The so-called Fast Print or Killer Poke

[wte]

I have a question about the so-called Fast Print or Killer Poke for early PET / CBM Computers.

Info: http://6502.org/users/andre/petindex/poke.html

Code Select Expand

POKE 59458,PEEK(59458)OR 32

This poke speeds up early PETs (old boards) but is a problem for machines with a CRTC (newer boards).

As I want to write a little multi platform BASIC programm I need a peek to distinguish between old and new boards. So that I'm able to poke or not to poke. I've read that there had been a solution for this problem long time ago in an US computer magazine. Is there anyone who can remember this?
