    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, I sampled a normal boot chime and created a file that I can share. https://mega.nz/file/beQxEIjb#bRlkG6YGcbq_3XMWO7cmsONhSSqMHjgOgxgLSdqEgok This is a RAW file, but it can be programmed with the ROM-inator Tool as it is. * Tool can recognize raw files. About a Happy Mac Icon, There are 12...

    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...

    Possibility of complete redesign and modern manufacture of LC-LC475 power supplies

    I saw the first post again, but Mr. F said that it was the PSU for the LC series, but not the LC475 :ROFLMAO: I may not have followed the topic:LOL: I don't have a Mac up to LCIII, so I can't actually verify it... But I think all 040 machines need -5V if Mr.F had a LC475(?). I add that all my...

    Possibility of complete redesign and modern manufacture of LC-LC475 power supplies

    Oh I didn't know -5V unplugged and boot, Can it certainly boot on the LC475? If that is true, you have to apologize for the wrong information point 😅 However, when I checked the wattage of the small AC-DC adapter (same as Mr.F's link) I had, it was 32W, which is not enough for the rating...

    Possibility of complete redesign and modern manufacture of LC-LC475 power supplies

    Genuine PSU specs: +5V x 4.75A = 23.75W +12V x 1.0A = 12W -5V x 0.075A = 0.37W The wattage for each volt your Mac needs is listed above. Total wattage : 36.12W *I think actual total wattage is more bigger about 40W or more. The voltage must be generated at a volt number higher than 12V, when...

    Possibility of complete redesign and modern manufacture of LC-LC475 power supplies

    Unfortunately, this PSU cannot be used. To know all the currents used for + 12V, + 5V, -5V, refer to the original PSU label. W= V x A In the case of LC475, a total PSU of about 45 to 60W is required. *I used 90W...I think it was😅 Use an inverting regulator to generate -5V. Furthermore... one...
