*With optional Microsoft BASIC ROM

rl-h1400.jpg (37846 bytes)The RL-H1400 is the second, 4 kB member of Panasonic's family of so-called HHCs, or Hand Held Computers. Functionally identical to the RL-H1800, it only has half the memory.

These machines were often sold in preconfigured form, in application-specific OEM packages. The RL-H1400 I have contains a pair of ROM chips with an insurance application. All RL-H series machines can be used stand-alone as a four-function calculator; however, programmability was only possible through the use of an optional ROM version of Microsoft BASIC. (Presumably other programming tools were also available, including assembly language tools.)
