Changing the clock frequency slightly (PDP-11)?

Rumor has it that Charles may have mentioned these words:

I are a dumby when it comes to PDPs, but if you're worried about 
overclocking, Mouser has 26Mhz oscillators on the shelf - it's closer than 
25.x Mhz.

Page 665 in the catalog, IIRC. Their search utility is somewhat OK, too, at 
least to narrow down a page or two of the catalog, then you can view each 
page as a PDF. Not a bad system, really.

[[ A page or two before that, they have Fox custom oscillators as well - I 
don't know if they're a better price than Digikey or not... ]]

As always, just a satisfied customer; no other affiliations. ;-)

HTH,
