I realized yesterday that it might be more useful if I left off all the One Page prices, weights, and rules assumptions from these cards, so that you can put on them whatever's appropriate in your rules system and campaign.
The weapon kits, of course, can't be system neutral entirely. For example, the "civilian" kit for wizards has a crossbow, the "rogue" kit for thieves has a bow and arrows, choices not supported by AD&D. I also included the mace in the "cleric" kit but some DMs may allow religion-specific weapons. You may want to substitute appropriate weapons (darts, sling) or just say that the weapon is for hirelings or other party members to use.
Hope these are useful!
