Okay, time for the Pacman PC components swap! I swapped over the HDD enclosure and the Zip 100 drive. Let's talk about it in a 🧵 here!


Image
Image
Image
Here are the components I pulled out of the Gateway! I do have a future plan for the ones we don't use today, we'll talk about that here in a minute!
Image
Image
Zip 100 drive is in the slot. Now I just need to find some screws. Luckily I have a few 🤣
Image
Image
And I did pop out two slot covers. I labeled them for future safekeeping and ease of pairing with this PC! Image
With all devices installed, I powered up and went into BIOS. OOPS, for the second time today, I have a jumper issue. I took out the CD-ROM drive and jumpered it to be the slave device. That took care of it. Also, my boot manager detects the two hard drives and Zip 100 drive!

The sound card that I pulled out of the Gateway is a CT5806, a Sound Blaster 128 PCI Digital. I like this card because it works in DOS... and that is why I am keeping it for now! The drivers for that are here: easymamecab.mameworld.info/html/snddosdr.…
Image
And the final card I pulled out is this FutureTel PrimeView NS 320 MPEG capture card. I had three or four of these at one point! I was able to locate drivers for it and use it in the past! I documented it in an old video of mine.
Image
I need to see if I can find the system requirements for the MPEG card! The web page for this card is on the Wayback Machine, which is where I found the drivers too! Wonder if it will work in my Pentium Pro. Anyway, thx for following along as always!

I picked up a bunch of ESDI hard drives at the System Source Swap Meet. These were on the free pile! I figured at least one of them should work in my IBM PS/2 Model 70 386... well, perhaps. Let's find out! 🧵 time! Image
First, we have to start with the base case. Will the system start up with my 60MB ESDI drive in it? Yes. Good! Carry on!! Image
First drive in, but system is detecting a configuration change. That can't be good. Have a listen to the drive. Yeah, I think this one is a goner. I ran system configuration, and yea, not even detected. Oh well! Image

I spent some time swapping around components and upgrading one of my new LTE Elite 4/50CX systems! Let's talk about it! Time for a quick 🧵 Image
So, first of all, this system has a 486DX2/50 processor. But some of you might recall that I bought a parts system at the System Source Warehouse sale. It's in terrible shape. But.. it has a 486DX4/75 processor! I swapped it in, and now we're cooking with gas! Image
Image
Image
Image
The next thing I tried was swapping the screen from the doner parts machine to my other LTE 4/50CX since it has a line across the top of the screen . Unfortunately, the backlight is dead. Oh well, we tried! Image

Well, after swapping parts around, I have four decent Armada 7700 series systems! They are not flawless, but some of them are actually pretty decent! Let's talk about this morning's adventure in a 🧵 here! Image
Image
Image
So, my primary goal was to load system setup on these and see what the specs are. I started with the floppy drive. But these have the dreaded Citizen W1D drives. Ugh. Luckily there is a solution! Image
Image
I went over to one of my LTE Elites and popped out a OpenFlops W1D, which is basically a Gotek replacement for the Citizen W1D. And, well, these work seemingly great! I was able to boot DOS off of an image file. Image

I posted the first picture you see earlier in the day, and promised all of you an explanation. Well, I don't have one 🤣. So, I guess we can just test these Compaq laptops out instead. And... things are going well, except for a couple of my screwups. Time for a 🧵 Image
Image
Image
Alright, here we go, all of the laptops on the desk. Yes, the one LTE Elite on the right is thrashed, I paid $3.33 for it, hoping to get some parts! Image
Let's see what we have. Here it is, all torn down. Sadly, it doesn't power on. Oh well. Maybe the screen is good! We'll test that another day. Image

Alright, I'm back home from the System Source Swap Meet and Warehouse Sale. You might have seen my video clips earlier, let's post some pictures! Time for a 🧵 Image
Image
Check out this Power Macintosh in its original box. Now, based on what was in the warehouse, there was some stiff competition for this. I don't think it sold. Image
Image
Image
What would a swap meet be without a free pile? The pile did ebb and flow a bit (I think I have more pictures too, we'll get to those), but here is what I saw first thing in the morning! Image

Recently I updated the BIOS on my Compaq LTE 5400 to support large hard drives. However, this ended up causing a few other issues I had to solve. Anyone remember battling with DOS conventional memory and dealing with driver issues? Well... here we go! 🧵 Image
As I noted in the opening post, I upgraded the BIOS. This upgrade basically adds XTIDE to the system to support large hard drives. But, XTIDE is what is known as an option ROM. Which means that it is going to take a slice of the "upper memory area" in order to work. Image
Image
Image
This caused two issues for me. First, my PCMCIA network card tended to "live" in the region that is now used by XTIDE. Okay, no problem. This computer uses SystemSoft software to manage PCMCIA. Through trial and error, I moved its memory region elsewhere. Network card fixed! Image
