anyone have a 74HC245 laying around?
I thought I might build (or prompt someone to build) a logic analyzer using the PC's parallel port Rather than unsolder the imager from a pv2 (or try to remember where my 6410 camera is), I thought it would be simpler to connect a logic analyzer to the imager pins on an FF2 or FF3. I could then hopefully match the logic pattern with http://cexx.org/dakota/pv2cmos.htm to identify the lines names. Then comes the really easy part of writing values to suspected hardware registers all the imager lines are matched up with a hardware register. I doubt free samples of the 74HC245 are available since it is probably fairly common and cheap...much cheaper than the postage to mail it.

that sounds like a pretty good idea. if i were u, id definitely use the image pins on an FF3

How about one already in a DB25 shell w/ cable? Actually a SN74LS245N. If you can use it, PM me :)

If you want to get REALLY serious about logic analyzing these things, I can fix you up with a fully loaded HP 16500B analyzer for a decent price... depending upon what boards you want would run around $250-$600. New price was around $30K-$100K. Low end would be a mainframe and 16550 analyzer card/pods/grabbers. High end has 250 MHz-1GS/sec digital scope card, deep memory analyzer card, pattern gen, 1GHz timing analyzer, etc. If you want to get REALLY INSANELY serious, there is my 16700A and 16702B... These guys run Unix (HP/UX) and have a built in web server so you can control them from afar. They also have Netscape so you can surf the web from your o'scope.

The main problem I have (besides a SERIOUS lack of time) is connecting to the camera. I have SMD grabber clips, but don't think they can grab onto anything useful in the camera (but it's been a while since I had one open). I know that TSOPs are too small to grab (and TSOP -*test*-('") clips are $600+, right Catepillar?). As far as the 16700 series analyzers, they have a built in web server. They can be controlled from anywhere in the known universe. The 16700 has a PC kbd/mouse/VGA monitor interface. 16702B adds a spiffy touch screen LCD. 16500's have a built in Sony Trinitron CRT with IR LED matrix touch screen. Cabling from the device under -*test*-('") to the analyzer is about 3-4 feet long.
