I just spent a few hours installing Windows NT 3.51 and fiddling with PCI network cards. Why? To prove a point on the Internet, of course. System specs: Asus Maximus Extreme (X38) Intel Core 2 Quad Q9550 Asus GTX 750 Ti OC (using VBEMP driver and Q174567 hotfix) 8 GIB (4× 2 GiB) DDR3-1333 (NT 3.51 sees 3.5 GiB) 640 GB SATA HDD Realtek RTL8139D PCI (network card with NT 3.51 drivers – take that!) Windows NT 3.51 Workstation RTM
Windows NT 3.51 can connect to the Scratch website using RZBrowser, available here: o.rthost.win/gpc/files1.rt/rzbrowser-tls12-20180504.7z Update 2026-05-01: This link no longer works, since Cloudflare thinks anyone visiting the site is a bot. RZBrowser can still be downloaded using the Wayback Machine: web.archive.org/web/2025/o.rthost.win/gpc/files1.rt/rzbrowser-tls12-20180504.7z
