The name was VT50PY, or DISPLY, or something like that.

In V10.1, that program would do ANSI escape sequences if the terminal
appeared to be a VT100 or above (i.e., a scope with XON support and no
fill). But, judging by the sources, that wasn't available before
V10.1. So you can change the code :-) or you can track down an xterm
with VT52 escape support, or you could add it to xterm (VT52 escapes
are pretty simple...)

------------- Ashley's stuff below (pardon me for leaving the
large amount of the previous message up above. I know someone
will scold me for that)

I have VT50PY (yes that's the name) running on my PDP-11. And yes,
that's the program that used to bring the system to its knees on
weaker systems.

I am out of town right now, but in order to make the thing work, you
have to load the BASIC+ source for (I think) DISPLY.BAS and then
APPEND VT50.DPY (or something like that - I'm saying this from
memory and my memory is faulty). Then COMPILE it, and run it. If
you want to allow non-privileged users to run it, compile it to <232>.

It uses the VT50/VT52 escape sequences to clear and update the
screen, so you need to do VT50/VT52 emulation. It does have a
switch to allow you to use 24 line VT52 mode vs the standard 12
line VT50 mode.

I'll check on the details when I get back home. Sounds like you need
to make sure your terminal emulator is doing VT50 or VT52 emulation.
It runs fine on my real VT52s or on my telnet sessions with VT52
emulation.
