I-ZX Microdrive: ukugcinwa kwedatha yebhajethi, isitayela sama-1980s

Kubantu abaningi ababesebenzisa amakhompyutha asekhaya angu-8-bit ekuqaleni kwawo-1980, ukusebenzisa amakhasethi ukugcina izinhlelo kwakuyinkumbulo ehlala njalo.Abantu abacebe kakhulu kuphela abakwazi ukukhokhela amadrayivu ediski, ngakho-ke uma ungawuthandi umqondo wokulinda ikhodi ukuthi ilayishe unomphela, kusho ukuthi uphelelwe inhlanhla.Nokho, uma ungumnikazi weSinclair Spectrum, ngo-1983, usunenye inketho, iSinclair ZX Microdrive eyingqayizivele.
Lena ifomethi ethuthukiswe ngaphakathi ngabakwa-Sinclair Research.Empeleni inguqulo encane yenqola ye-loop tape engapheli.Ivele isesimweni sekhasethi le-Hi-Fi enamathrekhi angu-8 eminyakeni eyishumi edlule futhi ithembisa izikhathi zokulayisha ngokushesha.Imizuzwana kanye nomthamo omkhulu wesitoreji owedlula u-80 kB.Abanikazi beSinclair bangakwazi ukuhambisana nabafana abakhulu emhlabeni wamakhompiyutha asekhaya, futhi bangakwenza lokho ngaphandle kokuphula ibhange kakhulu.
Njengomhambi owayebuya ekamu labaduni ezweni, ngenxa yalolu bhubhane, uhulumeni waseBrithani wadinga ukuthi ngihlaliswe ngedwa amasonto amabili.Ngikwenze njengesivakashi sikaClaire.UClaire ungumngane wami futhi kwenzeka ukuthi ungumthombo wolwazi.I-Prolific 8-bit Sinclair hardware kanye nomqoqi wesofthiwe.Ngenkathi exoxa ngeMicrodrive, akathenganga nje izibonelo ezithile zamadrayivu nesoftware, kodwa futhi nohlelo lwesixhumi esibonakalayo kanye nekhithi yokuqala ye-Microdrive enebhokisi.Lokhu kwanginika ithuba lokuhlola nokuhlakaza uhlelo futhi nginikeze abafundi imininingwane ethakazelisayo ngale divayisi ewumngcele ongajwayelekile.
Thatha i-Microdrive.Kuyiyunithi ekala cishe u-80 mm x 90 mm x 50 mm futhi inesisindo esingaphansi kwamagremu angu-200.Ilandela izimpawu zesitayela zika-Rich Dickinson njengokhiye wangempela wenjoloba i-Spectrum.Ngaphambili kunesikhala esicishe sibe ngu-32 mm x 7 mm sokufaka ama-cartridges we-Microdrive tape, futhi ohlangothini ngalunye ngemuva kukhona isixhumi esinqenqemeni se-PCB esinezindlela eziyi-14 sokuxhuma ku-Spectrum kanye ne-daisy-chaining ngebhasi le-serial langokwezifiso Enye i-Microdrive. inikeza izintambo zeribhoni nezixhumi.Kungaxhunywa amadrayivu afinyelela kwayisishiyagalombili ngale ndlela.
Ngokwezintengo ekuqaleni kwawo-1980, i-Spectrum yayiwumshini owesabekayo, kodwa intengo yokuqaliswa kwayo yayiwukuthi yayikhokha kancane kakhulu isixhumi esibonakalayo esakhelwe ngaphakathi se-hardware ngaphandle kwamatheku ayo evidiyo nekhasethi.Ngemuva kwayo kunesixhumi esinqenqemeni, esidalula amabhasi ahlukahlukene e-Z80, sishiya noma yiziphi ezinye izindlela zokuhlangana ezixhunywe ngemojula yokwandisa.Umnikazi ojwayelekile we-Spectrum angase abe ne-adaptha ye-joystick ye-Kempston ngale ndlela, isibonelo esisobala kakhulu.I-Spectrum ayifakelwe neze isixhumi seMicrodrive, ngakho-ke iMicrodrive inesixhumi esibonakalayo sayo.I-Sinclair ZX Interface 1 iyiyunithi emise okweweji esebenzisana nesixhumi sonqenqema ku-Spectrum futhi isikulufe kuze kufike phansi kukhompuyutha.Ihlinzeka ngesixhumi esibonakalayo se-Microdrive, imbobo ye-serial ye-RS-232, isixhumi esibonakalayo se-LAN esilula sisebenzisa ujeke ongu-3.5 mm, kanye ne-Replica yesixhumi esinqenqemeni se-Sinclair esinezixhumanisi ezengeziwe ezifakiwe.Lesi sixhumanisi siqukethe i-ROM ezenza imephu ku-ROM yangaphakathi ye-Spectrum, njengoba sabonisa lapho i-prototype Spectrum ivela e-Cambridge Computing History Center, njengoba sazi sonke, ayikakaqedwa futhi eminye yemisebenzi yayo elindelekile ayikaqaliswa.
