No rush. I have the 8" version on the way. Although this would allow me to set up one on my IIc and one on my IIc+. It looks like I have the iPad 1 version, but feel free to work on them in any order that makes the most sense for you.

I think @phunguss' images were of his iPad screen and display controller board. That matches what I have been using with my Apple II (driven off the display out port to pass composite video and 12v to power it. I don't believe those pictures are of the 8"display (it's too wide), but it does...

I actually watched this video and it seems like the resin prints may be ok with just screwing directly into the part. But that may not work with the current models as the holes were setup to accept inserts, not the screws themselves. I'll let you know when they arrive how it work. Hopefully I...

OK, I was able to pull the 33MHz full 040 from the bombed Quadra 800 I had and swapped out the resistor, and the clock from the Q800 board and I got it to run at 33MHz and identify as a Quadra 800 when I use the LED with jumper from the Q800. The 800 case, as you saw, had seen better days. Any...

Hey, I haven't forgot about you. I have the adapter I just haven't gotten around to finding a box and getting a shipping quote. I will try to get one in the next day. Still wasn't able to get them to work - hopefully you'll be able to get it to work. Also, you'll need a decent 24V power...

RESOLVED!!! @joevt and @iigs123, thanks so much for all your help! I was poking around all the pins that should have the BDb29 data line and noticed something odd. Pin 1 of RP6, which has BDb29 was somehow shorted to pin 16. Looking at the schematic, that shouldn't be because pin 16 is the...

Looking at the image in Basilisk II, the black line repeats at pixel 2 (with the far left pixel starting at 0), then repeats every 32 pixels (e.g. 34, 64, 98, etc). Here's the image (I made cascading pixels where each vertical line is 10 pixels) How do the vertical lines translate to the...

Good point. I forgot you had brass inserts. I may need to do a bit of drilling and glueing. I'll let you know how I get it put together. It may be a few weeks. JLC3DP usually takes 2-3 weeks to get here with the cheap shipping option.

Given that the corruption shows up in my screenshot, would the data lines be D[31:0], or are you talking about the PD[31:0]?

OK, so I did some probing with the Q800 schematics and checked some additional things. I have been focused on anything related to D28/D29. For PDf[28] and PDf[29] and PD[28] and PD[29]: Starting at U8, the connection from 60 and 56 to RC4 15 and 19 are good. The resistance across RC4 pins...

Ok, having the schematics for the actual wombat board should help me. I was trying to make educated guesses translating from the LC475 schematics and I don’t think I was making the right assumptions. I’ll take a look at this one.

I didn’t think about doing screenshot. I assumed it was something on the output side. Since the lines show up in the screenshot, this means it’s between the CPU and the vram (or the vram itself)? Also, after checking some of the traces last night and not finding anything, I started to suspect...

I traced the PD[28] and PD[29] to the VRAM. all looks good - it does have a resistor inline, but that also seems ok. @joevt is D29 / D28 different than the PD28 and PD29 I looked at?

Ok, as I was looking at the traces in that area, I realized there was another chip that wasn’t populated on the board, U3, right by the video output. I was hoping that was the cause of the problem. I grabbed it off of my spare board and started it up again but the video was still bad, although...

It was set to 256 colors. I did change it to thousands of colors and to grayscale to see it if got better, but it didn’t seem to. I didn’t think to change it to B&W, but I’ll do that tonight and see how it looks.
