Hi Tim,

I have one and I like it (read my review in Nuts and Volts a few months
back). I use it at 20MHz all the time. There are a few "quirks" you have
to get used to:

1) It takes a long time to transfer all the registers at 56kbaud or
whatever it is using. To "fix" this they let you download just some
registers (the really important ones + anything in a watch window).
That's great until you forget and wonder why your registers aren't
changing (they are, you just aren't looking). I wish they'd gray the
registers you aren't looking at or something.

2) Breakpoints happen after the instruction they are on occurs. This
takes a little getting used to.

3) There is no "step over". It is a shame they can't notice a call
instruction and ONLY for the call instruction set a breakpoint on the
next line. This would look like step over but would not break the skip
instructions.

Still well worth the $100 or so. I know that Transdata has a parallel
port version. That would probably be faster to download the registers.
Once you get used to the idiosyncrasies it is smooth sailing.
