Of course the drawback to this is if anyone posts any motherboard images where I would prefer a large resolution.. but the immediate issue is general uploaded images.

We'll just UUEncode them and post as regular text

I never thought about it with the floppy acting up... Can you format a floppy OK on it now then or does that act up still? I've had everything working nicely but currently (since trying to get the HDMI board in) the machine is in non-working condition :) Will get back to it at some point. I need to...

Don't know if it's related but on the doubleST I've had, several times, that "everything" seemed to work ok except floppy. So far it's been fixed by "luck" just shifting the clocks about a bit - which if I've understood your comments before mostly means I've skewed DTACK.

I was thinking of taking the internal scsi board out of my MSTE and putting it in my mega 4. Both have the same number of pins but there were some differences. I didn't really check into the differences but I'm assumming it would work. We all now what happens when I assume. Always get burned! The i...

Besides high contrast I'm not sure with what you mean by "blurred"?

Hmm, incidentally, Exxos are you running a stock power supply in your test machine? I have a stock PSU, I think Troed has a modern replacement. My 5v level is actually about 4.7v. Dunno if it could be connected but couldn't hurt to rule it out... My 520STM runs off a picoPSU and the 1040STFM off a ...

But so far, It seems like its only failing in stm machines?

520 STM and 1040 STFM (SMT rev) here. It's on my todo to run it on a 1040 STF (red led old model) and a few Mega STs. I'm really sorry for not being able to allocate more time to it atm ...

In any case, it is pretty clear that these ATF chips are working a lot better than the original GAL's I was using.

That in itself is a great finding that hopefully will benefit other hw builders for years to come.

(My 22V10 -10 at home are Lattice, I checked)

Also I don't know if it is about Mb revision yet. My Rev.B 520 ST has it in anycase. Do we know if the HDMI boards are ok? Somebody tested those non working boards on a different computer and then it run ok? No, that has not been tested. I'm the one first saw this issue, but on the 520 ST (C070243 ...

Maybe someone can loan Smonson a st with the issue ?

Shipping to Australia is crazy expensive. Also I don't know if it is about Mb revision yet. My Rev.B 520 ST has it in anycase.
