History

GT Power was originally a telecommunications/terminal application, known as GT Powercomm, which could be used to dial-up other BBS systems. As time passed, a host mode

 was written into the application which allowed the user to accept incoming data calls. Before the release of version 13.00 (released Autumn, 1987), the host mode portion of the application had been expanded to become a full-blown BBS host application, complete with message and file areas, file uploading and downloading

The name was shortened to GT Power sometime before the release of version 14.03 in the Autumn of 1988.

With version 13.00, P & M software began offering a proprietary Netmail Suite; a set of applications which allow GT Power BBS systems to connect and exchange routed person-to-person netmail. By the time version 14.03 was released, the suite was expanded to include the ability to also exchange echomail between systems, similar to FidoNet

 that disabled any registration reminder delays in GT Power.

The Netmail Suite consisted of a mail transfer program and two mail handling programs. The mail transfer program, called MDRIVer, was used to dial other GT Power systems, to authenticate their identity, and to transfer mail between the two systems. The mail handling programs were used to "bag" mail and prepare it for transfer (MBAGger), and to unpack received mail and distribute it to the proper message areas (MDIST).

P & M Software released its last version of GT Power, version 19.00, in September, 1994. In mid-February, 1998, it was announced that P&M Software had sold the GT Power source code to New Millennium Software. New Millennium renamed the project GT 2000 but, by the end of April, it was announced that New Millennium would not develop the product. The source was sold again to Dennis Berry, a GT Power sysop.

In late 1999, Berry released a Y2K bug fix for the Netmail Suite. A third party Y2K fix for the Suite, as well as other third party companion software, was also released. The GT Power application itself appeared to have no Y2K issues, and the latest release remains at 19.00.

The source code and rights were sold to Tom Watt in June 2008 and he has resumed development of GT-Power. For the first time since Paul stopped development, the source code has been made to compile the EXEs as they were last released in 1994.

Third party software

Many third party software packages were developed to support the GT Power BBS. Early distributions of GT Power included a third party application called GTCTL, written by James Davis, followed later by Sysop Tools, written by Chris Smith. Both were later replaced by the P & M SYSOP program. Unlike SYSOP, Sysop Tools had an ANSI-style DOS graphic user interface. All three were used mostly for user and control file maintenance. Other third-party software includes:
  • external message readers, allowing the sysop to read & enter messages locally without logging in to the BBS;
  • a QWK mail application, which could be added as a door or external menu option, that pre-dates and is more configurable than the built-in version (it could also be used for QWK networking);

A third-party mail transfer program, called Mailrun, was developed which allows GT Power Network systems to transfer mail using the bi-directional HS/Link protocol. In theory, the use of the bi-directional protocol (which sent and received files at the same time) will shorten the length of dial-up netmail calls, saving the sysop some long-distance phone charges. This program can be used as a replacement for the proprietary MDRIVer program, but requires the use of the proprietary MBAGger & MDIST programs. With proper setup, Mailrun can co-exist with MDRIVer, allowing systems to use both programs to transfer mail. Mailrun is freeware

, but does require a free key code from the developer in order to connect with other systems. Mailrun is stated to be compatible with GT Power versions 17.00 through 19.00, but can work with earlier versions.

In addition, in 1989, a third-party mail handling application, called JDMAL, was released. It was developed by James Davis, who had previously worked with Meiners in developing the proprietary suite. It could be used as a replacement for the proprietary MBAGger & MDIST programs, but did not replace the MDRIVer program. The last few releases of JDMAL, versions 8.1 and later, were freeware, and were compatible with GT Power versions 13.00 through 14.03.

The GT Power Network

As the GT Power software application evolved to include a BBS host mode, P & M Software developed a Netmail Suite package which allowed registered users of GT Power to participate in the GT Power Network. With this Netmail Suite, GT Power BBS systems could exchange netmail and echomail with each other.

As use of GT Power increased, the network grew. At various times during the late 1980s/early 1990s, the Network included hundreds of nodes in the continental United States

.

Like Fidonet, the GT Power Network offered both netmail and echomail. Where netmail is usually system-to-system, person-to-person mail, echomail was intended to be read & possibly replied to by users on all GT Power Network BBS systems. Each echo had a different topic, such as politics, computer technical support, and ANSI art. The GT Power Network's application of echomail was different from Fidonet in that echomail messages traveled back to the moderator's (or "sponsor's") BBS before being distributed to the rest of the network. This had the advantage of allowing the moderator to review every message before it was allowed to echo to the rest of the network, creating the potential for a truly moderated echo conference. On the downside, a slight disruption in network routing could cause active echos to appear quite stale.

Around the beginning of 1990, there was a rift in the GT Power Network, resulting in the formation of a second network based on GT Power. The Alliance of Free Sysops Network, or AFSN, was formed, with some GT Power sysops finding ways to participate in both networks. By 1992, as AFSN sysops began migrating to other BBS software, the network had expanded to include both GT Power and QWK networking nodes, some of which had never run GT Power software. The AFSN either folded, or merged with another QWK network, sometime in the late 1990s.

Like many other BBS networks, as use of the Internet increased, the GT Power network began a decline. Today, the GT Power Network continues on, albeit on a much smaller scale than before. Many nodes on the network today participate in echomail via QWK networking as the former GT Power sysops have migrated to Windows and Linux

GT Power today

Most GT Power sysops have either retired their BBS systems or have migrated to other applications. Nearly all of the remaining GT Power Network BBS systems have replaced their dial-up networking with forms of mail transfer that take advantage of the Internet, by using either e-mail file attachments or some form of automated ftp.
