12C Platinum vs. 48GX vs. 50g (Speed Test)

[Gamo]

I got three 12C

1. HP-12C+ (made in China used Two Coin batteries)
2. HP-12C (made in Singapore used Three Button batteries)
3. HP-12C Platinum (made in Philippines used Two Coin batteries)

12C+ got the worst keys press with keys delay and bounce often this is very annoying when input program but this one is the fastest computation speed.

12C Singapore version is the best feel to use with nice feeling with good key press. The speed is not fast but you will get originallity of this classic 80's calculator.

12C Platinum Philippines version is the best of all 12C Platinum I only own Philipine version and
this one keys is all good no missing keys and this one give you decent computation speed with very big programming capacity and option to use ALG mode if user prefer.

If you like to observe the speed by the use of the [IRR]
You can try this "Polynomial Equation Sover" using the HP-12C with "Cash Flow" function.

Solve: 3X^3 - 2X^2 + X - 11 = 0

Setup Steps: [FIX] 4
[CF0] -11
[CFj] 1
[CFj] -2
[CFj] 3
[IRR] .... keep compute .... then display -41.7483

Final Steps: 1 [%] 1 [+] [1/x] Answer: 1.7167

Remark: This will only find real root
