AutoCAD 2.15 (5-7-85) IBM PC
Released in 1985 by Autodesk
For DOS

To install, copy the contents of each floppy in to a folder on your
hard drive.

Run ACAD.EXE, and select option 5 from the menu to configure your
hardware.

The maximum supported resolution under standard systems is 640*350*16
using "IBM Enhanced Graphics Adapter" with "Enhanced Color Display".

If a Microsoft mouse compatible DOS driver is present, you can use
"Microsoft Mouse" as your digitizer device.

Important!!!!!!!: Version 2.15 is extremely buggy. If you are looking
to just kick around an old version of AutoCAD, you probably don't
want 2.15. It will fail to start, with a "Divide Overflow" error on
anything much faster than a 286. It also has additional problems
running under DOSBox. Tested to work with MESS using the PC/AT
driver.

These bugs are fixed in later versions such as 2.18.
