the #HP-12C #calculators bug
on 02024-09-13More about the #HP-12C #calculators bug: “The company HP licensed their calculator production to accidentally shipped a run of units with buggy firmware. Most have been captured and flashed with corrected firmware. Some distributors were unwilling to return their calculators for rework, which is how these ended up in the hands of customers. Anyone with a buggy calculator should contact HP calculator support for a replacement.”
on 02024-09-13Some new firmware versions on #HP-12C #calculators are returning badly incorrect results on certain financial calculations (TVV and IRR); “HP” has apparently reverted to old firmware versions because of this.

This “GHLBD” brand four-function calculator has a gigabyte of RAM, a 32-bit quad-core Allwinner A50 507 CPU (1512MHz Cortex-A7), 3+ gigs of Flash, and a 2700mAh LiPo battery. So this wild hacker installed bunch of #retrocomputing N64 #games in an emulator. Doom 3 runs at 16–32 fps.
