Hello and welcome as a registered user :-)
(Our new user activation system requires users to introduce themselves in the "User-Anmeldungen" sub forum before we activate their accounts. This is meant to filter out spam, off topic postings and people who don't have a lasting interest in our forum anyway. The latter group are welcome to use the German or English guest forums.
If you don't speak any German, you couldn't, of course, be aware of that rule. Since you've posted here before, I've activated your account, which is now fully usable... We should probably mention our new activation system in the English Board, since users who don't speak English are welcome to create a user account as well. Your trying to sign up just made me aware of this issue :-) )
That software you mention sounds intesting. It's probably not that useful anymore, since most DOS users should have some form of Soundblaster card by now, but sure is an interesting thing to try... I wonder if it really runs smoothly or if it makes the PC run choppily every time a sample is played. As far as I'm informed, it's not a trivial thing to get the PC speaker to play samples while doing other stuff.
Pinball Dreams does it, though...
I guess I'll try it tomorrow. In Germany, it's 1:40 now and time for bed :-)
As for a Covox: I guess I'll have to build such a thing some day. I'm not a great expert (neither in understanding complex electronics nor in soldering), but a Covox is basically a set of resistors attached to the parallel port to act as a very basic D/A converter. So that might actually be an interesting thing to build for fun and an achievable goal with basic knowledge and a standard precision soldering iron :-)
