                            So far I've only glanced at the page. 
                            
                            One observation is that Mattessich completely misses the point. I don't 
                            begrudge him his work in accounting in the 60's but it had not the slightest 
                            influence on VisiCalc. It was one of many online financial programs. 
                            I worked on some systems while at Interactive Data in the 60's and 70's. 
                            But VisiCalc was not an accounting program at all, it just made it possible 
                            for people to do accounting. Programs that were overly tuned for such 
                            function (Javelin, Lotus Improv, etc) completely failed. 
                            
                            As you explain spreadsheet is a simply a piece of paper spread out to allow 
                            you to work on problems. But business transactions are not an important use 
                            -- production planning and other applications are more important.
                            
                            What made VisiCalc novel was the ability to not only interact but have it learn by example. Again, VisiCalc
                            doesn't summarize or do anything, it is just a tool to allow others to work out
                            their ideas and reduce the tedium of repeating the same calculations.
                            
                            As to the details, Dan did a prototype in Apple ][ Integer Basic. We'd already 
                            been planning to work  together. Dan's code was not the basis for mine, 
                            the example was key. What was important were the features we'd left. We'd 
                            already discussed wall-sized interactive displays with live graphics but 
                            the systems weren't up to it. More important, the grid provided the 
                            simplifying structure that made it a spreadsheet as a opposed to a more 
                            general surface.
                            
                            As an FYI, Mitch was the VisiCalc product manager at VisiCorp. Also, we 
                            invented the A1 notation for VisiCalc. IT was Multiplan that did 
                            the R1C1 stuff.
                            
                            As to VisiCorp's suicidal behavior ...