Kuyathakazelisa ukukhuluma nge-hardware, kodwa-ke, lena yi-Hackaday.Awufuni nje ukuyibona, ufuna ukubona ukuthi isebenza kanjani.Manje sekuyisikhathi sokuhlukanisa, sizoqala ngokuvula iyunithi ye-Microdrive ngokwayo.Njenge-Spectrum, ingaphezulu ledivayisi limbozwe ipuleti le-aluminium elimnyama elinelogo ye-Spectrum engokomfanekiso, okufanele ihlukaniswe ngokucophelela namandla asele okunamathela kwawo-1980s ukuze kuvezwe amakesi okukulufa amabili avikela ingxenye engaphezulu.NjengeSpectrum, kunzima ukwenza lokhu ngaphandle kokugoba i-aluminium, ngakho-ke amanye amakhono ayadingeka.
Phakamisa ingxenye engenhla bese ukhulula i-LED yomshayeli, idivayisi yomshini kanye nebhodi lesifunda livela emkhakheni wombono.Abafundi abanolwazi bazobona ngokushesha ukufana phakathi kwayo nekhasethi elikhulu lomsindo lamathrekhi angu-8.Nakuba lokhu kungekona okuphuma ohlelweni, kusebenza ngendlela efanayo kakhulu.Umshini ngokwawo ulula kakhulu.Ngakwesokudla kuneswishi encane ezwayo lapho itheyiphu isusa ilebula yokuvikela ukubhala, futhi ohlangothini lwesobunxele kukhona i-motor shaft ene-capstan roller.Ekupheleni kwebhizinisi le-tape kunekhanda le-tape, elibukeka lifana kakhulu nalokho ongase ukuthole kusiqophi sekhasethi, kodwa unomhlahlandlela omncane we-tape.
Kukhona ama-PCB amabili.Ngemuva kwekhanda letheyiphu kune-ULA yangokwezifiso enamaphini angu-24 (I-Uncommitted Logic Array, empeleni eyandulela i-CPLD ne-FPGA ngawo-1970) yokukhetha nokusebenzisa amadrayivu.Enye ixhunywe Engxenyeni engezansi yendlu ehlala izixhumi ezimbili zokusebenzelana kanye ne-electronic switch switch.
I-tape ingu-43 mm x 7 mm x 30 mm futhi iqukethe i-loop eqhubekayo yokugcoba i-self-lubricating tape enobude obungamamitha angu-5 nobude obungu-1.9 mm.Angimsoli u-Claire ngokungangivumeli ukuthi ngivule enye yamagobolondo akhe ayisidala, kodwa ngenhlanhla, i-Wikipedia isinikeze isithombe sekhathriji engaphezulu evaliwe.Ukufana ne-8-track tape kubonakala ngokushesha.I-capstan ingase ibe ohlangothini olulodwa, kodwa iluphu ye-tape efanayo ibuyiselwa phakathi nendawo ye-reel eyodwa.
Imanuwali ye-ZX microdrive ithi ngethemba ukuthi ikhasethi ngalinye lingabamba idatha engu-100 kB, kodwa iqiniso liwukuthi uma izandiso ezithile sezisetshenzisiwe, zingabamba cishe u-85 kB futhi zikhuphuke ziye ngaphezu kuka-90 kB.Kuyafaneleka ukusho ukuthi abawona abezindaba abathembekile kakhulu, futhi amakhasethi agcina eseluleme kwaze kwaba yilapho engasakwazi ukufundwa.Ngisho ne-Sinclair Manual incoma ukusekela amateyipu asetshenziswa kakhulu.
