I suppose non-support of earlier machines is a limitation on Z-Link's part,
but I've coded it using 65c02 opcodes and wrote certain things which are
inherent of 128k enhanced //es or more recent machines (80 cols, mousetext,
etc).

As for vt100, my original statement is not properly stated. I should have
said: I personally don't like vtxxx (ANSI) type terminals because of the amount
of overhead in doing the emulation. ANSI terminals use <ESC>[(row in decimal);
(column in decimal)H to address the cursor while vt52/h19 use <ESC>(row+32 in
binary)(col+32 in binary)Y. h19 always needs just 4 characters to address,
ANSI needs a varying amount from 3 to 8 characters (avg 5 or 6). See my point?
