Very old computer...

[gibant1]

my dad had two super old comps. these were the oldest things I've ever seen! one was new in the box he never used and we were playing with it.
It was a texas Instruments computer. It was made before they had Hard disks, Floppy disks, Dos, etc.
It only used one simple programming language. and you'd never have to worry about corruption. when you ran into a problem, just turn it off and back on!

Is it the Ti-99? I had one of these, the games were brilliant at the time (everthing else was dire!.

Have a look.
