      I don’t recognize this… Is it some sort of RF switch for connecting a computer or game system to a TV while still passing through the antenna signal? Why does it have two cables coming out the side?

        Yes, it’s for an old game console or computer.

        There were two common ways to connect to the TV, and this box supports both: Coaxial (still around of course) and that flat ribbon cable, which ends in two separate U shaped clips. The screws on the bottom are for the clips on the ribbon cable from the physical antenna likely mounted on the roof.

          I’m from Australia and I don’t think I ever saw a flat ribbon cable there. The RF cables in Australia mostly use Belling-Lee connectors (that you just push in) rather than F-type like in the USA (that you screw in), and that’s been a standard since the 1920s, so I don’t think there’s anything that predates it in Australia.

          Australia does use F connectors for cable internet, but that’s mostly a legacy network now.

          Edit: Apparently Australia did use them and I’m just not old enough lol

            Then you’re not as old as me. 300 ohm ribbon was pretty common in Australia, especially on crappy bunny antennas. You’d need a 300/75 ohm matching balun before feeding it into the TV.

            Ah, sorry I hadn’t even considered that it would be different in other places (just times) - I’m in the US, and those flat ones were present here at least as late as the 1980s and likely 1990s.

            Cable Internet is very common in the US, in fact the most common kind. (2nd is DSL) So the F connectors (didn’t know that name) are everywhere. Also still used for actual antenna connections.
            I am not sure if I have ever seen a Belling-Lee, but RCA used to be extremely common here until HDMI took over that role. (In fact RCA is what is on the switch box above to connect to the ‘computer’)

            We had 300 ohm ribbon back when we had VHF TV. When we went to UHF in the '90s we also changed to coaxial cable

            Coaxial cable works better at higher frequencies than 300 ohm, but needs shielding. 300 ohm doesn’t need shielding as any wave that hits it hits phase and anti-phase at the same time and has no effect

        Except that wasn’t a serial port, it was midi, and the reason it was on the sound card was because the input was analog.

        Your joystick was just two fancy potentiometers, and your soundcard decoded the voltage on the middle legs into a position.

        Soundcards handled joysticks because they had the fastest ADCs.

          They didn’t even use an ADC. They used 555 timers to produce a pulse. They measured the length of the pulse to determine the potentiometer position. Since there are 4 analog inputs, they typically used the 558 timer which is the quad version of the 555.

        Early PC only had 5 card slots, and the only jack on the motherboard was the keyboard. One slot is going to be used by a video card, one’s probably being used by a hard drive controller, one’s probably used by a parallel + serial card. Soundcards also included controller ports to try to save a slot.

          I thought sometimes they called them game ports (for the joystick.)

          I reasoned if you are installing a sound card, you are probably doing some gaming, so it made sense to sort of bundle those together.

            Its on the sound card because it’s a midi port. Its designed for connecting a keyboard (as in electronic piano). Most people used it for gamepads but that’s not what it was there for.

        Technically speaking, the joystick involved analog voltages to be converted to digital signals… And what else have ADC (analog-to-digital converters) chips? Soundcards, because ADCs are used to convert mic input, alongside the “line in”, both of which are analog voltages, into PCM signals, which are discrete (as in “non-continuous”) streams of bits. Something inverse happens for “headphone”, “speakers” and “line out” pins: a PCM stream coming from the sound driver is converted to analog voltages using a DAC.

        While other ports also happened to deal with analog<->digital conversion, a soundcard was particularly specialized at this job, alongside graphic (VGA) cards (VGA has lots of analog signals), but graphic cards were already too busy with thousands/millions of pixels and, well, with computation of graphics.

        Other boards aren’t so fitting for analog-digital job. For example: a NIC (Network Interface Card) already deals with digital signal so, theoretically, no conversion is necessary from/to analog. Parallel ports (those for printers) also natively deals with digital signals. Expansion cards with USB ports, same thing. And so on…

            Such nice keyboards. My Gateway 2000 was from 1991 and I believe they were pretty top notch at the time. It wasn’t until later that they went to shit. Through all the years and the massive amounts of mods, it didn’t fail until I retired it sometime in the mid to late 2000’s and only because home routers now did what it could do…faster and for a lot let power. It’s still in storage and I bet that if I powered it on today, it would boot.

            It’s little endian, so the beads on the far right are used to outnumber the big endian beads at the top on the woke left. After several computations, the middle section is just gone

                You know how some languages write left-to-right, and some rught-to-left? Endianness is that, for numbers.

                Or another analogy is dates: 2025/12/31 is big endian, 31/12/2025 is little endian. And 12/31/2025 is middle endian. Which makes no sense at all because the middle is, by definition, not an end.

          Yes, it was a nice little machine, the first computer I used at home. I shared it with some friends because our parents couldn’t afford it unless we pooled our money. Each of us would have it for a week then take it to the next kid’s house. In those days you had the option of buying it prebuilt or (cheaper) as a kit, and I still remember how excited I was when my dad and I came out of the electronics shop with a bag full of circuit boards, chips and keys that would magically become a computer when soldered together.

          The Acorn story is really amazing: a tiny hobbyist company that got a break when the BBC commissioned the BBC micro from them, that went on to invent the ARM chips that are in billions of phones and other devices now.
