🎄💾🗓️ Day 4: Retrocomputing Advent Calendar - The DEC PDP-11! 🎄💾🗓️

Released by Digital Equipment Corporation in 1970, the PDP-11 was a 16-bit minicomputer known for its orthogonal instruction set, allowing flexible and efficient programming. It introduced a Unibus architecture, which streamlined data communication and helped revolutionize computer design, making hardware design more modular and scalable. The PDP-11 was important in developing operating systems, including the early versions of UNIX. The PDP-11 was the hardware foundation for developing the C programming language and early UNIX systems. It supported multiple operating systems like RT-11, RSX-11, and UNIX, which directly shaped modern OS design principles. With over 600,000 units sold, the PDP-11 is celebrated as one of its era's most versatile and influential "minicomputers".

Check out the wikipedia page for some great history, photos (pictured here), and more -

And here's a story from Adafruit team member, Bill!

The DEC PDP-11 was the one of the first computers I ever programmed. That program was 'written' with a soldering iron.

I was an art student at the time, but spending most of my time in the engineering labs. There was a PDP-11-34 in the automation lab connected to an X-ray spectroscopy machine. Starting up the machine required toggling in a bootstrap loader via the front panel. This was a tedious process. So we ordered a diode-array boot ROM which had enough space to program 32 sixteen bit instructions.

Each instruction in the boot sequence needed to be broken down into binary (very straightforward with the PDP-11 instruction set). For each binary '1', a diode needed to be soldered into the array. The space was left empty for each '0'. 32 sixteen bit instructions was more than sufficient to load a secondary bootstrap from the floppy disk to launch the RT-11 operating system. So now it was possible to boot the system with just the push of a button.

I worked with a number DEC PDP-11/LSI-11 systems over the years. I still keep an LSI-11-23 system around for sentimental reasons.

Birthday Present

Fem!Reader x satosugu

Summary: You and Suguru decide to surprise Satoru for his birthday

Warnings: choking, , degrading, oral (F and M receiving and giving), fluff, sexual content, breeding kink, edging, spitting, praise.

I was late by 7 min give me ssome credit okay😭

(Not my art) its cute and silly though

The air in the room is heavy. The tension is thick enough for you to grab at it, as pants and whimpers, even moans pass through the pretty pink lips of the man with lidded blue eyes. The pleasure was intense for him as you and the gauge eared man worked on edging the man above you. Admittedly, it was his birthday and you two shouldn't be teasing …edging him so hard but the man above you was a masochist who enjoyed this way more than he should.

“Hah~ so fuckin good~” Satoru moaned out, his grip tightening in your hair as you bobbed your head up and down his shaft, his tip hitting your throat as is slightly contracted around him causing him to spill out a string of curses and bring you down on his cock deeper. You slightly gagged before being able to take it down easily. The tip of your nose touching his trimmed pubes as tears spilt past your eyes and an enormous amount of spit falling from your mouth, it dripped down your chin on to your exposed chest while Suguru groaned while sucking on Satoru's balls and graciously accepting any of your warm saliva that came his way.

Satoru watched the mess below him that unfolded intently, his body twitching in pleasure just as much as his cock, buried deep in your throat. “Hey~ Sug- ngh! Fuck~! Suguru…wanna….wanna see you eat h- ah~ her out- fucking shit~!”

A sudden soft popping noise rings in the room as Suguru stops sucking and looks up at Satoru with lustful eyes, “as you wish, birthday boy~” he growls lowly before hoisting you up and off Satoru's cock for a minute by your hair, a thick amount of saliva and pre coats the white haired man's twitching dick and drips down to the floor while a strand of saliva connects from your mouth to his tip. This causes both men to groan. “You made such a mess, baby. Drooling everywhere like that. Good fucking slut~ Right Suguru?” He cooed

The man responded with a nod before speaking “so damn messy, might get her to clean it up if she likes making it so much~”

He chuckled.

You finally piped up, your voice hoarse from gagging on his cock, “don't tease~I wanna feel good…please just wanna cum~” you whined, slightly humping your heel.

Suguru only kissed down your neck to your collarbone while using his free hand to pinch your clit, making you jolt and moan loudly before Satoru caught it between his lips, kissing you from your senses as he shoved his tongue past your lips and you continued to let out little whimpers and moans as they both teased you.

Satoru pulled away to give you time to breathe and leaned back as he observed how desperate you were getting while you helplessly humped yourself on to Suguru's hand and begged for more than just his relentless teasing.

“Oh c'mon now don't taunt her anymore, at least let her cum on your face. K?” The white haired man cooed.

Suguru finally lets go and moves his hand and hoists you onto his lap as he laid down between Satoru's legs, not caring as the mixture now drips on him and wets his hair. He then pulls you over his face and forces your hips down before Satoru tugged at your hair as if to hint you to start sucking him again.

You whimpered as you engulfed his length again. Bucking your hips against the other man's face as he groaned in satisfaction, his tongue flicking up and down your slit with broad stripes up your labia and thinning his tongue out to tease around your bundle of nerves causing your thighs to shake and attempt to close shut only to be held in place by the grasp of Suguru's strong arms. You moaned on Satoru’s cock causing him to buck his hips at the vibration and slam you down a little harshly as he finally finished down your throat and a breathy groan left him.

“Good job baby….just take- hah~ take it all down your throat. Mmm~ good girl~” he praised as you felt ropes of his warm seed shoot down your throat and you continued to hump Suguru's face as needy moans drew from you and your eyes slightly rolled back in pleasure and excitement.

