isixhumi se-hd15

Ngemva kokusebenzisa i-laptop iminyaka engaphezu kweyishumi, ngabuyela kwikhompyutha yedeskithophu ezinyangeni ezimbalwa ezedlule. I-PC encane yenkampani yangaphambili kanye nesikrini esikhulu esibanzi zibekwe esitendini, kanye negundane elifanele kanye ne-IBM Model M ethembekile engiyikhonze amashumi eminyaka. Ngokungazelelwe, i-ergonomics yendawo yami yokusebenza yaba ngcono ngoba angisadingi ukugoba kancane ukuze ngibone isikrini.
Amakhompyutha edeskithophu angaphambilini avela esikhathini sangaphambilini. Ngicabanga ukuthi inanoma yibaphi abancintisana ne-AMD abancintisana ne-Pentium 4, futhi uma ngikhumbula kahle, inkumbulo yayo engu-512 MB ibhekwa njengebaluleke kakhulu. Ngemuva, inesethi yama-sockets ahluke ngokuphelele kusokhethi yami entsha, isethi yama-serial ports, i-SCSI port, kanye ne-parallel printer port. Ngaphakathi kwe-chassis, ama-drive ayo ahlukahlukene akhonzwa yisethi yama-ribbon cables. Ize ibe ne-floppy drive. Ngokuphambene nalokho, izintambo zemikhiqizo yayo elandelayo zilula kakhulu, futhi usayizi wesixhumi uncane kakhulu. Ama-plug e-USB amaningana kanye nekhebula lenethiwekhi, kanye ne-SATA yama-disk drive ayo. Isikhathi esikhulu sokuxhumana okuningi sesiphelile, futhi iningi lethu lingakhululeka.
Inkinga ngamakhebula amaningi ukuthi ayevame ukubiza kakhulu ngaleso sikhathi, ngakho-ke ngisacabanga ukuthi anenani elithile. Ngakho-ke noma idrayivu yami yokugcina ye-SCSI noma i-monitor ye-VGA isisuse le khoyili ebulalayo, ngisalenga kukhebula, uyazi, uma kwenzeka. Kukhona ibhokisi eliqhumayo elifihliwe eshalofini ndawana thize, noma uma usesikhundleni sami sokukhiqiza eMilton Keynes, amabhokisi amaningi aqhumayo. Ngaphambi kokuba ngiqede ukuhlanza, ake sibheke ngokucophelela lezi zinto zobuciko, sicabange ukuthi ngeke ucasuke ngokuthatha i-cutter uye kwezinye izintambo eziphelele. Skena inqwaba, futhi iningi lihlukaniswe ngamaqembu amane amakhulu. I-SCSI ehambisanayo, i-VGA, iphrinta ehambisanayo, futhi ngoba lena ikhebula le-SCART elinokubukwayo kweziteshi eziningi elibhalwe eYurophu.
Njengoba ubungalindela kusukela ku-interface ehambisanayo, ikhebula le-SCSI lithatha isimo sezintambo eziningi, kodwa uma ubhekisisa ngaphakathi kwepulaki, isimanga ukuthi akukho umbhangqwana ovikelayo noma osontekile phakathi kwezintambo. Ikhebula lephrinta ehambisanayo linesakhiwo esifanayo kakhulu: liyi-port engu-8-bit kuphela ku-host. Ngakolunye uhlangothi, izintambo ze-VGA neze-SCART ziqukethe uchungechunge lwama-coaxial shield coaxial conductors wezimpawu zevidiyo kanye nezinye izintambo zodwa zezibonakaliso zokulawula.
Kwakuyilapho ngicabanga ngendlela yokusebenzisa kabusha izintambo ezinjalo lapho ngaqaphela khona ukuthi sithuthuke kangakanani kusukela esikhathini sezixhumi eziningi zekhebula. I-USB manje ihlanganisa amadivayisi amaningi edeskithophu ayekade ekhonzwa yizixhumi ze-SCSI ezihambisanayo, ezihambisanayo, kanye nezixhumi ezilandelanayo, futhi cishe konke ukuxhumana okubonakalayo okulalelwayo kushintshela ngokushesha ku-HDMI. Lezi zixhumi ezilandelanayo ezisheshayo zinikeza amazinga aphezulu edatha ngezintambo zethusi ezimbalwa.
