So, the only thing I hate more than people forcing me to published unfinished work because they are redoing what I spend nights already doing, is people wasting time doing what I already did…

Another week later to get the 45° filter variant. Since I could only find (reasonably priced) adhesive variants shipped to where I live, I thought I'd try to see if I could actually get it to stick reasonably well. However, as mentioned before, I totally lack the skills (and tools!) to do this reasonably well, so the result was.. abysmal. So many bubbles! Who needs Marine Aquarium when you've got me slapping on this bad boy. Yikes.

With that success under my belt, I felt hopeful. The next step was to find out the polarizing filter's orientation, as that varies by display. I wasn't able to find this online for this specific model, so I thought I'll just order a few in the obvious orientation choices. Easy.
I initially didn't order the 45 degrees variant, because I thought; surely it's not 45 degrees, right? That'd be a silly number.
Right?
It was 45 degrees.

But I digress.. the residue has to go, and no amount of alcohol was doing anything to it. I found this recommendation for a certain cleaning liquid designed for this very purpose, so I ordered that and gave it a try. To my surprise, it worked amazingly well.
I put two paper towels on the display, drenched these in the liquid, let it sit for a bit, and then wiped everything off. That's it, super simple. The screen looks gorgeous!

And the smell! Don't get me started on the smell. I did this in front of an open window wearing a mask, but still had to walk away. Just the act of removing the film awakened this positively vile chemical stench that just can't be right.
Kind of terrifying we're normally sitting in front of this (while warm from being powered on!). I wonder if this stuff slowly seeps out too over the years? Yikes.

I mention scary because have you ever tried to apply a screen protector to a phone display? Yeah, well, I suck at that. This would be that, but bigger *and* required removing the old polarizing filter without, you know, destroying the display in the process. I know what I'm doing, I lie to myself.
Anywho, in for a penny.. Fortunately the filter came off fairly easily. But by golly did it leave a *ton* of glue residue behind. Hoboy.

PowerBook 145B!
Station Villa-Maria, Métro de Montréal

Wait a minute. ENHANCE. The top of the screen says PowerPC and the label says 190cs, and the motherboard has the 040 board. So it’s a PowerBook 5300 screen with the PowerBook 190cs stickers. Someone was birthing their own frankenMac. Flip, if this is the TFT version of the LCD, I’m going to run around my garden like a mad man! #frankenMac #powerbook #retrocomputing

@ActionRetro Right now, I can't even get my #PowerBook G4 400 MHz #Mercury to start, even though it worked when I just bought it. I had it in storage for a couple months and decided to play with it again. Have done the usual, reset #PMU removed battery, let charge overnight. I'm planning to sell all my #PowerPC Apple laptops I have accumulated over the years because I sense they don't have much longer live.
