+Useful files to boot CP-V on the simh sigma simulator
 
 This repository includes a bootable PO tape and a sigma.ini file that can be used to boot the CP-V system on the simh sigma simulator.
 
+The PO tape and cpcpdoc.txt files were provided by Keith G. Calkins from his archive of CP-V material at https://www.andrews.edu/~calkins/sigma/.
 
+The cpcpdoc.txt file is a description of booting CP-V using siggy, a dos based simulator written by Keith and George Plume in th 90's.  This may help someone new to CP-V to get started.
