Alright, thanks guys. What I want to do is set up a dial-up server for personal use. Ultimately my goal is to get old game consoles that were in the early days of online connectivity, online, or at least connectable to a server, to play with friends. Yeah, it would be easier to get an actual...

I'm looking for a hardware modem. Is there a way to tell if a dial-up modem is hardware-based with a controller or software-based? I read that most, but not all, PCI modems are software modems, and that not all external modems are hardware modems, and then there are Winmodems, so I can't rely on...

I'm really sorry to bother you guys, but I just cannot figure out what I am doing wrong. I don't have my first incarnation of the computer I made back in 2018 to use as a reference anymore, sadly, and I don't remember much from it. Trust me that I got it working perfectly back then. @Hak Foo...

@Hak Foo Thank you for that. I'll study that in-depth. When I issue the command 0xCA to read the mode the controller is in, it returns a 1 on bit 0, indicating it is in PS/2 mode.

The keyboard is supposed to generate the clock signal. I tested the keyboard clock (on the inverting output of P26 on a 7406) and TEST0 with my logic analyzer. My idea was to see if the keyboard generated a clock signal when I push a key, but it doesn't. I tried multiple keyboards, but none of...

I should clarify that when I got the LED to work with an ISR, the 8259's IR0 line was connected to ground, and when I pulled the wire out, it triggered the ISR to light up the LED. Just wanted to clarify the keyboard controller did not trigger the interrupt. Thanks

Hello, I made an 8088-based homebrew computer back in 2018 that used one of these, and after some initial problems, got it working. I made a new computer based on the first one. Although this time, after initiating the controller self-test, P26 stays high. According to the datasheet, it expects...

I was required to wear ties when I worked at the computer repair shop back in 2010, and I hated everything about that place and working there. We were only allowed to wear ties of the owner's favorite sports team if we didn't want to wear dress ties. I specifically ordered patches of another...

The problem with HDMI is it's proprietary, and you have to pay royalties.

I used to be sensitive about sharing things I'm working on, or even asking for help, out of the fear of half the internet assuming that I did no research of my own beforehand. Or someone criticizing me because the code I wrote was far from perfect. It made me think twice about joining...

I used to watch that show all the time in the early-mid '90s :ROFLMAO: I loved the '80s styles of everything from back then, especially the cars.

I don't know why, but almost every engineer I worked with looks like those guys, from their posture, to their shirts, to their hairstyles. Not knocking any of them; just something I realized after looking at this pic :ROFLMAO:

Yeah, once. I had always just touched a common metal part of the computer before touching anything else, and didn't have a problem for a long time. One day, despite having a grounding wrist strap and not wearing it, I fried the touchpad of my parents' laptop when the screwdriver touched it. So...

That's awesome, thank you so much for your excellent help!

Awesome, thanks again! :biggrin:
