Re: Lead-free soldering

Still using lead based, mostly because I got a massive roll for free a few years back. About 370C seems to be the butter zone for me.

Re: STE " It's dead Jim"

MagneticFever, I can recommend these from exxos' store:

I replaced a broken reset switch with one of these and it was a 100% perfect fit.

Re: The Union Demo on gotek?

Thanks that's really helpful. I'm guessing that if I install an ST emulator on pc, that I can copy the prg file to a blank disc image and then transfer that to gotek? Likely to work? I've not tried the HxC options myself, all my Goteks are FlashFloppy, but I find it useful to have an emulator on ha...

Re: STE " It's dead Jim"

I'd also have a look at the sockets. I've run into a few problems with the PLCC sockets that are often used, as over time (30+ years!) the contacts tend to push out of the way, and when you get a bit of tarnish on the chip and socket contacts. So it's worth removing the chips from their sockets and ...

Re: 1040 STF showing occasional rogue pixels

Apparently, RAM access has fallen down to 50% of regular ST performance. On the upside, the rogue pixels don't show up anymore. But, I see the occasional flash in the bottom 20% of the screen in Metrocross. It's rather subtile, more like a few lines dim during a single frame. The dimmed area in the...

Re: 1040 STF showing occasional rogue pixels

If I recall, if you are leaving the RAM chips in, you'll need to de-solder the bottom end of those 3 resistors and connect them to +5v to disable that second bank of 512KB RAM, a bit like if you added a Marpet or similar RAM add on. Double check this before you do it though in case I'm remembering i...
