I hope you appreciate this <G>.  I had to clean off a space from my taxes
(fun day today 8-( NOT) to plug it in and see.

It gave clocks up to 20 MHz for a '5x.

For a '62-'74-type-chip (74-ME installed) it topped out at 11.0592.  Same
with a '711-ME installed.

I didn't check the '84 because I'd have to remove the '711 which is what
I'm working with right now - please forgive.

You can always try asking Parallax or Tech-Tools to provide a specific
frequency.  I did at one point and they sent a table to include my
frequency.  Only problem is, they didn't make that part of the release
table, so as soon as I upgraded my PDE, the new speed disappeared.

There are probably physics limitations on what they can give for
frequencies, though.
