'Ey! What'cho got 'gainst punch cards?
Never used the Power Samas 36? column cards, just the plain boring 80's.
Nope, just the normal 80 column punchs. All IBM, y'know.
Was an excellent hand puncher. Could easily read cards by holding them up to the light and could fill-in the wrongly punched hole to avoid having to re-punch the entire card.
Never heard of a hand puncher. All I ever used or saw were desk-sized machines.
The read up on Grace Hopper and how she 'discovered' an unknown opcode when a mispunch she glued in with nail polish. They used hand punchers a lot on her programming team.
H-1250, H-120, H-L61, H-L66, H-L64, DPS 8 etc. + BBC Micro B & B+
To catch that error, it took the lab assistant, the *only* time in my school career I needed one, to read the actual holes.
Nasty.
