Both of our video cards are pretty much compatible with every accelerator that you can throw into a SE/30 in one way or another. My grayscale card is working fine when combined with PowerCache (socketed and universal), Diimo, Turbo040 or Carrera040 - vintage or cloned cards. The same is true for...

That's right, currently I can't ship anything other than the US using standard postal service. As a private individual the only acceptable way to send something to the US currently is using DHL Express (at an added cost compared to standard postal service) DHL Express is going to clear any items...

I can see a Daystar adapter peeking out below your Carrera040 there. Interesting to see it's running at all. The jailbar view is as far as you'll get. The patches SE/30 control panel is not going to do anything different as the bars you're seeing are caused by a hardware issue of the Carrera...

@zigzagjoe made one that stands up and has a PDS passthrough.

Looks like those have a 500mil spacing between both rows. The sockets that were originally used have 400mil spacing. There's not going to be enough space to fit those I'm afraid. But it looks like there are also dual row sockets with tighter 300mil spacing. Those could be made to fit additional...

I don't think a 33MHz GAL based model exists. With the speedbump they also redesigned the whole thing and funneled all the logic into those two gate arrays.

Exact value doesn't matter on those. If I remember right the JLCPCB BOM lists whatever part was in stock (and a basic part whenever possible) at the time the file was made. It might be a good idea look at JLCs stock and compare if there's another option right now (as in cheaper, in stock...

There are no video signals present on the edge connector. It's only three VIA pins (one of them used to put the machine into test mode) and one of the serial ports (for the test equipment to communicate with the board). Also obviously power/ground as you already figured out.

Looking through my mouser history it seems I have ordered 38-HX5F12.5-32.768KHz before and they again seem to be fine as drop in replacements.

I have used these before as drop in replacements: ABLS-16.9344MHZ-B4-T The load capacitance doesn't match the original either but it has always worked fine for me so far (on both original logicboards that needed the crystal replaced because it got eaten by cap fluid, or when building SE/30 and...

On a reloaded board you can just go for ISSI IS61C256AL in SOJ-28 which is still in production. I made the pads for the SRAM large enough to take both, SOJ and the original wide SO footprint.

Still depends on the machine and upgrade type, they're not all the same. On the one shown above it's obvious as the original CPU comes out for the upgrade to drop in. Some machines that use adapters that go into the CPU socket and present a IIci style slot for an accelerator move the logicboard...

Ha, alright. I wondered if the word on the JLC blooper already was spread or not because I didn't find anything in one of the group buy threads yet. Good to know everyone is informed already(y) I'm still kind of curious if it's all boards that they messed up.

Check if you've got BAS40-04 instead of BAS40-06 diodes installed on the bottom of the board for D4 to D19.

Those stripes are the default contents of the VRAM. (depending on the vendor of the VRAM the default contents can also be thick horizontal stripes - yours are the thin variant - or gray background with vertical lines of garbage that are 1 pixel in width) What that means is that the board didn't...
