Re: RGB to HDMI does this work with a ST

So we're back to 15khz then? So a monitor with both VGA and DVI that can only display ST-High through VGA will also only display ST-High through DVI with this converter?

Re: which archiver/zip /packer is cubase falcon packed by

That output looks weird. Either corrupted or wrong encoding. Can you change encoding? As in ANSI, UTF8 or whatever options there are.

I tried to google using the hints but no dice. Looks like it says Cracked by HellRaiser maybe?

Wow. Soldering that is extremely difficult even if you manage to scrape the film without damaging the copper. I guess the copper was fairly thick? I could never be able to fix the Stacy keyboard ribbon.

Re: Recapping an ST board - is it worth?

To answer the other question "Did you ever find a faulty electrolytic capacitor on the ST motherboard?", it depends on the definition of faulty. ESR gets worse over time on electrolytic capacitors. There's no way around it. So a 30 yo cap has a higher ESR than it did when it was installed....

Re: Recapping an ST board - is it worth?

It's only worth it if you succeed. Is it worth attempting? If you're having problems that could be related to caps, sure. If you don't know what you're doing, when to prioritize in ESR, when increased capacitance vs original is better, then no. I've fixed dead PSUs with new capacitors but problem co...
