All --

While digging through my boxes this weekend, I found a CompuPro Spectrum video graphics card. Unsure if it works or not. The manual has some good detail, but no programming examples (other than a memory test program). Can anyone point me to further information and/or code examples for this board? Googling doesn't produce much that's useful. The manual also mentions a subLOGIC graphics interpreter package for it (assuming Z80 target).

Any info appreciated! Thanks!
