DOS ain't dead

Disassembly of setclock.com from MS-DOS v1.25 code release (Announce)

posted by tkchia , 14.04.2020, 16:55

In case it is useful: I recently did a disassembly of the setclock.com program included in Microsoft's code release of MS-DOS v1.25:

https://gitlab.com/tkchia/MS-DOS-disassembly/-/blob/master/v1.25/disassembly/setclock.asm

This is apparently a TSR program which reads and sets a particular type of hardware real time clock.

Thank you!
