ensure settings are correct so it will try to Sleep automatically. I've never tested that because I don't have a Battery...

    VOLTAGE DIFFERENCES among SE & SE/30 Analog Boards

    You are asking about the 74LS38 VCC Pin 14 voltage, but I don't have the EU edition Analog Board currently installed right now to test. Even so, before I do any board swap to perform such a test, note that the voltage levels at the Analog Board are higher than what my Mac-O-Meter shows at the...

    VOLTAGE DIFFERENCES among SE & SE/30 Analog Boards

    Yes. Everything is exactly the same in each of the four tests except the Analog Board.

    VOLTAGE DIFFERENCES among SE & SE/30 Analog Boards

    I have 1 Analog Board that came with the Mac SE @Kai Robinson very graciously sent to me in the past (from the UK), and I also have 3 other Analog Boards that I use with my SE/30 machines. All Analog Boards have been recapped, trace-repaired, and have the same Noctua 60mm fan installed. The SE...

    First official C64 in 36 years

    @ClassicHasClass Someone posted the content of that letter in the the C64U group on Facebook and I read it prior to seeing your post. It basically said when I was thinking the whole time. Namely, that users of the Starlight edition, mostly complained about keyboard flex and because of that, I...

    I watch the timestamp in your video and here is what Chuck Peddle said… “Steve wanted $300,000 for the company, but Tramiel wanted to give him $50,000.” That seems to give evidence to what I was thinking previously, that Steve would have sold the company if the number would’ve been big enough...

    Just imagine if Jack had added one more zero to that number though. Seriously. Two young guys still in the garage at the time, with no knowledge of what the future would necessarily bring. The larger the number, the more likely they might have considered it, despite having disliked Jack T...

    Indeed, I agree that he did not make that specific comparison. See the video interview posted by @muse here. Jack had the Atari ST right in front of him. Too bad the quality is so low because you can't see what's on screen, but he's using its GUI in that interview, and also, he makes no highly...

    The history that I have read is not clear on that. I keep reading something about the deal having not happened only due to a mere $15,000. But if what I read about Jack being a cut-throat businessman are true, then perhaps it could be said that his intentions with the then-in-the-garage (and...

    Jack Tramiel himself, in multiple interviews, would always compare his computers to his competitors, especially Apple (the company Jack almost bought when the two Steves were still in the garage). Jack continue to make those comparisons even when he later moved to Atari, basically emphasizing...

    @muse I didn't have time to watch your linked video until now. The resolution is absolutely horrendous! :LOL: But the content was great. I was absolutely rolling at the very end when Tramiel shook the interviewer's hand and then immediately stood up and walked off the set! He was a busy...

    Yes it can play really bad sampled audio, and that's why your term "crude" is 100% correct because I've heard those sampled audio sounds — especially Ghost Busters (aka, "speech busters") — and most of the time you're replaying it to figure out what was spoken. :-) When I got the 128K Mac in...

    @iantm I had neither of those 8-bit computing platform in my youth, as our family's first home computer was the 16/32-bit hybrid 68000 Macintosh 128K. I only got into the Apple II series with the IIc that was donated to me by some extremely kind people in our community. What's most...
