Hey Rob (and anyone else sniffing signals),
I've been using a USB logic analyzer from Saleae (
)
for years now and the software is really good. Way cheaper than a
standalone unit. I'm unsure if the inputs can handle more than 5v but you
could throw a divider network in front and try it.
Also there's the Digilent Analog Discovery (
) which does the same stuff but I
can't vouch for the software as I've never used it. Inputs can handle
+/-20v apparently.

I have a 350 and 380. Neither work. The 380 is reporting a possible

The 380 has memory on the motherboard, and a model-specific
daughtercard for expansion memory.
It seems reasonable that the Pro bus (I/O card) expansion memory should
work in both models, but I don't have any to try that.
If you have a 380 complaining about memory and it has a Pro bus memory
card installed, I'd suggest removing that card to see if it's happy with
just the
stock motherboard memory.

Just reading your reply again. Are you saying it has enough memory on the
board, without using a daughter board? I did see lots of memory on the main
board, but assumed it was video memory. I did try removing the daughter
board altogether at one point, but it still didn't work. :-(
I wish I had a logic analyser.
