This TI-2550-IV was manufactured
in February 1979 by Texas Instruments in Italy (week 08 year 1979). |
The printed circuit board (PCB) of the
TI-2550-IV shows just the VF-Display and keyboard. |
The backside
of the PCB sports a clean layout but hosts three different Integrated Circuits. |
The three Integrated Circuits (ICs): TMC1981, TMC0999 and BP51C. |
