New electronic MDB hardware to be build for vending machines using RPi

I have old cigarette vending machines that still uses the RS232 protocol. Now these boards is old. Its unstable, and will not support new systems like Nayax.

How these old vending machines currently work.

1. Stackerless Note reader

2. Only gives R1, in change(very frustrating)

3. Old arcade type coin mech.

4. Cant use MDB note readers or coin mechs.

5. Cant use Nayax.

6. Max price of only R99,00

How I want the new RPi MDB board to be like.

1. It must use RPi with a MDB hat.

2. It must have a sensor on the bottom chute where the product comes out that will acknoledge that a packet of cigarettes was actually dispensed.

3. It must be able to use a Coin mech like the Jofemar J2000

4. On the board it must have 4 menus that you can enter using a mode button.

4.1 It must show total sales when pressed once.(hold in mode button to clear)

4.2 Total vends since the start made of the new board(unclearable)

4.3 Total sales since the start made of the new board (uncrearable)

4.4 Total change vended (hold in mode button to clear)

5. It must be able to use a MDB coinmech, MDB note reader, and MDB Nayax.

6. It needs to use a Powertip PC-1602-H screen for display.

7. I need to be able to set prices up to R999.

8. I should be able to connect to 50 lunar vending motors.

8.1 Every lunar vend motor has a micro switch, and there must be no sale allowed when switch is not triggered by a pack of cigarettes. (customer cant pay for a product that doesnt vend)

9. The main RPi Board must connect to 50 push buttons. Button 1 for lunar motor one)(no shared buttons)

I want the Rpi with the MDB hat to be the main board. Then a seperate board where all the motors and buttons plugs in. 1 button for each lunar motor.

After I bought the RPI- with the MDB hat, I want to person helping me to teach me how to duplicate this process so I can build hardware for all the machines I have. Helping me install the software that was created onto the Rpi

Thank You
