AlphaWindows

From Wikipedia, the free encyclopedia

In the early 1990s the Display Industry Association (an industry consortium in California) defined a standard AlphaWindows that would allow a single CRT screen to implement multiple windows, each of which was to behave as a distinct computer terminal.[1][2] Individual vendors offered products based on this in 1992[3][4][5] and after,[6] through the end of the 1990s.

These products were targeted at a low-end market:[6]

for users that don't need the processing power of a personal computer or the complexity of an X Window terminal, the AlphaWindow terminals and software provides the same look and feel of windows-based graphical user interfaces on an Alphanumeric terminal

The initial concept relied on custom (but low-cost) terminals which would support mouse interaction, (text) windowing support, and colored text.[3] With that, plus special host software, the vendors proposed to support semi-graphical applications "transparently".

[edit] Organization

The Display Industry Association was at the same location as Cumulus Technology (the same street address in Palo Alto, CA).[1][7] Cumulus was a manufacturer of displays since 1986.[8][9] Cumulus was heavily involved with development of the AlphaWindows standard. The members of the association in 1993 were[1], reading "/" as a partnership:

Terminal vendors
AT&T/NCR/ADDS
Cumulus
DEC
Link/Wyse
MicroVitek
Siemens/Nixdorf
TeleVideo
 
Software vendors
Cumulus
JSB
Nutec
SSSI

Only Cumulus was proposing both to develop the terminals and the host software. However, Cumulus did not survive — it went bankrupt.[9][10][11]

[edit] Software

JSB Software Technologies produced MultiView Mascot. As noted in Unix Review:[12]

MultiView Mascot helps users access graphical applications, such as Web sites and e-mail systems, from a character-based browser. It does so by mapping graphical applications to a multiwindowed character system. Although there is the inevitable loss of graphics and formatting, the result is surprisingly workable. A hot-key feature allows any old character terminal to offer switching between multiple applications at the same time, with no programming required.

As of 2007, the product is owned by FutureSoft.[13][14]

SSSI (Structured Software Solutions, Inc.) produced the FacetTerm session multiplexer.[15]
