Interesting - it's similar to my type 2 issue with dashes that build up in columns, but yours are squares and your columns are closer together. I can screenshot those too, but not the type 1 issue with horizontal tearing. Which version of PAL chips do you have at UE6 and UE7? Did you come up...

I've been posting extensively over on 68kmla.org but I wanted to ask here as well, since I know there are a quite a lot of compact Mac enthusiasts who don't frequent the other forum. I've been working to resolve an issue with my SE/30 Reloaded builds and it's become something of a serious...

I was just re-watching the excellent recapping guide by @JDW, on YouTube, for the SE & SE/30 analog board. On mine, C15 isn’t an electrolytic cap. Instead, it looks like this: Is it a film cap? It doesn’t need replacing, does it?

Nice work! How crucial is it to have? One of my SE/30s is missing its shield.

Sorry, reading your posts again I realise you’re not working on a new build board. Some of my advice is probably not relevant (the micro bridge thing in particular).

That shouldn’t happen, I’d try to find out what’s causing this before going further. The correct pattern is the one that appears at the end of the video. I’d suggest inspecting the VRAM chips that are adjacent as they might not be making a good connection. Putting pressure on the PAL could...

UK11 and UK12. There's two of them.

Did you see my edited comment above about the VIA chip?

So you've had the board a while, and it was working previously, and now all of a sudden it doesn't work properly?

Can you make a boot floppy on another Mac with MacTest Pro, and boot off that? I believe there are System 6 versions. Then run all the hardware tests and see if it comes back with anything. If you're convinced the problem is in the RTC area, I'd have a look at the VIA chip which is connected...

If it's not been recapped I'd suggest doing that first.

I've never (personally) seen an RTC chip fail in this way. Actually you can boot System 7.5 (or any system) without an RTC chip installed, you just won't be able to boot off a SCSI drive. You'll have to do more investigation before you can begin to make any conclusions about what's faulty. I...

In what sense does it fail to boot, and why would you suspect the RTC specifically? (As opposed to the numerous other things that could be wrong)

I’d try reflowing the Glue chip.

This is a great idea actually. This is likely a little over-cautious. Unless you have software you specifically want to run that's incompatible, you may as well just leave 32-bit mode enabled - and disable as necessary.

24-bit dirty software will crash if set to 32-bit mode, regardless of which OS you have booted. One example is Shufflepuck Café.

Hi! The firmware issue has to do with the Rev. C ROM card. It has nothing to do with the version of the logic board installed and you could fit a Rev. A or B ROM if that were a problem. I know that Sonnet has an incompatibility warning about using their Tempo Trio with a Rev. C ROM, but theirs...

Hi! I think @Bolle makes the adapter card for these.

Sorry for taking so long to follow up on my findings on this. I can now clarify what’s going on here. Basically, I can have just 4 sticks on 16MB installed when I’m using my Rominator II (which is basically a IIsi ROM with some extra features). With the stock ROM, it won’t boot: I need to have...

I’m not a cache card expert, but if you’ve recapped it and it still doesn’t work, it could indicate a failed SRAM chip - in which case the best thing to do is obtain another cache card. Have you made sure the card’s connector is clean, and the pins straight? Maybe you could spray some contact...
