Sorry for my delayed reply. I've been dealing with a family medical emergency since the 21st, and it is still ongoing. I've not tested this, but what happens if you install Wish I Were and set it to a Mac which supports that expanded Monitors & Sound control panel?

I have been referencing that Stuart Bell / Alexey Danilchenko guide, which you can find still online (in addition to Archive.org) here: https://www.applefritter.com/powercolorclassic/stuartbell/compends As always, the processes we find online are short on details (e.g., what is CS2? CS6?)...

How many seconds does it take before you see something on the CRT after pressing the power key on the keyboard?

No doubt Kai is a Back to the Future fan too, but I suspect he has a lot on his plate right now, which is why I didn't want to double-dog dare him myself. Goodness knows that I am so busy I could scream! Even so, it might be good to check the interest among people the vintage Mac and Apple...

The stereo mode involves much, much more than just adding another speaker. It will take a long time for me to explain the procedure properly which is why I want to make a video on it. I simply thought you had found a place on the Internet that described all the parts that you need. there’s...

Thank you, Stephen! That datasheet covers the 128MB VRAM stick owned by Kay Koba. Checking the IC p/n on the 64MB VRAM sticks linked in my opening post (as per the photos on EBAY), I see they too are 3.3V! https://www.datasheets360.com/pdf/-2025349853503483442 So it's rather clear that 3.3V...

So you put one 10kΩ resistor from the RED wire (Right) in your picture above to the BLK (GND), and then put another 10kΩ resistor from the WHT (Left) wire to BLK (GND), correct? And previously, you had the two 10kΩ resistors inline with each of the RED & WHT wires (i.e., not going to GND), correct?

So based on the RAM that Kay Koba and Mr. F. have, it would seem that PARITY doesn't matter, and RAM with 7 or 8 or more chips doesn't matter either. Although we've not gotten too specific about what vintage Macs all of this RAM works in, except that Kay's RAM does indeed work in the LC575...

Those chips are owned by @Kay K.M.Mods . Maybe when he has time he can tell us how hot they get when overclocked. That might tell us a lot about the printed numbers being real or fake.

If one of you could sketch out a simple wiring diagram for the connections, including the resistors, that might help others who are following this thread with interest. No rush. Just whenever you have time.

These are the markings on the LC040 that came with the LC575 in untouched condition which I purchased on Yahoo Auctions Japan at the end of 2021... TOP LEFT SIDE Those markings are originals make by Motorola and do not come off even after repeated application and removal of thermal tape...

If someone recreated the equivalent of the IIe card in the form of a rPi that connects to a CC or Mystic MB via PDS, the end result would be the same, and I would not have any issue with that at all.

@Kay K.M.Mods showed me the photo below in the past, which means he got that particular model number to work fine in his Mystic. That implies the 64MB modules I link in my opening post should also work, but I'm still unclear on the voltage. I doubt that his 128MB module is 5v and the 64MB...

You know, I don't own a single Apple II device, but I am getting this burning desire for an Apple IIe card for my Color Classic. I really would love to do a video on that. I am not, of course, willing to spend $700 on one, which seems to be the going price. With all the SE and SE/30 Reloaded...

Thank you for the replies! The still unanswered question about the 2 types of Keystron RAM I linked in my opening post is this: Are those Keystron 64MB SIMMs 5v or 3v? If 3v, I assume they won't work in an LC575 MB. Are your working EDO SIMMs 5v, @Mr. Fahrenheit ?

Craig, perhaps @Kay K.M.Mods can comment, but since I do not have a IIe or RaSCSI, I really cannot answer your question.

Recommending FPM RAM is best, I agree, but in terms of newly made RAM that is easy to find and buy at a reasonable price (i.e., not older RAM sold at auction), the Keystron brand is about the only thing I can find. The issue thought is that it is all EDO, not FPM. Here's a link to all the...

I appreciate this thread very much. My plan is to do a video on MacSD in a Color Classic, and also a video on the Stereo Mod, which concludes taking the speaker from a junked Quadra 630 and using it inside the Color Classic. But I must do my overclocking and Kai Robinson SE Reloaded videos...

Thank you very much for your reply! I Googled your part number but that 128MB stick appears no longer sold. The 4 reasons why I am desperately seeking first-hand experiences with the specific RAM linked in my opening post (RAM that is currently sold) is the following: EDO RAM is not 100% the...

I posted this question on FaceBook (Vintage Apple Macintosh Enthusiasts group) 5 days ago and not a single person replied, so let's see if the amazingly knowledgable folks here at TinkerDifferent can do better! Do any of you have experience using any of the following Keystron RAM SIMMs in your...
