The AS-1000 was a Brazilian clone of the Sinclair ZX81 introduced by Engebrás Eletrônica e Informática Ltda in October 1983.[1] [2] [3] [4] [5] [6] [7] [8] The main differences regarding the ZX81 are the internal power supply and larger RAM. The machine had an initial retail price of Cr$ 195 000.
The computer came with 16 KB of RAM, but could be fitted with 32 or 48. There were 8KB of ROM and a 40-key membrane keyboard.[9] A regular TV set was used as monitor, with the computer displaying 32 x 22 text characters in monochrome. By using semigraphic characters, it was possible to simulate a 64 x 44 resolution display.
There was one expansion slot at the back of the machine, with the TV RF-out, audio in/out and joystick ports located at the side.[10] Storage was by means of audio cassette, with a data transfer speed of 300 bauds.
