Ah, that. When we did that back in the day, the Old Ones, the ones who made us, called that the "deer in the headlights" expression.

Incredible low contrast font color in use there. Looks like about 0x002000 on pure black (per Mk-1 eyeball). What possesses people to go for these barely perceptible color schemes? .. a few minutes later .. Ok, the crazy low contrast was on

That 6809 bewitched my middle school self. Having already learnt Z80 assembly language, the 6809 just looked so much more elegant. It had index registers that were actually useful! It had position independent code! It could do multiplicatio

Yes, in the old systems, you'd get about 90 volts AC down the line to ring the mechanical bell ringer. Once saw a guy nearly fall off a ladder, splicing phone lines with bare hands. He thought the relatively low voltage was safe enough

That could probably be one failure mode.

I'm well familiar with 6502 shenanigans, but never really looked into 2600 programming before. Looking into that source file though, I got the impression that Atari mapped the I/O right into zero page? Kind of surprising, but I gu

>> If you ignore a dependency and try to fix it later, it will be more expensive. More time, more effort, more thinking. And it will require the same level of coordination that you tried to avoid initially. Would add that, if

What do you do with an impossible situation? You do what you can. This maniacal robot stove somehow evokes a sense of desperation we can instinctively empathize with. A fiction of an intelligent machine, facing doom, deserving of pity. Or a

Is whole-word dyslexia a thing? I thought I saw "Making Ferrite Inductor Cores", and got excited to learn DIY techniques for making custom shapes/blend cores. Still a good article, though.

It was about 110 chips on the original II wasn't it? Or maybe it's the II+ I'm thinking of. Anyway, it was a boatload of MSI parts.

My HP32s from ~40 years ago still resides on my workbench where I mess around with RF circuits for fun. It has no graphing capability and it's barely programmable, but that's ok, I keep an actual computer nearby for those sorts of

And "because I want to" is a legitimate reason, if it's my system. It's not up for discussion.

How about Realm of Impossibility? Every time someone mentions 'ROI' at work, for a split second I'm back at the old 64, not doing my statistics homework.

Yeah, that's a pretty awesome idea. The only critical spec for the transistor is the time to get into saturation, the actual pulse length coming from the propagation of the discharge of the coax segment from the collector end to the fa

Yes, someone cramming code into 4K ROMs in 1975 would very likely have been writing in assembly language. With you on that one.

Of course, MS seems to enjoy inflicting familiarity penalties on its established user base every couple of years anyway. After having your skills negated in this way enough times, the jump to Linux might not look so bad.

The best base, and I think everyone can agree, has and always will be 10, regardless of one's radix persuasion.

My hot take on that was "upside down 2? Nah, must be a really stylized 7"

Yes, what is really needed is a way to baseband a good swath of spectrum, e.g. in the neighborhood of 100MHz to 10GHz, so that conventional electronics can be used to study something more than simple low rate there/not-there activity.

I've seen some of the dreck that bubbles up on those 'copilot' responses on searches, with glaring inconsistencies on subjects I'm very confident with. If I didn't know better, and used such stuff, debugging would e

Helium can "actually remain liquid up to temperatures of 4 Kelvin, which doesn't require the extreme refrigeration technologies needed for things like transmons." Well. I had thought liquid helium was famous for being rather
