TWS is true wireless stereo, it refers to earbuds that can be addressed separately (Left/Right Channels), your ISOtunes recommendation would fit the bill.
I forgot the details but the 2005 Most Wanted has an unofficial update pack that brings widescreen and other creature comforts. It was well supported except I could never get lan-play to work on my Win10 hosts. I wish I had a link but everything I find is piecemeal and the patch I had years ago combined the popular ones to one patch.
There has been numerous attempts over the years by unknown actors to essentially crack TOR by controlling nodes. There have been a few theories about who, but it has been a sustained effort over a period of years that has at times controlled up to an entire quarter of the Tor network, leading many to believe state actors and/or law enforcement are behind these man-in-the-middle attacks.
It would presumably be the same it was essentially just a connection to the ISP so it is the same kinds of attack vectors browsing the wider web (arguably less since you presumably could call from random numbers and/or change ip address easily). The only one big thing I could think or is that since plain old telephone lines (POTS) were often directly interconnected (party lines/multiple phones to one line), someone could more easily pickup/tap the line to eavesdrop compared to broadband. USB modems do exist I believe 56k is the fastest you can find (iirc there was some FCC regulation limiting to 53k to prevent telco issues going faster, I believe 56-64k was the technical limit), but if you have a 2G phone that supports Circuit Switch Data you can use that and try out the magic of WML cards (specially formated html pages to run on phones) making up a WML deck / WAP site (mobile version of the site). There is a list of WAP sites here that may still work http://pubquizhelp.com/mobile/bestwap.html
Most high volume printing (like shipping labels) is done with thermal printers where the heat turns chemicals on the paper black. These chemicals usually can withstand water but not alcohol so spraying with pure alcohol and wiping off usually will blank the paper entirely.
