Here is the diagram I made for the HJ080IA-01E panel. The black area is the compact Mac's physical screen opening. The purple box is the panel's physical size. The blue box is the panel's display area. The green/white box is the physical size of the panel's display area when letterboxed to a...

I did a bunch of panel shopping last year and decided HJ080IA-01E to be the best option for physical size, resolution, availability, etc. I was planning to make an lvds driver circuit for it but haven't yet. It would be perfectly fine paired with an hdmi driver board and rgb2hdmi as well.

You can also power it with micro-usb.

Yeah, that's definitely a big relief that it was a simple thing. Those scares are not at all fun.

Fizzbinn, thanks for doing this experiment. Very neat tidbit to discover. Someday I'll get my IIvx working and it can join the HD20 club!

Oh boy! Twitter caption: "Documentation is merely a suggestion "

The suspense!

Ahh, I got floppy connector vs swim pinout mixed up. Also forgot PLCCs have an obnoxious numbering scheme. Good thing you're prepared!!

Tell me if I'm wrong, but from here that looks like pin 13, not pin 14. Very nice soldering job!

Hey, I tried clipping onto my IIvx's egret pin 14 instead of the SWIM (facepalm). I had spent a lot of time cleaning corrosion off the egret and just had it stuck in my head. The clip broke the weakened leg off (double facepalm). So, uh, be careful not to short or break anything. It does seem...

Are you running without VRAM? Is that the issue?

At this stage it may not be productive or economical to spend more money on this bluescsi. Consider ordering a pre-assembled one instead of a kit, or one of the other scsi drive replacements which come already assembled.

There are several issues with this assembly. As @Daniël points out, that SD card slot is probably shorting scsi termination power. Every time you turn this on you're testing the machine's scsi fuse. (Not a good thing.)

I started working on an HDD noise simulator a few years ago. It was perhaps overambitious relative to my actual interest, as I was intending to characterize the sound of various classic drives, produce noises based on distance the head had to move and read/write block size, etc. At this point it...
