VisiCalc required 32k of memory to run. A chart from a roundup of spreadsheets in the 1982 Personal Computing magazine lists eighteen spreadsheets.

It was immediately acknowledged to be a better product than VisiCalc. In December 1982 Gregg Williams wrote in Byte that 1-2-3 had ‘many more functions and commands than VisiCalc’ and that 1-2-3 was ‘revolutionary instead of evolutionary.’ PC World called it ‘state of the art.’&quot;</p><p><br /></p><p>I&#039;m still, as you, am trying to recover/expand mathematical data equations from older spreadsheets by using newer versions which I consider too heavenly-minded, but for just mathematics/me, No Earthly Good!</p><p><br /></p><p>I appreciate your advice and hope/wish that I find a mechanism that won&#039;t require a 64 bit processor, non-backward compatible program/O.S..</p><p><br /></p><p>I&#039;ve tried same with frustrating results.</p><p><br /></p><p>So, What coins are you collecting, as I&#039;ve been locating competitively priced certified U.S. Gold for numerous others that are frustrated with pricing above &quot;Spot&quot;, which I&#039;ve decided to acquire with lowest premium, and share &quot;Pro Bono&quot;![/QUOTE]</p><p><br /></p>
