That site is now a pay site to access manuals. Low price of $12/year. He encountered a lot of foreign traffic (ISIS) early last year and had to make it more secure. For your $12 you will get a user ID and a Password and Chris (the guy running it now, Steve has passed) is real fast at responding to your requests. Contact him via email first (he responds very quickly) and he will send you all the info you need to get access.
