This is a standard JEDEC (.JED) format, which is the compilation of the file that tlinder placed above. (The file above uses an 20+ year old obsolete program, WinCUPL, and .JED is the preferred format to distribute GAL object files.)
You should be able to put the below contents in a file, rename it to "coco-3-U8.JED" or similar and then use your favorite device programmer to program a GAL16V8 with the file contents. Finally, replace the PAL14L4 in your 26-3024 with the GAL16V8 to get it to work with your Color Computer 3.

Also, for fun, here are the actual equations derived from the above Coco3 MPI JED file, as reported by MAME's jedutil:
Inputs:
1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 17, 18, 19
Outputs:
14 (Combinatorial, Output feedback output, Active low)
15 (Combinatorial, No output feedback, Active low)
16 (Combinatorial, No output feedback, Active low)
Equations:
/o14 = /i1 & /i2 & i3 +
/i19 +
/i18
o14.oe = vcc
/o15 = /i1 & /i2 & i3 & i4 & i5 & i6 & i7 & i8 & i9 & i11 & i12
o15.oe = vcc
/o16 = /i1 & /i2 & i3 & i4 & i5 & i6 & i7 & i8 & i9 & /i11 & i12 & /i13
o16.oe = vcc
And, finally, here are the original equations from the PAL14L4 that originally came with the 26-3024 (and works with the Coco 1 and 2). Notice that there's an additional line in the /o14 stanza here that isn't in the "fixed" Coco3 version, above, "/i1 & i2 & /i3 & /i4 +".
Inputs:
1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 18, 19
Outputs:
14 (Combinatorial, No output feedback, Active low)
15 (Combinatorial, No output feedback, Active low)
16 (Combinatorial, No output feedback, Active low)
17 (Combinatorial, No output feedback, Active low)
Equations:
/o14 = /i1 & /i2 & i3 +
/i1 & i2 & /i3 & /i4 +
/i19 +
/i18
o14.oe = vcc
/o15 = /i1 & /i2 & i3 & i4 & i5 & i6 & i7 & i8 & i9 & i11 & i12
o15.oe = vcc
/o16 = /i1 & /i2 & i3 & i4 & i5 & i6 & i7 & i8 & i9 & /i11 & i12 & /i13
o16.oe = vcc
/o17 =
o17.oe = vcc
