How the Atari ST almost had Real Unix

The latest problem I was working out was how to run Unix on the Atari ST. The Tramiels had somehow wrangled a license for AT&T’s SVR-something-or-other version of Unix (might have been SVR3, but this was in the bad old days when AT&T was actively fucking up Unix, and it could have been just about any version, including SVR666). The license was for a mind boggling, nay, jaw-dropping ten bucks a seat. The problem was that the ST didnโ€™t have any kind of memory management hardware, just a raw CPU flinging real addresses at naked DRAM, and the machine’s cheap-ass vanilla 68000 was incapable of recovering from a fault unless you cheated.

On a related note, there’s MiNT.
