Sorry, I misspoke... You need to do some hacking to your ST motherboard
as well, to use overscan. If you'd rather not do that, you're better off
just tweaking the monitor. (It looks like a simple enough mod, though;
cut one trace, add a couple wires and a [debounced!] toggle switch.)

The software is available on terminator.cc.umich.edu. I don't have PageStream,
dunno what it knows. I know that Uniterm doesn't like it very much. I wrote
to Simon Poole, asking if he'd put out a new release that supports non-standard
screen sizes. Got no reply, so I've disassembled it and fixed it myself.
It's pretty cool now, 60 lines by 137 columns of text.

How do you start up Spectre GCR? The Overscan program runs from the AUTO
folder and tweaks some Line-A and other system variables. If you can boot
TOS before you start up Spectre, you might have a chance. Otherwise I doubt
it, but don't really know. If you wanted to make sure, you might be very
enterprising and burn your own TOS ROMs with the Overscan mods applied...
