You sound like you need some VMs. Particularly for whatever is on that old laptop.
Have been working on moving what I can to a VM, but the systems I develop require physical access, and when I've asked, I've been told there is no way to give a VM access to the laptops ports.
Many of the systems / devices are on physically isolated networks, use RS-232 or USB for access, etc.
If there are netsec approved ways of passing physical ports to the VM that would solve a ton of my issues.
