Which features did this model have? It's not too easy to find information about models and sub-models of 5250 terminals today. Hmm.
The 3487-HC was (and presumably is, since I'm sure there are still
specimens in working order) a 132-column color terminal (corresponding
to the 3477-FC) with all the usual InfoWindow II features; column
separators could be turned off; it could use a mouse (but only a genuine
IBM mouse). The same iconic status line as all InfoWindow and InfoWindow
II terminals (and some others, e.g., 3180). Up to two display sessions
("sides") and a printer session (a 3488 has four sides and a printer
session, but requires a separate monitor). Double-pigtail-style
auto-terminating Twinax connector.
Both of the terminals we had (the other being a 3180) when I was hired
are long-gone (the 3180 failed in a rather spectacular fashion:
something, probably the flyback transformer, shorted out, blowing a
fuse. When I replaced the fuse and applied power, the fuse didn't just
blow; it exploded.) We now have a 3477-FA (monochrome InfoWindow with
amber screen; it was cheaper than green or color, and amber is actually
the easiest on the eyes), a 3488 (as I said, InfoWindow II with 4 sides,
requiring a separate monitor), and an Affirmative Twinax Yestation. (2
sides, requiring a separate monitor, but all the standard EBCDIC
codepages were built in, unlike any IBM terminals). All of them were
purchased used (and I don't think Affirmative was still making any
Twinax models by the time we got our Yestation).
The only CRTs still in use here are the ones on the terminals: I have
het to find an LCD monitor that plays well with the 3488 or the Yestation.
