Re: Dead Exxos PSU out of the blue

I do have 1 spare board from the last production I did, I ran out of transformers so it never got finished. So what I will do is transplant the transformer from the power supply and fit it to the new board, then just send the newer board to Mikro.. Success at last. Sorry for the delay but it took s...

Re: Heatsink with integrated fan

Ingo, that's really a neat idea. I must measure the board but looks pretty promising, thanks!

Also thanks to everyone on the 'fan only' idea, obviously you know better so I'm going to follow your advice and avoid that kind of solution.

Re: GEM in 2018 ?

Running existing Atari ST SW: 1. GEM SW - should use Gemulator way: executing all VDI, AES calls not via emulation of 68K code and Atari display, but straight in X . That would give it extreme speed. And it will be needed for high resolutions, which are supported by GEM self, just need CPU power. G...

Re: Heatsink with integrated fan

Thank you guys for your input (on both topics). I'll post my results if/when I decide what to do. One small question - how good / bad idea is it to put a fan on the CPU without any heatsink? You see where this is coming from, I could remove the heatsink and replace it with fan, leading to better (?)...

Re: Falcon hardware on a ST.

I agree with others - there's really no point. Having the new ST with a 68030 + Falcon audio system and then ask for the DSP would make much more sense. I can't imagine one single (existing) application which could take advantage of it -- there's always something else missing to make it work (the 03...

Re: Heatsink with integrated fan

What's the size of the simm that can fit? I see some on Amazon, eBay and some Amiga places listed as low profile they seem to be around £30 We had been discussing it here: http://www.atari-forum.com/viewtopic.php?f=27&t=28770 ... typical low profile SIMMs >32 MB seem to be about 26mm what is too mu...

Re: Heatsink with integrated fan

Are you using the metal shielding still ? Assuming it fits over the. CT that is.. Nope, don't even have it for this Falcon. As I said, the biggest problem is the keyboard, the CT2 (in contrast to the CT60 for instance) has the CPU too close (mostly because it uses the original PSU so there wasn't m...

Re: Heatsink with integrated fan

Unfortunately, that size applies only to the fan (yes, a rather misleading title/description there). I want it for my Falcon's CT2 card, its heatsink is about 30x30x8mm (sitting on an 030) and I need to attach a fan to it. As you can imagine, the biggest enemy is the height, it must fit below 15mm a...

Heatsink with integrated fan

Hi guys, have you ever seen a heatsink like this one: https://www.ebay.com/itm/Aluminum-Heatsink-with-fan-for-5W-10W-High-Power-LED-Cooling-Cooler-DC12V-FLHXN-/323371063969 but smaller (say 40x40mm, ideally less). There's like a million of fans and coolers all over the net but I'm failing to identif...
