My friend Bill gave me a bunch of case lock keys! Back in the days of the AT standard for cases, keylocks were pretty common on PC clones, and IBM systems as well. Let's see how many locks we can open today. Time for a silly 🧵 Image
Image
First, the Gateway 2000 you saw in the intro post. First key I tried worked 😂 Image
Image
Next, let's look at the PS/2 Model 30 286. Not today, not happening, this uses a "more regular looking" key. Image
Image
Earlier today, many of you might have seen the thread on the Kehtron. Notice it had a key in it, this was not by accident 😂😂. So we are all set there. Image
How about the Gateway 2000 tower upstairs? No luck, strangely enough. I actually wonder if the lock mechanism is shot on this PC. Image
How about the DX4? First key I tried worked 😂 Image
And how about the PS/2 Model 70 386? Well, I actually had a key that fit, but wouldn't turn, no surprise there. Image
This little guy here already has keys, I bought this case new old stock, and it had keys! Image
Image
And finally, how about the Enlight AT case? Yep! It's good to go. Alright, this was silly fun, thanks for indulging me and for following along. Talk soon!

I already have too many PCs, but I had to have this cute little guy... and there is also a good nostalgic reason for having it! This 386 (now 486) PC needed a lot of work to get it running, let's talk about it in a 🧵 here! Image
Image
First, in case you missed it, here's the nostalgic reason. Kehtron is a part of my childhood. And this PC was available locally. The weather was also PERFECT yesterday for making an hour drive to get it and rocking out to some 80s tunes on the way 😂 Image
Image
Image
Okay, first order of business, I put this on the table and it was rocking back and forth. I soon discovered why! I didn't have a matching foot so I used a little bit of Goof Off to remove the adhesive. And PSA, like with most chemicals, always work in a ventilated area. Image

In my haste yesterday, there are TWO THINGS that I forgot to do and post about for this "eMachines" system. One is more important than the other! Let's talk about it in a brief 🧵 here! Image
First of all, before we get too far, recall that this isn't actually an eMachines. The original motherboard failed, and a Pentium III Biostar motherboard was put in to replace it, in what I am calling a "reverse sleeper"
So, what did I forget? Well, the first thing was to showcase the Wake on LAN capability! I installed a 3Com network card with Wake on LAN support. If we know the Ethernet MAC address and have a program to send a "magic packet", and the BIOS settings are right, we can use it! Image

I recently picked up this "eMachines" from my friend Bill to bring to the next local meetup and plop on the "free" table. I thought I'd spruce it up a little bit in the meantime, since, well, I enjoy doing just that 😂. Let's talk about it in a 🧵 here! Image
So, first and foremost, this isn't actually an eMachines. The original mobo died and it was replaced with a Biostar M6TWL and a Pentium III 600 MHz CPU. Does that makes this thing a "reverse sleeper"? 🤣 Image
Image
Given this, we have a little bit of work to do. First, unrelated, but the CMOS battery is dead. Also, there is a SATA Western Digital 120GB HDD installed, but that won't work without some sort of adapter, since the motherboard only supports IDE. Image

I recently received this Dell Inspiron 700m from my friend Bill. Originally a Windows XP system. I thought "maybe I could make this a mean DOS/Windows For Workgroups 3.11 system." Let's give it a shot in a 🧵 here, I bet we can get pretty close! Image
Image
First thing I did was to look in the BIOS. This system is a Pentium M 2.0 GHz with 512MB of memory. The optical is a CD-RW/DVD. Okay, this should be more than adequate for what we want to do here 😂. Oh... and look, we can boot from a USB floppy drive! Okay, let's do that. Image
Image
Image
First thing I thought I would do is to boot DOS 6.22. And... look at that, I even had the right drivers set up to detect the optical drive. Win! Image

I got a few items in the mail for my Compaq LTE 5000 laptops! A power adapter... and a bunch of Cisco Aironet 350 wireless network cards from a friend who bought like 50+ of them 😂. Let's test out the network cards and go through how to set them up in MS-DOS!! Time for a 🧵 Image
Image
Image
Before I get into the setup procedure, I wanted to inform that I do have a setup procedure for this on one of my old "crap film quality" videos (not that the newer ones were better 😂). If you want a video walkthrough, hosted by a younger RTC, go here! Image
To make these cards work in MS-DOS, we need an older firmware. It has become a bit scarce online, so I put it in my GitHub repo: github.com/cml37/dos-util…Image

Memory testing, final round! Mostly good news, but some bad news too. What happened? And... just how many memory spares did we end up having? Let's find out, 🧵 time! Image
Image
First, let's talk about the cliffhangers from last time. Both the CompUSA custom and the eMachines T2341 finished their round of testing, and are good to go! Image
Image
Now for some bad news. I ended up using the Pacman PC for a lot of PC100/PC133 testing, and when I put everything back together, the 512MB DIMM started to fail. Boo! So we are back to 768MB, but we got to use DIMMs that I bought a while back that were in my basement PII PC. Image
