Yeah, those and about a zillion other terminals will emulate a 4014.
They're almost all bitmapped, so most of them allow selective erase.
Since selective erase wasn't something that the original Tek storage
tube terminals did, the 4010/4014 command set didn't include a 'selective
erase' (or 'draw black vector') command.  The original Tek command set
became a de facto standard for low-budget graphics of that type, but
the standard fell apart when it came to selective erase or anything else
that wasn't in the original "standard"... You need to find a manual
for whatever emulator you're using, and augment your Plot10 or TCS or 
whatever driver to send the appropriate code for the emulator you have.
