Just throwing this out there , would you not have the soldering along side the sanding and a common extraction / filter setup ?

Nice idea. Yea, I have a list of updates, and that shouldn't be a problem. A dropdown in preferences to pick weather or click on weather to cycle it to next one.

Give github.com/retrotheory/... BigMaclock a try, It supports dynamic pixel sizing so you can run it on a larger screen. #MARCHintosh

Use the "SetClock" Utility from Macintosh Garden, or use year offset to fix incorrect DAY , 1998 seems to work for this.

Instead of turning a clock into a vintage Mac, I turned a vintage Mac into a clock!, I though it would be fun given its #MARCHintosh The program can be downloaded here: github.com/retrotheory/...

It supports US/EU month day order AM/PM, Invert display, 'grey' background and alarm function

A vintage Macintosh Plus and a Macintosh SE/30 computer sit side-by-side on a desk, powered on and glowing under vibrant pink and blue "vaporwave" neon lighting. The Macintosh Plus is in the foreground, displaying the "About This Macintosh" system window on its monochrome screen, with a classic mechanical keyboard and mouse positioned in front. The background is a soft, out-of-focus wash of neon colors against a plain wall.

At 40 years old, this Macintosh Plus is officially living its best life: no social media, no notifications, and zero concept of "The Cloud"β€”just a physical box of floppies and dreams

Are your jumpers set for CGA ? If 5 and 6 are both off then motherboard is set to MDA

We had a power brown out, and it just scrambled the display. The powercycle fixed it.

Picked up an old soldering station from a junk yard in Mos Eisley, seems to be stuck in Aurebesh mode.

It was shipped with a keyboard in the same box. The monitor was just sitting on the keyboard. During shipping, the monitor had no chance as the uneven base resulted in cracks, and then the rest of the damage occurred.

Yes indeed, and hope the battery has not exploded, as they tend to do.
