Looks like an ancient Wang of some description.

So, he's been cleaning …

Yes, but you are of course talking about a single strand of protein that has to be broken down somewhere...

Yeah, but it's still the study nobodies actually done. Do you have any idea how many studies could be performed but aren't? Having said that, why do you think hepatic damage secondary to viral infection isn't something already being studied? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4179142/ …

I'll try anyway the OpenWRT solution but need to configure it for usb_ethernet packages and I remember was quite long to do. Why? What device are you using to create the bridge? It's a mobile 3g wifi router that has the usual usb-ethernet connection and I'd need to bridge it to the ethernet port of …

All I said was that if you can’t afford or find a GUS today the AWE64 sounds pretty good to me and has good DOS compatibility. Better than the Sound Blaster 16 if you ask me. You did say more than that, but it's ok. :) The AWE64 is fine as it addresses several of the weaknesses of the SB16. It has …

About temperature control for old (or pretty modern cheap made) weak PCBs that is mandatory if you want to not destroy further. First time soldering in a facility very rarely lead to bad consequences, so even most cheap "goods" can survive it. Smaller pads and traces with less thermal mass are much …

You need to control temperature to avoid possible damage to weak PCB or component. I have no issues with desoldering ROHS components with old copper iron without regulation, just need proper flux and wet tip. These two statements are contradictory. Using a temperature controlled iron for both …

You can also use a cheap Ethernet->Wifi bridge, which will circumvent any requirements for the OS, since the bridge does all that and the OS just sees a standard Ethernet connection. That's also a nice idea. I was thinking eventually if everything will fail to work, using a raspberry pi as router …
