That said I've pushed the clock on 11/23 board

clock was wound up to 25mhz using a external source. I started seeing
errors above 18mhz but they were random, seems bus timing and memory
timing all had to be happy and I was pushing the margins. I eventually
put in a clock module for 15.8mhz as I had one. For that it was a modest
speed up as the 11/23 is slower to start with.
Hey! I too overclocked an 11/23. My friend Ernie and I were hanging
out late one night hacking on one of his systems, and I had brought a
spare 11/23 CPU along for this purpose. We got it up to 16MHz; we
didn't take it any higher than that. I'm amazed to hear that you got it
up to 25MHz!!
