Feasible? Yes. Slow? ABSOLUTELY!
This is the reason I created AsciiPixels. It provides two main features
critical to the M100:
1. It is machine language graphics routines, so it is blazingly
fast relative to BASIC.
2. It provides a level of image compression similar to Linux 'xz'
compression in most cases:
Full screen image (i.e. image size is 240 x 64 pixels):
dragon.do 825 bytes This is the APRAW encoding
dragon.ap 640 bytes AsciiPixels encoding
dragon.pbm.xz 628 bytes Linux xz compression
dragon.bmp 2178 bytes
dragon.pbm 1969 bytes Original non-compressed 1-BPP bitmap:
240x64 pixels / 8 pixels/byte =
1920 + header

It might be feasible to decode a BMP in plain basic on a T100/T200 imho.

It might be difficult to code, but would a conversion to BMP not
be possible? Considering the never-changing nature of the Model
T's screen (240x64, monochrome) it shouldn't take too much place.
Even if .BMP is a wastefull standard, it would give an easy way to
interchange screendumps and logos to and from the Model T.
