Making your own TM500 containers, some surprises!
Good advice for scavenging parts for a TM500 plugin. Take care with the 7k bottom extrusion. It has a tab to land the latch spring. 7k mainframe rails have a slot to accommodate the latching mechanism

Readout for 5s14n - please validate my idea
I cannot say about the 5S14N, but only the 5400 group (5440, 5441 and 5444) of 5k scopes are equipped for CRT display of readout. If you don't have one of those mainframes, your project will be a bit
