Its dimensions were 22 x 28 cm, and it had a RCA 1802 processor; along with a crystal clock operating at 1.76 MHz (3.521280 MHz divided by 2). It had 2 KB (2048 bytes) of RAM, which could be expanded to 4 KB on board, and 32 KB via an expansion slot. Its 5V DC CDP18S023 power supply had an output of 600 mA. I/O ports could be added to connect to sensors, interface relays, an ASCII keyboard, or a printer.
