Re: Accelerator board? In those old days?

I just said that there is a 8514A *.vid driver for Dosshell that comes with MS-DOS 5 (but I guess it works on other versions too). The real Dosshell. Anyone used this really? ok looks it is from the style a predecessor of the win95 explorer app.

Re: Accelerator board? In those old days?

I don't think thats a rare find, according to the changelog of the vgadocs it was already in the initial release in Dec. 1991. So IBM probably unlocked their information after 2. Oct. 1991. As for a 8514A emulation in DosBox, I think DosFreak is right - who should use this? For myself I use the …

Re: Accelerator board? In those old days?

Hmm IBM probably kept their direct hardware access to the 8514A secret for quite awhile, so the programmer had to use the hdiload interface which comes on one of the 8514As Disks. (documented) In the vgadoc version 4 is a textfile included with the 8514As direct hardware register description. I …

Re: Accelerator board? In those old days?

"Any application that needs the Adapter Interface will ask for a TSR program called hdiload.exe. The hdiload.exe is a TSR program that loads itself into memory and stays there until the computer is rebooted or powered off. Although the hdiload.exe program only needs 18 KB of memory, it may be …

Re: Accelerator board? In those old days?

Ok I got it, there is a Adapter Interface Code Disk with a demo program and some example code for some functions. The code is put as some kind of subroutines in a TSR. I didn't needed that TSR yet and thought it is just for the Demo. Everything supporting a 8514A worked without it so far. But …

Re: Accelerator board? In those old days?

Ok I tried with the 8514A driver from Microsoft 1.01.10 that installs if I plug the mouse in the ps/2 port (even the most modern with USB -> PS/2 adapter works 8) ), but mj8514 shows the identical behaviour, it stays in textmode and if I move the mouse I can click on 'something' that makes deep …

Re: Accelerator board? In those old days?

I am not sure what the program requires except about 2 MB of EMS. The computer is this machine: http://mail.lipsia.de/~enigma/neu/ibmpc.html I haven't had any timer problems with this machine yet. I also tested with EMM386 from MSDOS6.22 and QEMM97. It is also difficult to imagine that the routines …

Re: Accelerator board? In those old days?

Elianda, could you please try to play Mah Jongg -8514- with your 8514/a? I'd like to know that it at least works on a real 8514 card. I tested it out and I could not get MJ8514 to work. It starts up, loads a bit from disk and then stays in textmode. Does it needs some time after startup until …

Re: Accelerator board? In those old days?

As for 8514/A there is some Driver for DOS Shell and Win 3.x available, others probably too. But is there some game with direct 8514/A support? I'am just curious because I own a machine with 8514/A. Booting up: http://mail.lipsia.de/~enigma/video/einschalten.avi Pinball Fantasies http://mail.lipsia. …

Re: Sound cards - from best to worst

I also think that the Software SB Emulation of the GUS was a really good piece of Software - BUT there are hardware issues you simply can not emulate in DOS. And the GUS was in terms of hardware design far away from a SB design. So a true SB as secondary card was mostly the best way to go. …

Re: Soundcards - which to choose, how to use... ?

7. What exactly are these (sound?) 'demos' that are mentioned here and there ? (for which Gravis cards apparantly are the best?) "Demoscene " etc... ?? Yes for Demos that are realtime calculated multimedia representation that push your old PC to its limits. Or considering that your hardware is …

Updated comparison of DOS soundcards

Hello, as you know for dos games the specific soundcard can make a big difference for the quality of the music. So we updated the Sound Card Comparison that was already mentioned in a thread here. It features now: Adlib, MT-32, Game Blaster, IBM Music Feature Card, AWE 32, Roland SC-55, Yamaha …

Re: My oldschool rigs

AWE32: The onboard ROM sounds really awful in some games, and there doesn't seem to be a way to load custom soundfonts under DOS. Also, the emulation doesn't work with games using a DOS extender. For AWEUtil it is true, that it's way of emulation grabs the NMI which does not work in protected mode …
