[Coco] Printing from Disk Extended Color Basic (via Drivewire)

[Ron Klein]

Hi John,

I see I have some catching up to do on the mailing list replies for my
question about printing from DECB via Drivewire.  Believe me, I do listen
to and enjoy the Coco podcasts!  In fact, I found the one on printing with
the TP-10 so interesting, I decided to get one of my very own and was able
to acquire one from one of members of the Coco Facebook page (thanks, Joe
Joe)!

Brett did reply in a recent email as to why I was looking for this
capability.  He suggested a TSR to patch BASIC in RAM which is, more or
less, what you talked about in the tech segment in your podcast.

Looks like I have a bit of fun work to do.

Thanks!
