Thank you for making time to test, photograph and post such a detailed reply. I sincerely appreciate your time, @Daniel Hansen . Tremendously helpful! My comments... 1. The shape and overall look of on-screen text I see when viewing the output of my IIc on the EYOYO display has never been...

No…

Dealing with Mouser’s incessant changes is a full time job, so because they are still in stock I’m not going to waste time swapping them out for now. There are always replacements, so I’m not worried, but sometimes the only replacements available have slightly inferior specs (often ESR). So...

Spotted this today: https://www.1bitrainbow.com/parts-store.php?products_id=4428 NOTE: the URL above sometimes opens a page with a search field, for reasons I don’t understand. If you get a search page, just type in “pico“ and do a search and you’ll find the product in the results...

The question asked in my previous post still stands, but I did a little more digging and found the following 2 points to ponder: 1. The video by RetroRGB (Robert "Bob" Neil) oddly does NOT link to the same ESP2866 board shown in his video — the Weymos D1 Mini. Instead, it links to the this...

Thank you for your kindness in answering my questions. The GBS-8200 board, which in my case is currently stock (no ESP8266 installed yet), is outputting 1024x768 by VGA and the EYOYO monitor is confirming such. Meaning, the EYOYO is confirming its in its native resolution. However, there is...

Yes. But as shown in my Big Copper Heatsink video, if the heatsink bottom and 040 top aren’t perfectly flat, it is possible that the tape made not make uniform contact across the entire top of the CPU. Which means heat would only be transferred to the heatsink at points of tape contact. The...

Again, I am no expert on these SWIM chips, nor do I have experience toying with them as you are. But any signal-level pins like RESET, DEV or even Address lines shouldn't be requiring a lot of current, so using pull-up or even pull-down resistors should be very safe and achieve your aims too...

Well, for important matters like this, I myself wouldn't trust ChatGPT, and I see you aren't either, which is good. We must also try to never "assume" either, which of course is why you are speaking to me in this thread. Well, the only thing I can do is what you can do — find pinouts and...

Thanks again, Colin. For all of you reading this thread, the screw and washer links are here: SCREW (100pcs): https://www.mcmaster.com/catalog/131/3424/92525A205 WASHER (100pcs): https://www.mcmaster.com/catalog/131/3700/95060A320 Merchandise Sub-Total: $8.57 You then must fill out address...

That's neat because when I use my Micron Xceed MacroColor 30HR video card with an external display, the internal 9" CRT can't display anything, as shown below...

@Daniel Hansen I've got some questions for you at the bottom of my post, but please allow me to first explain my situation... I've grown weary of display issues pertaining to my Apple IIc and my Eyoyo 10" IPS SVGA (1024x768 native) Display. The monitor is a wonderful size and is all black...

ANSWER: Yes! My thread about Heatsinking the 040 is here: https://tinkerdifferent.com/threads/68040-cpu-heatsink-clip-for-color-classic-mystic-lc575-motherboard.4349/ And to supplement that thread, please note that I made two videos about heatsinking an 040 on the LC575 below, and those were...

The -8 at the end shows they are the slow 80ns type, which is typical for stock VRAM in the LC575. To get the most out of either Kay Koba's Spicy O'Clock or 475 OverClock, you need faster VRAM. Yes, there are the lazy folk who make due with slower overclocks because they don't want to buy...

@This Does Not Compute Wow! Your compiled info is what everyone needs to know! Thank you! More specifically, you name the Analog Board to Chassis screws as being MCMASTER 92525A205, which I Googled here: https://www.fastenersuperstore.com/products/299084/self-tapping-screws Pricing of more...

Your pin numbering is correct for UJ11. But you are saying that UJ11 pins 20, 21 and 38 need to be pulled-up to 5v via 10kΩ resistor. How did you determine that? Because on the schematic, I see pin 21 is tied to pin 24, and that is labeled READ DATA, shown to be an output according to the...

Does that mean you've never purchased the screws used to affix the SE Analog Board to the metal chassis? No doubt there must be at least one person out there who has, and I'm just curious if they went with an M3 shaft width, and then would like to know which kind of threads (as per what is...

Tagging @David Cook , as he might find this dialog interesting. (I myself found it interesting because the same person is both asking and answering!)

@Mac84 It's now just over 2 years since your last post in this thread. Did you ever get your card to work?

Yesterday, a viewer of my Macintosh SE & SE/30 Analog Board Recapping Walkthrough video asked me about SCREWS which affix the SE or SE/30 Analog Board to the metal chassis. It was a good question because I too have some missing. Here is a photo of the TWO TYPES which I have seen over the...