Ingxenye yokugcina yesistimu ezohlakazwa i-interface 1 ngokwayo.Ngokungafani nomkhiqizo we-Sinclair, awunazo izikulufo ezifihliwe ngaphansi kwezinyawo zenjoloba, ngakho-ke ngaphezu kokusebenza okucashile kokuhlukanisa phezulu kwendlu kusuka kusixhumi se-Spectrum edge, kulula futhi ukuhlakazeka.Ngaphakathi kukhona ama-chips amathathu, i-Texas Instruments ROM, ithuluzi elisebenza emhlabeni wonke i-ULA esikhundleni sephrojekthi ye-Ferranti esetshenziswa yi-Spectrum ngokwayo, kanye ne-74 logic encane.I-ULA ihlanganisa wonke amasekhethi ngaphandle kwamadivayisi ahlukene asetshenziselwa ukushayela i-RS-232, i-Microdrive, namabhasi e-serial enethiwekhi.I-Sinclair ULA idume ngokushisisa ngokweqile nokuzipheka, okuwuhlobo olusengozini kakhulu.Isixhumi esibonakalayo lapha asikwazi ukusetshenziswa kakhulu, ngoba asinayo irediyetha ye-ULA efakiwe, futhi alukho uphawu lokushisa phezu noma eduze kwegobolondo.
Umusho wokugcina wokuhlakazwa kufanele kube imanyuwali, okuyivolumu encane ebhalwe kahle enganikeza ukuqonda okujulile kwesistimu nokuthi ihlanganiswe kanjani kumhumushi we-BASIC.Amandla okuxhumana ayathandeka kakhulu ngoba awavamile ukusetshenziswa.Ithembele ku-Spectrum ngayinye kunethiwekhi ukuze ikhiphe umyalo wokuzabela yona inombolo lapho iqala, ngoba ayikho i-Flash noma inkumbulo efanayo ebhodini.Lokhu bekuhloselwe ukubeka imakethe yesikole njengesimbangi ku-Acorn's Econet, ngakho-ke akumangazi ukuthi i-BBC Micro iwine inkontileka yesikole esekelwa uhulumeni esikhundleni somshini we-Sinclair.
Kusukela ngo-2020, bheka emuva kulobu buchwepheshe bekhompuyutha obulibele bese ubheka umhlaba lapho indawo yokugcina engu-100 kB ilayishwa cishe imizuzwana engu-8 esikhundleni semizuzu embalwa yokulayisha itheyiphu.Okudidayo ukuthi i-Interface 1 ayifaki isikhombimsebenzisi sephrinta ehambisanayo, ngoba uma ubheka uhlelo oluphelele lwe-Spectrum, akunzima ukubona ukuthi sekuyikhompyutha eyanele yokukhiqiza yasehhovisi lasekhaya namuhla, kuhlanganise nenani layo.I-Sinclair iyawathengisa awabo amaphrinta ashisayo, kodwa ngisho nabathandi be-Sinclair abanenkanyezi kakhulu abakwazi ukubiza iphrinta ye-ZX ngephrinta entsha.
Iqiniso liwukuthi, njengabo bonke abakwaSinclairs, kwaba isisulu sokwehliswa kwezindleko okudumile kukaSir Clive kanye nekhono elikhaliphile lokudala ubuhlakani obungenakwenzeka ezingxenyeni ezingalindelekile.I-Microdrive yathuthukiswa ngokuphelele endlini nguSinclair, kodwa mhlawumbe yayincane kakhulu, ingathembeki kakhulu, futhi sekwephuze kakhulu.I-Apple Macintosh yokuqala efakwe i-floppy drive yaphuma ekuqaleni kuka-1984 njengomkhiqizo wamanje we-ZX Microdrive.Nakuba lawa makhasethi amancane angena emshinini ka-Sinclair we-16-bit QL ongasebenzi kahle, kuvele ukuthi kwaba ukwehluleka kwezentengiso.Lapho sebethenge izimpahla zikaSinclair, i-Amstrad izokwethula i-Spectrum nge-floppy disk engu-3-intshi, kodwa ngaleso sikhathi ama-microcomputer e-Sinclair ayethengiswa kuphela njengama-consoles omdlalo.Lokhu ukudilizwa okuthakazelisayo, kodwa mhlawumbe kungcono ukushiya nezinkumbulo ezijabulisayo zango-1984.