Kubonakala sengathi kunezintambo eziningi engizibonile yonke indawo, futhi empeleni azisenamsebenzi. Ngokungafani nezinye izinguquko zobuchwepheshe, njengokusuka kuma-vacuum tube kuya kuma-transistors, ukusebenza kwazo akukanciphi ngobuchwepheshe obusha, ngakho-ke impilo yazo yesevisi ayidlulanga impilo yazo yesevisi. Ngokuphambene nalokho, lapho ubuchwepheshe bazo bufika esicongweni, ngokushesha ziba yi-e-waste, lapho singathola khona umthombo wenani lazo lokuchazwa. Uma unezintambo eziningi ze-SCSI ndawana thile, ingabe uyazibamba ngoba ucabanga ukuthi uzozidinga futhi ngolunye usuku?
Ukushisa izintambo ukuze kutholakale ithusi, 2018, e-Accra, eGhana. Muntaka Chasant [CC BY-SA 4.0]. Ngakho-ke kufanele senzeni? Zingasetshenziswa yini kwezinye izinjongo? Kunoma ikuphi, ubani osebenzisa i-wire bundle yezindlela ezingu-40 noma inqwaba yezintambo ze-coaxial ezingezinhle kulezi zinsuku? Ngingathanda ukuzwa umbono wakho kumazwana.
Ngesikhathi esifanayo, nginezintambo eziningi okufanele ngibhekane nazo, futhi lena inkinga. Ithusi eliqukethwe kulo liyigugu, kodwa ezimweni eziningi, izinto zalo zokuvikela ziyi-PVC. Ukuphinda kusetshenziswe kungaba yinkinga. Uma ukusebenza kahle kokusha kuphansi, kuzokhipha amakhemikhali anobuthi. Eminyakeni edlule, kube nochungechunge lwezigameko ezihilela ukuthunyelwa kwemfucuza kagesi evela emazweni athuthukile iye emazweni asathuthuka. Imfucuza yashiswa endaweni evulekile ukuze kukhishwe izinsimbi. Nakuba kuye kwathathwa izinyathelo zokuqeda lo mkhuba, kusekhona ukukhathazeka mayelana nezintambo ezilahlwa ngendlela efanele. .
Lapha, uhulumeni wami wendawo unezindawo zokuvuselela izinto ezihlanganisiwe, bese udlulisela izinto ezisetshenzisiwe ezihleliwe ezinkampanini ezikhethekile zokuvuselela izinto. Ngezintambo ezimbozwe nge-PVC, ziyasikwa ukuze kuhlukaniswe ithusi nepulasitiki, bese ipulasitiki iyabola ukuze kukhiqizwe izinto zokusetshenziswa ze-hydrocarbon embonini yamakhemikhali.
Esikhaleni sami sokugenca, sizobamba iqembu elisebenzayo ukuze sinciphise inqwaba yekhebula ibe yisilinganiso esilawulekayo. Sibone ukudlula kwesikhathi singazi, yize uBrian Benchoff akubize ngokuthi yiHackaday eminyakeni embalwa edlule. Ngokungagwemeki eminyakeni embalwa kamuva, sizothola i-SCSI peripheral futhi sizisole ngokulahla lawo makhebula e-SCSI, kodwa uma sibheka isikhala esizosithola, ngicabanga ukuthi sizothatha ingozi. Umbuzo uwukuthi, akunjalo?
Kufanele uvule isikhwama sami seminyaka engama-30 esandleni sami esibandayo... Ngisebenze ku-AV, POS, ezinkampanini kanye naku-IT yezempilo futhi ngithole ikhebula... (nge-Ram, i-ISA modem noma i-2): P
"Ngakho-ke noma i-SCSI drive yami yokugcina noma i-VGA monitor isiyisusile le coil ebulalayo, ngisalokhu ngibambelele kukhebula, uyazi, uma kwenzeka."
Ngizibonile ezinye nge-HDMI/DisplayPort, kodwa ngisho namaseva amasha asenayo i-VGA (EG, HP DL380 Gen10). Akekho ofuna ukulahla (i-adaptha esiyithengile) wonke ama-KVM asesegumbini leseva. (Noma uma ungakwazi ukukhokhela i-KVM, ungasebenzisa "isibonisi esiseduze ne-rack enekhebula elide kakhulu"). Kodwa-ke, i-USB ithathe indawo ye-port ye-PS2 ngempumelelo, ngakho-ke ngisola ukuthi ekugcineni sizoyiqeda i-VGA.
