I completed Classic Modules Today: X1 The Isle of Dread 5e and it is now live. What a monster. There is a decent sized list of Notable NPC's and New Monsters which make up the meat of this conversion guide. Not too many Magic Items and Spells needed conversions and the traps were relatively straightforward.
I did add notes on my thoughts on why I've changed the modules level recommendations from 1e, change in Challenge Ratings and XP awards, as well as why a 5e Dungeon Master should consider dialing down the cash value of treasure.
Like all the rest of the conversion guides being produced by fans working this project I sincerely believe use of the guide will relieve hours of prep work and let the DM focus on using these classics for tons o' fun at the table!
