[HECnet] RSTS/E patches

I previously created a Github repository for various DEC things, including updated DECnet/E utilities. I thought that the RSTS patches I had posted in the past were there also, but that wasn't the case. I've added a "patches" subdirectory, which contains the patches I have collected. I just added a new one, which fixes a bug encountered when running SIMH set to be an 11/94. In that case (and possibly some other similar variations) RSTS tries to figure out the line frequency and gets it wrong because SIMH executes much faster. https://github.com/pkoning2/decstuff is the repository. paul
