Keithley 615 Electrometer Printer Board Recreation

==================================================

This repo contains modern reproductions of the buffer/printer PCBs (PC209, PC218)

for the Keithley 615 electrometer.

Boards

------

 - PC218

   - Signal inverter/buffer board

   - Recreation of the origional PC218 schematic using modern SMD components is

     in the `PC218` directory

   - A simplified version using more modern ICs can be found in the `PC218v2` directory

 - PC209

   - Signal inverter/buffer and trigger board

   - Simplified version of the origional board can be found in the `PC209` directory

     - Same inverter/buffer scheme as PC218v2, with the origional trigger pulse

       generator and logic reduced down to discrete transistors, to simplify design.

 - Digital Interface Board

   - This will be a new board designed to connect to the 615 via the 50-pin

     Centronics connector

   - Planned features:

     - Passive data collection

     - Active triggering

     - USB-serial

     - RS-232 via DE-9

     - Ethernet
