Sinclair ZX Spectrum 8x8 glyphs scripted by dpla:
""""""""'""'""""""""'"""'""""""                  


PART I. In order to NARROW this system (ROM) font
a basic filter was applied (without subsampling):
1. triple each character, that is: x-1, x and x+1
2. double these triplets, that is: left and right
3. delete 1 column/2= make 4x8 left & right chrs.
See my related Png and notice 2 px of h. padding.
                                                 
(\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\)
                                                 
Now that your narrowed 'sextuplets' are computed,
combine them all (w/o extra boolean operation)...

15 mixes are visible copies thus are not applied;
the order of overlaid layers does not count then.
                                                 
THERE ARE 21 MIXES IN ALL: 'A-U' as listed above;
you can preview them via the 21 UDG characters...
                                                 
Pseudo duplicates occur into brackets from x+/-1:
aligned (A)/P (B)/M <C>/R (D)/Q H/(O) I/<N> L/(U)
where '()' is objective and alas '<>' subjective,
and character #128 (copyright sign) variates btw.
                                                 
Total widths (in px) are factually the following:
3 in AU, 4 in BGLMPST, 5 in CDHINOQR & 6 in EFJK;
while the perceived ones look like the following:
3 in AGILNPSU, 4 in BHJMOQT, 5 in CEKR & 6 in DF,
because of "T", "Y", "_", #128 & the wide blocks;
a narrower lowercase is in BCFMRT except for "q".
                                                 
A COMPOSITE FONT may be done out of these styles,
by picking the glyphs from the exact code points,
into a final grid of 3x8, 4x8, 5x8 or 6x8 pixels.
+ Verify that no glyph repeats in a SAFE 0x20-7F.
