DR/MS/PC- DOS
Why keep using DOS tools? There are some tools that have not been duplicated in the Windows or Linux Worlds of which SPFPRO is a prime example. DOSBox is an excellent tool for running DOS programs under Linux/Windows without the need of a Virtual Machine.

With Microsoft's enforced demise of XP and the Win8 disaster, it may be time to finally jump to Linux. There is no reason to abandon older hardware just because Microsoft needs to get everyone into a subscription revenue model. Puppy Linux is an excellent choice, can be booted from CD/DVD/USB, is extremely compatible with older Video/Sound/NIC/WiFi hardware and comes with an abundance of tools. Under Linux you can mount your laptop hard drive and run DOS/Windows programs from it without modifying the programs. Wine works well with Puppy Linux. Loads of tools and all free!