Uma intengo ye-adaptha ye-HDMI ingaphansi kwe-$5 microcontroller ofuna ukuyisebenzisa, ngiyavuma ukuthi i-VGA isiphelelwe yisikhathi.
Ungathenga eyodwa ku-AliExpress ngo-$3.75 ngokuthunyelwa kwamahhala. Ngicabanga ukuthi sekuyisikhathi sokuba abantu abaningi baqhubekele phambili. https://www.aliexpress.com/item/32947446707.html

Ngizame ukuxhuma i-HDMI ku-LCD yami kukhonsoli eyakhiwe yi-FreeNAS, kodwa ayisebenzanga kahle. Kwadingeka ngithenge ikhebula le-VGA esitolo sendawo sama-geek ngo-$5, futhi manje sengingakwazi ukuhamba futhi. Ha ha
Amakhompyutha e-DIY afana namakhompyutha e-Arduino namabhodi okuthuthukisa i-FPGA asasebenzisa i-VGA, ngoba ama-resistor ambalwa angakhiqiza isignali yevidiyo ye-analog enhle. Kodwa-ke, kumelwe ukuthi ngiyazibuza ukuthi i-DVI-A iyahambisana yini nezintambo, noma okungenani ilula kanjalo?
Izintambo ze-VGA zisasebenza ekuxhumeni amaphrojektha edatha kuma-laptop, ngoba izintambo ze-HDMI ezinde zibuthakathaka - ziyasebenza noma azisebenzi. Isignali ye-VGA ibukeka ingacacile, kodwa akekho ozoqaphela.
Ngithenge izandiso eziningana ze-EMI VGA esitolo sesibili esisetshenzisiwe ngempelasonto edlule, ngasinye ngo-$0.50. Kodwa angitholanga noma yimaphi amadokhumenti abo ngokusesha kwi-inthanethi.
"Ukuhlanganisa" akusizi ngalutho. Kodwa uma uzihlukanisa, uzoba nezintambo eziningi "ezikhululekile". Intambo eqinile ilungele ukwenza amabhodi okusika noma ama-prototype ahlala njalo. Ama-core aqinile awavamile, futhi ezimweni eziningi angcono kune-core eqinile. Ifaneleka kakhulu ukuxhumanisa ama-connection enziwe ngokwezifiso.
Ungahlanganisa futhi imicu eminingana enemibala, uyijike ibe yiluphu, bese ugoqa iziphetho ukuze wakhe i-spiral efana nembali. Eminyakeni engaba ngu-4 edlule, ngathola i-
Woza lapha uzolanda lokhu. Kungumthombo oshibhile kakhulu wezintambo eziningi ezinemibala ehlukene zokuxhuma. Angifuni ukuthenga izikulufo ezingu-40 zemibala ehlukene, kodwa ngezinye izikhathi ngidinga ukulungiselela imibala eminingi yephrojekthi, bese ngithola enye yalezi zindala bese ngiyikhipha.
Uma uthola idrayivu endala ye-SCSI, inselele iwukuthi ngabe uhlelo lwakho lunesilawuli esisebenzayo, isofthiwe esekela leso silawuli, kanye nekhebula elifanele lokuzixhumanisa - lesi siphelo se-SCSI kwesinye isiphelo se-SCSI...
Eminyakeni embalwa edlule, lapho ngithola idrayivu endala okungenzeka ukuthi angizange ngiyisebenzise iminyaka engaphezu kweyi-10, ngaphahlazeka. Ngachitha ihora noma amabili ngifuna imishini yokuxhuma kuyo, uyazi, ukuze nje ngibone ukuthi kunani kuyo. Ngabe sengiqaphela ukuthi bengingayisebenzisi ukwenza lutho iminyaka eminingi, futhi impendulo yayisobala ukuthi "Anginandaba"
Ngithole izintambo ezindala kanye nemithombo emihle yezintambo (yebo, ngiyazi ukuthi zenziwe ngale nto, kodwa akuzona zonke "izintambo" ezifanayo).
