The romcall does not delay x many clocks, it simply reads a port until it indicates the LCD isn't busy.  You can get a rough estimate but I would guess it varies slightly from machine to machine and depending on batteries and other variables.

Exactly how many clocks do the 83, 83+ and 83 SE require between writes to the LCD ports?
