Nice find! wow, pretty long code 
I suppose it is fast and snappy due to machine code routines. The sprite could be interesting to see it is somehow mixed with the background "on the fly", or just hides the character behind it.
PS: interestingely just in the last weeks I made some mockups, how a GUI would look like with a small modification of the PETSCII charset. (certainly it needs further finetuning eg. drawing routine able to realize the font behind it, etc, it is the minimal level change of fontset)
The style is mainly from Amstrad PCW16 GUI "Rosanne", that was a Z80 based strange machine (thanks to Litwr who showed it to me!)
