I would recommend my old Elf's keyboard[^]. Steel case, real key switches and lasts at least 42 years long.
But parallel keyboards of that sort don't grow on trees these days and I will need something more modern when I build 'Zwölf', Elf's younger brother. Just yesterday I was asking dumb questions about interfacing USB ports to an 8 bit computer, guess why.
But there is another way to get exactly the keyboard that you want and that lasts forever.
Tear out the encoder and the cable from an old keyboard. Then buy about a pound of cherry keyswitches[^]. Then design and 3D print keycaps and a case for the keyboard[^]. Layout, spacing and finish are entirely up to you.
You will not need a circuit board. The keyswitches snap into square holes in the case, but you will have to wire up the switches in columns and rows on the underside and then also connect the encoder you have salvaged from an old keyboard.
I might have to do a little more, like programming a PIC microcontroller with a suitable interface as keyboard encoder, but that's worth it. That keyboard can last another 42 years.

Good idea, switches are cheap enough.

Ahhh, steampunk! Hook that thing up to an Elf with Nixie Tubes[^] for the data and address displays.

Was de-bounce technology common in those days, or was that offered as an upgrade?

Very common. In hardware, not in software as it is done now. Tantalum capacitors, to be precise.

Why not buy a Cherry keyboard?

I heard they are especially good for cherry-picking with Git

Custom layout, custom design, and in my case another encoder/interface don't come off the shelf. I'm also going to need a hexadecimal keyboard
with address and data displays. Guess what, these encoders and display drivers are also hard to get. If at all, you get them from chip collectors with no guarantee that they are still functional and at a price higher than their weight in gold.
For me it's yet another job for PIC microcontrollers + key switches + 3D printing.

The keyboard in the video is just a plain straightforward design. You are absolutely free to draw up anything you like in a §D program of your choice and then print it. Of course you can get filament in all colors of the rainbow to print it. It's also not too hard to first prepare the surface with fine sandpaper, then spraypaint it in some color(s), apply lettering/decals and last a nice coat of clear paint to protect the decals and for the finish.
That's the good part about DIY. You can custom design everything as you like. For example, I might the numeric keypad with a hex keypad for the Elf.

I need a replacement for Microsoft's Queue<t> that allows for efficient indexed access to the items therein.
So I made one.
The trouble is, I don't know what to name it.
By default, containers in .NET are implemented on arrays (like mine is) so since .NET 2.0 things like ArrayList have simply become (Implied Array)List<t> - indicating array storage unless otherwise specified or there is no default array storage implementation (like with binary trees). The reason this comes up is because of things like LinkedList<t>
So while I'd name mine ArrayQueue<t> that itself is inconsistent with microsoft's naming conventions post 1.x
Queue<t> itself conflicts but it's what it's currently named. I've made the interface compatible but put it under a different namespace. I'm kind of leaning toward this.
Another option I considered was ListQueue<t> because it provides indexed access, but that doesn't really jibe with microsoft's naming conventions either.
To be honest, I wish Microsoft would have simply exposed the internal method they have in the reference source in order to provide indexed access. Seems silly that they didn't, since queues are ordered by definition, but whatever.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

Not if you namespace it.

Yeah I did namespace it. Still, conflicting with Microsoft's class name irks me a little. I think it can get confusing and icky if you reference System.Collections.Generic in your usings, which is really common (and I think by default when you create a new C# file in a VS .net framework project)

'cept it's a list. Collection doesn't guarantee order. List does, and provides indexed access, which my queue does.
I'll consider QueueList, thanks

When Microsoft extend something they usually (well quite often) add the suffix Ex. So how about QueueEx ? Does it not show up in Reference Source[^]?
|

They do that more in Win32 and COM than .NET
Usually with .NET they just stick new objects under a new namespace and try to name them differently.
