Burn in Tested.

AMD 2901 bit-slice processor family includes 2901
and 2903 4-bit microprocessors slices, 2909 and
2911 microprogram sequencers, 2910 microprogram
controller and other support chips. The 2901
processor consists of 16 4-bit registers, 4-bit
ALU and associated decoding/multiplexing
circuits. The ALU accepts 9-bit microinstructions
that specify source operands, ALU function and
the destination register. The 2901 ALU can
perform 8 different functions (they are encoded
into 3 bits within the microinstruction):
addition, subtraction and logic operations.
Multiple 2901 bit-slice processors could be
combined together to build microprocessors with
any data width (in 4 bits increments).
