@ernie @vwestlife I guess #OS3 was not an option to avoud confusion with #System360 devices and #OS4 was propably some codename that never went further.

OFC #OS5 may be unrelated to #OS2 entirely.

It shurely is unrelated to #OSv which is designed to only run in VMs!

I have to run this now. lol
#OS5 #DOS

@lovelymono Hilariously, the hardest part is learning to use #OS5 because it was made by someone who saw fit to create his own kernel fwiw.
