The 576 was based on the original 7000 series,
and the 577 was based on the modular 5000 series.
The 576 was intended to do everything discrete
semiconductor wise.
The 577 was geared towards low current discretes,
opamps, and 3 terminal regulators.
They are complementary instruments, each covering
a different part of the V-I spectrum, but do not
fully replace each other.

I saw this 577 Curve Tracer show up on eBay and it sold for $256. Not sure if that power-up trace indicates an issue (not having had or operated a curve tracer, I don't know what the power-up trace should look like). Following-on to conversations in this forum about the the 576, I've been keeping my eyes out for a 576. Is there a significant difference between the two?
