This Saudi Arabic Spectrum ROM, named ARAB RAM is not an officially commissioned ROM. It was made by Ramez Halaby & Co. of Jeddah, operating under the name of Autoram Computer, which was known for add-ons to convert ZX81’s and Spectrums into Arabic language machines. An example can be seen here.
The Arabic copyright reads:
© اوتورام كمبيوتر
© Autoram Computer
