Publisher and distributor of microcomputer software.
Founded in the late seventies under the name TRS-80 Software Exchange (as they initially only sold software for the Radio Shack TRS-80 microcomputer), the company was associated with SoftSide Publications and sold many programs that were also published in SoftSide magazine.
While the cassette tape was the most common form of media used by the TRS-80 Software Exchange, some of their order forms included an offer to transfer any number of Level II TRS-80 programs to diskette for a $5.00 fee, resulting in the possible existence of "custom" compilations.
In 1979 the company's name was changed to The Software Exchange (TSE) to reflect that it was also selling software for the Apple II and Exidy Sorcerer platforms. It was around that same time that a Boston Radio Shack dealer served TSE with an injunction preventing their use of the name TRS-80 Software Exchange at the Boston Computer Show (an incident described in the November 1979 issue of SoftSide magazine).
Beginning with the March 1981 issue of SoftSide, TSE software titles were marketed under the name TSE-Hardside. That name was used until the July 1981 issue, at which time software titles were marketed under the name SoftSide Selections. That name remained in use through the March 1982 issue of SoftSide (and would return, beginning with the March 1983 issue, as the title of the platform-specific inserts that were sent out to subscribers).
A few software and/or hardware advertisements in the April, May and June 1982 issues of SoftSide magazine briefly resurrected the TSE name. However, following that time it appears that all SoftSide-associated software was marketed directly by SoftSide Publications.
