    "Spicy O'clock" project has started

    We have updated some.The Ver1.2 PCB has already been ordered and will arrive at us in about a week. Some will be distributed to testers and then the product will be released. - The switch has been replaced with a pin header. It will not break down, so you can use it with confidence for decades...

    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...

    Mystic with Spicy O'Clock! 42MHz

    Hi, I used 70Ns Vram for my Mystic. Plz see my blog for the details: https://ameblo.jp/keroxiee1016/entry-12614308377.html @JDW said you are familiar with VRAM:) and you built them. I'm a little busy, so I'll do benchmarking and validation at another time. At that time, I will also replace the...

    Mystic with Spicy O'Clock! 42MHz

    Hahaha, this is my takky(No.2). Do you think this is slow :LOL: I love the fast things, but 68K is a wasted dream, I love them. I enjoy 68K more than PPC now😊

    Got my Color Classic back

    It's very funny, At that time, we Japanese thought this was not cool, and it was natural to peel it off....lol However, it is an interesting part of the world that it becomes cool over time when it is not cool. I like it now 😂 There was a remaining decals with my warranty card. This is the...

    Mystic with Spicy O'Clock! 42MHz

    I have two Mystics, which is the Mystic (No.1) that I modified a while ago. Tested for "Spicy O'Clock!", the original post is here Spicy O'Clock! is adjustable oscillator used silicone oscillator chip. I think it's the first time it's used on a 68K Mac. It has a variable range from 35MHz to...

    Not only vintage Computers

    Black Bard is actually my friend P-car. That is the beginning of attached pic, and it is a real car that actually appeared as Black Bird in a Japanese V-cinema movie. He has been driving for over 30 years since his new car and is still racing. The Wangan Mid-night is actually similar to our life...

    Not only vintage Computers

    ROM-inator Resurrections is now on sale, but this is another resurrection. This was an even grander plan that took seven years, but required more technology than modifying the Mac. I made it almost myself. Of course, I also borrowed the help of a friend. It is controlled by the latest ECU called...

    Performa 475 audio issue

    I Agree with Mac84, Perhaps... there is a problem with the sound chip itself. I have an LC575 and an LC475, The same is true for CC, which is a 030 machine, but the low-cost Macs of that generation usually have similar designs. If you try to remove the sound chip even if it doesn't look like a...

    "Spicy O'clock" project has started

    I've created an overlap to make it easier to use. 1: SL Mode 37.96MHz to 41.76MHz 2: LC Mode 41.79MHz to 46.48MHz 3: HT Mode 45.9MHz to 51.49MHz In the actual product, the switch is abolished and replaced with a header pin and a jumper pin. This means less deterioration over time and less...
