Looking for the source code of COSTAR, DHCP and more

[Rochus Keller]

Maybe anyone can help me to find the MUMPS sources of the COSTAR (Computer-Stored Ambulatory Record, developed at MGH in the 1970s) and/or VA's DHCP (which later became VistA) applications. 

I would like to run these on my MUMPS 76 interpreter if feasible.

I'm generally interested in 

1. the DECUS 11-362 "MUMPS-11 Library Tape" 
2. the DECUS 11-380 "QUEST, Standard MUMPS Teaching Program, and DOC" (January 1978, by Robert Stimac/BCL St. Louis)
3. any pre-1982 MUMPS medical applications.

I already have the DSM-11 V3.3 image from bitsavers and the DECUS 1990 MUMPS SIG tape code.
