I held off quite a while before I owned any sort of computer. There was always something at work but I waited for home hardware to get cheap. I think my first machine was some home brew closeout 8086 MB and two big bad 360k floppies. Too long ago to fully remember. Low rez monochrome orange crt monitor of course.
I'm retired with plenty of time to waste so I did have a bit of fun researching early computing hardware. "Computer" was originally a job description, referring to those rows of slide-rule clad soldier wives in large buildings calculating bullet trajectories. Distributed processing for sure.
Eniac is sometimes referred to as the first electronic computer but it didn't have anything to do with currently accepted computer architecture. That seemed to be developed later in the UK. In modern day terms Eniac would be considered a very small, slow and weak FPGA. It worked in base 10 instead of binary because that is what those other rows of "computers" did. Hundreds of kW worth on vacuum tube based base 10 shift registers, adjustable clocks, analog integrators and a bit of A-D mixed in. It appeared to process only small portions of a task at a time, needing to be "re-programmed" with telephone patch cords before the next segment. Much like those other rows of "computers". It seemed to be half modeled after the "computor" job description. It likely was also modeled after mechanical adding machines of the era and their base 10 shift registers.
