Impossible to know because only Kay has one of those new overclockers right now. But I suspect VRAM speed may be a limiting factor at some point. I thought it has been the limiting factor in my own overclocking attempts beyond 50MHz, but now I have discovered a 68040 cooling issue. I am...

You are the first person who has told me you have a similar setup, and I truly look forward to the result of your test. Please note that you can download MECC Computer Inspector, which has the same joystick calibration program that I use here: ComputerInspector (MECC 1.0).dsk

I posted about this over at the Apple II Enthusiasts group on FaceBook, and I also sent Henry of ReactiveMicro an email, but thus far I've not been able to determine the cause of the problem I am having, which I described in detail in the following unlisted video on YouTube... PROBLEM QUICK...

Drake you truly gave Philippe a "leg up" in his repair! :-) @iPhil64 Great job! I've done chip repairs like that, and depending on the chip it's not too fun to carefully scrap away the black body of the chip to reveal more of the leg stub in order to solder something to it. In my case, I...

I answer that question in my new video here. :)

My Part II video on this topic turned out to be longer than I thought, but it's fully indexed so you can jump to the parts which interest you. Even so, it's highly edited such that all the boring stuff is left out and what remains is only the juicy meat. :-) This really is about how useful the...

Paul Hagstrom from the Apple II Enthusiasts Facebook group very kindly provided me with this PDF, which I uploaded to Archive.org for preservation and subsequently linked here on TinkerDifferent. It showcases the complete Apple product line being sold as of the summer of 1993. My main interest...

You mean these holes? The Before, After and Combined images below seem to indicate what I suspected might happen -- overshoot of the thermal paste across the glue, thereby compromising the glue in places. I've bought all the materials though, and in my case it is a square 040 with no...

Thank you for the details. @eric already very kindly made a BlueSCSI compatible version of Total Replay here: https://mega.nz/folder/8hA3AQCJ#pWUq92L70yDXlogy9lk5Dg/folder/gsokHTRC I was thinking about doing a video to show others how to use Disk Jockey to do that. Even so, Eric did not use...

@OneGeekArmy Please forgive my ignorance because I'm most likely overlooking something obvious, but I trying to figure out how to use Disk Jockey 2.5 to create a BlueSCSI compatible version of Total Reply 5, which is a 32MB ProDOS image. I started by setting the capacity to 32MB... Next, I...

For now, go right ahead!

@Kai Robinson I've never been ashamed to say I like Dark Mode, and I still prefer it to this day. However, for lovers of Light, there are definite benefits to the New Light Mode that should hopefully bring it out of Beta and into mainstream usage soon. Here's a side-by-side which helps...

1. Thank you very much for the suggestion of going with a clamp's "circle pad" diameter of less than 30mm. 2. As to C-clamp twisting pressure required, I will use "paste squirting out the sides" as my best guide (because that is easy to see), with the pressure on my fingertips being the second...

No need to connect floppy drives or hard drives in order to get the Mac Plus power supply to work. However, I have never powered mine without ANYTHING connected (which is called a "no load" condition). I know that the SE & SE/30 PSU works fine with no load. Voltages are a tad different than...

@YMK Thank you for the photos and detailed info. Does "finger tight" mean "as far as it will turn when twisting with all your might" or "turn it just to the point when it gets a little hard to turn?" My heatsink arrived this evening, and my goodness it's quite heavy! Yes, it is very finely...

Hello, friends. @ScutBoy, on behalf of the TinkerDifferent Board, posted this info a few days ago about where donations can be sent to support this forum. There is no obligation to contribute, nor is there any kind of pay wall coming. Ko-fi is simply a convenient way for anyone to show love...

With it getting closer to the time my copper heatsink will arrive, I wanted to check with you about the amount of thermal paste and glue you used, and the precise means of clamping. Did you put a green-pea sized drop of paste in the very center of the CPU, then apply a half-pea size drop at...

My guess is that ticking is coming from the speaker, and desoldering one of the speaker wires would be a quick way to prove that. But even if you did prove that, the fundamental problem remains. What specific components on the board are resulting in the voltages going up and down like that?

He painstakingly did a lot of that work as mentioned in his opening post...

I believe so because he said the voltages are "oscillating randomly between 0.5 and 1 V on both the 5 and 12V line." But the question is, what specific component on the analog board is causing the voltages to become like that. I told @Michelangelo that I suspect it's a diode and/or transistor...
