Brilliant.
A number of comments:
* He mentions there is no multi tasking in dosshell. I'm not 100% sure about MS-DOS 5.0, but in ver 6.0 you could switch between tasks in dosshell [EDIT: this is also true for version 5.0, you can see the option at 1:13 in his video]. To switch tasks you need to first enable it through the "Options" menu ("Enable Task Swapper") and then you can either switch tasks by the all too familiar Alt+Tab or pressing Ctrl+Esc to bring up an ancient Task Manager (then titled "Active Task List").
* I may be mistaken, but in later service packs Win2000 had much better DOS emulation... Just mentioning it because he did test XP SP2 and later versions of Win2000 may have handled Doom2 better.
This video got me to dig out my old DOS book to make sure I remember correctly... ah, the memories :) Very interesting to see many dialogs we all know from Windows even in DOS (i.e. the Run and Associate File extension dialogs in dosshell)
- georgieporgie 16y agoin ver 6.0 you could switch between tasks in dosshell That was task swapping, not multitasking. All but the currently-executing task were interrupted, written out to disk, and expunged from memory.
- bad_user 16y agoNot completely true. In MS-DOS you could terminate a program, but make 64K of its memory resident. And then you could program a time interrupt handler to wake it up and do stuff periodically. That's how some viruses worked btw :-)
- gaius 16y agoTSR, that was called, terminate and stay resident. It was a legitimate technique, software like Sidekick used it http://en.wikipedia.org/wiki/Borland_Sidekick http://en.wikipedia.org/wiki/Borland_Sidekick
