Hell I’d probably just make “comics-list.txt” and just manually list them. Not individually probably, but like
Action Comics - #1 CGC 9.9
Batman (2nd) - 404-407
Beneath The Trees Where Nobody Sees - A (complete), B (complete), ashcan.
Creepshow (1st) - 1D, 2-5A
Creepshow (2nd) - 1-2A, 3C, 4-5A
Creepshow (3rd) - 1A
Earthworm Jim - #1
Or something to that effect.
Antix will run on old grey boxes with mb of ram, it oughta work for you too.
