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!

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!

Let's test this Microchannel 3Com network card that I picked up for my IBM PS/2 Model 70 386 (with a 486 upgrade). Time for a quick 🧵 Image
Image
So, this card is a 3Com EtherLink/MC TP. As per usual, the Ardent Tool of Capitalism has a nice writeup on the card, as well as drivers! Looking at the drivers disk, it appears we have LAN Manager, NDIS, and Netware drivers. Pretty limited, but this is an older card. Image
Image
Time to get this installed. And of course, this is Microchannel, so, on powerup, the PS/2 is immediately angry. I did copy the "adapter configuration file" to my PS/2 Reference disk. Running auto configure, the card gets detected, and we can see the settings. Nice! Image

Last week, I triaged and repaired around 20 or so LTE 5000 systems that I picked up at the System Source swap meet. Today, I spent some time swapping around parts and "making them better." Let's talk about it briefly in a 🧵 here! Image
By far, the most common repair needed was screen sliders, latches, casings, and bezels. I spent a fair amount of time replacing and "placing" these based on what I had in stock, or based on spare parts machines from the haul. It's the little things that count 😂 Image
Image
Image
Image
Also, I had some very "yellow" keyboards that I went ahead and swapped out with spares. Might as well! Image

Last week, at the System Source swap meet, I picked up a bunch of interface cards! Additionally, I have this Microchannel network card that arrived in the mail. Let's test these cards out on the Pacman PC! Time for a long 🧵 Image
Image
Image
Image
As I was thinking about which PC to use to test these, the Pacman PC ended up being ideal. Its motherboard has ISA, PCI, and AGP support! Some of you might remember this CYS Tech CYSMBD-694X motherboard that I picked up from Ali Express a little while back: Image
Image
We're going to use Windows 98 SE to test. To ensure that I don't clutter my install with a bunch of driver install fun, I am going to make a backup copy of Win98SE that we will use for our purposes today. Image

Here's some good news for BlueSCSI/ZuluSCSI owners who want wireless networking in DOS and Win3.1x: Michael Brutman (author of mTCP) has taken my DaynaPORT DOS packet driver and greatly improved it! I'm using it to browse the web. Let's talk about how in a 🧵 here! Image
Image
First, some context: several months ago, I started down the path to get my BlueSCSI working in DOS, and made a very alpha driver to do such. As per usual, I then abandoned the project 😂
Then, Michael found out about the project, and greatly improved upon it! There is a beta version that you can find here: . Although the driver is currently beta, it is very well written, and is working great for me!github.com/mbbrutman/dayn…

I had a total blast testing my newly-acquired fleet of LTE 5000 series systems! Over the past four days, I was able to make 20 working systems from my haul of (I believe) 26 systems. Let's have a BRIEF outbrief in a 🧵 here! Image
Image
First, just LOOK at everything!! Everything you see here either will go in a system (HDD, FDD, CD-ROMs, battery shells), is a spare part, or a conversation piece (PCMCIA cards without dongles 😂). And, oh, for the six systems that contributed to parts, look at all of the screws! Image
Image
Image
Image
Here are the "failed" parts. Several failed or flaky mobos. Two bad processor cards. Several bad DC to DC cards. Only one bad FDD, which is miraculous. And of course, that one keyboard that took a lot of abuse, too much to repair. Image

Day 4 LTE 5000 (and probably some LTE Elite!) cleanup and testing. I'll just do highlight reel, I am sure you guys have seen enough at this point 😂. Let's do this! 🧵 Image
First, we have doubled downstream testing power 😂. Now let's talk about the system on the right... Image
So, as you can see, the screen is bad, but I think the effect is lowkey cool! Also, this system had a bad processor card and DC to DC card. That's been fixed. The HDD caddy had the logic board for a HDD and was missing the cover. Someone has been in here!! Image
