You have to use an old DOS computer with an extremely slow click speed.
A couple of years ago, I did see some one advertising brand new DOS only computers for sale with a slow processor speed from China, but I was not willing to go down that rabbit hole since, there was no technical, media, or connectivity information provided on the computers. I don't recall the cost, but wasn't unreasonable.
I had a XP Pendium I computer that had both the floppy 3.5 disk drive and a serial port, in addition to the CD drive and USB port, converted to a DOS 6.2 only computer that works very well with the VISARs, HT1000, and MT2000 radios, but the computer apparently too fast for the Sabers, P110 and GP300 radios. It will go through reading the radio motions, but when you go to view the file, there is no data to view.
It was very difficult to find some one still having the software for DOS. Of course, the DOS operating system doesn't recognize the CD and USB.
