Grab Calcsys and send it to your calc, then go into the port monitor and go over to '10', hit enter and then type in the values to test with. This is how I did it, anyway.

Yeah, that's about the best way to do it, unless you really like writing ASM programs :P

wow, just looked at the pics, didn't realize it not only flipped vertically, but horizontally as well.
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

Ok, so I'm still not quite sure what to do. I have Calcsys on my calculator, went to Port Monitor and went to port 10 (says at the bottom that it is LCD Instr but not sure what that means). After that I'm not exactly sure what to do. Like I push enter and see something that says "Output:" and a little weird token thing. Not sure what I type in there.

Ok, so I take that back. I figured it out. My screen flips to like calcdude84se's. The last part of my serial is P-0108J.

It works for me too. Serial is S-0506K. I also found how to shift the screen vertically while I was at high school, it was the same port number, but I didn't knew about flipping the screen...

Edit: Found the numbers: it's from $40 to $7F, $40 is the normal position, $41 causes the screen to shift one pixel up, $48 is one line of text up (since 8 pixels are one line), the first line becomes the last line, and so on.

I believe all the others values causes blue lines of death, that's why I didn't gone below $40...

Yay, two others who've been able to duplicate it!
* calcdude feels less special now :P
As for the BLOD's, commands in the range $18-$1F cause them. Other commands do stuff like set the position on the LCD to read from/write to.

Nice find!  So that's the source of these mysterious "glitches" like the one that killed Nyarr. ;D

edit:  Tried!  I love it!  It works on my calc, 2635016775 P-0509M.  This is so much fun!

How do I put it back to normal? :P

I thought Nyaar RPG died due to {AP} having lost motivation on the battle engine? I don't remember him getting mem clears on it

Something like this happened to him.  I just can't find the topic to site this source. =/

What, BLOD's or vertical shifting?
Vertically shifting the screen is documented and the OS will fix it every time you turn the calc off and back on.
As for BLOD's, pull the battery. Quickly.
Also, it's $40-$7F, not $7E :P

calcdude84se: yes I meant $7F, my keyboard slipped and didn't noticed the error. Fixing my post now.

But it could be nice for a vertically scrolling picture, right?

I love how the flipping trick doesn't do that so you can easily trick your friends.

Alright, a RAM Clear didn't even fix the flipping trick.  I see a lot of fun in my future. :P
