I’ll see your raise, and up it:
My brother in Munchman, Alpine, and coding racist stuff out of the book.

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.

How are old you
You why are old

Don't buy copper from this guy, it's low-quality and your messenger will be treated with contempt.

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?).
Only if it's an AT keyboard. XT keyboards are incompatible and require active conversions. They use the same port.

I remember having a friend ask why my mouse connected to a s-video port.

Maybe I'm an idiot, but I ordered one when they announced it. I have 2 perfectly good C64s already but the CRT whine drives my dog and kid nuts, so looking forward to HDMI!
There are HDMI mods for the C64 as well.

PS/2
No, not the PlayStation.....
First one at home for me too.

So is this a more classic case of Apple's usual tactic making their things needlessly different to move more product?

I wanna say my first PC that I used a was an Amiga with similar i/o as this: I remember that mouse connector vividly.
You had an A3000? Those are not cheap today. Hell, Amigas in general are expensive.

TURBO!!!
wrote last edited by [email protected]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!

I'm using a PS/2 keyboard and trackpad right now.
Adesso ACK-540-pw if anyone is interested.
I'm using a ps2 keyboard because the usb one died.

Edit: I never used one of these, I'm just as old as one. First computers I used were a Macintosh 128k and an Apple ]|[, unless you count the TI 91-a as a computer and not a console, but that machine is older than me
I had a VIC-20, the predecessor to the C64...

Oh yeah? I raise you stacks of perforated pages and tractor feed accordions
I worked at a place using a dot matrix printer… in 2013.

I'm using PS/2 because USBHID requires a driver in the kernel and I don't have the RAM for that shit.

I’ll see your raise, and up it:
We had one of those in school. One per classroom. We had one educational game on it. Since there was only one, they would sit us down at it in pairs and we'd get 5m to play on it. I think I got to use it maybe three times in a given year.

wrote last edited by [email protected]ADB slightly predated (and is arguably technically superior to) the PS/2 mouse and keyboard interfaces, but Apple patented it and the only companies that licensed it were those making Mac peripherals.
edit: i forgot, NeXT also used it.

no it's a case of one set of ports being a decade or two older than the other
