    Compact Mac's feet project

    Many compact Macs have lost their feet or have been hydrolyzed to dissolve. Also, many substitutes are completely different in shape. So we are working on a new replacement foot. It takes a lot of manual work to make the same shape, and it takes time to make a beautiful shape. The target amount...

    Mac Plus repair with the ROM-inator Resurrections

    Hi there, A friend of an Apple collector living in my neighborhood asked me to repair his DynaMac. This was originally a special Mac 512K for Canon and Apple with a Japanese Kanji ROM, but was later upgraded to the Mac Plus. As you can see, it was a checkerboard, so the ROM defect was obvious...

    ROM-inator Resurrections

    It's well known to macintosh enthusiasts that on Vintage Macs, ROM upgrades are needed to be easier to use than CPU upgrades and memory expansions. BMOW sold the first ROM-inator as a kit for Plus, 512k, 128k, but now it is open source and you can only make it yourself. To produce it, you need...

    "Spicy O'clock" project has started

    It's a bit early to announce this, but @Stephen has designed a beautiful PCB from my schematic, so I'll publish it here. See my blog for the base. I improved and used this oscillator sold by a Japanese company called Akizuki Denshi, but I improved it to make it even easier to use...

    PSU hack for IIci and other soft switch Macs

    I made this PSU hack a while ago. Other guys are doing the way to control soft switches with transistors. I made this in a way that doesn't require a + 5V pullup. Specifically, a photocoupler is used. This method is also compatible with G2-PowerMac. Please try it in case of PSU failure. I'll...

    Macintosh II with ROM-SIMM

    It's been about 2 weeks since I got the Macintosh II Rev.B, but I've replaced the 8 RAM sockets on it and have been recapped. This time I couldn't stand it and tried to see if the ROM-SIMM pattern hidden under this ROM socket worked. The ROM used is IIxIIcxSE30_512k.bin. I tried other ROMs...
