Common Platforms

[MbeeTech]

In terms of hardware support, I'd prefer to support platforms of Microbee that are in common use now.

From what I can see there are three variants (that will effect the software):

Original black and white
Original colour format
Premium colour format
Wide screen (256TC)

Actually the last 2 are really the same. The 256TC has no difference in capability from the Premium series, with the exception of hardware character flashing.
The screen formats achievable are equal on both. I assume you are referring to the 256TC boot screen menu when mentioning widescreen.

Just as a guide, if you look through the forum, the microbee is also capable of the 32x24 colour screen as used by the ZX Spectrum, the 256 x 224 format of the Space Invaders Arcade machine, MSX text and graphics modes & Amstrad CPC text/graphics modes including 160x200, 320x200.

While this is true, just for clarity, most (if not all) of these modes mentioned require either standard or non-standard modifications that are not on some models.
For example, the 'Videotex' mod / upgrade was available for standard (non-premium) machines to halve the pixel clock rate to provide 40 columns instead of 80 columns.
The Premium series and 256TC have this mod built in, but the standard machines needed a small board fitted to achieve this.
