He picked up a Motorola 68000 based machine at a local swap meet. A few boards, a backplane, and a power supply. The only information provided is the machines original purpose: gas station pump control.</p>
<p>The computer in question is an embedded system. It uses a VME backplane, and all the cards are of the 3u variaety. The 68k and associated support chips are on one card. Memory is on another. A third card contains four serial ports. The software lives across three different EPROM chips. Time for a bit of reverse engineering!</p>
<p><span id="more-914854"></span></p>
<p>[Dave] quickly dumped the ROMs and looked for strings. Since the 68k is a big endian machine, some byte swapping was required to get things human readable. Once byte swapped, huge tables of human readable strings revealed themselves, including an OS version. The computer runs <a href="https://en.wikipedia.org/wiki/PSOS_(real-time_operating_system)" target="_blank">pSOS</a>, an older 68k based real time operating system – exactly what one would expect a machine from the 80’s to run.</p>

Just played my first game of #PumpItUp and... damn, this is WAY more fun than DDR

New #pumpitup thread for 2026.

This game has so many charts, and some of them just sit there unnoticed, free for the taking. Case in point: What Happened D20, my 3rd-best score on any level 20 chart.

Not sure if I'm getting back up to speed fast, or slow, or about as I should expect.

Fui jogar #pumpitup hoje e acabei encontrando um amigo que não via há anos. Além disso percebi que há uma nova geração de pumpers se formando e eu to contente e orgulhoso. Não deixe a pump morrer :madotsuki:

Got new shoes and we're even more so back. Turns out switching to lighter shoes really is just like taking off training weights!

@jehansanspour de fait, elle a un rythme qui fait monter le cardio très très vite... #PumpItUp

I missed this post. If Pump It Up 2026 is being revealed at IAAPA we should be hearing something between November 17th and 21st.

Mais revenons à #PumpItUp.

Fin septembre se déroulait le premier tournoi européen, l'Europump Tournament. Le meilleur moment pour voir et apprendre des meilleurs.

Et j'y étais photographe 📷
Les photos sont sorties, et sont consultables pour les curieux : https://photos.matias49.eu/index/category/5

Des bornes Pump It Up, ou globalement des salles d'arcade, il y en a quelques unes en France. Annuaire Arcade et Zenius sont de bons annuaires.

https://zenius-i-vanisher.com/v5.2/arcades.php

Et non, l'arcade n'est pas mort en France ! 🕺

J'ai découvert une communauté ultra bienveillante, qui n'hésite pas à encourager la moindre amélioration et à se dépasser. Prête aussi à faire découvrir cet univers et tous ses jeux.

Aujourd'hui, je suis loin d'être expert, mais je ne suis plus débutant. La courbe de progression est à la fois immense et gratifiante.

#PumpItUp et #DDR ne sont qu'une partie de cette caverne d'Alibaba. Parce qu'il n'y a pas que les jambes qui peuvent danser. #DJMAX, #Beatmania se jouent uniquement avec les mains.

En Avril j'ai découvert #PumpItUp, une borne d'arcade de jeu de rythme (appelé aussi jeu musical).

Vous avez sûrement déjà vu la version Konami : Dance Dance Revolution (#DDR). C'est le même principe de danser, mais sur 5 touches.

J'ai toujours été épaté par ces vidéos de joueurs expérimentés, ces Perfect à la pelle et des mouvements qui paraissent fous.

J'apprécie ces jeux musicaux. Cette fois, j'ai décidé que j'allais essayer de m'entraîner et de pouvoir, peut-être, un jour faire comme eux.

Hit the arcade over the weekend to play #PumpItUp. Finally played enough to get the intermediate title.
