Something about catching Pokemons, and all of them... 😅 I was told full 68060 Rev.6 CPU prices are high, because they are extremely scarce. I don't know, they seem quite abundant to me. 🤪 👍

@chainq that heatsink on the ACA accelerator is just perfection!
Show threadCharlie BaloghMar 1, 2025
@polpo Yeah, that's definitely well made. I'd also buy that for my TF1260 if it was available separately. (Too bad the TF1260 has no mounting holes for it, or for any for that matter.)

@chainq the 060 I use on my TF1260 came with an epoxied-on heatsink, so I had to shave it down to fit under the keyboard. That solved the mounting problem, at least

@chainq and here’s how I get some airflow over it: a 40mm fan stuck to the floppy drive with foam tape

@polpo This is in concept very similar to how the Warp1260 cooling works. That has a radial fan, that sits on the floppy and keyboard LED pins for power and mounting. Then it blows over a wedge-shaped heatsink, but it is wider than yours though.

Note that the ACA1260 has the CPU on the other side (towards the drapdoor, like the Blizzards). And I think it wasn't designed to run with a closed the trapdoor. I'll post about it later.

@chainq @polpo the idea is to leave the trapdoor cover off and add extra bumpons on top of the previous ones on the bottom of the case to improve airflow.

@polpo Not sure I ever posted the Amiga 1200 w/ Warp1260 guts on Mastodon, so anyway, here's how it looks.

The fan is temperature/software controlled. I'd buy such a generic cooling solution for almost all my A1200 expansions. Even the 68030 cards tend to run quite hot, especially with FPU & SCSI module, and they're not getting younger either...

Note mine is an early card, so hopefully they improved the powder coating of the heatsink since. 😅

@polpo @chainq so far I've been running my TF1260 without any heatsink or fan. I have one of those 3D printed trapdoor replacements with a grille, which helps a bit but I don't dare running it faster than the default 50Mhz (not that I need more speed). I'm quite sure my ‘060 is one of the lucky ones that don't get too hot. It could use a thin heatsink at some point anyway to run a bit more chill.

@aperezdc @polpo 50Mhz usually works without a heatsink even. It has always worked. Also on older cards like Blizzards. Although I've seen stock 50Mhz cards, - Blizzards at least - overheat on very hot Summer days with the trapdoor on. But that could be also memory and other things, not the '060 itself.
