A few weeks back, we talked about PCI sound card compatibility in Windows 3.1x. And then I went and purchased an Aureal Vortex AU8820 sound card for like $10 bucks. Let's find out how well it works in DOS, Windows 3.11, and a few other OSes in a thread here!



Image

Image
Image
First, you'll be pleased to know that this sound card works with Hannah Montana Linux. Okay, enough of that already... for now 😂. Gosh, that color scheme is beyond atrocious and hurts my eyes. Image
How about Windows XP? Yep, detected and good to go! Image
Okay, off to Windows for Workgroups 3.11. Install was a cinch, but.. all I get in the program group is an uninstaller? Really?? No mixer? Yeah.. more on that in a minute.

Image
Image
Image
Things are looking good in the MIDI mapper, nothing to do there! All set. Image
If we look at installed drivers, we'll see there is a mixer. It just has no GUI. Fortunately, we can control the sound settings via system.ini. Under [Config\MixerSettings], I just changed all values from 32767 to 65535 to give "full volume" everywhere!

Image
Image
Image
Oh, and for the drivers, for the interested, I downloaded them from here! vogons.org/viewtopic.php?…
Alright, how about DOS? Fortunately there is a TSR you can use to make things work, included in the drivers above. However, it will probably lock up with newer systems. You can pull the "asp4dos" file from Win9x drivers to fix it though, details here: vogons.org/viewtopic.php?…
So, running asp4dos from the command line, we can see the card get detected. PRO TIP: If you install the Win3.1 drivers, you'd best take asp4dos out of autoexec.bat before you reboot, or replace it under the C:\WINDOWS directory before you do if you have a newer system! Image
So, for the most part, we are done. But there are two more problems to solve. The first is setting audio levels. I think with a vortex.ini file, this can be done with the asp4dos driver. But that was giving me trouble. So I downloaded SBMIX and it worked perfectly! Image
The next problem? If you run Win3.1x, the real mode DOS driver will uninstall. So after you exit Win3.1x, you need to reload it again. See this post I made today on Vogons that talks about the fix I used with a batch file! vogons.org/viewtopic.php?…
Anyway, there you have it. Now we can do fun things like play MIDI, MP3, and WAV files in Win3.x... using a PCI sound card. Thanks for following along! I'll leave you with a post I just did where we play an MP3!

I picked up this $5 USB to Parallel adapter at the System Source Swap Meet. I thought it would be cool to print to my HP LaserJet 5L from a modern computer! Let's talk about it briefly in a 🧵 here! Image
Image
So, here it is unboxed. Looks to be a decent length cable. Great! Image
Getting connected up is pretty straight forward. I'll use the HP Universal PCL5 driver and we'll set the port to be the detected "virtual USB printer port" Image

I picked up a $5 SCSI CD-ROM drive (or two!) at the System Source Swap Meet in hopes of "righting" a "wrong" on this PC. Let's talk about it in a 🧵 here! Image
Image
So, first, for those who didn't see it, here's everything I picked up at the swap meet. You can see the two CD-ROM drives I grabbed in the middle of the picture!
Now let's talk about the issue. The CD-ROM in the top of this PC is in poor cosmetic shape. It's a result of a retr0brite gone wrong that we talked about here: Image

I bought this $20 PC at the System Source Swap Meet since I really wanted an Enlight ATX case! I didn't inspect it close enough, and thus didn't realize at the time I was buying a project 😅. But I think it worked out in the end. Let's talk about it in a 🧵 here! Image
Image
Image
So, as you saw from the initial picture, this thing has seen the elements. As I look inside, I also see leaves and other debris. Makes me wonder if this was stored in a shed or something of the sort. Image
I took some time to strip out the components and clean the case up a bit. Okay, this is an improvement. Just don't look at the bottom 😂 Image

I picked up a "new old stock" ATX case at the swap meet today. I moved my ITX Llama motherboard over to it. Time for a quick 🧵! Image
Here's the back and inside of the case, and some included hardware. Look at that nice diagram that shows you where to use all of the screws and parts. Nice! Image
Image
Image
Image
Here's the box for it! I'll probably be keeping this. Maybe I will store the computer in this box when not in use, who knows! Image

I picked up the 386SX/16 system and the Dell NetPlex 486DX2/50 systems you see here (I didn't pick up the machine on top of them). Let's have a VERY QUICK look at them in a 🧵 here!
So, first, the 386SX/16. It powers right up, and has a VERY OLD Award BIOS. This BIOS version doesn't even support custom HDD params. It appears that the Western Digital drive inside is dead. But hey, it powers up, so that is good, right? RIGHT! Image
Image
Image
And next we have the Dell Netflex 4/50p. It's a little rough.. and very dirty. Its power supply is dead, but with some creativity, we got it to power up and boot! Image

I decided to build a retr0brite tub and try out a "test" project. It seemingly went pretty well. Let's talk about it in a 🧵 here! Image
Image
Image
Assembling the tub wasn't too hard. I used aluminum foil and spray adhesive to adhere it to the tub, or to adhere it to other pieces of aluminum foil. Shiny side out! After that, running the UV lights was easy since they had a sticky backing to them. Just plan ahead a bit 😂 Image
Image
Image
Now, word of caution with the spray adhesive: this stuff is really bad for your health. So, if you are doing this indoors, open a window or two. I also monitored air quality during the retr0brite process, and I feel like C02 levels went up in the house. As always, be careful. Image
