          On the Amiga’s 40th birthday I brought the old Amiga 500 out of storage to the dinner table and we had cake. Just realized I should do the same with the Atari ST, for more cake. I think my family tolerates me because of the cake.

        What is that Acorn? I don’t remember the BBC having an “Acorn Bus Extension”, and it looks too narrow to be a Master…

          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.

          Yeah, if you can keep them running, they’re surprisingly efficient. And they hardly ever jam. But all the printouts look like garbage and feel like you’re trying to interpret ancient runes.

        The first three Macs had this jack in the front for the keyboard and a PC-like serial port in the back for the mouse. With the Mac SE and II, the switched to ADB, which looked like a PS/2 port, but you could daisy chain your mouse, keyboard, and other inputs like tablets or joysticks all into one jack in the back of the computer.

        Way back, there were some rare keyboard / motherboard combinations where the motherboard couldn’t detect there was a keyboard attached unless a key was pressed on it. That message was for those people with those combinations.

        You pressed F1 and the computer would be like “my bad, there is a keyboard there, thanks for your help”, or rather it would just shut up and boot.

        The message could have been different but it had to fit in a small amount of BIOS ROM, so we got stuck with the one that covered all the bases the best, and unfortunately, most people who saw it didn’t actually have a keyboard plugged in, thus, irony.

        The error message sounds bad, but it was actually a good thing. A better phrased error message might have been “Keyboard missing. Connect a keyboard and press F1 to continue.” But, in the early days every byte mattered.

        The system wouldn’t work without a keyboard, and if you get further into the boot process you might not be able to shut down cleanly if you didn’t have a keyboard attached. That error message gave you a chance to attach the keyboard, or to troubleshoot why the keyboard wasn’t being properly detected (like the plug got bumped and wasn’t making good contact anymore).

        It was annoying when the lack of a keyboard was intentional. Like, you wanted to use the machine as a server. But, AFAIK you could disable this check if you knew the machine was going to be a server with no permanent keyboard attached.

          I was always told that you shouldn’t (dis)connect a keyboard when it was on because it could short circuit and fry something. This was before USB, of course.

            Starting around the time of USB, they started designing plugs so that the parts of the plug that carried power were slightly longer than the parts that carried data so that as you plugged it in, the power connected before the data. That wasn’t something that was done with old connectors. In those, everything was the same length, so everything connected at once.

            OTOH, USB is a more complicated protocol than the old serial / keyboard protocols. I think generally systems were built well enough that you were unlikely to “fry” something by plugging in or unplugging something like a keyboard while it was running. Especially because the keyboards used low current and low voltage. And computers used big discrete resistors, capacitors, etc. back in those days. But, you could get some bad data on the keyboard line.

              Interesting stuff about the plugs, thanks.

              I did quickly fact-check myself after posting and my brief reading suggested that it was possible to break the port, motherboard, or the peripheral, but that it was rare and more likely to cause corruption and/or crashes.

              E.g. some anecdata in https://superuser.com/questions/172420/is-it-safe-to-hot-swap-a-ps-2-keyboard and https://electronics.stackexchange.com/questions/50883/why-some-computer-peripherals-should-not-be-disconnected-without-turning-off-thi

                and more likely to cause corruption and/or crashes.

                Yeah, that’s the neat trick they basically solved by making the power connectors longer. If everything connects at the same time, you connect the data lines while power is still coming up, meaning there’s a few milliseconds of data that you can’t really trust. If the hardware and software on the other side is designed to “trust” the data from the keyboard, who knows what could happen. Probably not something that breaks the hardware, but definitely something that can result in unexpected data for the software.

                But, just by adding a few millimeters to the power lines, you give a few milliseconds of power getting stable before data is attached, and that’s enough for things to be nice and stable.

      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

      IIRC, that’s electrically compatible with the smaller, more fragile PS/2 connector. The adapters are just wiring it down to the smaller connector (and maybe some impedance matching resistors?).

          Should also work with a USB to PS/2 so you can use it on a modern machine if you want. Some modern keyboards are still backward compatible as well. I have a USB keyboard I can use on my old Din machines using two adapters.

        The “Turbo” function was a masterstroke of marketing.

        The actual function of the turbo is to slow the machine down, so it can be compatible with older games and software that ran too quickly on those newer systems.

        Of course calling it a “slow down” button wasn’t very sexy, so just flip the function around and label it turbo instead!
