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 Software of Dallas, Texas.[8]
Features
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
Data files were stored using the extension ".lcw" (Dot LCW).[12]
