    Saving the SE and Plus

    Wellp, I was gonna wash the boards yesterday, but I couldn't. Boards will be washed sometime soon and I'll try and make some detailed videos as I did with the floppy. Yeah, the process I used was to get the images in disk copy format, strip off the 84-byte disk copy header, leaving only the raw...

    Micron Xceed docs on ebay

    Maybe we will see a post from the new owner of the materials, here or elsewhere. Regardless, a community effort to develop a similar product would be neat. I'm proficient with PCB design and design for electromagnetic compatibility, though I don't know how to design the grayscale video circuit...

    Compact Macintosh Value? Plus, SE, SE/30

    Hmmm, I couldn't bear to tear out the CRT and put an LCD behind the glass. Too bad the color tubes won't fit. About the llamas, I meant the way that the Quadra 800 and Color Classic have rounded legs, and then the Color Classic has a "head" that sticks up too.

    Saving the SE and Plus

    Not 100% sure, but the image I used works in Mini vMac, and it does show the happy Mac, whereas incorrectly formatted floppies show the "disk with an X" icon Also in the previous post, when I said you can't use too much silicone spray, I meant that you should use a lot, that it's impossible to...

    Saving the SE and Plus

    Well, cleaning and re-lubricating the SE/30's FDHD drive and head had no effect. I should note that my friend and I are partners in this project. Here's a shot of the SE/30 board. Looks good! a little something sticky on the board, probably cap goop, but otherwise good. Here's the procedure...

    Compact Macintosh Value? Plus, SE, SE/30

    Yeah, I had no idea how much they were worth. I always found the Color Classic ugly. It and the Quadra 800, they kind of look like llamas. Man, I wonder if anyone has fit a Color Classic into an SE case, or performed a color SE/30 mod.

    Saving the SE and Plus

    I'll keep in mind to use the ammonia first, and I'll redo the final wash with 99% isopropanol if it's necessary. Then I'll recap, once I can do an inventory of my machines so I can buy all of the capacitors in one go. The analog boards and power supply look good on all of the compacts I have...

    Saving the SE and Plus

    Just to clarify, the SE is the one with the battery acid spilled all over, and the Plus is the one in relatively good condition. I know the SE board's traces are all probably shot underneath the battery acid, but I at least wanted to clean it to see how badly the traces have been damaged. I...

    Saving the SE and Plus

    I recently picked up 15 or 20 old Macs, including 4 compact models. I've now got an SE/30 that appears to be in great condition, but others are in pretty dire condition. Here's my SE/30. HDD doesn't work and I don't have a boot floppy, but the capacitors look okay and no battery acid on the...

    Compact Macintosh Value? Plus, SE, SE/30

    Thanks for the advice. Your note on pricing, E.C., was very helpful. I bought the machines and I will make another thread about my efforts to repair them. Some of the machines are in excellent condition, whereas others are really poor.

    Compact Macintosh Value? Plus, SE, SE/30

    I recently stumbled upon a collection of 68k Macs for sale: two Plus, an SE, an SE/30, along with 4 IIsi and 4 LC. Plus a few Apple IIGS, disk drives, etc. I'm a pretty experienced designer of PCBs, so I know how to inspect the condition of the logic boards and make sure the machines are in...

    Compact Macintosh framebuffer/video out design?

    I've managed to collect the developer notes for a few machines, but unfortunately I've never been able to find the notes for the SE or SE/30. Thank you for your great response, bigmessowires. Your website has some great info as well. Of particular interest was a link I found in the comments...

    Compact Macintosh framebuffer/video out design?

    Thank you for the info. Can anyone provide any info on the memory access timings for the SE and Classic? What about the Classic II? Did it have an integrated display controller similar to the one included on the IIci or IIsi? I have confirmed that there are VRAM chips on the SE/30 logic board...

    Compact Macintosh framebuffer/video out design?

    Hello all, First post here. :) I am trying to understand the video output circuitry of the later compact Macintoshes. I understand the Apple II's design... the RAM can run at twice the speed as the processor, so the video/DRAM refresh circuitry and the 6502 can interleave access to the...
