OK, so I'm still kinda new to the whole emulation thing, but I'm getting the hang of it, and my old DOS-fu is slowly coming back to me. I'm currently trying to get Designasaurus II running properly, because it's still one of my favourite games of all time - I learned to computer on the IBM P/S-1, and Designasaurus II was one of my favourite games for it. I found a copy on some abandonware download site, and it runs, but the sound isn't right. Instead of the cool music and varied sound effects I remember, I get a few basic tones and bleeps. I'm not 100% sure if this is an issue with DOSbox or the game files I downloaded. I still have the original IBM Discover & Learn II pack of games for the P/S-1, but I currently don't have anything that can read the disks apart from the P/S-1 itself, so there's no way of comparing the files on the P/S-1 to the ones I downloaded, but as far as I'm aware there was only ever one version of the game, so I think it's DOSbox. At a guess, I'd say DOSbox is emulating a less capable soundcard, as if the game was running on a system that can't handle the cool sounds. Is there a way to make it behave like an IBM P/S-1 soundcard?

Yeah, no offence or anything, but... not the most helpful post ever, really.

Maybe you know someone with a 3.5" drive that could read the original floppies for you?

Official DOSBox does not have PS/1 audio support; but there is an experimental build of an older version with such support that you could try: IBM PS/1 Audio Card.

Unfortunately not; I'm at uni so all I have access to is my laptop, and those of all my friends - all less than three years old, so no 3.5" drives anywhere - and the the computers in the labs, which transfer files via USB flash drives and across the network only. Other than that, there's our PC back home, but the floppy drive on that hasn't worked since the PSU exploded a few years back and we had to get a new motherboard (no idea why, but apparently the new mobo can't detect the floppy drive).

My grandad is currently working on getting his laptop (an ancient thing he used when he worked at IBM) to laplink to a more modern model. If he gets that working, then I can use the stuff on his laptop to talk to the P/S-1, and the stuff on the newer one to talk to my laptop, and hopefully work from there. It looks like we'll end up forming a chain of progressively more modern stuff, with the P/S-1 at one end and my brand-new laptop at the other.

I'll try the experimental version and report back. Thanks for the help!

I hope you get your original disks working.
The ps/1 audio build might be something else for you to try.

I have a legitimate copy of the game which has been paid for and everything; technically that means that copying it around counts as 'archival/backup purposes' under most licenses, provided that by the end of the process I don't have anything that wasn't included in what I paid for, and I haven't shared it with anyone else who hasn't paid for it.

Anyways, the laplink seems to be working, which means I now have system with a functioning floppy drive connected to a system that's modern enough to have a USB port, so I've copied the files from the original disks to a flash drive, and from there to my laptop. I now can say for certain that the issue is DOSbox's audio support - haven't tried the experimental build yet though.
