Old School FRP is one of my favorite Tumblr accounts --- I've had them in the sidebar here for years; see the section called "Crystal Ball" --- and they consistently post great old school art from TSR and other FRPG products. Yesterday they posted a review of The Ruined Tower of Zenopus:
"I bought this and gave it a first read-through. It is an excellent conversion of one of my favorite classic low level adventures, updated for 5e. There are some new monster stat blocks and minor magic items, a little town map on a peninsula (which makes it easier to locate the town on almost any coastline), options for expanding some areas, notes on factions, rumors, and ways to tie Portown to Saltmarsh, plus even 4 pre-gen PCs. Check it out."
The Ruined Tower is available on DMs Guild
