Summary[edit]
Description7-SEG (3630191549).jpg | This is a close-up shot of the screen on a Unitrex 801D pocket calculator. The calculator is quite old (I happened across it in a thrift shop), but I couldn't find very much information about it on the Internet. (If anyone knows its history, please let me know in the comments.) I took this photograph for a contest held by the engineering department of my university. One of the categories was "electronics"; the VFD display on this model caught my eye, as they haven't been used on calculators for a long time, due to their power requirements and size. |