Ngimbonga kakhulu uClaire ngokusebenzisa ihadiwe lapha.Uma kwenzeka uyazibuza, isithombe esingenhla sibonisa izinhlobonhlobo zezingxenye ezahlukene, okuhlanganisa izingxenye ezisebenzayo nezingasebenzi, ikakhulukazi iyunithi ye-Microdrive ehlakazwe ngokuphelele iyiyunithi ehlulekile.Asifuni ukulimaza ihadiwe yekhompuyutha ebuyela emuva ngokungadingekile ku-Hackaday.
Ngisebenzise i-Sinclair QL iminyaka engaphezu kweyisikhombisa, futhi kufanele ngisho ukuthi ama-microdrive abo awekho intekenteke njengoba abantu besho.Ngivame ukuzisebenzisela umsebenzi wesikole wesikole, njll., futhi angilokothi ngiphuthelwe noma yimaphi amadokhumenti.Kodwa kukhona ngempela ezinye izisetshenziswa "zesimanje" ezithembeke kakhulu kunalezo zakuqala.
Mayelana ne-Interface I, kuyaxaka kakhulu ekwakhiweni kukagesi.Imbobo ye-serial iyi-adaptha yezinga, futhi iphrothokholi ye-RS-232 isetshenziswa isofthiwe.Lokhu kubangela izinkinga lapho uthola idatha, ngoba umshini unesikhathi kuphela sokuthi i-stop bit yenze noma yini okudingeka iyenze ngedatha.
Ngaphezu kwalokho, ukufunda kusuka ku-tape kuyathakazelisa: unechweba le-IO, kodwa uma ufunda kulo, isikhombimsebenzisi ngizomisa iphrosesa kuze kube yilapho i-byte egcwele ifundwa ku-tape (okusho ukuthi uma ukhohlwa Vula i-tape motor. futhi ikhompuyutha izolenga).Lokhu kuvumela ukuvumelanisa okulula kweprosesa kanye ne-tape, okudingekayo ngenxa yokufinyelela kwe-memory block yesibili ye-16K (eyokuqala ine-ROM, eyesithathu neyesine inememori eyengeziwe yamamodeli angu-48K), futhi ngenxa yebhafa ye-microdrive Iyenzeka. ukuba kuleyo ndawo, ngakho-ke akunakwenzeka ukusebenzisa izihibe ezinesikhathi kuphela.Uma i-Sinclair isebenzisa indlela yokufinyelela efana naleyo esetshenziswe ku-Inves Spectrum (evumela kokubili ukujikeleza kwevidiyo kanye neprosesa ukuthi ifinyelele i-RAM yevidiyo ngaphandle kokujeziswa, njenge-[ku-Apple, khona-ke isekethe yesixhumi esibonakalayo ibingaba lula Kakhulu.
I-Spectrum inesikhathi esiningi ngangokunokwenzeka sokucubungula amabhayithi atholiwe, inqobo nje uma idivayisi ngakolunye uhlangothi isebenzisa ngendlela efanele ukulawulwa kokugeleza kwehadiwe (kokunye (konke?) ama-motherboard "SuperIO" chips *hhayi* isimo. Ngimoshe izinsuku ezimbalwa ukulungisa iphutha ngaphambi kokuqaphela lokhu nokushintshela ku-adaptha ye-serial ye-USB endala, ngamangala ukuthi i-Just Worked isebenze okokuqala)
Mayelana ne-RS232.Ngithole ukulungiswa kwamaphutha angu-115k kanye no-57k othembekile we-bit bumping ngaphandle kwephrothokholi yokulungisa iphutha.Imfihlo iwukuqhubeka nokwamukela kufika kumabhayithi angu-16 ngemva kokulahla i-CTS.Ikhodi ye-ROM yasekuqaleni ayizange ikwenze lokhu, futhi ayikwazi ukuxhumana ne-UART “yesimanje”.
