Looks like a new PicoGUS firmware was released last month that has built-in WiFi support! Time for me to update the PicoGUS Femto on my Pocket 386 with the latest and greatest, and we'll do so in a 🧵 here! Image
Image
Image
So, first, I have actually been running a WiFi "developer" firmware build for quite some time, since around April 2024 or so. I put together a procedure on how to build and update the firmware at the time. You actually had to hardcode your SSID and password back then! Image
For the curious, the release notes for the firmware we are using can be found here (you'll see which versions of PicoGUS can support this firmware and the caveats. My device supports it and I am most interested in WiFi capability, so this works for me): github.com/polpo/picogus/…Image
So, to set the SSID and password, we will use PGUSINIT.EXE. Since I'll lose configuration after I update the firmware, I am going to use the network to copy this over to the Pocket 386 first 😂 Image
From there, update is a cinch. Hold down the button on the Pi Pico, connect the PicoGUS to your modern computer, and drag the new firmware over to the drive letter that pops up for the Pi Pico. That's it! Image
Image
Next, we'll configure with PGUSINIT.EXE. We can use the appropriate settings to set WiFi SSID and password, and then use the /save option to write the configs to the device! Image
Image
Piece of cake! Once configured, we can now browse the web in both Windows for Workgroups 3.11 (using NDIS drivers) and MS-DOS (using packet drivers and mTCP)! Image
Image
One thing I definitely need to do is 3D print the case for this thing. As such, I've sent the files out to be printed today, I should have the results in a few days! STL files for printing are in this directory if you need them: github.com/polpo/picogus/…Image
Image
Image
Anyway, that's all for now. The Pocket 386 is a neat little device. I do have "something" on order for it too, which we'll talk about when it arrives in a few weeks. As always, thanks for following along!

Okay, just wrapped another case swap, this time for my 486DX4/100 system. Naturally, I had a few problems to sort out as I went through this. Let's talk about it in a 🧵 here. Image
I ended once swapping from a "new" Macase that I bought recently that was in better shape. Despite being the same model, they are slightly different! One is a little taller and has some other differences. Funny how things that look so similar can be different 😂 Image
Image
Image
Image
Here you can see the inside of the DX4/100. I took a picture of the front panel connections and the order of the cards per usual. This will help with placement in the new case, perhaps 😂 Image

Time to do a case swap for my Pentium 233 MMX. We're going from one Enlight case to another! Here's the end result. I thought this was going to be easier than it was, let's talk about it in, you guessed it, a 🧵 here! Image
Image
Image
So, you might ask: why do a swap? Well, the current case for my Pentium 233 MMX is nice, but it is a little bit beat up. I found this poor computer in 2019 at Computer Reset being used as a "stepping stool" to get to higher shelves. And I rescued it! Image
Image
I thought to myself "okay, this is only going to take a few minutes, I'll just swap the cover." Well, despite looking the same, these two Enlight AT cases are actually different! So that plan didn't work out 😂. The cover doesn't fit!! Image

Okay, the first PC project is complete in support of my "slight collection slimdown." I've set up my Compaq Presario 2200 to "match" how the Presario 2100 was configured. Let's talk about it in a 🧵 here. Image
So, the first question people may ask is "why the trade up?" Well, the Presario 2200 is slightly faster, and is cosmetically in better shape. The 2100 is missing a FDD button and a volume button. Probably could be 3D printed, but that's ok.. a future project for someone else😂 Image
Image
The 2100 does have a slightly better condition top cover. I was going to swap it for the 2200... but... they are actually a little different, one is taller than the other! That's fine, no biggie. Image

I picked up this Parallel to USB adapter on eBay for $1 plus shipping. Let's check it out with my Panasonic KX-P2123 24-pin dot matrix printer! Time for a 🧵 Image
Image
So, the first thing I did was "unbox" it and throw that grody packing material away. Inside we have a cable, a floppy disk with drivers, and a manual. Nice! Image
I went into the "Add Printer" section on Windows 11 and chose Windows Update to populate the list of printers. And... look!! There's a driver for it. Perfect! Image

Recently, I announced that I was working on a packet driver for the DaynaPORT SCSI/Link, which will bring wireless support to DOS for select SCSI emulators. But did you know there are other wireless solutions available as well? Let's talk other methods I have used in a 🧵 here! Image
Image
Image
Image
First, and this one is tried and true, and I have used it the longest: the Cisco Aironet 350 PCMCIA cards. I presume you could also use the PCI desktop cards, but haven't tried it. You're limited to 802.11b and 128-bit WEP, but these cards work GREAT!
Next up is another personal favorite: PicoMEM. These cards emulate the ubiquitous NE2000 standard and bridge it to wireless! Amazing little cards that do a lot more than wireless networking too: HDD/FDD emulation, EMS memory, and USB mouse to name a few:

I'm behind on my testing... let's check out these new XTIDE Deluxe cards that I picked up from Monotech PCs that arrived this week and answer a few curiosity questions. Time for a quick 🧵 Image
Image
I installed a CF card into the first XTIDE Deluxe card, and installed it into an ISA slot in the Rustbucket PC. I also have a SCSI drive in this system. And.. as we can see here in my boot manager, BootIt Bare Metal, both drives are present! Perfect! Image
Image
Image
So, the question that I got asked about this card is: can you plug something into the CF card slot AND into the IDE connector? YES, yes you can. I proved it out with this Western Digital Caviar 22500 drive. We have a CF card, IDE HDD, and SCSI HDD now, and all are detected! Image
