Got bored this evening. I remembered a past topic by tepo about a 386, very small HD and 8 Mb RAM. Dug out the thread to find the QNX demo disk link.

Hoping to have some fun too, I downloaded the demo and created the disk, but my 486SX with 8 Mb RAM isn't enough. QNX needs 8000 Kb of memory and only detects 7808 Kb on this machine, even with all shadowing disabled.

Is there an older version somewhere ?