I-Wikipedia ithi 120 kbit/sec.Mayelana nephrothokholi ethile, angazi, kodwa ngiyazi ukuthi isebenzisa inhloko ye-stereo tape, futhi i-bit storage “ayiqondile”.Angazi ukuthi ngingakuchaza kanjani ngesiNgisi… izingcezu zethrekhi eyodwa ziqala phakathi kwezingcezu kwenye ithrekhi.
Kodwa ukusesha okusheshayo ngithole leli khasi, lapho umsebenzisi exhuma i-oscilloscope kusignali yedatha, futhi kubonakala sengathi i-modulation ye-FM.Kodwa iyi-QL futhi ayihambisani neSpectrum.
Yebo, kodwa sicela ukhumbule ukuthi isixhumanisi sikhuluma ngama-microdrive e-Sinclair QL: nakuba afana ngokomzimba, asebenzisa amafomethi angahambelani, ngakho-ke i-QL ayikwazi ukufunda amatheyipu efomethi ye-Spectrum, futhi ngokuphambene nalokho.
Kuqondaniswe kancane.Amabhayithi anqanyuliwe phakathi kwethrekhi 1 kanye nethrekhi 2. Iwumbhalo wekhodi wesigaba esiphindwe kabili.I-fm evame ukutholakala kumakhadi esikweletu.I-interface ihlanganisa kabusha amabhayithi ku-hardware, futhi ikhompuyutha ifunda amabhayithi kuphela.Izinga ledatha langempela ngu-80kbps ithrekhi ngayinye noma 160kbps kukho kokubili.Ukusebenza kufana namadiski e-floppy angaleso sikhathi.
Angazi, kodwa kwakukhona izihloko ezimbalwa mayelana nokuqoshwa okugcwele ngaleso sikhathi.Ukuze usebenzise isiqophi sekhasethi esikhona, amathoni omsindo ayadingeka.Kodwa uma ulungisa inhloko yetheyiphu yokufinyelela okuqondile, ungakwazi ukuzondla ngokuqondile ngamandla e-DC futhi uxhume ngokuqondile i-Schmitt trigger ukuze udlale.Ngakho-ke ivele iphakele isignali ye-serial yekhanda le-tape.Ungathola izivinini ezisheshayo ngaphandle kokukhathazeka ngezinga lokudlala.
Isetshenziswa nakanjani emhlabeni "we-mainframe".Ngihlale ngicabanga ukuthi isetshenziswa kwezinye izinhlelo zekhompiyutha ezincane, njengokuthi “ama-floppy disks”, kodwa angazi.
Ngine-QL enama-micro-drive angu-2, okuyiqiniso, okungenani i-QL ithembeke kakhulu kunalokho okushiwo abantu.Ngine-ZX Spectrum, kodwa awekho ama-microdrive (yize ngiwafuna).Into yakamuva engiyitholile wukwenza ukuthuthukiswa okuthile.Ngisebenzisa i-QL njengomhleli wombhalo futhi ngidlulisela amafayela ku-Spectrum ehlanganisa amafayela nge-serial (Ngibhala umshayeli wokuphrinta wohlelo lwe-ZX Spectrum PCB Designer, oluzothuthukisa futhi Ifake amaphikseli ekulungisweni kwe-216ppi ukuze ithrekhi ingagcini. abonakale ejahile).
Ngiyayithanda i-QL yami nesofthiwe yayo ehlanganisiwe, kodwa kufanele ngizonde i-microdrive yayo.Ngivame ukuthola amaphutha "BAD NOMA CHANGED MEDIUM" ngemva kokuphuma emsebenzini.Kuyakhungathekisa futhi akuthembekile.
Ngabhala iphepha lami le-BSc lesayensi yekhompyutha ku-128Kb QL yami.IQuill ingagcina cishe amakhasi ama-4 kuphela.Angikaze ngilokothe ​​ukuchichima inqama ngoba izoqala ukunyakazisa i-micro drive futhi iphutha livele maduze.
