We used it for a Clipper based management application.
My first task was bringing back to life our school labs network, so that we could use it for that application, got to love those coaxial cable terminators.
We are buying a new iSeries and the IBM person was very specific that the terminal we have in the server room is NOT supported anymore without some weird interface board. I was kind of sad at the thought. Even sadder knowing I'm going have to load IBM's client access software on some poor PC.
I worked for an egovernment company several years ago. A state (county?) agency built a service with us, and wouldn't expose the actual database to us, just an SNA supporting interface. We were essentially scraping the data. Messy, unsanitised data. I really didn't envy the developer who looked after that particular application.
I'm pretty sure what we are getting is a renamed Client Access on a small PC we need to set in the server room. Client Access is legendary for how bad it is from installing to using. I would rather have the terminal.
I used Summer87, 5.x in school assignments and early contract work, also got a copy of Visual Objects, but ended up trying to do the app in VB instead.