Intambo ekhebula le-SCSI esithombeni iwusizo kakhulu - ingaba yi-conductor yethusi yangempela ene-insulation enhle ngemibala eminingi - ifaneleka kakhulu ekwenzeni izinto, futhi ingcono kune-foil yethusi enkabeni ye-nylon, njengoba injalo namuhla.
Kodwa noma kunjalo, udinga malini? Muva nje, ngidlule ebhokisini lami lekhebula futhi ekugcineni ngathola izintambo ezimbalwa ezinhle zokuxhuma okuningi (ezingahlukaniswa zibe izintambo ngazinye ngemva kokususa ishelufu). Okunye akufanelekile ngempela ukulungiswa. Inani lesikhala ngemva kokususa amabhokisi amabhange angu-3, ​​4, noma 5 agcwele izintambo liyimbuyiselo enhle.
"Ngabe sengibona ngokuzumayo ukuthi bengingayisebenzisi ukwenza lutho iminyaka eminingi, futhi impendulo yayisobala ukuthi "Anginandaba" "
Nginama-IDE drive ayisithupha alindele ukuthi ngiwafune. Ngiyaqiniseka ukuthi kunezithombe zedijithali (ezinye zazo) okufanele zibuyiselwe.
Noma kunjalo, imishini eminingi ekhethekile (njengemishini yezokwelapha) ivame ukudinga izingxenye ezindala ukuze iqhubeke isebenza. Eminyakeni engaba ngu-15 eyedlule, umuntu engimaziyo wangibuza ukuthi uyazi ukuthi angayitholaphi i-hard drive engu-20 Meg. (IIRC, udinga i-ST-225)
Kunamadivayisi amaningana amadala e-synthesizer asebenzisa i-SCSI. I-RaSCSI inhle kakhulu, kodwa ukuze isebenze, empeleni ngidinga _ukuthenga_ ikhebula le-SCSI. 2018!
(Empeleni, azizimbi. Zitholakala esitolo sendawo esiku-inthanethi ngama-$10 futhi zizolethwa ezinsukwini ezimbalwa. Asikho isizathu sokuthenga izintambo eziningi.)
Ngisenayo i-ST-225 kanye ne-ST-251 (40MB!) etholakala ku-286 endala. Umsindo wokuzungeza kwazo uyangikhumbuza izikhathi zakudala.
Ngemva kokugcina izinto zami ezindala ze-scsi unyaka owodwa kuya kwemibili, ngagcina ngizilahlile, kodwa angizange ngizisebenzise ngempela, kwathi ngemva kwezinyanga ezimbili, othile wanginika ikhadi le-SCSI kanye ne-hard drive A2000 enephutha.
Lena indaba yami. Njalo lapho ngizinqoba ekugcineni futhi ngilahla lokho engikuqongelele iminyaka (noma amashumi eminyaka) zingakapheli izinyanga eziyisithupha, ekugcineni ngiyakuthola ukusetshenziswa kwakho futhi angisayiphathi.
Ngalahla i-Zip drive yokugcina emgqonyeni kadoti, kwathi ngosuku olulandelayo ngathola isicelo sokukopisha idatha ebhokisini eligcwele ama-Zip disk. Njengomsebenzi okhokhelwayo, ngaba ngumtshuzi we-dumpster nge-dumpster yami.
Ikhibhodi negundane sekuphelelwe yizintambo, njengoba kunjalo nange-inthanethi, futhi ungathola uhlelo olunezintambo zevidiyo nezikagesi kuphela! (Ku-Mac, lezi zingase zibe yikhebula elifanayo)
Ngaphambi kwesizukulwane sesi-3, ama-hard drive e-M.2 ayeyilungiselelo elijwayelekile kubhodi lomama, futhi ayefakwa njengekhadi le-wifi kukhompyutha ephathekayo. Enye ikhebula ayikho.
I-DisplayPort yilapho isetshenziswa khona kuvidiyo. I-Thunderbolt iyafinyelela ezingeni elifanele. Ungakhetha ukuthumela idatha yembobo yokubonisa noma i-PCIe, bese uhlomisa isibonisi noma i-GPU yangaphandle.