Bengikhathazeke kakhulu ngokuthembeka kweMicrodrive kangangokuthi angikwazi ukwenza isipele sonke isikhathi sokuhlela kumateyipu amabili e-Microdrive.Nokho, ngemva kokubhala usuku lonke, ngagcina ngephutha isahluko sami esisha ngaphansi kwegama lesahluko esidala, ngaleyo ndlela ngibhala phezu komsebenzi wami ngayizolo.
“Ngicabanga ukuthi kulungile, okungenani nginesipele!”;Ngemva kokushintsha itheyiphu, ngakhumbula ukuthi umsebenzi wanamuhla kufanele ulondolozwe kukhophi yasenqolobaneni futhi ubhale phezu komsebenzi wosuku lwangaphambilini ngesikhathi!
Ngisenayo i-QL yami, cishe unyaka odlule, empeleni ngasebenzisa ngempumelelo i-mini drive cartridge eneminyaka engama-30-35 ukuze ngiyilondoloze futhi ngiyilayishe.:-)
Ngisebenzise i-floppy drive ye-ibm pc, iyi-adaptha engemuva kwe-spectrum, ishesha kakhulu futhi imnandi.:)(qhathanisa nekhasethi imini nobusuku)
Lokhu kungibuyisela emuva.Ngaleso sikhathi ngagebenga yonke into.Kungithathe isonto ukufaka i-Elite ku-Microdrive futhi ngivumele i-LensLok njalo ibe indima AA.Isikhathi sokulayisha se-Elite amasekhondi angu-9.Uchithe ngaphezu komzuzu ku-Amiga!Ngokuyisisekelo iyindawo yokulahla inkumbulo.Ngisebenzise isimiso sokuphazamiseka ukuze ngigade i-int 31(?) yomlilo we-joystick yase-Kempston.I-LensLok isebenzisa iziphazamiso ekufakweni kwekhibhodi, ngakho-ke ngidinga nje ukuminya kukhodi ukuze ngiyenze ingasebenzi ngokuzenzakalelayo.I-Elite ishiye kuphela cishe amabhayithi angu-200 engasetshenziswa.Ngenkathi ngiyigcina ngokuthi *”m”,1, imephu yesithunzi yesixhumi esibonakalayo 1 igwinye ukuphazamiseka kwami!Hewu.Eminyakeni engu-36 edlule.
Ngikhohlise kancane… nginediski yefloppy ye-Discovery Opus 3.5-intshi ku-Speccy yami.Ngithole ukuthi ngenxa yengozi ejabulisayo ngosuku lapho i-Elite iphahlazeka ngenkathi ilayisha, ngiyakwazi ukulondoloza i-Elite kudiski ye-floppy… futhi iyinguqulo engu-128, akukho lock lens!umphumela!
Kuyathakazelisa ukuthi cishe eminyakeni engu-40 kamuva, i-floppy disk ifile futhi i-tape isekhona :) PS: Ngisebenzisa umtapo wezincwadi, ngamunye unamadrayivu angu-18, idrayivu ngayinye inganikeza isivinini esingu-350 MB / s;)
Ngifuna ukwazi ukuthi uma uqaqa i-adaptha yekhasethi, ungasebenzisa ikhanda kazibuthe ukuze ulayishe idatha kukhompyutha nge-microdrive?
Amakhanda afana kakhulu, uma kungenjalo (kodwa "ikhanda le-eraser" kufanele lihlanganiswe ku-schematic), kodwa i-tape ku-microdrive incane, ngakho-ke kufanele wakhe umhlahlandlela omusha we-tape.
"Abantu abacebe kakhulu kuphela abakwazi ukukhokhela ama-disk drive."Mhlawumbe e-UK, kodwa cishe wonke umuntu e-US unazo.
Ngikhumbula izindleko ze-PlusD + disk drive + i-adaptha yamandla, ngo-1990, yayingaba ngu-33.900 pesetas (cishe ama-euro angu-203).Nge-inflation, manje isingama-Euro angama-433 (512 USD).Lokhu kucishe kufane nezindleko zekhompyutha ephelele.
