Guida al riconoscimento di hardware storico

A cura di Gabriele Zaverio, Museo dell'Informatica Funzionante, Palazzolo Acreide (SR) http://museo.freaknet.org

Questo documento elenca i criteri che permettono di riconoscere quale hardware (computer, monitor, periferica, dispositivo elettronico, scheda, rack o altro ancora) puo' essere di interesse storico rispetto ad altro hardware piu' recente o di nessun interesse.

Criteri di base

Per un primo riconoscimento possiamo classificare i seguenti metodi di indagine:

Marche e case produttrici
Forma
Dimensione
Materiali utilizzati
Colori

Marche e case produttrici

Alcune case produttrici oggi non esistono piu'; e' quindi facile identificare hardware di interesse storico in base alle seguenti marche:

Acorn Computers Adam Colecovision Altos Amstrad Apple Computers Apricot AST Research Atari Bondwell British Telecom Burroughs Corporation Cobalt Commodore Compaq Data General Dell Digital DEC Dragon Data Ltd EDSAC Enigma (Gemini - Galaxy) Epson Ferranti GRiD Grundy NewBrain Hewlett Packard IBM ICL ICT IMSAI Intel Intermedia Graphic Systems Intersil Intertec ITT Kaypro Kokusai Electric | Mattel Electronics MITS - Altair Mitsubishi Motorola National Semiconductor NEC Corporation NeXT Computers Ohio Scientific Olivetti Oric Osborne Panasonic Philips Radio Shack - Tandy Rockwell International Sanyo Seiko Sharp Siemens Silicon Graphics - SGI Sinclair Sirius Systems Technology Sony Sord / CGL Sun Microsystems Symbolics Tatung Einstein TeleVideo Texas Instruments Toshiba Triumph-Adler Alphatronic - Matmos PC Wang Xerox Zenith Data Systems Zilog

Forse e' il caso di sfoltire ed eliminare alcuni di questi loghi/marche? Sono troppi?

Forma

I computer di una volta avevano forme differenti rispetto a quelli odierni. Di seguito, ecco alcuni esempi, in ordine piu o meno cronologico.

Rack

Scheda

Misto legno/metallo

Alcuni computer di una volta sfoggiavano contenitori con eleganti combinazioni di legno e metallo.

Unita centrale e tastiera insieme

Unita centrale, schermo e tastiera insieme

Forme strane e particolari

Alcuni sembrano calcolatrici, ma sono computer veri e propri:

Colori inusuali

I sistemi di un tempo spesso sfoggiavano colori sgargianti: azzurro, blu, rosa, rosso, giallo, con diverse combinazioni.

Dimensione

Le dimensioni dei computer storici ed in generale dell'hardware erano piu' generose nei sistemi di alcuni anni fa.

Materiali utilizzati

Metallo verniciato a polvere, resina, abs? Plastiche ingiallite? Rack industriali? Involucri misti legno/metallo?

Analisi del pezzo

Quando si sospetta che un pezzo abbia interesse storico o sia di una certa eta', possiamo esaminarlo in base ai seguenti criteri

Schede interne: come sono fatte?
Datazione su etichette esterne: ci sono delle date di collaudo, di scadenza garanzia o altro?
Datazione sui chip delle schede interne

Schede interne

Le schede di interesse storico solitamente sono riconoscibili dal loro colore, differente dalle schede dei computer odierni, e dalle forme particolari.

Datazione su etichette esterne

Spesso le date si trovano su etichette apposte sul computer o sulle schede.

Datazione sui chip delle schede interne

I circuiti integrati (CHIP) portano su di essi un codice che identifica la data di produzione, e quindi verosimilmente e' possibile datare una scheda in base alle date dei chip montati su di essa. Il codice utilizzato e' a 4 cifre, che identifica l'anno di produzione e la settimana.

Marche non storiche

==== Colori inusuali ====

I sistemi di un tempo spesso sfoggiavano colori sgargianti: azzurro, blu, rosa, rosso, giallo, con diverse combinazioni.

+=== Schede interne ===

Le schede di interesse storico solitamente sono riconoscibili dal loro colore, differente dalle schede dei computer odierni, e dalle forme particolari.

+I circuiti integrati (CHIP) portano su di essi un codice che identifica la data di produzione, e quindi verosimilmente e' possibile datare una scheda in base alle date dei chip montati su di essa. Il codice utilizzato e' a 4 cifre, che identifica l'anno di produzione e la settimana.
