I haven't been paying proper attention and ended up asking the wrong person some questions.
Has anyone successfully installed DECnet on TOPS-20 on SIMH using Johnny Erikkson's code? If so can you explain which virtual tape you used and what documentation you used to explain the procedure? >From what I have been able to discover it seems that the virtual tapes that are available do not match the documentation that is available, so I am having trouble marrying the two and following a procedure to get it installed.
