    Help with capacitor compatibility

    My suggested replacement cap is a FILM type capacitor. Those almost always have very high voltage ratings. And that significantly higher voltage rating doesn't matter at all. Most people who lack a schematic just need to recap based on the stock cap's marked voltage and buy the same or...

    Help with capacitor compatibility

    @keelus My complete Mouser Cart is here, and my video is here. See the text description under the video on Youtube for lots more info! (For US Analog Boards only, not international.) There is a cap kit for the International Analog Boards on Console5 here, but sadly, it doesn't include the...

    SE/30 RAM Banking QUESTION

    According to this LEM page, unless you are installing 17MB, you should be putting the larger sized SIMMs into Bank A, with the smaller sized SIMMs into Bank B. However, when I put four 16MB SIMMs into Bank A, and nothing in Bank B, I get death chimes and a crazy display. But if then put 4...

    So I hear you like overclocking? [BlueSCSI]

    I made some time after work this evening to test all 3 of my BlueSCSI units (2 of which are now overclocked) on a PowerMac 9600/300 with a Buffalo 400MHz G4 (7400) CPU card installed. All were connected externally, with the internal type BlueSCSIs connecting via OverEasy II Rev.B. The minimum...

    So I hear you like overclocking? [BlueSCSI]

    Hi, Folks! I have 3 "high quality" (well constructed) BlueSCSI units that I acquired from @Kay K.M.Mods, each with different processors... After a discussion with @eric yesterday, I decided to proceed with overclocking these units to see what would happen. My rather straightforward method...

    You on Mastodon?

    My first computer was the 128K in 1984; and at the time, I had a 300 baud Maccessories portable modem, which included a nifty soft case... Back then, even that pathetically slow modem cost $140... But it still cost less than the $200+ that was common for 300 baud at the time, and 1200 baud...

    You on Mastodon?

    Nope. :-) Back in the day, I was only into basic dial-up BBSs.

    You on Mastodon?

    I grew weary of FB for the exact same reason. I didn't care for what my "friends" were eating or their chain-mail style memes. However, I chose to say on FB because I live outside my home country and still have a lot of friends and family on FB. It's a way to keep in touch. But more than...

    Snooper 2: Motherboard Pixel Images Extracted! ENJOY!

    Thanks for doing that. Interestingly, it's more of a Mac Plus motherboard drawing than a 128K drawing due to the connectors and the two torrid coils. And yet, the RAM chips to the right of the CPU are clearly from the earlier motherboards. Have a look at the obvious differences... Plus...

    Snooper 2: Motherboard Pixel Images Extracted! ENJOY!

    Thank you! I was actually thinking about just that while taking a shower this morning, prior to reading your post. I installed it in Basilisk II, set it to SE/30, restarted, launched Snooper, and boom! Got the SE/30 motherboard. So I will slowly add these to the opening post so anyone can...

    Snooper 2: Motherboard Pixel Images Extracted! ENJOY!

    https://macintoshgarden.org/apps/snooper-20 I edited my opening post to add that Macintosh Garden download page. It's a great app to use regularly anyway, screenshots aside. Thanks for the link on your website, by the way. A lot of people overlook what kind of caps are best...

    Snooper 2: Motherboard Pixel Images Extracted! ENJOY!

    Starting with this post, I found that Snooper 2 has some interesting motherboard photos, worthy of extraction. If you follow that discussion, you will see that it concluded with the finding that we cannot extract them from the PICT resource of the Snooper app. The only reasonable method of...

    Snooper serial loopback plug

    Although Bruce is probably happy about the extra attention brought to this thread with each subsequent post, it is only right and proper that I start a new thread to address that, which I have done here...

    Merry Christmas to all, and to all a Black Knight!

    @Ron's Computer Videos Spaceward Ho! is one game I played for countless hours back in the day, and it too has special CMAS graphics on Dec. 25th...

    Year End 2022: Seasons Greetings & Best Wishes!

    @Kai Robinson kindly offered us some wonderful well-wishing last year, and with it being Christmas today here in Japan I felt compelled to do the same. Forum membership has grown considerably in 2022. I know everyone here at TinkerDifferent would like to extend a huge thank you and warm...

    Snooper serial loopback plug

    Shift-Return merely opened the PICT resource with the same View by PICT setting. However, it doesn't crash immediately when I first open it, which gave me a chance to click the View menu and choose "by Name" -- that avoids the crash. I also don't see an "Open Template..." command. However, in...

    Snooper serial loopback plug

    After reading your post today, I tried opening the PICT resource of the Snooper 2.0 app using ResEdit 2.3.1 on a real SE/30 (no accelerators) using both a BlueSCSI and a MacSD, running 7.5.5, 7.1 and 6.0.8; but in every case I get a BUS ERROR when I click the scroll bar's down-arrow 3 times. I...

    SMC ROM SIMM Prototype

    I truly hate rubber bands. Using them to secure broken RAM SIMM slot tabs is easy, but they degrade and break after a few months. Some people say to "hot glue" RAM inside the slots, but that is silly when you are a crazy vintage Mac fan like me who often changes out RAM SIMMS! :-) I added...
