    SMC Fat Mac Switcher

    https://macgui.com/usenet/?group=9&id=1310 Here's a little info, but I don't know if this is correct, I'm not very familiar with this generation of Mac software, so I think it's a discovery for users!

    SMC Fat Mac Switcher

    Thank you James! I was worried because your reply was long, but I was relieved that it was all praise:ROFLMAO: It's actually a device I built just for my own curiosity. But it worked so well that I can safely recommend it to everyone.

    SMC Fat Mac Switcher

    Many of our products have simple and interesting ideas, but this one is even simpler and innovative...??? But look anyway! Jun 12, 2023, New Instruction here: https://mega.nz/file/LLImBL7Z#DRn5djM4Oa83K4aRX2TWIC0V4AnEWO3MmgY19St541I https://ameblo.jp/keroxiee1016/entry-12803881976.html...

    Satanic SE/30 Project

    I was surprised that I had knowledge of Open Firmware at that time, But now I have forgotten most of it, good luck!

    Satanic SE/30 Project

    I was asked by Sean Malseed (Aka @Action Retro ) about overclocking the HARMONi, so here's a summary from my old notes. *I didn't have much time, so I used Google Translate, so I think some expressions are bad. Please understand. After getting the HARMONi500 card, I verified the PLL...

    SMC SE Analog board and Neck board Resurrections

    I know Bolle made this. he always does a great job. However, I thought that 640x480 display was not possible. In that case, the usage is quite limited. I made a SATANIC SE/30 before, which can display XVGA rather than VGA. This method also works for SE/30 logic boards. *video card required On...

    MSX 64KB RAM Card and ROM Card Design

    I was the first MSX generation, but I was using NEC's PC-6001, so I wasn't interested in MSX. The same goes for Famicom. Exactly around 1980-82. @Stephen and @Drake at SMC were specialists in Gameboy and other game consoles, so I learned a lot from them and there are more things I want to try...

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    That's weird. Mine worked! But I switched to IIx ROM now. If I have time, I'll check the ROM Ver of my MacII. MaxII and Mac II fx are heavy and huge, they always sleep in the warehouse😴 I will send you a dumped ROMs if they were special ROMs for Japan models.

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    Try it on system 1-2. Kanji Talk Talk 1.0 is System 3.0. *I made a mistake in my Twitter reply The Japanese Mac II's onboard ROM is the same as the US version. I used MacII with System7.0.1, no problem.

    Mystery Apple KanjiTalk Font Card (NuBus) [630-0174-A] Does anyone recongize this?

    I just had a question from Steve M. and just talked to him about it. The Kanji-ROM Card was bundled with the Macintosh II and is a legacy of the System 2 generation. This was abolished after Kanji Talk 1 was released. Kanji Talk 1 is Japanese ver. of System 3.0. To use this Kanji-ROM card you...

    SMC ROM SIMM Prototype

    Thank you for great animation work @retr01 ! that reminds us of the good old days of computer games in the 80's 🕹️ The first half feels like an elevator action. Unfortunately, my office isn't a splendid building like your anime. Can't miss the place where rainbow 🌈 colors are featured in...

    SCSI RIDER, SCSI Device to Logic Board 50pin Adapter

    @JDW Yea, in that case, it is necessary to make the PCB a through hole and install it vertically. like a hitchhiker. However, on models other than the SE/30, such as the LC, there is a slight contact with the ADB cable connector, and a small problem. Not all of these can be resolved. Ahhh, I...

    SCSI RIDER, SCSI Device to Logic Board 50pin Adapter

    What I showed you is my scrap designed plan B that I had already made;) I don't think I will develop this product any further. As I said last time, I'm not really interested in daisy chaining products as you said... good Luck!

    SCSI RIDER, SCSI Device to Logic Board 50pin Adapter

    Are you talking about the hitchhiker with the black gray case that I own? This case is designed to fit all 2.5inch hard drives and is compatible with 2.0mm pitch 50pin pin headers. If the 50 pins you were thinking of were 2.54mm pitch, that's not the case. Whereas SCSI RIDER 2 DB25 is 2.54 50...

    SCSI RIDER, SCSI Device to Logic Board 50pin Adapter

    SCSI Rider2 DB25 Ver. *lost work OK, this was Plan B, with a female DB25 placed at the back. This is for daisy chaining. I'll update this later, but I'd like to point out some caveats. As I said last time, I know a few my friends have wanted this. But sorry guys! I myself am not very...

    SCSI RIDER, SCSI Device to Logic Board 50pin Adapter

    @retr01 I see, actually I have a hitchhiker. But I never felt the need for daisy chaining. However, as I wrote before, the design to attach the out of DB25 to the rearmost is almost completed. If I have time, I will fix it and show you....😄

    SCSI RIDER, SCSI Device to Logic Board 50pin Adapter

    @retr01 Right. Actually, we considered until the end whether to use DB25 or IDC50 for the rearmost connector, but we adopted IDC50. We have adopted as many possibilities as possible. But the DB25 version is actually complete...😅 A right angle might be interesting, but what do you use it for?
