Brown 2225B? - Dave Frederickson - 06-25-2016 02:15 PM
Saw this brown 2225B on eBay, model HP 82190A.

I can find no reference to 82190A on the web. Anybody know anything about it?

Dave,
I have not found anything on the Internet either.
I also found nothing in the HP Catalogs (from 1984 to 1990).
My HP Catalogs PDF are not indexed, so I did a visual survey of the printers section.

I thought it might be a component of a larger system, like the HP 5890A Gas Chromatograph, which has HP-IL. The model numbers both end in "90A" which may not simply be a coincidence.
Edit: This 5890A system includes a ThinkJet, unfortunately it's not pictured.

I believe this is exactly correct. In the 80's HP sold suites of products as a larger system (like the example GC system you mention) and often renumbered the 'standard' components to prevent folks from knowing they could replace components with easy to find off the shelf parts (in this case a 2225B), but there were also cases where these renumbered components had technical modifications tailored for the type of system they were used in.
As an example, this 'special' ThinkJet may have used a non-standard Character set, including special graphics characters used in the GC application, allowing them to build this special product out of nearly standard components
