The now open source tool "pcb elegance" gerber load code appears to cope
with gerber aperture files. You may be able to load up the old gerbers and
aperture files and then attempt export of rs-274x gerbers from pcb elegance.

Once you have rs-274x gerbers, they xan be turned intoa footprint with
translate2geda
or translate2coralEDA for loading into gEDA pcb or into pcb-rnd.

I managed to get pcb elegance running under wine on lubuntu. Their gerber
viewing tool seems to cope better with loading polygonal flashed apertures
than the pcb tool, but this should not be an issue for a 1990s rs-274d
board iiuc.

Failing that, i could try to add the ability to load an aperture file in
conjunction with a gerber file in my utilities translate2geda and
translate2coralEDA (available on github).

translate2coralEDA exports proper padstacks for pcb-rnd with polygonal pad
definitions, allowing round rect, obround, square, rect, circular, etc
pads, which may not be an issue for a 1990s board, but, you may be able to
take advantage of the padstack prototypes in pcb-rnd to add drills to all
padstacks of the same geometry, for example, in one fell swoop, since a
gerber layer will not include drill information.

Good luck!

Erich
