About: +D

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The +D (or Plus D) was a floppy disk and printer interface for the Sinclair ZX Spectrum home computer, developed as a successor to Miles Gordon Technology's earlier product, the DISCiPLE. It was designed to be smaller, cheaper, simpler and thus more reliable. It discarded a number of the less important features of the earlier product — the network and joystick ports, the inhibit button and the pass-through connector — and replaced its ancestor's plastic wedge-shaped design which fit under the Spectrum with a simple flat metal slab which protruded from the rear of the computer.

  • The +D (or Plus D) was a floppy disk and printer interface for the Sinclair ZX Spectrum home computer, developed as a successor to Miles Gordon Technology's earlier product, the DISCiPLE. It was designed to be smaller, cheaper, simpler and thus more reliable. It discarded a number of the less important features of the earlier product — the network and joystick ports, the inhibit button and the pass-through connector — and replaced its ancestor's plastic wedge-shaped design which fit under the Spectrum with a simple flat metal slab which protruded from the rear of the computer. It provided only floppy disk and Centronics parallel interfaces, plus a non-maskable interrupt button. The +D's casing was simple folded steel, which was not only stronger than before but acted as a heatsink, improving reliability. Apart from the missing ports, though, it was software-compatible with the larger device. The +D's DOS was named G+DOS, and was compatible with the DISCiPLE's DOS, GDOS. SAM DOS for MGT's SAM Coupé was backwards-compatible with GDOS and G+DOS. "The Complete +D Disassembly" by Rudy Biesma documents the "G+DOS system 2a" version. An enhanced version called Beta DOS fixed bugs and added features. In later years a complete new system called UNI-DOS was developed by SD Software for the DISCiPLE and +D interfaces. The popularity of the DISCiPLE led to the formation of a user group and magazine, INDUG, which later became Format Publications. Usergroups like INDUG/Format in the UK or DISCiPLE-Nieuwsbrief in the Netherlands produced enhancements such as extended printer support. The +D design was later licensed by Datel and it continued on sale for some years after MGT's demise. Its design and chips have been released into the public domain and it still remains available commercially or even as a DIY project. (en)
  • El Plus D o +D fue una interfaz de disquete e impresora de puerto paralelo para el ordenador doméstico Sinclair ZX Spectrum 16, 48, 128 y +2 (el de carcasa gris) si bien también se distribuyó un modelo compatible con el +3/+2A a través de un patch.​​ Se desarrolló como sucesor del DISCiPLE, primer producto de Miles Gordon Technology, con la idea de ser más barato, pequeño, simple, calentarse menos y ser así más fiable.

  • La +D (anche Plus D) è un'interfaccia sviluppata per gli home computer Sinclair ZX Spectrum che permetteva la connessione di unità dischi e stampanti. Fu sviluppata da Miles Gordon Technology (MGT) come erede della DISCiPLE, rispetto alla quale era più piccola, più economica, più semplice e dalla linea più semplice. Per contenere il costo e le dimensioni, MGT aveva eliminato dalla scheda della DISCiPLE alcune funzionalità quali le porte joystick, il supporto alle reti, il pulsante per disattivare l'interfaccia e la replica della porta di espansione ed aveva rivisto il contenitore scartando quello ingombrante in plastica che restava sotto al computer, sostituendolo con uno metallico più semplice e piatto che sporgeva da dietro lo ZX Spectrum. La +D offriva solo, oltre al supporto alle unità dischi, una porta Centronics ed il "pulsante magico" per attivare l'interrupt non mascherabile che riversava su disco il contenuto della memoria del computer. Il contenitore era di acciaio che non solo era più resistente di quello della DISCiPLE ma fungeva anche da dissipatore di calore, cosa che aiutava ad aumentare la durata del dispositivo. A parte queste differenze hardware, l'interfaccia era compatibile a livello di software con la precedente. Il sistema operativo era denominato G+DOS: deriva dal GDOS della DISCiPLE, con cui è compatibile. Il SAMDOS, il sistema operativo del SAM Coupé, è compatibile sia con il G+DOS che con il GDOS. Negli anni seguenti S.D. Software sviluppò un nuovo sistema operativo chiamato UNI-DOS, compatibile sia con la DISCiPLE che con la +D. Nell'ottobre del 1993 Ruby Biesma pubblicò il libro "The Complete DISCiPLE Disassembly" che documentava il GDOS versione 3d. La licenza della +D fu in seguito acquistata anche da , che ha continuato a vendere la scheda per diversi anni dopo il fallimento di MGT. (it)
