I'm looking for any information about IC's - one chip osciloscopes, just like the ZM407 from ZMD-Dresden (that is no longer being produced). I'm also looking for some sources of information, how to build that kind of osciloscopes (to about 20 ÷ 30 MHz) that use PC - If you've got some information or schematics, please share them and PM me.
Thank You very much for any help.
