[comp.sys.m6809] DynaStar -vs- Disto 80-Column Card

[I may have posted something like this before; did it get out?]

I've been trying to upgrade my wife's Coco 2 to use the
DISTO 80-column card that fits inside the disk controller.
It's very nice, but has trouble with the DynaStar screen editor
(Frank Hogg Labs).  Under OS9 1.0 (original), it sometimes
works fine but usually goes ape-wild for half a minute whenever
the screen scrolls up or down (the "light show").
Under 1.2 ("Version 2") the whole system locks up and disk motors
stay on as soon as Dyna tries to write the screen.

On Delphi (the "other CompuServe"), the experts disagree on
lots of things about my problem:  is this problem hardware or software,
is Disto's co80.io driver even supposed to support Dynastar's
extended control code set, and is Version 2 OS9 more or less
likely to work.
Funny, Tony DiStefano who designed the hardware says it's a
hardware problem, send it back for repair.
Ken Scales, who long ago dis-assed and rewrote co80.io
to handle Dynastar (but only for V2) swears the problem is
NOT hardware despite its intermittent nature.
His patched driver hangs our machine just as before.

I'm using Dave Lewis' NEWDISK driver in Version 2, and SDISK
in Version 0.  I'm not using a MultiPak (no room on her desk,
that's why Disto instead of the tried and true WordPak).

My wife says she's gonna run out and buy a PClone,
and with the Delphi connect charges and paying myself minimum wage
I've probably paid for one by now.
I'd appreciate any ideas FAST.  Thanks.
