    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Not sure why the Xilinx is dead - there are plenty on Mouser, and they're not listed as NRND (ie, when the manufacturer is taking final orders)...

    Just ordered a Quadra 950, any known caveats or advice?

    Don't suppose that floppy bezel is still available is it? I have a Q950 and i'm lacking that, the PSU bracket and floppy drive.

    Sleepy HD

    Usually Apple HD SC Setup would do the initialise of your drive, loaded from the utility disk. However, if your drive is dead - 2.5" SCSI drives in working order are hard to find might it be time for one of these: https://androda.work/product/powerbook-bluescsi-version-4-f1-tba-pb-v4/ perhaps? :)

    Battery damage on SE/30 - Thoughts?

    The good thing about the SE/30 Reloaded from @Bolle is that the Pick & Place and BOM are available on GitHub for you to be able to have JLCPCB pre-populate the rear of the board with the fiddly parts, leaving you to do the rest on the top, which are considerably larger.

    Battery damage on SE/30 - Thoughts?

    Yikes - the RTC chip looks like it's been eaten away :( It may be a good candidate for an SE/30 Reloaded build - i have a spare RTC chip i could send you, if you wanted to go down that route, but i definitely think it's the best course of action.

    Logic Board - Macintosh Classic Reloaded

    Not at all! Don't worry, it will be released on github as the gerbers and the sprint layout this year - just gonna recoup some costs first :)

    Logic Board - Macintosh Classic Reloaded

    Unfortunately, i don't have a board view, as such, it was created with Sprint Layout and currently it's not been released as Open Source (yet - it is planned this year, though).

    Recommendatons for a new reflow station / hot air gun?

    Never had a bad experience with my Yihua 959D - but the Atten would be my choice now, if i had to start from scratch.

    How to: Build an External Power Supply for Atari 520ST (Using Parts from Amazon US)

    Gotta say, i really love the RT-65B - i made a bench supply for testing SE & SE30 logic boards, using one of those. Still keep meaning to get another one to shove into the original Amiga power brick.

    1987 Macintosh Plus (Platinum)

    Did a bit more measuring: between pins: 1 + 4 = 1.5 ohm 1 + 5 = 1.5 ohm 2 + 3 = short 2 + 7 = short 2 + 8 = short 3 + 7 = short 3 + 8 = short 4 + 5 = short
