I think some values for LPT must be fixed:
C000: character map
C400: font data ($C400/128 = $188)

One hint: if you use EXOS LPT then you can use 27 character lines + status line = 28 total lines.

cool effect. I use this in my demo, but with rotating dots: https://youtu.be/5Eg14WLJmEk?t=329
try it with mixing this shade effect with some rotating.
Vigyázat! Szektás vagyok! :)

Same effect with Ork used at ZX Spectrum at demo what name I forgot. I am afraid tile data over 256 bytes.

If you have time, you can try it with 4 colour character mode with half horizontal resolution also, I think it would be also very impressive :)

One hint for getting bit more CPU and speed, if you set port 0bfh to 0ch then waits are eliminated :)
