TBOS has an 8086/88 branch for XT's and higher! All you need is your old box and a 1.44 MB floppy drive!Basically this is just TBOS using 8086/88 instructions. Everything else is the same, just this branch isn't updated as often as well as having a few differences: This branch doesn't support 80x30, 80x50, and 40x50 text modes. This branch uses macros to implement jxx near, pusha, and popa. Numerous smaller differences.
