HP Logic Analyzer Inverse Assemblers
deanclaxton:
Gerbers attached for the 65C02 adapter, but I havent built/tested this yet. I'll update this post once I know its working ok - I'll slip in a few of these boards with my next order. This can be used with Phils inverse assembler (I'll have to get that running on the 16902).
The order of the STAT signals is correct for his inverse assembler. I designed and built a similar adapter for the 40 pin probes with all the termination parts on the adapter. This will be much faster to assemble!

16902A arrived in one piece, which was pretty amazing given how it was packed |O One small crack in the bezel unfortunately, but minor.
Otherwise the unit is in mint condition and the 3 x E5382A probe sets look unused.
I've ordered a E5378A from ebay so that I'll be able to build/use my adapter.
The analyzer was joined to a domain and the seller had no idea of the password, but I was able to use a recovery tool to reset it and log in.
I ran the self test on the 2 x 16950A cards and they both passed with no issues. I guess I should remove the glue under the stiffeners - assuming these cards would have used the same awful corrosive stuff - preventative maintenance?
TO DO :
* Upgrade the 16950A's to 64M aquisition memory (a software unlock) DONE
* Build the 65C02 adapter
* Get Phil's 6502 Inverse Assembler running on it

Sounds like everything is in great shape! I found the ebay listing and even the E5382A's look like they're perfect. It's even more rare to find them with all the accessories.
I don't have any 169xx series chassis or cards, so I don't know if the corrosion issue was recognized and/or fixed at that point. Maybe someone who has them can comment.
Failing that, you could look closely with a microscope around each runner for any signs of green fuzz. If you see anything, pull them all off. Here's a good page that Keith put together:
https://www.techtravels.org/2019/12/corrosion-near-underneath-hp-logic-analyzer-module-plastic-runners/
I'll emphasize what's already on that page that heat is your friend.
I usually discourage knee-jerk prophylactic maintenance (like re-capping everything in sight), but in this case if it was me I'd pull all the runners off anyway. Why wait to discover the hard way that HPAK didn't really address the problem yet.
Unlike Keith, I did not put the runners back on.

Awesome - thanks :) I'll be sure to check the boards over this weekend. The E5382A's appear to be unused - all 3. Manuals are still shrinkwrapped, both for the analyzer and the probe kits. I found an additional cable inside the pouch which appears to be something to do with the Agilient N4220B PCI Express Packet Analysis Probe. I think it goes from the PCI Express slot to the N4220B unit. Seems the eBay seller is selling one. EDIT: Made an offer on it - probably never use it but who knows.

Thanks to a very helpful forum member, the 2 x 16950A's are now upgraded to 64M! :-+
