Does anyone have information regarding modifying a pdp11/93 cpu to run
at 20Mhz? It's been mentioned on a couple of web pages, but I can't
seem to find details.
Thanks!

There isn't much of detail to tell, simply replace the 18Mhz Xtal
against a 20Mhz one, but be warned, the CPU isn't the only limiting
factor for the speed, the Gate Arrays and the FPU are also involved.
Maybe you toast them while overclocking..
I've changed th 15Mhz Xtal from an 11/73 CPU to 18Mhz to get a 11/83..
