The system was originally purchased by someone who didn't know what they were doing. They bought an accounting system, and didn't realise it wasnt windows based.
It probably would have been cheaper to buy another accounting system.
So the bought an AS/400 to run it on, and bought emulator cards for everyone in the office, and ran a second star of Cat5, and paid a ridiculous amount for the whole thing. It gives them roughly quickbooks-level functionality.
Probably a vertical-market type app? Most mainstream accounting apps for the platform are quite a bit more sophisticated. But with vertical-market, it's always a crap-shoot.
My main complaints with the platform are:
1. Text-based everything (user admin, etc)
Outdated, or at least no longer mandatory.
This is what's current. Of course, most modern OSes are text based with a GUI slapped on so in that respect OS/400 is hardly different from Windows, Linux, *nix, OS X, OS/390, OS/2, etc. And old-timers like me prefer the text interface as it's way more efficient than any GUI. The GUI has it's place, but I can do things much faster in text mode. Also, the same commands you enter in text mode can be programmed/scripted to run later. Try that in a Windows GUI.
For the end-user interface, there are also a number of programs from both IBM and others that will provide a graphical presentation layer without having to re-code the underlying apps.
2. Funky port-specific hubs, etc.
Twinax-to-twisted pair. Again, outdated since TCP over LAN is the only supported client connectivity scheme on current releases. I'll note that IBM seldom strands it's customers and has even created an IP stack that'll run over the old Twinax cable infrastructure, making it another LAN topology.
The twinax infrastructure predated most LANs, BTW. The need for co-existence of cabling ended several years ago. Twinax still has advantages, though, like 1000 foot runs between hops w/o a repeater, data prioritization, heavy shielding, and no hubs. (The last two are n/a if using the UTP converters like you were) Also, since the basic format is a daisy-chain, you didn't necessarily have to have a separate star cable environment. Very handy when several devices in the same office or just the same vicinity need to be connected.
