All the thanks should go to Jeff Leyda. It's still mostly his code. All I simply did was pushing it to GitHub, adding a few simple tweaks to enable it to work with more chipsets, adding some command-line arguments for volume control and unmuting, and figuring out how to assemble the code using the …

http://philipstorr.id.au/pcbook/book2/parallel.htm does it require specific type of lpt port? does it work with normal SPP one? how does its SB emulation work? does it require 386 cpu? How does it intercept port 220 writes? Yes, it requires a 386+ and it traps access to those ports. Ditto for DMA …

Man I wish someone could recreate this device (or at least it's board) with modern components. Both DS311 and DS301 are extremely rare, and that's unfortunate, because, unlike DS201, this is basically Sound Blaster on a parallel port. If you want sound on your old DOS laptop (or, perhaps, if you …

Speaking of -12V, would your adapter (or Matze's adapter for that matter) work on a system lacking a -12V rail? I'm looking for a solution that would work in a Tandy 1000 that would be powered by a PicuPSU, which, as I understand it, cannot provide -12V. This computer lacks integrated serial ports …

Does this card require -12V (as in negative 12V)? I'm asking this, because I'm considering a solution like this for my Tandy 1000 EX, since it doesn't have any serial ports. But I'd also like to use a PicoPSU to power that system, and the PicoPSU does not provide a -12V rail, as far as I've …

Oh, no! :( Time to open it up and see if anything other than the fuse let the smoke out. I didn't smell anything burnt out. What would be a visual way to check for such damage? You might not be able to spot such damage from the outside, right? Strange. When I accidentally flipped the 115/230 switch …

Nice Tandy! We had a Tandy 1000HX when I was a kid. I really wish I had appreciated old PCs at the time, because it was already quite outdated when I started using it. I hated the fact that it wouldn't play basically any game I could find. Bear in mind, this was the mid '90s, so the lack of Tandy …

Oh, it's feasible, and it's been done, at least for real mode games. For protected mode games, it hasn't yet been accomplished in pure DOS, but even those kinds of games can be made to work if you run them in a DOS session under Win9x using something like VDMSound. But it should be possible in pure …

Of course, there's also the possibility of just outputting things through the PC speaker, but I guess no one did that because the necessary signal processing would cause a huge lag in the gameplay, and also because it would sound like crap? Actually, VSB, the "Virtual Sound Blaster" written by …

Watch out for the polarity! Since computer hardware typically uses center-positive while analog audio equipment like guitar effects tends to use center-negative, this could be either. I hope it's labeled. Thanks for the warning, but it was indeed clearly labeled on the adapter, along with the …

Given how LGR got music and digital audio to work simultaneously in Simcity 2000 on Windows 3.1, it would seem like a software issue (perhaps in just the emulator) and not a hardware limitation. Again, this is a device that screams out for a reverse-engineering/recreation project. Also, I second …
