Thanks for the support!
Some more information here:
I ordered a used Thinkpad X250 wich I will use in most cases, and in my opinion will fit best for this as it is quite actual hardware (2015) that is still available and of good quality. The X250 will arrive next week and then I will begin to start. The X250 is very similar to the T450s I had some years ago, that worked quite will with ARcaOS (see Blondeguys Hardware offer as well
http://www.blondeguy.com/computer/phenobopeep.html), and Mike Kölling thankfully provided already a lot of information about his X250 here and at os2.org.
I am still looking for good and license free background music and try to build a short trailer used be each video first.
In addition I already fixed the way I want to organize the videos:
0000 - 0099 ArcaOS Inside & Virtual
including requirements, BIOS, Installationmedia, ArcaOS inside Virtualbox, VM Ware, Virtual PC...
0100 - 0400 ArcaOS Hardware & Drivers
including test on different Hardware (like the X200T, the TP25, the X250, Sony Vaio Pro 13....), compatible Hardware at all etc., Drivers
0500 - 0900 ArcaOS Application Software
including Softwaretest, Reviews, Games and so on
Stay tuned :-)
