If you have documentation or actual experience with the PSL, we would like to hear it.

Prototype Module 57F7924

A kit that includes one standard-length prototype card and a complete module case. Gives your projects a finished, professional look and protects the components.

All of the cards feature plated through-holes and a gold edge connector for easy building and reliable performance. Microchip for interface between module and PSL unit. Each card is also supplied with an "ID" chip (74HC541) that allows the Base Unit to identify the custom circuit. These cards may be used with either the Base Unit or the DIO Module.

MM74HC541 Diagram

MM74HC541 Octal 3-STATE Buffer (IBM used a generic "74HC541")

Note: Buffers start with Pin 2 (A1) over to Pin 9 (A8). G1 is Pin 1 and GND is Pin 10.

ID Code

  MSB             LSB
ID A1 A2 A3 A4 A5 A6 A7 A8
F0 1 1 1 1 0 0 0 0
F1 1 1 1 1 0 0 0 1
F2 1 1 1 1 0 0 1 0
F3 1 1 1 1 0 0 1 1
F4 1 1 1 1 0 1 0 0
Note: "1" means tied to +5v, "0" means tied to ground

IBM wants you to use an ID code above "C0" and below "FE". The left character is set via A1-A4, the right character is set via A5-A9.

ID Microchip Circuit

Note: There are some differences between the datasheet drawing and thecircuit drawing. Don't wire this blindly following the positions, you must follow the Pin Functions!