Suguru slurped you down greedily, your juices coating his face as he groaned at the taste and allowed chuckles to leave him as he felt your legs clench every time he made a noise of enjoyment. “Ywu reamt sm gwwd whem I ewt yowr pwuwwy~” he groaned between your legs before prodding his tongue into your clenching hole and nuzzling your clit with his nerves making you squeal and shoot your hands downwards, tangling your fingers in his hair and tugged on black strands; whining as you did so while searching for some sort of semblance; rutting against him desperately. He groaned again, shoving his tongue into your leaking hole as deep as he could, enjoying how needy you were. “swo fwckin nwedy…cwm onw mw bwaby” and just like that the dam broke as you gasped and moaned uncontrollably.

Satoru cooed at you as he watched you ride your orgasm out on his boyfriend's face. “There you go atta girl, your so fucking pretty~”

You find your lips against his as he greedily kisses you, groaning as he tasted remnants of his cum in his mouth with his sharp tongue. Suguru finished lapping up your orgasm with a satisfied sigh before allowing you to shift down on his abdomen carefully so as to not disturb your kiss. “Yo Satoruuu~” he purred, “wanna taste her~?” Satoru pulled away from your kiss, his glowing blue orbs gazing lidded at yours before he hums. “Come sit on my lap baby~” You scrambled up shakily and Satoru helped hold you and settled your down on his lap, his hands instinctively toying with your breasts and pinching your nipples before he motions to Suguru to him, listening to your sweet moans. He kisses the man harshly, exploring his mouth and groaning as he savored the mix of Suguru's spit and your cum. You watched and whimpered desperately, humping Satoru's thigh.

A strand of drool connects their lips as they pull away from each other and Satoru's the first to speak. “heh~ think this birthday boy's dick wants a taste of our little slut here~?” he coos before wrapping his hand around your throat making you whimper. “yeah pretty girl, you want that? Want the birthday boy to take you down on his cock with Suguru?~”

Suguru hummed in agreement and bit your shoulder hard enough to make you moan in pain and pleasure despite Satoru's hand squeezing your throat, depriving you of any other noises or stable breathing. “You look so gorgeous, but you'd even more gorgeous if you were fucked out~.” Suguru whispered into your ear and nibbled your ear lobe. “C’mon hun, beg for it like the sweet girl we know you are~.” You bite the bottom of your lip before pleading for it. Satoru wasted no time, getting his cock lined up with your entrance and allowing you to guide yourself down his dick. A filthy squelching noise is heard in the room as you slide down Satoru, gripping his shoulders for dear life and moaning and panting his name erratically. Suguru was using some of your slick and leftover saliva to coat his cock as he rubbed his girth against Satoru and you.

You whined at the feeling, already feeling so full with Satoru, and you're unsure if Suguru would even fit along with him. You quickly realized that he'd find away as he managed to push his tip through the tight squeeze with a groan. The slick helped him push into you slowly as Satoru moaned, feeling his boyfriend's cock rubbing up against his inside your clenching and wet hole as you let out a sob and babbled incoherently about it being too much. Eventually Suguru made it all the way with Satoru as they waited for you to adjust to their lengths. After a few minutes they began thrusting you, forcing you to cum almost immediately and clamping around them hard. They hissed in satisfaction as they continued to thrust into you, absolutely abusing your poor cervix and g-spot as you moaned border line screamed in pain in pleasure. Your nails dug into Satoru's skin making him groan in pain before leaning towards the junction between your neck and shoulder and biting hard enough for you to bleed. You sobbed as your back arched and you tried to pry him off in response to the pain. Satoru pulled off and began licking your tears away with a taunting tone, “aww don't cry hun, you can take. Like the cute little cum dump you are. All that cun from me and Suguru filling you up. Making you round and perfect with tits full of milk~.”You whined at his words andSuguru kissing and lapping your injury gently from blood, the saccharine metallic flavor sweet in his mouth. “Satoru is right hun, you would look so lovely with our babies. What do you say…would you like to make our birthday boy's wish come true? His wish is our command after all.”

You though over his words before nodding, baby fever and being cock drunk overtaking your senses as you were fucked sensully on their cocks. One seemed to always be pressed against your cervix while the other glided through your walls. Your eyes lidded as you pleaded for them to cum in you causing their thrust to be much more harsher and quicker than before making you wail as they both lapped up your tears and praised you for being so good for them and their thrusts slowly became more sporadic. They were close as you came hard around them, your vision began to black out but the thick ropes of cum that finally filled you up shook you back awake with a moan and all three of you became exhausted.

The three of you panted heavily before your boyfriends removed their now flaccid cocks from you with a groan. You whimpered in response and watched as they admired you and praised you for being so good for them and allowing them to fill you up. Satoru plugs two into your hole as he stops his and Suguru's work from dripping out as you whine.

“Satoru I'm sensitive” you whimpered only for Suguru and Satoru to coax you with a coo. “I'm sorry hun, but we can't let you waste our cum. I really was serious about knocking you up” Satoru hushed, making you whine more before Suguru spoke up “Its okay baby, we got you. We'll clean up and lay down for a while until everything settles down. Yeah?” he assured. You nodded and Suguru stood up and kissed your temple before walking off. “How'd you like your birthday present?” you mumbled into Satoru's shoulder. He grinned “It was unexpected, but I'd definitely go again…hell I'll go right now. It's still my birthday, no?” You pouted and shook your head “to sore. Need to sleep…maybe later?” he nodded “later.” Suguru returned and cleaned off the mess you guys made before hoisting you up from Satoru's arms. Your legs wrapped around his waist lazily as you buried your face into him. Satoru stood up and walked with you two all the way to the bedroom where Satoru was sandwiched between, in cuddles and affirmations.

“Happy birthday ‘toru”

“Happy birthday Satoru”

“we love you!”

“I love you both too, thank you for everything”

And with that all three of you lulled off to sleep in each other's arms. Not to be awakened for at least the next 5 hours.. or until you give Satoru that other round you promised.
