Not sure how well it would work on Windows 10 era laptops, I'm using a 2002 era laptop running Windows XP...
There's a piece of software called Rufus. You can load that onto a USB thumb drive and set your computer to boot up off that. That'll boot you into pure dos. For my setup, that will let me run all the old RSS software.
Again, not sure how well this applies to you, but you also need to figure out the interface to the radio. My old laptop has a real DB-9 serial port, and I have a Motorola RIB. That's worked out just fine.
But getting USB ports to work with the old software can be a real challenge. I'm sure someone here has better skills at this than I do, but that's what I can pass on.
Might be worth hunting around for old laptops that you can salvage. Might make life easier.
