Rockwell-Anita 1211 SL
Rockwell Anita 1211 SL.
Power supply - AC mains.
Display is 12 digits, amber gas-discharge 'Pandicon'.
4-function, %, memory.
Integrated circuit - Rockwell A4350PB, here date coded 1975 week 16, and 34 discrete transistors.
220 mm x 168 mm x 50 mm (8.75" x 6.6" x 2").
"Made in England, Electronics Group, Rockwell International. Distributed in UK by Sumlock Anita Ltd.".
The circuit board is marked:
"1211 MAIN BOARD-PANDICON
1976 CD ISS 2 YBU 3052"
So the display appears to be a 'Pandicon' type.
The 'SL' in the model name stands for Slim Line.
With the casing opened and showing the circuit board, showing the Pandicon display, the Rockwell A1150PB integrated circuit and many other components including 34 discrete transistors.
Note that this model is very similar to a slightly earlier model which is labelled Rockwell Anita 1211, without the 'SL' designation, with circuit board marked:
"1211 MAIN BOARD-PANAPLEX
2028 CD ISS 1 TBU 3051"
That model has a 'Panaplex II' display and other electronic detail differences.
