Re: Speaking of 'doohickeys' . . .

ECB = Extended Character Buffer.

The ECB holds the display attributes that would normally go into the actual
display buffer.  The allows for the extended attributes that some devices
and workstation controllers support.   Most notably, the ability to change
the display attribute without wasting a display byte.  Unfortunately, this
stuff is rarely used because it's not widely supported.

Actually, the 3487-ECB emulation means NON-ECB support.  Less memory
required and hence you get 4 sessions rather than 2.
