$100 is very cool. Even if you toss 'some' of this stuff, you still made out like a bandit. The Megohmeter isn't likely useful to you, The Eico 955 is not a good tester at all, and you'll never use the bar generator (unless you fix old TV's on the side, and didn't tell us).
HOWEVER, The Tek 434, while 'just' a 20MHz scope, is still Tektronix quality. Nice. Sometimes the probes (very important to have the 'right' ones) are worth more than the scope. But I've seen the scope with the manual and four 'good' probes go for almost $200, so you did good just on the scope alone. +1!
The RCA VTVM is real cool. I use one to test tremolo oscillators, or check potentiometers for worn spots, or check coupling capacitors for leakage, and more. Low resistance or voltage measurements are possible as well. Real nice to have, and you have the proper probe. +2!
The Genometer is OK, but old. The manual is here; SUPERIOR INSTRUMENTS MODEL TV-50-A GENOMETER Service Manual free download, schematics, eeprom, repair info for electronics or here; http://bama.edebris.com/manuals/superior/tv50a. It will work as an audio generator, but the sine wave won't be the cleanest you've ever seen. It's more an RF generator. Here is an eBay auction that the seller had no bids at $10; Superior Instrument Co Genometer TV 50 | eBay
That's all I see quickly. If the HP generator is the usual HP quality, there's a +3 for you. Usually a reall nice generator, even the tube ones.
Man, the more I read what you got, the more I envy you. Wow. That's how you do it without eBay and the crazy prices.
