Here's some good news for BlueSCSI/ZuluSCSI owners who want wireless networking in DOS and Win3.1x: Michael Brutman (author of mTCP) has taken my DaynaPORT DOS packet driver and greatly improved it! I'm using it to browse the web. Let's talk about how in a 🧵 here! Image
Image
First, some context: several months ago, I started down the path to get my BlueSCSI working in DOS, and made a very alpha driver to do such. As per usual, I then abandoned the project 😂
Then, Michael found out about the project, and greatly improved upon it! There is a beta version that you can find here: . Although the driver is currently beta, it is very well written, and is working great for me!github.com/mbbrutman/dayn…
The driver will work as a standard packet driver in DOS and can be used by mTCP and WATTCP. I have definitely showcased mTCP in the past here, it's amazing software:
For today's experiment, I wanted to run under Win3.1x. So, first I loaded the dayna driver, then winpkt as you can see here. My Adaptec SCSI card's drivers were loaded prior to this to make it work, naturally. Image
Next up, I installed and configured Trumpet Winsock. I set my IP address, DNS, and chose the packet driver vector (you'll see 0x60 in the previous screenshot). And just like that, we are online! Image
So, there you have it. I'm super excited about this! And if you want wireless networking in DOS, this is certainly an option you can try. Thx for following along!

I had a total blast testing my newly-acquired fleet of LTE 5000 series systems! Over the past four days, I was able to make 20 working systems from my haul of (I believe) 26 systems. Let's have a BRIEF outbrief in a 🧵 here! Image
Image
First, just LOOK at everything!! Everything you see here either will go in a system (HDD, FDD, CD-ROMs, battery shells), is a spare part, or a conversation piece (PCMCIA cards without dongles 😂). And, oh, for the six systems that contributed to parts, look at all of the screws! Image
Image
Image
Image
Here are the "failed" parts. Several failed or flaky mobos. Two bad processor cards. Several bad DC to DC cards. Only one bad FDD, which is miraculous. And of course, that one keyboard that took a lot of abuse, too much to repair. Image

Day 4 LTE 5000 (and probably some LTE Elite!) cleanup and testing. I'll just do highlight reel, I am sure you guys have seen enough at this point 😂. Let's do this! 🧵 Image
First, we have doubled downstream testing power 😂. Now let's talk about the system on the right... Image
So, as you can see, the screen is bad, but I think the effect is lowkey cool! Also, this system had a bad processor card and DC to DC card. That's been fixed. The HDD caddy had the logic board for a HDD and was missing the cover. Someone has been in here!! Image

It's another beautiful day here... and time to clean and test some more LTE 5000 systems! And since I am taking an extended weekend, we have time to do this. Let's get to work. 🧵 Image
So, first, the tarp earned its pay. It rained a bit overnight. Most systems did stay dry. No concerns here! I thought the tarp had a small hole in it. Indeed it did 😂 Image
Image
Image
Before we proceed, I do have a confession: late last night, I did pull one more system off the stack, clean it up, and try to test it. Sadly, it's dead. Oh well, we will deal with that later. Image

Ooookay, one more laptop today. A few folks have asked "how about the red laptop? Does it have a chance?" Well, I think I'd say "kindof, with some help!" Let's explore in a 🧵 here! Image
Image
Image
Initially, I started out with some Goof Off to clean off the paint. That damaged the screen cover's plastic. But I soon learned that would not matter. Because, well, here's the screen. Also, look at that nice red HDD cover. Paint on the keyboard too. Oh boy! Image
After some effort, I got the battery out. It was sealed by the paint. Now we can take a look inside. Lovely! Image

Shall we continue our LTE 5000 series cleaning and testing? I'm glad I covered them with a tarp, we had some condensation overnight!! This one is a LTE 5380 without any drives. It cleaned up nice and it does power up!! Image
Image
Image
Image
Okay, second one is a little rough. Cleaned up. Powered on once but won't power on again. Image
Image
Image
Next one! Cleaned up. Powered right up. A nice LTE 5380 Image

I've cleaned and tested three of my $10 laptops so far. And they are flawless!! Image
Image
Image
The fourth one I cleaned is a little rough (bad screen bezel, failing HDD, battery was taped in, and mouse pointer is bad) but hey it at least powers on! Image
Some of these are super gross... Image
