I have one more ISA sound card that I have been meaning to test, and it's kindof neat! Let's get it tested, time for a 🧵! Image
Image
First, here's the card. It's a Labway Labsound A00 card, with a Yamaha YMF719 (OPL3-SA3) chip! Now THAT's neat. Image
Image
Before I got to installing and configuring the card, I wanted to check the base address of my network card. It's set to 280h, to hopefully avoid any resource conflicts. Image
I copied over some drivers using the network, and the drivers we will use are Yamaha OPL3 SAx drivers. Let's get them installed! This install will get us configured for DOS as well. Image
Image
Image
So, similar to when I tried to test this card last time, it was cranky. I pulled the card out several times, moved the jumpers around, and eventually it worked (ultimately the jumpers ended up back in the original location... foreshadowing!) We get this config screen. Image
Image
With the card configured in DOS, let's listen to some Commander Keen gameplay. Sounds good to me!
Let's fire up Windows 3.11 again and have a look at the software. I like the mixer! Also, the readme is very helpful for explaining how the config utilities work. Apparently this card has "3D sound support too!" We have lots of options for recording too. Image
Image
Image
Image
Time to listen to some canyon.mid. I am not audio expert, but this sounds really good to me!!
Well, great, success! Card is nice and installed, and I took the other card out for now. Great, I'm happy! As always, thanks for following... HEY, WAIT A MINUTE! What have we here?? I booted up again, and.. card not detected. UGH. Image
Image
Well, the good news is that I think this is solved...I took some rubbing alcohol to the gold contacts on the card, and I think we are good again. But I will keep this card in this PC to monitor it, to see if it keeps working. Thx for following along!

Last week, I started some ISA sound card testing. Being the retro masochist I am, I picked up an IBM MWave-based sound card at our local swap meet a few weeks back. During our last testing session, I couldn't get this to work. Will we succeed today? Let's find out! 🧵 time! Image
Image
So, first, let's say this much: the MWave concept was cool with its use of a DSP. I benefitted from this back in the day when I upgraded my Dad's Thinkpad 755CX modem from 14.4 to 28.8 with a software upgrade! It knocked out sound when the modem was in use, but, well... ok 😂 Image
Image
Image
Alright, enough of that. So, first thing I had to do was move my NE2000 compatible network card to a new IOBASE of 0x280. That freed up 0x300 for the MWave card's MIDI. Image

I picked up four hard drives from the free table at our Northern Virginia meetup today. I am sure they are ALL going to work perfectly (foreshadowing). Let's talk about it briefly in a 🧵 here! Image
First, let's go with the Western Digital Caviar drive. I popped it in the Kehtron desktop PC I had. Funny enough, that system already has a Caviar 22500, so on bootup, we see "twins" 😂 Image
Image
So, yeah, okay, I tried formatting the drive. And things didn't go so well. I was going to grab my SpinRite 6.1 disk for fun, but recalled that it doesn't run on a 486. Oh well, this drive is toast anyway. Pour one out for it.

I did a component swap on the Enlight siblings today. I also went down a rabbit hole that I would never have anticipated doing, but it turned out well. Let's compare these cases, look at the components swapped, and the diversion I took, in a 🧵 here! Image
Image
First, let's compare the front panels. Pretty similar, except the USB headers on the new one. Image
Image
Next, we have the 5.25" drive install mechanism. The "new" case is toolless, and the "old" case requires rails. Which... well, people tend to lose. The toolless install is a LITTLE rough around the edges, but it works! Image

I've gotten a few items in the mail over the past few days. Let's test them out, and also improve the aesthetics of the re-enlightened PC. Time for a 🧵 Image
Image
Image
First, we have this Sony CDU701 32X IDE drive. I put it in the retr0brite bin in the wee hours of the morning, and when I checked it out when I woke up, it looked great! Since it tests out good, it is going in this PC for good! Image
Image
Image
Next we have this Acer 650P-047 50X drive. Unfortunately, it is flaky... it even opens and closes the drive door incorrectly when I try to open it. This was an eBay purchase, so back it goes! Image

I have a bunch of ISA 16-bit sound cards to test! Let's test them (or at least try to test them) and select one to put in the new Re-Enlightened PC. Let's go! 🧵 Image
Image
Image
Before we get too far into this, I copied over DOS/Win3.1x drivers that we will need for the five different sound cards, and also made a backup of my DOS/Win3.1x partition, since we'll most certainly be screwing it up. I also copied over some games to test in DOS. Image
Image
Image
The first card we are going to test is one I have set up before: A MediaMagic ISP-16. I started to install drivers, and realized that they HAD to install from a floppy disk, so I copied them there! Image

I have a few updates for the Re-Enlightened PC that I built yesterday! Let's talk about them in a 🧵 here Image
First of all, I completed a retr0brite on the combo floppy disk drive. I think it looks a little better now! Still not a perfect match, but close enough! Image
Image
Second, I swapped out the Trident PCI video card for an S3 86C75 Virge/DX PCI card. I actually tried two Trident cards, and they were both being a pain. This card looks SHARP! Very pleased with it. Image
