Ah, thank you! E-mailed. That would indeed help.

It may interest any A-112 owners to know that someone else has already made some software for it this year. You can read all about it over at http://www.muffwiggler.com/forum/viewtopic.php t=50154&start=all&postdays=0&postorder=asc

It's currently Windows only, but it's still being maintained, it's free and it works, so that's a good sign! I'll see if I can intercept the signal from that (no DOS required, yay), but even if not, there's some software available for people right now.

All the best,
Zoë.
