You didn't say if you are working under CP/M or LDOS. What are
you trying to do? Do you want to add the 25th line for CP/M?
Are you trying to get a 25 line driver for LDOS, instead of
the 16 lines it comes with? Are you trying to emulate a
terminal?
  Under CP/M there are 24 lines, the hardware programing would
have to be changed to get a 25th line. Under LDOS, the hardware
programing has to be changed to get more than 18 lines. In
either case, there is a lot of hacking to do. If you want a
good terminal program under LDOS, Logical Systems has a new
program out which emulates an ADDS terminal and supports the
"MODEM" protocal, and other goodies. It looks like a very good
piece of software, but it cost a couple hundrerd bucks. Also
note that you will need a good monitor to display a 25th line.
The Amdek monitors work fine, but I tried a 25 line display
on a Gorrila and got a lot of flicker. In any case, it is
possible, since I have done it. But it is a lot of work.
Good luck.
