alt Hacker NewsI work at a multi billion dollar facility for a Fortune 100 company and we still depend on DOS. Keeping the mandatory DOS machines going is an exercise. Especially integrating them into modern systems.
Edit: There is no required hardware, however maintaining a stable serial connection through a VM and timing issues due to faster hardware has been fun.
The serial port stuff is very close to what I'm working on - what's on the other end of the connection? What does "integrating them into modern systems" look like for you: getting data out/pushing data in/both?
