Another source is here: https://www.pcorner.com/list/GRAPHUTI/ZANSI12.ZIP/INFO/

(I don't currently have a program installed that can unpack the ARC
files provided by your source.)

The other common ANSI.SYS replacement was NNANSI.SYS, from Tom Almy,
available from http://almy.us/dospage.html

NNANSI was implemented as a TSR COM file instead of being a driver.
This is useful if you use things like DOSbox, which doesn't support
drivers loaded from CONFIG.SYS.

(I use DOSbox to run some old DOS apps on an Android tablet, with
NNANSI loaded as a TSR.)

I load NNANSI as a TSR high here, so the difference in size isn't a big factor.

Another plus for NNANSI is support for the VT-100 Add Line and Delete
Line sequences that are missing in ANSI and NANSI.

FreeDOS was intended to be DOS compatible and used in place of MSDOS,
so it can run on retro hardware.
