    Nintendo Famicom Restmods

    Famicom has a CPU tuned to 6502, which was also used in Apple II. I wasn't very familiar with Famicom, but this time I repaired this early model and converted it to RCA output. It may be a well-known Mods, but I will post it. Read my blog for more details...

    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...

    Kay Koba converts an LC575 Back Panel for the Color Classic

    That's an exaggeration! I know the process because it was the second time I did the work. To replace the story, the task is like installing an OS. It takes several routines to work while thinking, but if the setup has already been decided, it is automatic operation. I always repeat this kind of...

    Help needed with dead Mac 512K board

    What the above guys are saying is generally helpful. If the ROM is bad, the checkerboard will come out more beautifully. It's just my experience. In my opinion, Unfortunately, one of the possibilities is that the RAM has burned out. Normally, RAM problems appear in Sadmac, but in your case the...

    Kay Koba converts an LC575 Back Panel for the Color Classic

    Thanks @JDW ! I will explain a little more why I processed it like this: - ABS plastic tends to stretch due to the heat of the band saw, set the saw speed slower. I use the teeth of the cutter instead of the scraper for finishing, but this can be anything as long as it becomes a scraper...

    Mac Plus repair with the ROM-inator Resurrections

    In fact, I have contacted the author several times in the past. Unfortunately I can't get in touch with you right now. Formally making it into a book may be the right path. Everyone wants it too.

    Thx @JDW , There are Japan's own Mac culture, and we are the only ones who know the origins of Mystic and Takaky, which are the origins of this, and we are the only ones who can understand the Dooping Mac that started this is.

    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...

    Macintosh LC 575 “Mystic” logic board recap, install into Color Classic II chassis

    There are Hi-res Mod (13 inch) and VGA Mod to display on 640X480, but I'm trying both. Of course, in the case of Mystic, you only need to raise the horizontal sync signal a little, so VGA Mods is OK. The purpose is to increase the horizontal deflection voltage from 60V to 68.5V. Therefore...

    Color Classic Mystic Upgrade

    Mystic is an upgrade method using the LC575 board, which has the same logic board connector shape. If you want to use the LC475 (Quadra605) for it, you will have a hard time getting the video out due to the design of the logic board. Its video out is on the back, but the LC575 (LC550, LC520) and...

    In tech stuff, what's a little thing that just...bothers you more than it should?

    Right, It looks like a Fake Compact mac for me...lol I worked at an instrument store that doubles as Apple's distributor in early 1990. I was not a Mac person in charge, but I knew the word of Trojan by that time... Isn't it a PC for about the same time? It is not very detailed...
