midrange.com was created to be a free online resource for IBM i (formerly System i, iSeries, & AS400) professionals.

midrange.com started life as The Midrange System BBS ... which was created as a cheaper alternative to News/34-38's NewsLink service. The first hardware the BBS ran on was a Compaq Portable II with a 12mhz 80286 CPU and a 20mb hard disk.

In 1993, the internet was starting to become popular, and on a lark, the midrange.com domain was registered and a UUCP account was setup with a local ISP.

Using software that allowed the BBS forums to be gated to email based mailing lists, the first list hosted by midrange.com was created ... MIDRANGE-L.

About a year later, the BBS system suffered a catastrophic hardware failure. Obviously this caused a bit of a disruption. After careful review, it was determined that the BBS concept would be abandoned, but the mailing list was still quite viable. After a bit of research, a new Linux system was installed and mailing list software setup.

midrange.com was created, is maintained, owned, and operated, by David Gibbs. David is a Principal Software Engineer for PTC

All mailing list's hosted by midrange.com are available in a searchable web archive. The archives are broken down by list, year, and month.

The software used to create the archives makes a 'best effort' attempt to mask email addresses.

The archives can be found at archive.midrange.com.
