- GDC diagnostic disk bails out on 9 of 13 tests (tests 4 and 6 - 13). Scroll check doesn't...

|

Interaction of Upd7220 and Rainbow.cpp:

- FIG directions / params appear to be odd (lines go 45 degrees up or down instead of straight dir.),
|

- RDAT with MOD 2 is unimplemented. WDAT appears to set "m_bitmap_mod" wrongly ("2" means all pixels will be reset)...
|
||||
Freeware to try: MMIND (MasterMind, after BMP logo), SOLIT (Solitaire), CANON (high resolution + vectors).

Driver is based entirely on the DEC-100 'B' variant (DEC-190 and DEC-100 A models are treated as clones).
|

While this is OK for the compatible -190, it doesn't do justice to ancient '100 A' hardware.
|
||||
The public domain file RBCONVERT.ZIP documents how model 'A' differs from version B.
