I again wasn’t looking to start another calculator project when this Burroughs C5155 calculator showed up in one of my automated searches. The price including shipping was a bargain, so I purchased it.

I again wasn’t looking to start another calculator project when this Burroughs C5155 calculator showed up in one of my automated searches. The price including shipping was a bargain, so I purchased it.
I decided to see what I could do about the temporary modification to the Burroughs C 3207 multiply key indicator, before it became a permanent modification.
Well I just finished working on the APF Mark 1 calculator so I wasn’t looking for another calculator project right away, but I stumbled upon this Burroughs C 3207 calculator with several issues for a price that was too good to pass up. And it’s a vintage 14 digit Nixie tube calculator Built in late 1969.
