I'm still hoping and praying that @MacEffects can one day clone them for us. Until then, I sadly have no technical specs to provide and don't think cloning one will be possible. Most people ask about outrageously priced flyback on EBAY which are not running $145 or higher. And to think, those...

Can't believe it. Just got home from work and was able to test my Mystic when I realized that I forgot to flip off the power SW at back last night. The power was on all day in my room at home with no A/C in the heat of summer, and that means the ambient room temperature was probably 35°C or...

I'm still concerned about the 133.9°C max. temperature I measured on the 1N5355B 18V 5W Zener diode (DO-15 package size) soldered to DL22 pads. It stays that way for about a half hour after you do a Shutdown from the booted condition and then it remains at about 121°C to 125°C (well, at least...

@iantm I tagged Ron in hope's he'd provide details, but since he hasn't I can only tell you what I know, which is limited because I have a different adapter and not Ron & Joe's. You can find Ron's video adapter creations on Joe's website here...

It would be quite nice if a simple ROM flash could switch resolutions because it's easier to pull the motherboard out for a ROM flash than it is to pull the Analog Board. But alas, resolution changing is hardwired to those silly Analog Board SENSE LINES. 😕 And very sadly, on top of that, the...

@Ron's Computer Videos "running a display" on... the SE? SE/30? Internal, or external?

No because the PDS slot in the SE is not the same as the SE/30, and the 30Video PDS card is made for the SE/30.

Ken, I just finished watching your video and I must say, you have a truly brilliant mind. Absolutely ingenious! @frontein1 and @David Cook , you two gentlemen might find this work intriguing as well! Note that the SNOW emulator mention is found here: https://snowemu.com/

Use of VPNs and Relays impacts other popular Mac sites like Macintouch too. Do a keyword search for "iCloud Private Relay" at the following URL: https://www.macintouch.com/macintouch-faq/ I am not saying anything negative against VPNs and Relays. I honestly think they are important. I am...

Now that I've done the 84V Mod, I can answer my own question. I only did a single test with the IIe Card installed on the stock CC motherboard, and the Mac's resolution is now 640x480 with the 84V mod. But for reasons unknown, the left/right black borders are thicker than when I have the LC520...

@frontein1 I have two questions: QUESTION #1 Mustermann's thread on the MLA says he wanted to DISABLE the soldered 4MB of motherboard RAM. Your previous message says the "About..." dialog on your machine now shows only 128MB instead of 132MB, which indicates your v092 file does indeed make the...

MYSTIC UPGRADE: Hacks/Mods Clarified Today, a viewer of my 475 Overclock video said he has an LC575 board in his Color Classic without the VGA mod and is using the ResEdit hack (see 2.1.3 here) to "change the machine ID." He also said he was running System 7.5.5 but was having issues with...

Thank you very much for testing and reporting back! So, we now have 2 people thus far with the stock resolution and with a TechStep replica cartridge Vol.4 (whether a removal one or one inside the memory of the Replica TechStep shouldn’t matter), and both gentlemen can diagnose the stock CC MB...

By the way, this is a teensy tiny bit off-topic, but since I started this thread it's no big deal... I never liked the look of the Color Classic back in the day, and it wasn't only me. The April 1993 issue of Macworld had this to say... But like Tim Warner said in the end, I found that...

I wrote this in my earlier post... since the ports on the stock CC M.B. and the 520 board are the same Meaning, two ADB ports, in comparison to the LC575 board which has only one. I was using the term "the same" only to refer to the ports being similar. Indeed, and we see that in the April...

But here's the thing. I have two Serial Loopback Plugs, and Snooper 2.0 completes testing of the serial ports multiple times without error: I tested that just now with the stock CC motherboard and of course 640x480 resolution via the 84v screen mod.

Thank you for very much testing and replying back. I really appreciate it! I'm overjoyed, in fact! I wired everything in the same way I wired the LC520 motherboard, which is meaningful since the ports on the stock CC M.B. and the 520 board are the same, yet the 520 worked with the TechStep's...

Very glad to hear my review helped you. I should mention that CayMac Vintage web store is down until Sept. 10th (2025), and sadly, the way Ko-Fi works is that web pages seem to go offline when the store is down. But Will Jacobs told me he would be back in Cayman on Sept. 10th and the store...

I'm pretty much never on Discord. I don't hate it, and I like it's there for folks who enjoy it. It just doesn't suit me. Believe me, I've tried. Yes, I did start out in real forums like this one so there is a little bias, I guess, but I find that "Discord" is truly that. A bit more strife...

Asking questions in this forum can be good because a lot of people don't make time to post anything once they've solved their own questions. The ends result is all that research and effort only benefits them. By asking questions, the exploration is made available to everyone. A lot of folks...
