I got the logic analyzer from ProBoard today. This is the $199 24 channel
device discussed here in the Piclist before. I ordered the 8K sample
upgrade ($39) and they threw in for free an extruded aluminium box (listed
as a $39 value).

My impressions: basically it's exactly as advertised - it is well made, uses
pretty standard components (the memory is not FIFO chips, but 20ns 6264
skinny-dips). The on-board clock is a 50MHz canned oscillator in a socket.

I did not get (and they told me this in advance) the 115200 baud feature - this
is apparently coming imminently - they did supply an extra crystal apparently
to replace the 8051's current crystal for the new baud rate when I get the
new software. Printed doco is sketchy, but there is a much more extensive
read.me file on the disk, along with 3 different user interfaces.

I've only briefly played with it, but it came up with no trouble, and appears
to do just what it's supposed to. The user interface is VGA graphics, but
ran happily in a full-screen DOS box under Win95 (haven't tried it under NT
'cos my NT machine has no spare serial ports).

A couple of gripes; the case is of limited value since with the board in
it, you can't readily get at the reset button (== terminate capture) nor
can you get at the external clock input (it's just a pad on the board - you
have to solder a connector to it). There appears to be provision for pre-
rather than post-trigger sampling, but the doco says it's not a supported
feature yet.

Overall I'd say that it's good value for money, and if, like me, you have
occasional use for logic analyzer but can't justify spending $000's on
one, this would be a good buy.
