Yes. I wrote a version of Minesweeper for the Amstrad CPC, a home computer popular in 1987 (though I wrote it a few years later). I think it was about 5-10Kb in size, not 300. The CPC only had 64k of memory anyway, though a 128k model was available.

7yo me could not understand how people could possibly make software but I knew I wanted to be part of it. I loved my CPC 6128.

Even the Windows 95 Minesweeper was only a 24 kilobyte program.

As long as you did not count the large libraries it was calling into.

Probably a little later but I had an Amstrad 8086 as a teen. I think it was the first computer I bought with my own money.

16kb of the 64kb was reserved for the screen buffer if i remember correctly.
