The Netronics ELF II was an early microcomputer trainer kit featuring the RCA 1802 microprocessor, 256 bytes of RAM, DMA-based bitmap graphics, hexadecimal keypad, two-digit hexadecimal LED display, a single "Q" LED, and 5 expansion slots.

The video terminal card fits underneath the keyboard in the optional case to form a stand-alone video terminal sending and receiving serial ASCII.

Either configuration could be interfaced to the ELF II through the Giant Board.

The terminal kits were also marketed independently of the ELF II.

Improvements on its predecessor included an etched PCB, a hexadecimal keypad instead of toggle switches for program entry, the RCA CDP1861 Pixie-graphics chip, and the 5 slot 86-line bus for expansion cards.
