Wish I had my Dad's old calculator. My brother and I would play with it at the office. It was as big as a typewriter and took many secs to do a square root. Cost the co $25k back in the 60's.
I still have my 1st PC, IBM XT clone 8086 /w dual floppies and RGB monitor.
Got all my old cell phones as well!
Got quite the tech dump here!
