Yeah. The replacement scope for my GOULD was a TEK TDS3032 with floppy drive. Takes as much as a minute to capture the screen. Getting harder to read those floppies from Windows Systems. Not really possible to take it apart and insert a floppy emulation USB drive. So I bought a TEK MSO3034. This has USB and Ethernet. Takes forever to start up whatever OS it has. Hopefully will have at least a 15 year life. Unlike my Rhode and Schwartz Spectrum analyzer which was lucky if the battery pack lived for more than 6 months. At over $1K to replace it I stopped. And I won't buy another Rhode & Schwartz.
