DISC-2/1

Budu se zde výhradně věnovat technickým prostředkům a to proto, že již existují stránky které se věnují tomuto počítači např. ZDE (jejich zrcadlo) a nebo ZDE.

Originální a další dokumentace je k dispozici například ZDE a zrcadlo, technický popis nemusí vždy odpovídat schématům, co jsem spáchal, protože až na vzácné výjimky šlo o získaní schémat metodou zpětného inženýrství.

Schéma kompletně získáno metodou zpětného inženýrství.
