Disposal of my collection

[Palmer O. Hanson Jr.]

In late 2013 my remaining kidney started to fail. As a result I am now undergoing dialysis three days every week. In addition I celebrated (if that is the right word) my 85th birthday on jnFebruary 1st. Due to the combination of failing health coupled with advanced age I have realized that the time has come to dispose of my collection which consists of 40 HP's, 160 TI's and 500 calculators by other manufacturers, I also have 180 slide rules and about 50 mechanical calculators ranging from push-down calculators to to Fridens. You can see specific examples of my mechanical collection in my presentation "Calculating before Calculators" at the HHUC 2012 conference.

In the coming days I will be listing the HP's for sale in this forum
