Can you share the schematic? I'm not familiar with KiCad or other similar software, so take this with a grain of salt, anyway I think that for simple schematics, especially that old, meaning all tht parts, single side pcbs, unless one is recreating a complex circuit, probably the "by hand" approach is a lot faster than using software.