Ngiyakhumbula ukuthi ngo-1984, intengo ye-C64 yayiyi-US $ 200, kanti intengo ye-1541 yayiyi-US $ 230 (empeleni iphakeme kunekhompyutha, kodwa uma ucabangela ukuthi ine-6502 yayo, lokhu akumangalisi).Lezi ezimbili kanye ne-TV eshibhile kusengaphansi kwekota yenani le-Apple II.Ibhokisi lama-floppy disks angu-10 lithengiswa ngo-$15, kodwa intengo iye yehla ngokuhamba kweminyaka.
Ngaphambi kokuthi ngithathe umhlalaphansi, ngasebenzisa inkampani enhle kakhulu yokuklama imishini kanye nekhiqizayo enyakatho yeCambridge (UK), eyakha yonke imishini esetshenziselwa ukwakha amagobolondo e-Microdrives.
Ngicabanga ukuthi ekuqaleni kwawo-1980, ukuntuleka kwechweba elihambisanayo elihambisana ne-centronics kwakungeyona into enkulu, futhi amaphrinta we-serial ayesavamile.Ngaphandle kwalokho, uMalume uClive ufuna ukukudayisela i-ZX FireHazard...iphrinta yomthombo.I-hum engapheli kanye nephunga le-ozone njengoba ihamba phansi ephepheni elinesiliva.
Ama-Micro drives, inhlanhla yami yayimbi kakhulu, ngangigcwele isifiso ngawo lapho ephuma, kodwa kwaze kwaba ngemva kweminyaka embalwa lapho ngaqala khona ukucosha i-hardware eshibhile ezimpahleni eziseke zasetshenziswa, futhi angizange thola noma iyiphi ihadiwe.Ngigcine senginamachweba angu-2 1, ama-micro-drive angu-6, amakalishi asetshenziswa ngokungahleliwe, nebhokisi lamakalishi angu-30 amasha wesikwele amathathu, uma ngingakwazi ukuwenza kunoma iyiphi inhlanganisela engu-2×6 ngicasuka kakhulu uma ngisebenza indawo eyodwa.Ikakhulukazi, azibonakali zifomethiwe.Angikaze ngicabange ngakho, noma ngabe ngithole usizo kumaqembu ezindaba ngenkathi ngixhumeke ku-inthanethi ngasekuqaleni kwawo-90s.Kodwa-ke, njengoba senginamakhompyutha "angempela", ngithole ukuthi izimbobo ze-serial zisebenze, ngakho ngigcine izinto kuzo ngekhebula lemodemu elingenalutho futhi ngasebenzisa amatheminali ayisimungulu.
Ingabe ukhona obhale uhlelo "lokwelula ngaphambilini" amateyipu ngokuwasebenzisa ku-loop ngaphambi kokuzama ukuwafometha?
Anginayo i-micro drive, kodwa ngikhumbula ngiyifunda ku-ZX Magazine (eSpain).Lapho ngiyifunda, yangimangaza!:-D
Kubonakala ngikhumbula ukuthi iphrinta i-electrostatic, hhayi eshisayo… Kungenzeka ukuthi angilungile.Umuntu engisebenze ekuthuthukiseni isofthiwe eshumekiwe ngasekupheleni kweminyaka yama-80s uxhume eyodwa yamadrayivu etheyiphu ku-Speccy futhi waxhuma umhleli we-EPROM embotsheni engemuva.Ukusho ukuthi lokhu kuwukusetshenziswa kwe-bastard kungaba ukunganaki.
Nakanye.Iphepha limbozwe ungqimba oluncane lwensimbi, futhi iphrinta ihudulela uthayela lwensimbi ngaphesheya.Ukushaya kwe-voltage ephezulu kukhiqizwa ukuze kucinywe insimbi noma kuphi lapho kudingeka khona amaphikseli amnyama.
Lapho usemusha, i-ZX interface 1 ene-RS-232 ikwenza uzizwe “njengenkosi yomhlaba”.
Eqinisweni, ama-Microdrives adlule ngokuphelele isabelomali sami (esincane).Ngaphambi kokuthi ngihlangane nalo mfana othengisa imidlalo yokudlwengulwa LOL, akekho engangimazi.Uma ngibheka emuva, kufanele ngithenge i-Interface 1 neminye imidlalo ye-ROM.Njengevelakancane njengamazinyo esikhukhukazi.
