I discovered a fault in Sakhr AX-170 firmware. It's in the calendar!
Turn Sakhr AX-170 on. Choose the calendar (option 1). Now follow these steps:
1- Press SPACEBAR
2- Press RETURN
3- Press "1"
4- Press RETURN
5- Press "1"
6- Press RETURN
7- Press "1"
8- Press ESC
9- Press ESC
10- Press SPACEBAR

FAULT!! ????????????????

Note:
I think the fault is in all MSX1 calendar firmware. What I'm sure of is that this fault doesn't appear in MSX2 calendar.
Enjoy and explore more. You might find interesting things about that.

There's also a error on MSX2 Arabic computers, it's about the date, the year begins always with 1, never with 2. So, 2016 becomes 1916.

and 11-Press ESC

It gives Overflow

List gives line 51161 of the integrated program, obviously written in MSX-BASIC

But the correct using is 8 - Press RETURN

Can't you extract the BASIC listing of it?!

I think it can be made with an hexadecimal editor.

Here in my country we do not have electricity since March, 26, 2015 due to Saudi led-coalition's aggression on my country Yemen. So I can't use my real MSX or my PC, and doing that using my phone is not easy. So why don't you try to do it?! I presume that you have a hexadecimal editor for PC such as Hiew32 or better, haven't you?!

Can this be done in BlueMsx too? I failed to replicate this. Maybe I missed something.

Yes, as I've tested in blueMSX. Sometimes, step 11 needs to be done twice (and before that, the software 'hangs' on step 10).

Note:
This fault does not occur on MSX2 calendar software. That's what I discovered.
