HP 11C

The Hewlett Packard HP-11C was a mid range scientific programmable calculator. It included two new features: a built-in random number generator and a backspace key that allowed numbers to be corrected a digit at a time.

The HP-11C had 63 lines of permanent program space. As programs grew larger than 63 lines, registers were converted into additional program space starting at R.9 and ending at R0. There were 20 registers (not including the I register) and each register converted into 7 lines of program space. Thus with all registers (except I) converted to program space, there were 203 program lines.
