They keep this 20+ year old laptop around because it has a serial port and every now and then that comes in handy.
You can’t really see it in the picture but the laptop is pretty thick and heavy.
In shockingly good condition too!
Though if you wanted to part ways with it, you can pick up an FTDI USB serial adapter for cheap. Though if it has a parallel port, hold on it it. Parallel ports USB adapters are just printer adapters and don’t work for general parallel port use.
USB serial adapters sometimes have compatibility issues. Hardware serial ports have interrupts, while USB serial ports can only be polled at a limited rate.
There are serial and parallel PCIe cards available that work much better than the USB adapters. Some modern desktop motherboards still have a serial port, but it’s usually a pin header that will need an adapter to connect to. There is also a nearly pocket sized laptop with a serial port and more connectors than many full size laptops have.
My B450 motherboard is pretty long in the tooth, but still firmly a “modern” component. I just added a Serial port via its built in header to use an old “Spaceball” for CAD. It only works in a few Windows apps, which is a shame because it’s completely a software issue and it works PERFECTLY in the apps that still support it. Linux as well, though I’ve only tried that via a USB-Serial adapter on my laptop.
PCIe can indeed be your friend! I got one with parallel port and no device to connect to. Currently looking for ideas.
The parallel port used to be used for connecting all kinds of homemade devices like logic analyzers, microcontroller programmers, frame grabbers, or just used for GPIO for reading switches and controlling relays. It was a lot easier to access directly from DOS than it is from Linux or newer versions of windows though.
Of course you could just connect a printer to it. I’ve got a thermal receipt printer that I’ve been meaning to write software for eventually. It will print out whatever I cat to /dev/lp0, but I can’t easily do any formatting or control the cutter that way.
I still have my old Lenovo X61T which is nearly as old. With maxed out RAM (4GB) and an SSD it is actually still quite usable (running Linux). I love its great keyboard, that’s the reason I kept it. At some time my kids discovered that it is still able to run Minetest at reduced settings and so it now is part of the occasional LAN-Party when friends are over. Opens my heart to see the old buddy right in the middle of action being used by a bunch of kids that are only slightly over half its age!
Why not just use a USB-TTY adaptor?
For some reason otherwise obsolete setups that live on for a specific purpose please me. But also you can get a USB to serial device on the cheap.
Edit: Just noticed the community this is in. So I guess… live on niche XP laptop!
I love xp. I wish that windows just kept the same look and overall style but with security updates.
Makes me think…Shouldn’t there be a Linux theme to accomplish that?
