VDU programming question



All --

My latest project is to get the video portion of the VDU working with the SBC188 board. The automated Z80->x86 translation is ugly so I've been rewriting the code from scratch. I've been able to get the screen cleared and the cursor "home" but I haven't been successful in getting any text to print. In my latest attempt I've gotten a bunch of jumbled bits to print, but that’s it.

Does anyone have any words of wisdom or magical incantations to getting this working? I've been using the Z80 code in "vducons.asm" as a programming guide. My x86 skills are ok but not great.

Thanks!
