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
For lack of anything better to print, I decided to print out the first page of my webpage. Let's see how this goes. Image
Image
I started to print and quickly realized I needed a new ribbon. So I put in this genuine Panasonic ribbon.. and... wow! It is printing GREAT!!
Here's a comparison between the ribbon types. The ribbon type on the top is what was in there. I have a box of these "premium" ribbons, they are all dry. And the "good" ribbon was from the box on the bottom. Image
Here we go, the end result. Honestly, the quality is not that terrible! Image
Image
I thought I would print out the first page of my retrocomputing tracker spreadsheet too. Let' see how that goes... Image
This is making a very unique printing sound šŸ˜‚
The end result? Definitely a little hard to read, but it is legible.

Anyway, that was fun. I hope you enjoyed following along. See you soon!

Last week, I took my ISA to USB card out of my Tandy 1000 TX. Today it finds a new home in my 486 DX4/66. Let's get it installed and talk about it briefly in a 🧵 here! Image
Image
And before I get into that, recall that if you purchase one of these ISA to USB cards, they are pretty much good for mass storage devices only. Also, I did design a bracket for these a few years back if you need one! Image
When I cracked the case on this system, I realized that pretty much every slot is in use. I am going to remove this second serial port header for now, which freed up the bottom slot. All put back together, and this is what we see now. This is one power-packed 486 PC šŸ˜‚ Image

A few weeks back, I picked up this X10 home automation system for $5 at a thrift store. Who wants to explore some home automation using Windows '95? Let's have a look in a 🧵 here! Image
Image
First of all, what is probably most fascinating is that you can still buy this stuff from X10's website... in 2025. Go figure! Image
Let's explore what is in the box. If we look at the back of the box, we can see the accessories included. When I opened this up, the CD was missing, as was the serial cable. I bought the serial cable from eBay for about $10 and downloaded software from "The x10 Shop" online. Image

I recently picked up another AST Premium Exec 386 laptop... but not so much for the laptop, but really in search of some spare parts for my other Premium Exec 386 laptop. Let's talk about it and explore it in a 🧵 here! Image
Image
Image
First of all, unlike my Premium Exec 386SX/25 Color, this Premium Exec 386SX/20 is greyscale. It's still really nice though! I imagine that the color variants of these laptops was pretty rare, given the cost at the time. Image
One of my motivations for buying it was to get a nice power adapter. My aftermarket Delta Electronics adapter was looking worse for the wear, and none of my AST OEM adapters work. I think they need a recap (anyone want to help?) Image

I got my $50 HP LaserJet 6L in the mail today, and here it is. Let's have a closer look... oh.. wait a minute... oh no. Yea, not good. Let's talk about it, and some fun I had with it, and my NEW PLAN, in a 🧵 here Image
So, yes, the plastics on this printer were brittle, and it unfortunately wasn't shipped well. As soon as I saw the box, and the size of the box, I thought we might be in trouble. And, yes, we were. Just look at all of those glorious plastic pieces. Image
Image
Image
Image
Here's even more breakage. The front "bar" that connects the two sides together. And this internal mechanism too. Yea, this thing is cooked. Image

I think it's time to consolidate a few more retro PCs šŸ˜…. Going to start with my Tandy 1000 TX which already has a new owner! I did a little bit of consolidation into my 1000 SX in preps for sending it packing. Let's talk about it briefly in a 🧵 here! Image
Image
My 1000 SX had an XTIDE card in it, but the 1000 TX had a Silicon Valley ADP50 "hard card" with a 540 MB HDD. I decided to move that over to the 1000 SX. It takes up a fair amount of space, fortunately my 8 bit ISA network card is tiny šŸ˜‚ Image
Image
Image
This leaves us with a multi I/O card (the 1000 SX doesn't have an onboard serial port), 286xpress processor upgrade, ADP50 "hard card", 8 bit Ethernet card, and 8 bit SCSI card for the Bernoulli box. Sadly, no space for the ISA2USB adapter, so it comes out. Image

I got some 20MB Bernoulli disks in the mail today. Some of them are Tandy branded! Let's check them out and see how many will actually work... time for a 🧵 Image
Image
For the first disk, I decided to try one of the "older logo" Iomega disks. And... well... good old General Error decided to visit. This means that the disk has too many bad sectors to recover... and, yes, each disk does have reserved sectors, I covered that in a past post! Image
Image
Which past post was that, RetroTechChris? I thought you'd never ask. If you are curious about how reserved tracks work on a Bernoulli disk, here you go!
