Predt\u00fdm som im ve\u013emi neholdoval, ale od doby vyhl\u00e1senia s\u00fa\u0165a\u017ee na PMI-80<\/a> s\u00fa jednodosk\u00e1\u010de omnoho viac v mojom z\u00e1bere.<\/p>\n\n\n\n\n\n\n\n

S Martinom \u010cern\u00fdm sme si odvtedy poskladali Kim Uno<\/a> a on potom k tomu pridal svoj vlastn\u00fd projekt PMI-80 Uno (podrobnosti ur\u010dite vydaj\u00fa na samostan\u00fd \u010dl\u00e1nok).<\/p>\n\n\n\n

No ja som sa aktu\u00e1lne vrhol na SB8035.<\/p>\n\n\n\n

O tomto zauj\u00edmavom jednodosk\u00e1\u010di z Tesly som sa dozvedel z p\u00f4vodn\u00fdch str\u00e1nok Nostalcompu, kde v\u0161ak bola iba letm\u00e1 zmienka, \u017ee tak\u00e9 nie\u010do existovalo.
Za\u010dal som teda p\u00e1tra\u0165 a podarilo sa mi z\u00edska\u0165 nov\u00fa dosku na repliku tohto po\u010d\u00edta\u010da. T\u00e1 si samozrejme celkom dlho post\u00e1la v \u0161ufl\u00edku, ale nakoniec sa podarilo pozh\u00e1na\u0165 aj exotick\u00e9 obvody, dosku osadi\u0165 a o\u017eivi\u0165.<\/p>\n\n\n\n

Ako u\u017e n\u00e1zov napoved\u00e1 jedn\u00e1 sa o v\u00fdukov\u00fa stavebnicu s mikrokontrol\u00e9rom MHB8035, ale d\u00e1 sa osadi\u0165 aj 8048 \u010di 8748. V\u00fdhoda 8035 je, \u017ee nem\u00e1 vstavan\u00fa ROM a preto sa d\u00e1 jednoduch\u0161ie ovl\u00e1da\u0165 „zvonku“. Doska m\u00e1 okrem MCU osaden\u00e9 2kB EPROM 2716 s monitorom zaberaj\u00facim iba 1kB, 1kB RAM (2x 2114), volite\u013en\u00fd perif\u00e9rny obvod 8155 a 2 expand\u00e9ry portov 8243. \u010ealej je tam trochu logiky na dek\u00f3dovanie oblast\u00ed pam\u00e4te, tranzistory na budenie \u00f4smych sedemsegmentoviek a kl\u00e1vesnica z 24 resp. 32 telef\u00f3nnych tla\u010d\u00edtok plus jedno na reset.<\/p>\n\n\n\n

Ve\u013ekou v\u00fdhodou je mo\u017enos\u0165 nap\u00e1jania jedin\u00fdm zdrojom nap\u00e4tia 5V, tak\u017ee to prip\u00e1jam na be\u017en\u00fa power banku.<\/p>\n\n\n\n

Celkov\u00fd dojem z tohto jednodosk\u00e1\u010da je pr\u00edjemnej\u0161\u00ed ako z PMI-80, ktor\u00e9 samozrejme vzniklo v inej dobe a pri jeho v\u00fdvoji sa sledovalo hlavne pou\u017eitie dostupn\u00fdch hotov\u00fdch komponentov z kalkula\u010dky (kl\u00e1vesnica, displej) bez oh\u013eadu na zlo\u017eitos\u0165 nap\u00e1jania. Displejov\u00e9 segmenty SB8035 s\u00fa v\u00fdrazne lep\u0161ie \u010ditate\u013en\u00e9 a kl\u00e1vesnica m\u00e1 tak\u00fd „famili\u00e1rny chod“ ako PMD85-1 alebo PP01. \u010co v\u0161ak absentuje je pripojenie extern\u00e9ho pam\u00e4\u0165ov\u00e9ho zariadenia. V n\u00e1vode sa spom\u00edna mo\u017enos\u0165 pripoji\u0165 CMOS RAM z\u00e1lohovan\u00fa bat\u00e9riou. V z\u00e1kladnej v\u00fdbave v\u0161ak zahrnut\u00e1 nie je. Tak\u017ee „v\u00fdvoj“ na tomto syst\u00e9me je v zmysle vysk\u00fa\u0161aj si a zap\u00ed\u0161 na papier, alebo zabudni.<\/p>\n\n\n\n

Zatia\u013e som sa k nap\u00edsaniu zmyslupln\u00e9ho programu nedostal. Bude to chcie\u0165 opr\u00e1\u0161i\u0165 vedomosti o intel\u00e1ckych jedno\u010dipoch, ktor\u00e9 zapadli prachom od priemyslovky, kde sme mali nejak\u00e9 podobn\u00e9 kity len s modernej\u0161\u00edm 8051 a ur\u010dite neboli od Tesly.<\/p>\n\n\n\n

Dosku sa mi podarilo napasova\u0165 do drevenej krabi\u010dky od nejak\u00fdch fajnov\u00fdch bonb\u00f3nov, tak\u017ee ju na verejnosti prezentujem ako dreven\u00fd laptop z roku 1985 resp. jeho repliku. SB8035 tieto parametre sp\u013a\u0148a – m\u00e1 predsa zabudovan\u00fa kl\u00e1vesnicu aj displej a tie\u017e nev\u00eddan\u00fd v\u00fdpo\u010dtov\u00fd v\u00fdkon jedno\u010dipu na 4MHz. So „vstavanou“ bat\u00e9riou v podobe powerbanky neexistuje d\u00f4vod pre\u010do by sme tomu nemali veri\u0165 \ud83d\ude09<\/p>\n\n\n\n

Martin Luk\u00e1\u0161ek prehnal p\u00f4vodn\u00fa dokument\u00e1ciu OCR-kom, tak\u017ee si m\u00f4\u017eete stiahnu\u0165 u\u017e\u00edvate\u013esk\u00fa pr\u00edru\u010dku<\/a>.
