The 3000-L Listserv repository is the HP 3000 resource that's been in the longest continuous use for the MPE/iX ecosystem. HP had a Jazz website for about 13 years, content that was carried over to Fresche Legacy's servers once HP's labs closed. 3000-L was online for about a year or so before the NewsWire entered the Web.
The content on the 3000-L was a big reason I believed we could do a monthly HP 3000 newsletter. We curated and learned, education and advice we shared with readers. Even after 26 years, 3000-L can be searched for answers that go back to the era of MPE/iX 4.0.
That repository is full of history about the people who have created the MPE ecosystem, too. with enough patience, most answers will be hiding in the hundreds of thousands of email messages. All are logged by subject line. 3000-L can be searched within date ranges, too.
3000-L was once so robust that we could publish a column about its gems once a month as part of the first 10 years of the NewsWire.
The columns are archived in our 1996-2005 pages. We called them NetDigest, and for awhile they were written by John Burke, who helped us found the NewsWire with his knowing voice and deep technical experience.
For the source material for those columns, refer to the 3000-L search panel.
For the columns, refer to the Tech Page of the '96 - '05 issues. Once you arrive at the Tech Page, just do a search within the page for the phrase net.digest. We've got 106 columns there.
