Q: Where can I receive support for the Rainbow?
Since the Rainbow 100 is a product of Digital, Encompass technically does support the Rainbow still. Encompass, formerly DECUS (Digital Equipment Computer User's Society), maintains an archive of software and documentation for the Rainbow and other Digital products. The information they have is not readily accessible, however, and must be specifically requested.
For help from users, one should read the Usenet groups:
comp.sys.dec.micro comp.os.cpm alt.sys.pdp11
Rainbow users write in both these groups occasionally. Many read these groups on a regular basis. Rainbow questions in the first group should receive replies in no more than two days usually. The second group receives considerably less Rainbow-oriented traffic since it covers only one of the Rainbow's many operating systems.
