    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...

    First official C64 in 36 years

    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...

    First official C64 in 36 years

    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...

    First official C64 in 36 years

    @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...

    Budget Oscilloscope Recommendation?

    @Trash80toG4 I purchased the Rigol DHO804 in Dec. 2023 for $358.66 (free shipping to me in Japan) from this EEVBlog-recommended seller: https://ja.aliexpress.com/item/1005008242029352.html As you can see, the price is higher today from that seller, but searching for the DHO804 on AliExpress...

    Budget Oscilloscope Recommendation?

    The lower your scope’s "bandwidth" (e.g., 50MHz scope, 100MHz scope, etc.), the more your measured digital squarewaves will be shaped like sinewaves, and the smaller in amplitude the waveform will "appear" to be. The rule is to have a scope that's 5x (or even more) the bandwidth of your...

    sit - Create StuffIt archives on Unix systems

    Exactly. But I guess it’s technically Apple’s fault for having started it with “Empty Folder” back in the MFS days and continuing it with “System Folder”. Even though the Mac was all about icons and a “graphical“ user interface, they still wanted to reinforce it with a word. Even so, it’s a...

    sit - Create StuffIt archives on Unix systems

    Why were those annoying “ƒ” characters used in folder names back in the day? I never saw any logical reason for them to be used, and not every company used them.

    TinkerDifferent.com Retro Proxy

    Short video showing my first test of the Retro Proxy on my 16MHz 68000 processor Macintosh Portable running System 7.5.5 and MacTCP, 5MB RAM, with MacWeb 2.0. (I later tested in S7.1, and while the load time was the same, version 2.0c fixes the black problem mentioned in my video below.) First...
