The 5x6 grid is not very roomy for good fonts. After a bit of experimenting I ended up with the rectangular fonts that follow. I thing they are readable from longer distance.

@ dw 0x89F,	0x891,	0xF91      ; 0
@ dw 0x206,	0x204,	0xF84      ; 1
@ dw 0x81F,	0x9F,	0xF81      ; 2
@ dw 0x81F,	0x81E,	0xF90      ; 3
@ dw 0x489,	0xF89,	0x408      ; 4
@ dw 0x9F,	0x81F,	0xF90      ; 5
@ dw 0x9F,	0x89F,	0xF91      ; 6
@ dw 0x81F,	0x410,	0x408      ; 7
@ dw 0x89F,	0x89F,	0xF91      ; 8
@ dw 0x89F,	0x81F,	0xF90      ; 9
@ dw 0x200,     0x0,	0x200      ; :
@ dw 0,0,0                         ; space
