Armchair Gamer for sharing this.
There is a group online that are converting classic D&D adventures over to 5e and putting them up for sale on the DM's Guild.
Classic Modules Today has a website, a Google+ group and of course modules for sale at DM's Guild. They are working through a list of modules and you can see their progress on their website.
I grabbed their updates for the Drow series, D1-2 Descent into the Depths of the Earth and D3 Vault of the Drow for a buck each.
Sure there is nothing there I could not figure out on my own, but it's all here and only a buck.
I also grabbed their conversion of B4 The Lost City. It has conversion file (which I don't really need) but also the OpenOffice document files you can use to create your own conversions.
Maybe one day I will do the conversions of the D&D4 Orcus vs. the Raven Queen adventures. They are not exactly classics, but I would still like to run them some day.
