Like the 75C, the 71B was a handheld, single-line BASIC computer. The 71B was smaller and less expensive than the 75C. The 71B had a 64K operating system and 17.5K user memory. It came with four ports for adding ROM-based programs or additional user memory. The 71B offered an optional magnetic card reader and optional HP-IL interface. With the optional card reader, the 71B used the same magnetic cards as the HP-75. However, programs written for one machine could not be used on with the other, because the computers had different versions of BASIC.
71 and 75 handheld computers are very reliable. As of 2013, all six or seven units we have at the museum are in working order.
Jeff Garnier has created a very clever USB interface to connect HP-IL computers to modern PCs. PIL-Box.^ TOP
