Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna January 1981, MOS Technology, Inc., Commodore's integrated circuit design subsidiary, yakatanga chirongwa chokugadzira mifananidzo uye audio chips nokuda kwechizvarwa chinotevera chevhidhiyo game console. Basa rokugadzira machipisi, ainzi MOS Technology VIC-II (Video Integrated Circuit for graphics) uye MOS Technology SID (Sound Interface Device for audio), rakapedzwa muna November 1981. Commodore akabva atanga chirongwa chemutambo weconsole waizoshandisa machipisi matsva anonzi Ultimax kana Commodore MAX Machine, yakagadzirwa naYash Terakura kubva kuCommodore Japan. Pakupedzisira chirongwa ichi chakabviswa pashure pokunge michina mishomanana yagadzirwa nokuda kwemusika weJapan. Panguva imwecheteyo, Robert "Bob" Russell (system programmer uye architect paVIC-20) naRobert "Bob" Yannes (injiniya weSID) vakatsoropodza chigadzirwa chazvino paCommodore, chaive kuenderera mberi kweCommodore PET mutsara wakanangana nevashandisi vebhizinesi. With rutsigiro Al Charpentier (injiniya pamusoro VIC-II) uye Charles Winterble (maneja MOS Technology), ivo zvinganaka kuti Commodore CEO Jack Tramiel wechokwadi yakaderera mutengo kutevera kuti VIC-20. Tramiel akarayira kuti muchina wacho unofanira kuva ne64 KB yeRandom-access memory (RAM). Kunyange zvazvo 64-Kbit dynamic random-access memory (DRAM) chips dzaidhura US$100 (yakaenzana ne $232.95 muna 2018) panguva iyoyo, aiziva kuti mitengo yeDRAM yakanga ichidonha, uye yaizodonha kusvika pamwero unogamuchirwa kugadzirwa kuzere kusati kwasvika. Chikwata chakakwanisa kukurumidza kugadzira komputa nekuti, kusiyana nemamwe makambani emakomputa epamba, Commodore yaive neayo semiconductor fekitori yekugadzira machipisi ekuyedza; nekuti fekitori yanga isiri kumhanya zvizere, mari yekuvandudza yaive chikamu chemari iripo yekambani. Machipisi akanga apedzwa munaNovember, panguva iyo Charpentier, Winterble, naTramiel vakanga vasarudza kupfuurira nekombiyuta itsva; iyo yekupedzisira yakaratidza nguva yekupedzisira yevhiki yekutanga yaJanuary, kuti iwirirane neConsumer Electronics Show (CES) ya1982. Chigadzirwa chacho chaiva zita rekodhi VIC-40 semutsivi weVIC-20 yakakurumbira. Iyo...  Mubvunzo: RAM rinomiririrei?
