Hollerith or IBM?

We found something older than our Siemens Telephonysystem from 1922.

It is a manual card punch from the Deutsche Hollerith Maschinen Gesellschaft M.B.H. Berlin from 1920.

In grades 5-7, I started learning to program in #BASIC on Atari 400, #Atari800, and TRS-80 (and got an unfortunate lesson in their differences).

In grade 12: UCSD #Pascal on #Apple2 e

In college: #COBOL on a CDC Cyber, #Fortran on an IBM 3081, Borland #turboPascal
on PCs with MS-DOS, #C on a Sequent Balance and IBM #rs6000, and #C++ on PCs running Windows

Along the way, I got familiar with a #hexKeypad and once used a #cardPunch. (I made some hardware too.)

I'm still learning new stuff...
