Known TI models with key bounce issue?

[Gene]

Accutron is not far off the mark, but it is a bit of a generalization.

So here's another generalization. :-)

If you go to datamath.org and are looking at the scientific / financial portion of the album:

MOST of the time, the key bounce problems occur on these product lines:

Majestic
The first and later Slimline LCD range
and MOST egregiously, the slanted LCD first generation.

Let me illustrate with a numeric scale, where 10 is awful, nearly give up trying to enter a number and 1 is the what? initial HP 35 keyboard in 1972 ? :-)

Slanted LCD first generation - 9
First and later Slimline LCD - 6
Majestic series - 4

On the other hand, 90+% of these models have always worked just fine for me:

SR series - SR10, 11, 16, 16II, 50, 51, 50A, 51A, 52, 56, 58, 58C, 59. Note the 57 is more a majestic line machine.

My 2 cents. I don't deal with the non-scientific or non-financial models. No 4 bangers for me.
