Hi
I'm looking to convert my game show indicator lockout circuit from the original design using 14000 / 4000 series logic to a micro-controller based design, but I do not have a clue what to look for.
Here are the system specs:
System requirements:
If I could get info as to what I'm looking for in a micro, in relation to I/O, peripherals, and anything else to consider as I'm totally new to micros.
Also I'm not set on a particular companies micros, so I'm game for almost anything as long as the tools are easy to use.

I'm looking to convert my game show indicator lockout circuit from the original design using 14000 / 4000 series logic to a micro-controller based design, but I do not have a clue what to look for.
Here are the system specs:
- 15 contestant switches N.O.
- 15 corresponding LEDs and aux output in parallel
- 1 LED that comes on if any of the above LEDs is lit
- a reset switch to blank the LEDs and reset the latches
- a buzzer that beeps 0.5s to 1s when a contestant light is triggered or the timer reaches 0
- a timer package that has 5 different push button inputs
- a 5s or 30s on one switch that is selected automatically based on whether or not a contestant has triggered the system
- a 45s switch
- a 60s switch
- a timer pause / hold switch
- a timer reset switch
- a 2 digit 7-seg display
- the timer uses a divided 60Hz signal input coming off of the mains transformer
System requirements:
- Inputs debounced
- timer display can be driven separately
- LEDs can be driven separately
- current systems operate on 8 Volts regulated, with 12 volt AC input clock signal. ( the ability to operate at this voltage is preferable
