The NE-Z8000 is a Brazilian homebuilt computer clone of the Sinclair ZX81, introduced in late 1982 by Prológica's subsidiary, the monthly magazine Nova Eletrônica.[1][2][3][4][5][6][7]
General Information
The NE-Z8000 computer is based around a Z80A CPU clocked at 3.6 MHz with 1KB of RAM[8] (expandable to 16 KB[3][1][8]). The 8KB ROM comes with a built-in Sinclair BASIC interpreter.[8]
The machine has four plugs on the back (9V DC, EAR, MIC and TV), and an exposed part of the circuit board where you can connect extra equipment.[4][1]
The video connector cable is about 120 cm long and connects the TV plug to a regular PAL-M television, outputting a monochrome image on VHF channel 2 or 3.[1] The EAR and MIC plugs allow to connect a cassette tape recorder for data storage, supporting a rate of 300 Baud.[1]
It has no switch; to turn it on, you simply plug it into the power supply. A power supply provides 9V DC power usable by the machine.[1][8]
The NE-Z8000 is considered rare,[7] and in 2013 it could be auctioned by as much as R$1000.[9]
