[Leica] Re:SD cards in M8

[jhnichols at bellsouth.net (Jim Nichols)]

Luis,

I never used Visicalc, though I have heard of it.  I became very familiar 
with Lotus 1-2-3, because our company management adopted it for use in 
balancing workload and personnel.  I now use Excel, but didn't make the 
change until I retired.
