The mentioned slowdown should only occur each time the contents of the screen buffer is displayed.

How would I use Celtic III for my needs...?
Wouldn't it screw up my xLIB commands?

If Celtic III works as it should, it's as simple as replace, install, and forget. I would, however, encourage you to find out whether or not Celtic III will actually work for your needs, as xLIB compatibility isn't perfect.

@calcdude84se: You said something about CalcSys's port monitor. Could you explain this process?
How would you edit the values of the port and make it work?
I'll repeat WikiTI. Port 29h will add a delay of so many clock cycles to any instructions involving the LCD, which is the port value divided by 4 (i.e. ignoring bits 0 and 1). See if it works when the port has different values (make sure bits 0 and 1 are 0 on an 83+SE, 1 on an 84+(SE)). So, start with 0F, then try 13, which you get by adding 4, then 17, 1B, 1F, 23, 27, 2B... And so on. What Brandon fears is that even when the port contains FF the delay (63 clock cycles) won't be enough. It's worth a try, though

I don't think he actually knows how to change the value in the ports.

To change the ports, download Calcsys. Send it to your calculator and run it. Then go to port moniter (3), and scroll until you find port 29h. Then press enter to change the value and do what calcdude84se said. The values are in hexadecimal.

Oh, that's what he wanted to know. Oops. Yeah, thepenguin77 is right. Btw, you can scroll 5 (I think that's about right) ports at a time  by pressing left and right rather than up and down.

Nice to hear that it works. Glad to help! Though it might not be useful, what's the smallest value for port 29h that worked?
