I've got the need to connect a logic analyzer to a socketed 84-pin PLCC
IC. The test clips I'm familiar with won't attach properly because they
expect a soldered chip instead.
Besides removing the socket and resoldering the IC directly to the PCB
and using a traditional test clip (which are affordable), are there any
other plug-and-play solutions?
I've found these
http://www.emulation.com/catalog/off-the-shelf_solutions/logic_analyzer-sco…
http://www.emulation.com/cgi-cfm/insert_quantity.cfm?part_number=BC4-84-PCC…
($308)
and
http://www.logicalsys.com/painfo-vpasp-vb.asp?adapter=pa84-pp ($185 US)
which seem pretty darn cool, but also pretty darn expensive.
The PCB is almost 30 years old, for whatever that's worth.
Thanks,
Keith

It depends on how much you want to wait, and/or how much you want to
spend/work
You can do an adapter, but it is some trouble and work
Or you can wait it appear on Ebay :o)

I could justify a $75 price tag maybe.... I suppose I could set up some ebay alerts on
those part numbers but I have a feeling it would take awhile to show up.
Building one seems hard and might net me little discount after I'm said and done.
Thanks

While realizing that I'm both top posting and replying to myself, I'm a lucky man
today. I found two of the adapters new in box for about $100 total on craigslist. They are
already on their way. I'm lucky!!

Seems like an unlikely item to turn up on craigslist just when you
happen to need one. Did you find it locally or were you searching
locations everywhere?

Glen,
Yes, indeed an unlikely item. I envisioned waiting months and/or years
before an affordable one came around.
I actually just googled the part numbers and I saw a craigslist post
from September that was of course expired. I said,
"darn, so close."
Then I figured that it might be a hard time to sell
these items, so I
navigated to the city page and searched. Voila. Same guy reposted the offer.
Emailed him, exchanged info, did some quick background checks to make
sure the name/address/phone number/email/paypal matched, made sense,
etc. And then pre-paid via paypal. Of course I was paranoid with using CL.
The craiglist was not from my city.... it wasn't local, but instead a
few states away. I'm not sure the city mattered.......the fact that it
was in the US, reachable by relatively cheap mail services, etc.....
I never really considered CL a valuable source for this type of
stuff.....maybe I was wrong. I was definitely wrong this time.
And lucky.
Thanks
Keith
