The machine was also designed from the outset to allow it to scale across a wide variety of needs. The system included 64 hardware channels that could be connected to peripherals of any sort and could be supplied with a wide variety of core memory sizes. In other ways the machine was fairly similar to the ReserVec's Gemini machine, using a 24-bit word with a 25th-bit for parity checking and a simple machine language. One change was the lack of a memory drum, as the advances in core allowed them to replace the drum entirely.
