    SE/30 Y3 Crystal Replacement Recommendation?

    This will be my last reply until Will replies tomorrow. When you have no ground at all, you will often see ghost signals on a scope -- signals that aren't actually present at the point you're touching with the tip of the probe, but in fact are picked up from elsewhere. (60Hz, for example, is...

    SE/30 Y3 Crystal Replacement Recommendation?

    Will is across the globe and already in bed, but he said he needs to do some testing tomorrow morning his time so he can reply to this thread then.

    SE/30 Y3 Crystal Replacement Recommendation?

    When you watch that video I linked for you, ignore his use of a buffer and hex invertor. That isn't relevant. I merely linked it for you to show how shortening the GND lead worked wonders in cleaning up his measured waveforms. I can only say that lengthening a scope probe's GND lead should...

    COLOR CLASSIC LCD CONVERSION VIDEO!!

    @nottomhanks The video all serious Color Classic owners have been waiting for! Thank you, Tom! The main reason I don't have the kit is because they ran out of that edition LCD at the time I was inquiring with the creator. And I've not heard back from them about their new kit, so I guess they...

    SE/30 Y3 Crystal Replacement Recommendation?

    Adding a long green extension lead like that for Ground is a huge no-no when making HF measurements, but I must go further to say that your current black ground lead is still too long... In the video I linked for you, you will see the video creator shows he initially used the same black...

    How the Macintosh Plus helped make Star Trek history! #VFX

    Fantastic research and info, Ron! This needs to be shared with Star Trek sites to make it really take off. A little disappointing it was a Pee See that did the display creation, but not too surprising for the time. I remember vividly when I first saw the film, thinking to myself, that's not...

    SE/30 Y3 Crystal Replacement Recommendation?

    Before discussing the details of waveform shapes, we need to assess if your scope probe is using a short or long ground lead, which is discussed in the following video:

    A very special Mac Portable

    I like the fact you enjoy that model iMac because it really doesn't get enough love. That metal Arm for the display was and still is so very awesome! Apple doesn't get enough credit for that design. And unlike monitor stands from Apple that cost a kidney to purchase, that metal iMac arm was a...

    Radius Rocket & SCSI Booster Clones

    Replies came as I was going to bed last night, and I'm at work now. Will consider use of RocketShare software later, although it will be for testing purposes only because I have no practical use case for a Mac-inside-a-Mac. I only want to use the Rocket as an accelerator. And I say that with...

    A very special Mac Portable

    I too was a MacUser subscriber since the 1980's. Not quite from the Premier issue, but close! My subscription was rolled into Macworld during the merger which took place in 1997. I continue to get the digital version of Macworld today. Thank you for watching and for your kind words. If your...

    Radius Rocket & SCSI Booster Clones

    That's why I hope some people who have the vintage Rocket and vintage SCSI Booster can chime in. My Rocket is vintage (ASIC model), but my Booster is Max's clone. I send OlePigeon a PM on the MLA because I know he has both. He said he would check.

    Radius Rocket & SCSI Booster Clones

    I've never used RocketShare. I've only used RocketWare because RocketWare makes the Rocket act as an accelerator. RocketShare makes it act as a second Mac, or so I've read. When the Mac finishes the RAM checking, it loads RocketWare and then reboots. That is normal. So in light of that, I...

    Radius Rocket & SCSI Booster Clones

    I have Rocketware 1.5.1 installed (you can see it loading in one of the photos in my previous post). But if there is a specific SCSI Booster set of software, I would like to learn more where it can be downloaded.

    Radius Rocket & SCSI Booster Clones

    I purchased a SCSI Booster for my ASIC edition Radius Rocket (33MHz 030)... It includes a standard DB25 for external drives, which is nice. The DB25 connector doesn't stick out enough on my IIci, so I couldn't connect anything at first. But I solved that problem by purchasing a DB25...

    A very special Mac Portable

    Good call on the lowercase "g" there. :D Seriously though, after watching the video, was there anything in particular other than the space scenes that you were not aware of before you watched the video? I'm just curious because most people just tell me if the like or dislike (yes dislike) the...

    [SOLVED] No Dark Castle on Mac Portables?

    The amusing thing is, v1.2 from Macintosh Garden includes this compatibility chart which mentions the Portable... But I confirmed in System 6.0.8 that chart is wrong (at least for the M5126 Portable) because I get a garbled screen when Launching Dark Castle v1.2 without the hack. With Ryan...

    [SOLVED] No Dark Castle on Mac Portables?

    Thanks to Ryan Schmidt's brilliant ResEdit hack given to me on FaceBook, I now have dark castle working on my Macintosh, portable, and this is perhaps the first version ever to work on that Mac! Here is what Ryan told me... Dark Castle contains code to decide whether to make a centered window...

    [SOLVED] No Dark Castle on Mac Portables?

    @Mu0n Thank you for conforming Dark Castle will NOT work on Portables. :cry: But it's so terribly strange that it works flawlessly in Basilisk II on a 640x480 pixel display, emulating a IIci. One fellow on FaceBook told me today his real IIci runs Dark Castle just fine. Which raises the...
