The old font sizes were: 72, 37, 27.
I started over to create the sizes 1024, 512, 256, 128, 65, 33, 16.

How I did it:

   Photoshop:

     Font "Times", Bold, PS Type1, Adobe 1985-1997, Linotype
     1459.47 point font, text "1 2 3 4 5 6 7 8 9 0 - :"
     Save as GIF dalifontA.gif

     Scale by 6.25% (1024 => 64)
     Save as GIF dalifontE.gif

     Scale by 50% (64 => 32)
     Save as GIF dalifontF.gif

     Scale by 50% (32 => 16)
     Save as GIF dalifontG.gif

   Convert to individual 1024-tall XBM files:

     giftopnm dalifontA.gif | pgmtopbm -threshold | \
       pnmcrop -top -bottom > all.pbm

     pamdice -outstem=out -width=1080 all.pbm

     for f in out*.pbm ; do pnmcrop -left -right $f > a && mv a $f ; done

     pnmcat -tb out*.pbm | pnmpad -white -left=16 -right=16 \
       > all2.pbm ; rm out*.pbm

     head -2 all2.pbm # (char height is 12288 / 12 = 1024)

     pamdice -outstem=out -height=1024 all2.pbm

     mv out_00_00.pbm oneA.pbm
     mv out_01_00.pbm twoA.pbm
     mv out_02_00.pbm threeA.pbm
     mv out_03_00.pbm fourA.pbm
     mv out_04_00.pbm fiveA.pbm
     mv out_05_00.pbm sixA.pbm
     mv out_06_00.pbm sevenA.pbm
     mv out_07_00.pbm eightA.pbm
     mv out_08_00.pbm nineA.pbm
     mv out_09_00.pbm zeroA.pbm
     mv out_10_00.pbm slashA.pbm
     mv out_11_00.pbm colonA.pbm

     # Make colon and slash be the same size, but smaller than the digits:
     pnmcat -tb slashA.pbm colonA.pbm | pnmcrop -left -right | \
       pnmpad -white -left=16 -right=16 > all2.pbm
     pamdice -outstem=out -height=1024 all2.pbm
     mv out_00_00.pbm slashA.pbm
     mv out_01_00.pbm colonA.pbm

     rm all.pbm all2.pbm
     for f in *.pbm ; do pbmtoxbm $f > `echo $f | sed 's/pbm/xbm/'` ; done
     rm *.pbm

   Scale the "A = 1024" images down to make most of the smaller versions:

     # B = 512
     for f in *A.xbm ; do \
       xbmtopbm $f | pamscale -reduce 2 | pgmtopbm -threshold \
         > `echo $f | sed 's/A.xbm/B.pbm/'` ; \
       pbmtoxbm `echo $f | sed 's/A.xbm/B.pbm/'` \
         > `echo $f | sed 's/A/B/'` ; \
     done
     rm *.pbm

     # C = 256
     for f in *A.xbm ; do \
       xbmtopbm $f | pamscale -reduce 4 | pgmtopbm -threshold \
         > `echo $f | sed 's/A.xbm/C.pbm/'` ; \
       pbmtoxbm `echo $f | sed 's/A.xbm/C.pbm/'` \
         > `echo $f | sed 's/A/C/'` ; \
     done
     rm *.pbm

     # D = 128
     for f in *A.xbm ; do \
       xbmtopbm $f | pamscale -reduce 8 | pgmtopbm -threshold \
         > `echo $f | sed 's/A.xbm/D.pbm/'` ; \
       pbmtoxbm `echo $f | sed 's/A.xbm/D.pbm/'` \
         > `echo $f | sed 's/A/D/'` ; \
     done
     rm *.pbm

   Start over with the "E" image, for better smoothing:

     giftopnm dalifontE.gif | pgmtopbm -threshold | \
       pnmcrop -top -bottom > all.pbm

     pamdice -outstem=out -width=67 all.pbm

     for f in out*.pbm ; do pnmcrop -left -right $f > a && mv a $f ; done

     pnmcat -tb out*.pbm | pnmpad -white -left=1 -right=1 \
       > all2.pbm ; rm out*.pbm

     head -2 all2.pbm # (char height is 780 / 12 = 65)

     pamdice -outstem=out -height=65 all2.pbm

     mv out_00_00.pbm oneE.pbm
     mv out_01_00.pbm twoE.pbm
     mv out_02_00.pbm threeE.pbm
     mv out_03_00.pbm fourE.pbm
     mv out_04_00.pbm fiveE.pbm
     mv out_05_00.pbm sixE.pbm
     mv out_06_00.pbm sevenE.pbm
     mv out_07_00.pbm eightE.pbm
     mv out_08_00.pbm nineE.pbm
     mv out_09_00.pbm zeroE.pbm
     mv out_10_00.pbm slashE.pbm
     mv out_11_00.pbm colonE.pbm

     # Make colon and slash be the same size, but smaller than the digits:
     pnmcat -tb slashE.pbm colonE.pbm | pnmcrop -left -right | \
       pnmpad -white -left=1 -right=1 > all2.pbm
     pamdice -outstem=out -height=65 all2.pbm
     mv out_00_00.pbm slashE.pbm
     mv out_01_00.pbm colonE.pbm

     rm all.pbm all2.pbm
     for f in *.pbm ; do pbmtoxbm $f > `echo $f | sed 's/pbm/xbm/'` ; done
     rm *.pbm

   Likewise, start over with the "F" image.

