Operation
Six of the seven 8-bit registers could operate as 8-bit or form three pairs of 16-bit registers.
Each instruction was 8 bits (including register addresses), and most of them were followed by one or two data bytes, which could be direct data (factor), main memory address, or gate address. Most instructions performed single-byte operations; in two-factor instructions, the second factor could be direct data, the contents of another 8-bit register, or a main memory byte addressed by a register pair (16 bits!). Data transfer was handled by MOV instructions, which made up a quarter of the entire instruction set.
The calculator could perform fixed-point addition and subtraction of binary and decimal numbers with 8-bit data; multiplication, division, and floating-point operations had to be programmed separately.

Historical curiosities
The hardware can be built modularly, from simple systems with a few cards to complex systems.
An important aspect in developing the machine was to create an acceptable service/price ratio.
