Re: Argh! My new STE may have a DMA issue...

My first video doesn't help enough ? It shows that all parts have the jail bars problem, as well as the palette line trick not working. All tricks are working in the video you posted, although the Shifter-MMU desync shows jailbars. It does not show the vertical scroll you said flickered, which it s...

Re: Argh! My new STE may have a DMA issue...

ok here it is : VBL CYCLES : 160256 (160256 @ 8MHz) MFP_VBL clock : 8020854 MPFCALC clock : 8020854 TIME_LP clock : 8021082 Sound DMA : 50067 Thanks! :) Regular 8.02MHz STE. If the vertical scroll dude in Closure isn't working on that machine then it's indeed an unknown cause unfortunately. /Troed

Re: Argh! My new STE may have a DMA issue...

So the conclusion is that it's all in dlfsilvers head and it's a normal PAL STe? I don't know why he doesn't run hwtest004 which will show exact MHz, but since all Closure timing effects work (Shifter jail bars only affect display, not code path) then it's truly a standard STE. The vertical scroll ...

Re: STE BOOSTER V1 32MHZ & FAST-TOS

In terms of further testing, a diagnostic cartridge will bypass the TOS ROMS and allow you to see if the TOS ROMS are really at fault, or if there is a timing issue. This is what I thought as well, until I was reminded of (and verified) that the check for the diagnostic magic, and jump to cartridge...

1) This is a PAL STE machine How do you know? 2) IT HAS the problem you've specified above, i get jail bars on all the screens where the big letters move on the screen !!! Yeah, some do. It's a Shifter desync towards the other chips, not a speed difference. It's uncommon to go full jail bars on an ...

Re: STE BOOSTER V1 32MHZ & FAST-TOS

An Atari ST that shows a white screen and then either hangs or crashes has _usually_ issues with reading TOS content. But it's of course only one of many things to test. I'd do continuity checking from every CPU pin to some other point on the motherboard, esp. to the TOS chips. The u211 mod is stand...

I don't know what you mean with "reacts faster" but no, there's no real difference, otherwise all cycle exact demos would break.

Judging from all the commets and Willys info I could say anything above 66mhz should have a fan if you want to be on the safe side. Otherwise just a heatsink should be fine. You can always do any...

(A Pentium 100 or 80586DX4/100 also needed active cooling!) No, quite often not.

Easy explaining: Those 68060 are made for 50 or 66 Mhz, but we want to run them with about 100 Mhz. And this in the narow keyboard computer of Falcon that has no effective active cooling (the fan beneath of the keyboard is more or less a joke). No, it's not "easy explaining". If it was I ...

That depends on your fan ;)

(Also, I'm not sure why everybody mounts fans right from the start ... I'd start with a heatsink and then check the temperatures)
