@Drake , where are those battery mods sold? And if not sold, do you have a photo of the battery side? I'm curious as to what battery you are using. You see, the stock battery is 800mAh. I measured current consumption on the LC575 MB (disconnected) with a 4.5V power supply attached and found...

The reason I don't whip out an alternative Mac from my closet is I live in Japan and lack the space for the expansive vintage Mac collections of my peers. (Yes, I do get rather envious of you folks at times.) When one has few options for vintage Mac color, one tries to maximize the option he...

I believe that modding the LC575's MB in that way would indeed cause issues when placed back in the LC575 chassis, but I have not actually done that to verify my assumption. Honestly, I'd rather not mod my 575 motherboard. I prefer to do the Analog Board mod instead to get 640x480.

My video on this LC575 MB swap process will be out within a few days. The 065 v1.1 enabler is only required for System 7.1. The fiddly ResEdit hack is for System 7.5.5 (no enabler required), but I did not do that because I have other things I need to do in this CC video series. My CC will...

A hissing capacitor sounds quite interesting indeed. 🐍 Would you mind shooting a short video of that cap (with audio) for us? Obviously, it needs to be replaced along with the other analog board electrolytic capacitors, but I am curious about which capacitor is hissing, as well as the precise...

Thank you for the kind offer. My 3rd installment in the Color Classic video series will be on the recapping of the LC575 Mystic motherboard, since my stock Color Classic board has already been recapped. And while that may disappoint some, please know that stock 68030 board is painfully slow...

Even more consistent than exploding though is the melting of the base. With hot air, you're melting the poor guy's fanny! 🥵

Fascinating... and thank you! I am now envisioning a "Play-Doh & Hot Air" special on YouTube! :) Should I ever do that video, you will of course receive the credit, @trag!

I see the twisting in that video but not the pushing! :unsure: :) Even so, I'm partial to my Hakko hot tweezers. They aren't for everybody due to price, but I've yet to lift a pad by accident with them.

I would recommend MacBench 3.0 (when it works) because you can then run it on an SE/30 too. If you go with MacBench 4.0, you can't use it on the SE/30. Maybe that doesn't matter to you, but that's my personal rule of thumb. Admittedly, I don't use OS 8 on my vintage 68K Macs, opting for...

If you need a soldering "iron" hotter than 350°C, then something is probably wrong. It's too easy to overheat sensitive components when you go to 400°C with an iron (especially solid Tantalum capacitors). Some people do it and have no issues, but 350°C is a good rule of thumb to stick to. I...

Of course. Just not necessarily preserved by me. I shall leave that task of saving expensive Lisa’s to you fine gentlemen! As for that beautiful Quadra 840AV though, I truly look forward to preserving one of those awesome Macs one day.

I've never really understood what all the fuss is about when it comes to the Lisa (noting the one in the background above), mainly because it isn't such a practical machine. I do remember seeing one new on display in the computer store when my Dad and I went to pick up our brand new 128K...

Yes, the 3 wires on that schematic marked SV0, SV1 & SV2. However, I myself have never checked the voltages on those wires, so I do not know what the normal level should be according to the Control Panel volume setting. I guess you should check to see if the voltage levels change when you...

Attila, Connect headphones, then try changing the volume and report back if the volume is still the same at 1~7 or if it changes.

You will need to start checking voltages with a digital multi-meter on the audio circuitry to see which components could be bad or which traces may be severed. I will send you a PM with high quality schematic for the 128K motherboard.

The red substance under the anode cap that is applied directly to the CRT is not glossy, but it is "hard" (i.e., not soft or rubbery to the touch). Even so, I've not found a replacement that perfectly matches the original red stuff.

Absolutely!

Backlit Macintosh Portable (because despite it's size, it's a rather attractive looking machine, and the first flat-panel portable Mac from Apple). Quadra 840AV (because it's the fastest 68k Mac) Neither are rare. I've just never gotten around to paying the prices demanded for those machines...
