Just a heads up, it looks like these guys ripped off Serge Kiselev's 8088 BIOS [1]. [1] https://github.com/skiselev/8088_bios
A) it’s a cheap Chinese device, I’m certain some stolen open source code is the least of its infringements.
B) it’s licensed GPL, if they made no code changes (however doubtful) they didn’t really rip anything off.
