Great times. I remember playing something like this on a telnet server on '96, I think they are still some servers running today: https://www.freechess.org/Help/HelpFiles/addresses…

> But the author does themselves no favour by including this incorrect tidbit in the article: As I undertood it, that tidbit comes from Sandisk and probably targets Windows user. I…

> ...but I think the way the original VT52 handled scrolling was that it incremented a register which it used for the index of the starting line That's exactly right, pretty cheap …

A couple of years ago I did a vt52 emulator with an fpga, no processor at all (not even a soft-processor). Just regular ram and sequential logic. You can use a simple processor for…

But once you get pretty good at it you can choose to start with a suboptimal word, like a handicap.

It doesn't matter what option he was looking for (maybe nearby share, messaging, etc as shown in a latter image). The point being made is that it wasn't in the first screen and the…

People stay in cities because there are more opportunities there and they have a support network. I have a property in a very small town around (1000 inhabitants, about 130 kms fro…

While I agree with you (having just played a couple of nes games on an original console a couple of hour ago) aren't you missing the point of the quote? This is better than the ori…

> Spreadsheets and FPGAs are two places where there's no focus on a "program counter". I'll give you spreadsheets, but while it's not the "focus" you will very often see softcores …

I think you are missing the point. Doing that for one machine for yourself: easy, cheap, maybe even fun. Doing that for 5-10 unknown machines for other people to use in a class... …

It's not that easy if everybody is doing it in a different way... I prefer both control keys next to the space bar, then alt/meta, then super. I have a short spacebar and can do bo…

I was just thinking about this today. I am currently forcing myself to work on TCL for a small project (I've only used it casually before). Coming from lisp I can appreciate some a…

Why not the other way around? What's the point of using a dual core 32bit with hundreds of K of ram for, let's say, a simple automated irrigation controller? There are applications…

> I wholeheartedly agree with all of the above—assuming that you are your own client. Yes, I was talking from that perspective. Just to remember people that not everything has to b…

Sorry I guess I just read too quickly and missed the part about using memories as BIG lookup tables. I am with you on this one.

> Don't crash That's good advice in any vehicle :) I think you are missing my point. I only say just because something is available doesn't meant you should use it. Life is not alw…

Sometimes people make simple things very complex. As long as he regularly backup his work he could be using an old machine with no issues. Why does he need to backup a vm image, wh…

Most fpgas are exactly mini async srams used as LUTs. The old MachXO series I'm working on actually allows using the luts as 16x2 bits RAMS (synchronous, single port or pseudo dual…

Actually more than one, and new projects are started everyday to RE more architectures as we gathertools and knowledge from previous efforts. While the newer higher end fpgas are s…

Ah, totally forgot about these. My father saw them extensively in x-ray generators (which may reach over 100KV for some applications...)

As a matter of fact you can do it with just one... That would be a half wave rectifier (not that good, you miss half the cycle). You can also do full wave with just two, but you ne…

What I took from the article is that it's useful when combined with type inference. So in Zig you could do: var x : u8 = 5; var y = @as(u32, x); OR var x : u8 = 5; var y : u32 = x;…

Yes, but it could also be a single program with commands. I think Jeff Raskin talked about something like this with Archy. You could also think about the emacs paradigm extended to…

or the lisp machines

Adding the numbers is not the problem, the problem is what the numbers represent, where do they come from (if they come from only one place...) where and for what are they needed. …
