Thandar SC-110 miniature battery powered scope
Gebruiksaanwijzing
This is a 10 MHz scope that runs on four C size batteries. The CRT is one of the smallest I have ever seen and the trace is very sharp. It is a electrostatic defection type CRT like they used in the Sinclair Microvision pocket TV. Thandar was related to the Sinclair instrument division.