     giftopnm dalifontF.gif | pgmtopbm -threshold | \
       pnmcrop -top -bottom > all.pbm

     pamdice -outstem=out -width=34 all.pbm

     for f in out*.pbm ; do pnmcrop -left -right $f > a && mv a $f ; done

     pnmcat -tb out*.pbm | pnmpad -white -left=1 -right=1 \
       > all2.pbm ; rm out*.pbm

     head -2 all2.pbm # (char height is 396 / 12 = 33)

     pamdice -outstem=out -height=33 all2.pbm

     mv out_00_00.pbm oneF.pbm
     mv out_01_00.pbm twoF.pbm
     mv out_02_00.pbm threeF.pbm
     mv out_03_00.pbm fourF.pbm
     mv out_04_00.pbm fiveF.pbm
     mv out_05_00.pbm sixF.pbm
     mv out_06_00.pbm sevenF.pbm
     mv out_07_00.pbm eightF.pbm
     mv out_08_00.pbm nineF.pbm
     mv out_09_00.pbm zeroF.pbm
     mv out_10_00.pbm slashF.pbm
     mv out_11_00.pbm colonF.pbm

     # Make colon and slash be the same size, but smaller than the digits:
     pnmcat -tb slashF.pbm colonF.pbm | pnmcrop -left -right | \
       pnmpad -white -left=1 -right=1 > all2.pbm
     pamdice -outstem=out -height=33 all2.pbm
     mv out_00_00.pbm slashF.pbm
     mv out_01_00.pbm colonF.pbm

     rm all.pbm all2.pbm
     for f in *.pbm ; do pbmtoxbm $f > `echo $f | sed 's/pbm/xbm/'` ; done
     rm *.pbm

   Likewise, start over with the "G" image.

     giftopnm dalifontG.gif | pgmtopbm -threshold | \
       pnmcrop -top -bottom > all.pbm

     pamdice -outstem=out -width=17 all.pbm

     for f in out*.pbm ; do pnmcrop -left -right $f > a && mv a $f ; done

     pnmcat -tb out*.pbm | pnmpad -white -left=1 -right=1 \
       > all2.pbm ; rm out*.pbm

     head -2 all2.pbm # (char height is 192 / 12 = 16)

     pamdice -outstem=out -height=16 all2.pbm

     mv out_00_00.pbm oneG.pbm
     mv out_01_00.pbm twoG.pbm
     mv out_02_00.pbm threeG.pbm
     mv out_03_00.pbm fourG.pbm
     mv out_04_00.pbm fiveG.pbm
     mv out_05_00.pbm sixG.pbm
     mv out_06_00.pbm sevenG.pbm
     mv out_07_00.pbm eightG.pbm
     mv out_08_00.pbm nineG.pbm
     mv out_09_00.pbm zeroG.pbm
     mv out_10_00.pbm slashG.pbm
     mv out_11_00.pbm colonG.pbm

     # Make colon and slash be the same size, but smaller than the digits:
     pnmcat -tb slashG.pbm colonG.pbm | pnmcrop -left -right | \
       pnmpad -white -left=1 -right=1 > all2.pbm
     pamdice -outstem=out -height=16 all2.pbm
     mv out_00_00.pbm slashG.pbm
     mv out_01_00.pbm colonG.pbm

     rm all.pbm all2.pbm
     for f in *.pbm ; do pbmtoxbm $f > `echo $f | sed 's/pbm/xbm/'` ; done
     rm *.pbm

  Then fix the declarations in the xbm files:

     for f in *.xbm ; do \
       sed 's/ char / unsigned char /' < $f > a && mv a $f ; \
     done

#############

  Unfortunately, those sizes aren't optimal for PalmOS screens, which are
  generally only 160 pixels wide.  The "D" characters are 88 wide (not 80).
  So let's make a D2 image that is just slightly smaller than the D image:

     giftopnm dalifontA.gif | pamscale 0.1136 | pgmtopbm -threshold | \
       pnmcrop -top -bottom > all.pbm

     pamdice -outstem=out -width=123 all.pbm

     for f in out*.pbm ; do pnmcrop -left -right $f > a && mv a $f ; done

     pnmcat -tb out*.pbm | pnmpad -white -left=1 -right=1 \
       > all2.pbm ; rm out*.pbm

     head -2 all2.pbm # (char height is 1392 / 12 = 116)

     pamdice -outstem=out -height=116 all2.pbm

     mv out_00_00.pbm oneD2.pbm
     mv out_01_00.pbm twoD2.pbm
     mv out_02_00.pbm threeD2.pbm
     mv out_03_00.pbm fourD2.pbm
     mv out_04_00.pbm fiveD2.pbm
     mv out_05_00.pbm sixD2.pbm
     mv out_06_00.pbm sevenD2.pbm
     mv out_07_00.pbm eightD2.pbm
     mv out_08_00.pbm nineD2.pbm
     mv out_09_00.pbm zeroD2.pbm
     mv out_10_00.pbm slashD2.pbm
     mv out_11_00.pbm colonD2.pbm

     # Make colon and slash be the same size, but smaller than the digits:
     pnmcat -tb slashD2.pbm colonD2.pbm | pnmcrop -left -right | \
       pnmpad -white -left=1 -right=1 > all2.pbm
     pamdice -outstem=out -height=116 all2.pbm
     mv out_00_00.pbm slashD2.pbm
     mv out_01_00.pbm colonD2.pbm

     rm all.pbm all2.pbm
     for f in *.pbm ; do pbmtoxbm $f > `echo $f | sed 's/pbm/xbm/'` ; done
     rm *.pbm

     for f in *D2.xbm ; do \
       sed 's/ char / unsigned char /' < $f > a && mv a $f ; \
     done
