While we're on the subject of artificial differences, does
anyone remember the price schedule on the DEC DL11 series?
There were actually two different boards, the M7800 and the
M7800-YA.  The -YA model didn't have the chips for EIA; it
was strictly 20 mA loop and was used in the DL11-A and DL11-C
versions.  The DL11-B, -D, and -E were all the M7800 board
and had EIA drivers as well as current loop.  That's really
not my point, though.

The DL11-E was a more expensive board than the others because
it had modem control -- DTR, RTS, CTS, DCD, etc. were brought
out to registers.  It was only a jumper change (well documented
in the engineering drawings) to convert a -B or -D board to
an -E though.
