Lucid 3-D

From Wikipedia, the free encyclopedia

Lucid 3-D[1] was a spreadsheet package that began in the MS-DOS era;[2] Windows support came later. [3][4]


Sam Redman[5] and Michael Stanford[6] incorporated as PCSG corporation (Portable Computer Support Group).[7]

Their Lucid 3-D spreadsheet was marketed by DAC.[8]


Lucid 3-D was considered noteworthy at the time for being "the only major memory-resident spreadsheet available for the PC."[9]

The selling point of the product was being "three dimensional. Any cell of the spreadsheet can contain a complete other spreadsheet that you can access with a single keystroke."[10]

Another technical feature was what their ads called "not only minimal recalc, but background recalc"[11]

The Windows versions could display "up to nine overlapping spreadsheet windows."[1]

File extension[edit]

Data files were stored using the extension ".lcw" (Dot LCW).[12]
