TBBS is an acronym for The Bread Board System, although this explanation was buried in the documentation. This was different because "BBS" was most commonly used to stand for Bulletin Board System. The name was chosen because it drew parallels between an electronics "breadboard" (where the basis for any circuit can be built).
TBBS started out in 1983 as a single line Bulletin Board System (BBS) originally written for RadioShack TRS-80 CP/M machines, and was later ported to IBM-PC computers. Its advantage was that it could be fully customized by the system operator, so that no two TBBS systems looked the same. Other BBS packages at the time had their menu structures hard coded.
As time progressed, Phil completely re-wrote the TBBS program in assembler to operate on IBM PCs running under DOS. In 1988 he added a custom multitasking kernel that allowed multiple callers to access the TBBS system at the same time. Other BBS software packages could only achieve simultaneous user access by either running their software on LAN systems, dedicating one complete machine per modem, or under DOS multitasking software such as Quarterdeck's Desqview. TBBS achieved multiple lines all on the one machine. For those only wishing to run two lines, no additional hardware was needed - you only needed to used COM1 and COM2. For those wishing to run more lines, multiport serial boards from a company called Digiboard were used to allow up to 96 modems to be hooked into the one machine. At its height in 1996, TBBS could support more simultaneous users at full speed on less hardware than any competing BBS product. Many software companies, like Microsoft, and most computer hardware companies all around the world relied on TBBS for their online technical support and file download services until Internet web and FTP sites replaced the need for a direct dial BBS presence in the mid 1990s.
Add-On "Option Modules" were used to internally extend the TBBS feature set.
All in all, TBBS and its option modules were far beyond the performance and reliability of what other BBS authors could dream of.
In 1993 Phil Becker saw the approaching commercial migration to the Internet and started work on the IPAD (Internet Protocol Adapter) project. It was designed as an embedded hardware+software solution that originally focused on bidirectional telnet access to TBBS. It also provided other services (RAS, DNS, FTP, etc.) for those TBBS callers on dial in lines using the IPAD machine as a direct gateway. This allowed many IPAD owners to more easily become Internet Service Providers (ISP's) as BBS usage on the whole began to wane, caused by the growing popularity of the Internet.
The IPAD was extremely popular with commercial TBBS operators. Unfortunately it was very expensive and beyond the reach of most hobby TBBS sysops that had already invested thousands of Dollars into TBBS plus option modules for use on free systems with no hope of ever making a profit.
eSoft and TBBS went their separate ways as eSoft pursued the Internet market. All new TBBS development ended in 1997 and by the end of 1999 all technical support for TBBS and associated products officially ended. Interestingly new TBBS sales continued through 2003 as part of vertical applications built with the TDBS language.
TBBS is currently supported by a user support forum at TBBS.org IPAD is currently developed and supported by the IPAD Owners Association, Inc. eSoft is located in Broomfield, Colorado.
