Niiiiiice

Super quick update, I popped the original Shifter back in and re-ran the quick blitter test from the diag cartridge and it passed OK.

Yeah these machines are like trying to keep an old Ford Escort on the road. You never know what part is going to break every time you turn over the key.

You're not wrong!

Just to confirm have tried the same on the ST Remake as this is the only one I have a blitter in.

Without vsync and blitter enabled I can not reproduce your behaviour RJ. The boards are working ok.

All the more reason for me to try some other boards I think.

The scope is just to load pins.. You could (and probably better) use a small pF cap, something like 47pF on a fly lead with one end soldered to 0V. Then just go over each pin on the shifter one by one, and see if the video improves (becomes more stable when the 47pF is on any particular pin). The s...

The good news is the ATF chips come.. the bad news is they were ordered before the latest firmware changes, so the firmware no longer fits in a ATF1504 :( I've been trying to compile it in a 1504 and it just won't do it :(. The code isn't that complex even, so its mad it won't compile. So I will ha...

I'm a visual person, so the video was the best way for me to show you all what I meant. As for the socket, it is not turned pin, but a cheap one which was already fitted to the board when I got it, and I don't think I have a machined one spare. In fact I think my machines that do have a socketed shi...

I was going to suggest trying the remake board :lol: Can't do that until I finish the board :( In the meantime I will try some other STFMs, provided I can find one or two with the Shifter that is socketed. I'll also try with the vsync connected. Which pin of the Glue does this need to be connected ...

So in answer to the questions you've raised: 1. Unless moving the mouse to a certain spot causes the ST or its associated wires to move. Question: does it still happen when you use the keyboard to move the pointer with ALT+arrows? The ST doesn't move when I'm moving the mouse pointer, the only cable...

Ok, so I quickly ran some tests in low/med/hi res on a 1040STFM running TOS 1.02 (I may have mistakenly said 1.04 earlier) including Blitter, with the DVI board set to jumper B and no vsync cable, and the outcome was as follows: 1. Throughout the tests, even when the screen was blank, the LED on the...
