Un billet pour noter quelques caractéristiques de divers périphériques et matériels que j'utilise actuellement… comme certaines configurations sont assez anciennes j'ai bien peur que les pages recélant les informations les plus complètes ne finissent par disparaître tôt ou tard.

Et cette page devrait m'éviter de refaire de longues recherches quand j'en aurai, à nouveau, besoin.

Si jamais ça peut servir à d'autres, sans que ceux-ci ne doivent se farcir les pages sans intérêt, mais pas désintéressées , des guides d'achats en marque blanche…
