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

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!

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 šŸ˜…. 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 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

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

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 šŸ˜‚ Image

I was recently doing some late night eBay shopping (which is always dangerous) and found this "SCSI hard card" for a GREAT price. I have a use case in mind, will it work for that? Let's have a look at it in a 🧵 here! Image So, anyway, this "hard card" has a Seagate ST01 controller card attached to a Seagate ST-138N 32 MB SCSI drive. It's a chonker! Pretty unreal to think they put this on a "hard card!" Image

My new 486 PCs are in need of a little bit of work. We won't accomplish it all tonight, but let's do a thing or two to tidy them up. Time for a 🧵. Image
Image
First of all, for the PC on the left, there is no heatsink and fan! I happen to have one on hand, so that is an easy fix! Image
Image

I recently picked up a BlueSCSI and also was gifted a 10,000 RPM Seagate Cheetah SCSI 4.5 GB hard drive. Let's test them out using the Rustbucket 2000 PC in a 🧵 here! Image
Image
So, for continuity sake, a few weeks back after we picked up the Rustbucket PC, I added a SCSI controller and HDD to it. You can read all about that here!

I have a few ATX power supplies to test. Going to test them out on the Rustbucket 2000. We will see how this goes! Image
Image
So far this Dell and FSP Group supplies have tested good. But the network card is misbehaving. Going to give it a shot of contact cleaner here in a minute. After all, this is the Rustbucket PC šŸ˜… Image

Time to connect this HP LaserJet 5L up to a Windows 3.11 PC and print something out! 🧵 Image After getting the software installed, I had a look at some of the options. Just look at the graphics representing 600 vs 300 DPI šŸ˜‚. Alright, let's print a page from Windows Write. Image

Another new retro PC for me? Yes! Let's have a look at this beauty: a 486 DX/33 in a 🧵 here! Image First, here's a look at the front and back. The case is made by Enlight. These cases are SOLID! No turbo button or seven segment display, but all is forgiven. Also, I need to find a few slot covers... or put some cool cards in this PC šŸ˜‚ Image

My new 486 DX4/100 PC is here, and I have been exploring a bit. This computer definitely had some strange problems, but I think I got them fixed... or at least I hope. Let's talk about it in a 🧵 here! Image This computer has a very nice condition Macase KS-330, which I why I wanted it. Compared to my other one, it is actually slightly different! Guessing they had different iterations. It may look to be slightly shorter but it is not, more on that next... Image

Okay people of X: you asked, so I delivered šŸ˜‚. I bought one of these three beige PCs we saw for sale at VCF East 2025 after a little bit of convincing. Let's find out whether or not I made a good decision in a 🧵 here. Image
Image
Image
Image
So, my first observation: this PC is RUSTY! Just look at the back of this PC and these screws. Hopefully we can fix that up at least a little bit. Image

My PS/2 Model 30 286 got a cool upgrade yesterday! It's now maxed out with 4MB of memory. Let's talk about it briefly in a 🧵 here! Image So, you might say "what's the big deal, doesn't this PS/2 Model 30 286 use normal 30 pin SIMMs?" Sadly, no. The pinout is different. This gentleman did a writeup on what you have to do to modify standard 30 pin SIMMs: john.ccac.rwth-aachen.de:8000/misc/ps2cache/Image

After some trial and error, I think I have my ITX-Llama w/ ATI Rage XL AGP video card (in a Dell Dimension 2400 case šŸ˜‚) running good and stable with Windows 3.11 for Workgroups. Let's go over the procedure in a 🧵 here! Image
Image
So, first of all, I carved out a 2GB FAT16 partition for use, using, yes, you named it, BootIt Bare Metal Image
Image

My ITX Llama motherboard is here! For those who aren't familiar, ITX-Llama is a Brand New DOS/Win98 Retro PC with AGP, OPL3, WAV Header, and Adjustable CPU Performance. It uses a Vortex86EX System on Module for its CPU. Let's explore it a bit in a 🧵 here! Image
Image
Image
First of all, I decided to put this in a Dell Dimension 2400 case, so first thing I did was to remove the Dell guts. Just look at that heatsink! I had to remove the standoffs for the heatsink too. This machine was ultra budget, and if my eyes don't deceive me, that's a Celeron. Image

I decided to install Windows NT 4.0 Workstation on my "new" Compaq Armada 1700. It went off without a hitch, except for one thing that definitely tripped me up! Let's talk about the install process in, you guessed it, a 🧵 here! Image
Image
So, first order of business was to find a suitable version of NT 4.0 Workstation. I see that someone had made a bootable ISO that includes the latest Service Pack 6a "baked into" the image. I'm going to use that! Image

Yesterday I posted a clip where I was getting ready for a retro party at the house later this week. Without fail, some hardware is bound to have a problem. And such seems to be the case for my Compaq Deskpro 6000, I think the HDD is failing. Let's take a look in a 🧵 here Image First, if you missed the video clip yesterday, here it is. This is "after the fact" of me fixing the drive. The Compaq is on the far right in the opening part of the clip!

I got a small cosmetic enhancement in the mail today for the Pacman PC. Let's get this puppy installed, in a 🧵 here! Image So, first of all, this was an eBay purchase. It took about an hour of mindless scrolling, which was patterned with hope, despair, and then finally elation which landed me on just what I needed! My "lowball" offer accepted too! An I/O shield for the ages

I got something fun in the mail today! That's right, I ordered a "new" motherboard to use with my Pentium III. Let's talk about in a 🧵 here! Image
Image
Image
So, this motherboard has allegedly been manufactured in modern times. But nominally, it is new old stock. It's a CYS Tech CYSMBD-694X, which is a clone of the Gigabyte GA-6VXC7-4X-P, with a few changes. I picked it up from Ali Express, it arrived in about two weeks. Pretty good! Image
