If I understand this correctly the MS DOS 4 here is not the same as the copy I have on 720k floppies in my basement. Since I have the shipping versions of 3.3 - 6.22 I'm guessing your referring to a product that never saw the light of day. Or I have the one your talking about and just didn't know it.

It would be interesting to compare this MS DOS 4.0 with DR Concurrent DOS, and the DR DOS 6.0 and 7.0.

Eg, how differently did the two OS vendors implement multitasking, with all that that implies in terms of protection of tasks in an insecure (real mode) environment?

See http://blogs.msdn.com/larryosterman/archive/2004/03/22/94209.aspx for more details on this one.

And Wesley, I have no idea. IIRC, DR DOS 6.x required a 386 and did their multitasking using VxD's. I'd be surprised if they worked on IBM PC XT's.

Exchange History and those darn NMNs

I heard that Exchange was purchased by Microsoft, but it seems clear that you were working on new development. Maybe it was just the MTA that was purchased? I also heard that Exchange was initally written in Pascal and was ported to C using a translator, and that's why it took so long to come out with the 5.0 version. Why was Exchange started with version 4.0? And who DID write that NAT unfriendly push notification (New Message Notification)? Why didn't they just utilize one of the two open TCP connections from the client to the Exchange server to send a push notification?

Thanks!

i ran drdos 6 on a 286 20. The multitasking was a toy for me, but I think it worked.

So why on Earth did you do that stupid 'push notification' thingy in Exchange, and why is it so NAT unfriendly?
