NTSC/PAL/SECAM & PERITEL?
This "Star" Arabic 65XE, also known as Atari 65XEN (from the motherboard) is a little jewel is a collection. It's hard to figure out how many of them survived, but they are extremely difficult to find in working condition in Europe. I'm not even talking about the original box and owner's manual.
Inside the machine
The "Self-Test", with the Arabic character set
Playing the rare French "Des chiffres et des lettres" cartridge, with the Arabic character set
Using "PEEK" instructions in BASIC to find out about the OS, Basic and NTSC/PAL versions.
For your information, the results are:
PEEK(53268) = 1 [PAL/SECAM]
PEEK(65528) = 177 [Not a 400/800]
PEEK(65527) = 59 [XL OS Rev. 3B, 1987-07-21, Arabic Atari 65XE Najm (all)]
PEEK(43234) = 234 [Atari BASIC Rev. C]
