The Datamath Calculator Museum DCM-50A (PLAYGROUND) is based on the generic DCM-50A Platform to access most features of calculators and certain features of products other than calculators that are not covered by the scope of the DCM-50A (TMS0100, TMS0800, TMS1000, TMS1200 and TMS0900) and the DCM-50A (OTHERS) category. It consists on different printed circuit boards (PCBs) that can be stacked on top of the DCM-50A Platform:

• DCM-50A (PLAYGROUND) FRAME: Plug-In Carrier to access all voltages and signals from the DCM-50A Platform
• DCM-50A (PLAYGROUND) DIL42: Daughter Board with 42-pin ZIF Socket, Patch Field, Diode Matrices, Push Buttons, SPDT Switches and Pin-Modifiers
• DCM-50A (PLAYGROUND) BB400: Daughter Board with Solderless Breadboard (400 connections), Push Buttons and SPDT Switches

To access all features of a Non-TI single-chip calculator circuit, the schematics and layout of the DCM-50A Playground BB400 Adapter are providing accordingly:

• V_SS, V_DD and V_GG access from TMS0100 and TMS0800 Pin-Headers
• Digits Outputs D1 (rightmost) to Digit Outputs D11 (leftmost) access from TMS0100 Pin-Headers
• Segments Outputs SA to SH and SP from TMS0100 and TMS0800 Pin-Headers
• Keyboard Inputs KN, KO, KP and KQ TMS0100 and TMS0800 Pin-Headers
• TMS0100 CLK Oscillator from Jumper-Header J9
• Digital Discovery DIN0, DIN21 and DIN22 Signals from Jumper-Headers J10, J11 and J12, respectively
• Digital Discovery DIO24 and DIO25 Signals from Jumper-Headers J9 and J13, respectively

Please notice that the DCM-50A PG Frame Adapter needs to be plugged into the leftmost TMS0100 and center TMS0800 Pin-Headers on the DCM-50A Platform. It also connects to five Jumper-Headers on the DCM-50A Platform.
