Calculator Wars at your School

[Alejandro Paz(Germany)]

I used to bring aHP-12C to school when I was in 7th grade, some kids had casios or sharps. Later, when I was in 4th year of middle school, in '91 I brought a 28 and a 48 I to school. A couple classmates were so impressed that they bought themselves one a 28 and two others a 48. They were extremely expensive back then. I couldn't afford them myself but my father got them from work, discarded calcs that couldn't be repaired (he worked at HP), the 28 didn't have any problems besides myself opening it and gluing it back together, would lose its memory every now and then. The 48 was missing some vertical lines on the display, a common fault then. Some had graphing casios. And were like mine graphs faster... yeah maybe it also had 96 pixels across instead of 131 .
