What is the maximum number of digits that may be used in the Octal System

Design a 3-digit BCD counter that: - counts from 000 to 999 if no button is pressed - Resets the count to 555 if both push buttons A and B are pressed Resets the count to 222 if only push button A is pressed - Resets the count to 333 if only push button B is pressed

Explain and draw a 7490 chip in a circuit of your own design. I want the actual chips drawn with the symbols inside, then a wiring diagram showing the interconnections. Power source and A, B, C, and/or D inputs may be added in the form of either buttons or switches.
