    shipping from Japan

    Hi there! I have purchased 2 times from buyee.jp and they pack well (or at least they have done a good job) IF you are still concerned you can pay extra to buyee.jp directly to re-repack your items to have more peace of mind. So far the only issues I have had from japan is that the 2 boards I...

    Mac SE memory management

    +1 to what @JDW suggests -- also check http://www.applefool.com/se30/ (long read but worth it) -- you might want to try working with system 7.0.1 basically uses less ram with the features that 7+ has

    Rolled the dice on an SE/30 from Japan, salvageable?

    the diodes are straight forward to figure out, and the RTC iirc there are replacements for them already. you can check for part numbers in this sheet

    Rolled the dice on an SE/30 from Japan, salvageable?

    you have a bunch of traces gone, you will have to take out the rom slot also and see how bad is underneath, the RTC looks gone but I might be wrong; best thing is to start cleaning it as much as you can and remove the old caps, THEN you can see the amount of damage you have fwiw not all hope is...

    Odd Sound Issue on Recovered SE/30 Simasimac

    the garbled sound doesnt have anything to do with any of the audio system, you will have to check all the digital and analog connections from the processor to all the parts -- there is a matrix that you can use from the digitized schematics Check...

    Odd Sound Issue on Recovered SE/30 Simasimac

    the garbled sound could also be a Digital (or analog? cannot remember) trace from the processor with contact (continuity) issues. you might want to check those

    1rst of all, congrats! -- yet I can see some corrosion on that capacitor C12 -- do change them asap :)

    Odd Sound Issue on Recovered SE/30 Simasimac

    it could be the amplifier IC below Q1 and Q2 (cannot recall the name, its surface mounted and has 8 pins) -- next to that blue cap. It would be helpful (for you) to clean all the flux with isopropyl alcohol also. Finally -- does the same noise happens with your headphones?

    ha!, coincidentially enough I have a LC II case which I plan to install a LC475 motherboard in it to make a rogue LC II 😏 -- thanks for checking out the video! :D

    Building a Micromac Performer SE from components

    Hey Everyone 👋 Me again, on this episode I show you how to build a micromac performer accelerator card for your Mac SE -- here we convert the Mac SE to a "Mac SE++" which has a 68030 processor with FPU and MMU the "++" part is because is not a SE/30 as there is no way still to add more ram...

    Macintosh PortraitDisplay Recap and Geometry Adjustments

    Alright, it took me a bit to do this but here is the 2nd part! I tested this out with another video card and with B&W works well. I then went ahead and changed the monitor + the original (defective) card and with B&W works "well" -- in regards that you still see the background as blue 🤔...

    Macintosh PortraitDisplay Recap and Geometry Adjustments

    hey @JDW ! Thanks for checking out the video! :). That's a great point, I didnt show how the monitor looks with a different video card :(. But the plot gets better! -- with the same video card, I realized that I had the monitor set to black & white, that video card lets me set the video to...

    Macintosh PortraitDisplay Recap and Geometry Adjustments

    Not sure where to place this (mods let me know if its fine here, else I can move it :)) The Apple Portrait Display, released in 1989, was a groundbreaking monitor that broke away from the conventional 4:3 aspect ratio of its time. Designed with productivity in mind, it featured a tall 15-inch...

    Macintosh Portrait Display Repair - Smearing/Pulsing Image on Screen

    thanks for the insights! -- the fan is barely noticeable, actually I was surprised when I saw a fan when I opened it :).

    Macintosh Portrait Display Repair - Smearing/Pulsing Image on Screen

    Interesting @JDW I didnt think about the ESR -- FWIW the portrait display on the inside has a fan I imagine to recirculate air -- while I was adjusting it it was getting warm, not 85C warm but nonetheless warm.

    Macintosh Portrait Display Repair - Smearing/Pulsing Image on Screen

    Thanks for sharing this list! -- I went ahead and purchased the caps from the mouse project and replaced the signal board and neck board, Unfortunately the sweep board I just didnt. The reasoning behind is because the caps on your list are rated for 85c which are fine for the signal board...

    Reverse Engineering the Macintosh IIcx Logicboard

    WOW -- just like elbow grease sanding or is there any special technique? -- I am mainly asking because with elbow grease one can sand more on some parts than others on the surface. Quite impressive though!

    Reverse Engineering the Macintosh IIcx Logicboard

    retro-reviving this thread but out of curiosity, how do you get layer 2 and 3 connections from a scan? I can understand layer 4 and 1 but the internal ones, how does one do that?; with X-Ray or smth?
