Re: What on earth is this?

Lesson learned. I just wish it wasn't exactly this way but could have been worse.

Re: What on earth is this?

Perhaps I should have specified that this happened out of the blue, i.e. the PCB had nothing even remotely similar there before. I simply started desoldering and it appeared like a plague. :) Bad news - the pad is indeed gone. Good news - fortunately that pin is not connected. Still, never seen anyt...

What on earth is this?

So I recapped the TT PSU, was waiting only for PC111 opto to make the job complete. Arrived today, so hooray to desolder the old one... I swear to all Gods of Electronics, I didn't do anything else than hot-aired the PCB: IMG_20181115_143749.jpg It can't be scrubbed off by isoprohyl alcohol, it seem...

Re: Sad day: I'm having to "upgrade" from MiNT 1.12...

Do you know if the compiler tool chain etc. will run under MiNT natively? i.e. Can you develop on the real hardware still? Absolutely. gcc 7.x is quite slower than the ancient 2.95 but it does work. I know the few people who are keeping Linux m68k seem to be cross-compiling and then running on emul...

You are right - I wasn't there. Actually I'm still not there ;), I'm just helping guys with some infrastructure. If you would like to discuss ideas / features, maybe it's worth signing up in the new ML: https://sourceforge.net/p/freemint/mailman/freemint-discuss/ There isn't many people left and any...

Re: Sad day: I'm having to "upgrade" from MiNT 1.12...

Once I got my TT operational again I even asked if they needed any help and was rebuffed (in a sneering manner) as they were only interested in XaAES integration at the time and weren't interested in the multi-user side of MiNT at all. It was clear that they were an inward looking group who didn't ...

Re: Sad day: I'm having to "upgrade" from MiNT 1.12...

started removing parts of the system they didn't understand, such as the nascent share library and virtual memory code. The memory protection system has languished too. "Recently" they removed the virtual console code as the developer thought it wasn't useful. Neither of these sentences are true. Y...

It does mean that everyone might be running these fans "backwards". I need to look at how I connected mine.
I've been wondering about the same. So what is the original direction? Is the fan sucking new air in or blowing hot air out?

Re: MSTE PSU has 25V cap instead of 10V - safe to replace?

I do try to list caps in my store which reflect what's in the actual kit, though things can change batch to batch so looks like I just didn't list the caps in that kit at all due to the constant changes of parts. This is totally OK. I was just wondering what was the reason and if this is the reason...

Re: MSTE PSU has 25V cap instead of 10V - safe to replace?

Actually, I have a real report similar to this one. :) Exxos recap kit (0064) indicates that for C8 (25v/100uF) and C24 (25v/220uF) would be replaced by 50v/220uF. However my package contains still caps rated at 25V. I guess it's not a big deal, just curious why?
