After more than half a century, UNIX v4 tape has been found in the University of Utah, and is now live in the Internet Archive!

Someone dropped a massive (500GB) blob of 1990s IBM warez on Archive.org. It included some #InteractiveUnix releases I hadn't previously seen. Also versions of dBase, Lotus 123, Wordperfect ... and Microsoft Word 5 for UNIX!

Plus #FPGA and #PLD development software for AT&T's ORCA - and Neocad's FPGA Foundry, which is the base Xilinx ISE was built on.

Does anyone have Sun patches 107235-01 (at Y2K fix) and 107436-01 (fsck fix for large FSes) for Interactive Unix 4.1.1?

They're from around April 1999 and may be on a Sun Patches CD from around that time.

Sadly they're not on Archive.org, or the ZX[1] and ICM[2] mirrors of Sun's ~2006 FTP.

Boosts and shares appreciated!

Interesting progress on that #Plexus P/20 machine in Adrian's latest video. The first ten minutes are just about the reset circuit and pretty mundane, but then it picks up.

Any #oldunix gurus around?

ISC Interactive Unix 4.1. Installer (from http://tenox.pdp-11.ru/os/interactiveunix/ ) runs but locks up after partitioning the HDD.
This is on a 430HX, motherboard IDE and a 2GB CompactFlash card, with K6-2 400 CPU and 96MB RAM.
Tried limiting the cylinder count in the BIOS and installer, no change.

Also looking for 3Com 3C509B drivers for the same OS, if anyone has them.