Okungahlobene nesihloko: Nginezaphulelo ezithile kumamodeli amadala e-Lenovo Tiny, i-M72e M92p M93p M900 M700, njll. Uma ufuna ukuhlanya, i-P320 P300 inekhadi le-PCIe langempela elinokukhishwa kwevidiyo okungu-4x (+2 ngaphakathi kwe-iGPU)
Cishe 7"x7"x1.5" futhi kusetshenziswa amaprosesa edeskithophu angempela. Kuyamangalisa! (Ngiyazi ukuthi ekuqaleni ayeyiprosesa engavamile enamandla aphansi, kodwa ngikholwa ukuthi amaprosesa avamile angasebenza, mhlawumbe asebenzise i-throttle stop noma i-Intel XTU ukwehlisa i-voltage. I-chip yami yamandla aphansi engu-4570t isebenzisa ama-watts angu-40 ku-turbocharger, yize iyi-chip engu-35w. Ngakho ngandise i-turbo tdp yaba ngu-40 futhi ngayinciphisa ngama-millivolts angu-60, ngiyigcina ikhulisa i-turbo engu-36-watt Ukucindezela. Uma ufuna uhlelo olushibhile, ngikholwa ukuthi ungayandisa i-chip yedeskithophu engu-51w ibe ngu-40-45w, noma usebenzise i-chip yesivinini esiphansi engeyona i-turbo)
Cha...akuwona wonke amakhibhodi namagundane angenantambo. Yebo, kukhona amakhibhodi namagundane angenantambo kulabo abawadingayo... kodwa amaningi anezintambo, futhi kuye ngohlelo lokusebenza, amakhibhodi/amagundane anezintambo angcono ngezindlela eziningi.
Akusekho ngoba zixhunywe nge-USB, ngoba zikhawulela izinga lokuvuselela ku-125 Hz, futhi awusakwazi ukwenza i-n-key rollover. Isizathu ukuthi i-PS/2 idlulisela ikhodi yokuvula/yokuvala, kuyilapho i-USB ibuyekeza inani lokhiye elishintshile, futhi kunezinkinobho eziyisithupha kuphela ezingabuyekezwa ngohlaka ngalunye.
Ngokuphambene nalokho, i-PS/2 port ngokuyisisekelo iyi-serial port esebenza ngesilinganiso "sokuvuselela" esingaba ngu-1500 Hz, ngoba lesi isikhathi esithathayo ukuthi isibuyekezo sekhodi sidlule. I-host igcina umkhondo wokuthi yiziphi izinkinobho ezicindezelwe noma ezingacindezelwe.
Ngenxa yalokho, wonke amakhibhodi (namagundane) namuhla ancishiswa kakhulu yi-USB futhi awanayo inzuzo yangempela ngaphezu kokusetshenziswa kwe-wireless okuklanywe kahle.
Kimi, isici esimangalisayo sekhibhodi negundane elinezintambo ukuthi alikho ibhethri lokushaja kabusha noma ukulishintsha.
Igundane lami elinezintambo ngezinye izikhathi liyabuhlungu futhi liphuke ngemuva kwethreyi yekhibhodi. Kodwa lokhu kungcono kakhulu kunokuvumela indodakazi yami ukuthi ithathe igundane elingenantambo, ngoba lilahlekelwe yilo!
Kumagundane, umehluko awukho kakhulu, ngoba indlela ikhompyutha efunda ngayo igundane le-PS/2 ihlukile kancane. Ithumela ukuphazamiseka ngemvamisa engu-200 Hz, ngakho-ke igundane elinezintambo ze-USB alisheshi kangako, futhi ngenxa yezigaba ezahlukene ze-HID, lingasethwa ezingeni lokuvuselela elingu-1000 Hz.
Ngashintshela kugundane elingenantambo cishe ngasekupheleni kwawo-1990, noma mhlawumbe kwakusekuseni kakhulu. Njengoba ibhethri lami legundane seliphelile, ngaqalekisa futhi ngakhubeka ezinqamulelini zokuhlanganisa ukhiye iminyaka embalwa. Ngemva kokuba sengikhulile, ngawuyeka lowo mkhuba. Manje ngisebenzisa igundane elingenantambo kuphela kumadivayisi aphathekayo njengezingcingo noma amathebulethi.
