4000 series are really much more static sensitive than bullet proof ttl
there are pros and cons to everything 4000 series can use a higher VCC
where ttl is 5V
if you plan using 4000 series get him a wrist strap and a bench pad to
attach it to
grounding it all to earth.

I’ll guess that they both need rebuilding; I have the instruction manuals, though, so maybe that is lesson 1? Is the TekScopes group the best place to find probes for one or both?
