8088 Domination Demo running on IBM PS/2 Model 30 286

My entry to the r/retrobattlestations contest. I decided to use this freshly restored IBM PS/2 Model 30 286 I got a month ago from a warehouse. It has 10MHz 286 CPU, 1mb of RAM and 30mb original IBM hard drive.
This machine was used in a school in St. Petersburg from 1992 till 1999. Machine itself was in a rather good shape and working condition, except for dead floppy with leaky capacitors, dead Dallas clock chip and problems with monitor switch. The keyboard, an original Model M, had one key missing and was really dirty. I repaired everything, cleaned and reassembled. I also managed to get the missing key (can you guess which one it was?) and an original IBM PS/2 mouse. All original software on the harddrive is still intact, and 1gb CF card was added via XT-IDE.
