isixhumi se-hd15

Emva kokusebenzisa ilaptop iminyaka engaphezu kweshumi, ndabuyela kwikhompyutha yedesktop kwiinyanga ezimbalwa ezidlulileyo. I-PC encinci yenkampani yangaphambili kunye nesikrini esikhulu esibanzi zibekwe kwisitendi, kunye nemawusi efanelekileyo kunye ne-IBM Model M ethembekileyo endiyisebenzele kangangeminyaka emininzi. Ngequbuliso, i-ergonomics yendawo yam yokusebenza yaba ngcono kuba andisadingi kugoba kancinci ukuze ndibone isikrini.
Iikhompyutha zangaphambili zedesktop zavela kwixesha elidlulileyo. Ndicinga ukuba inazo naziphi na ii-AMD ezikhuphisana nePentium 4, kwaye ukuba ndikhumbula kakuhle, imemori yayo ye-512 MB ithathwa njengebaluleke kakhulu. Ngasemva, ineseti yeesokhethi ezahlukileyo ngokupheleleyo kwisokhethi yam entsha, iseti yeeports ezilandelelanayo, iport ye-SCSI, kunye neport yeprinta ehambelanayo. Ngaphakathi kwi-chassis, iidrives zayo ezahlukeneyo zikhonzwa yiseti yeentambo zeribhoni. Ikwaqhayisa nge-floppy drive. Ngokwahlukileyo koko, iingcingo zeemveliso zayo ezilandelayo zilula kakhulu, kwaye ubungakanani besixhumi buncinci kakhulu. Iiplagi ezininzi ze-USB kunye nentambo yenethiwekhi, kunye ne-SATA yeedrives zayo zediski. Ixesha elikhulu lokunxibelelana okuninzi liphelile, kwaye uninzi lwethu lunokukhululeka.
Ingxaki ngeentambo ezininzi kukuba zazidla ngokuba zibiza kakhulu ngelo xesha, ngoko ke ndisacinga ukuba zinexabiso elithile. Nangona i-SCSI drive yam yokugqibela okanye i-VGA monitor yam isuse le coil ibulalayo, ndisaxhoma kwintambo, uyazi, ukuba kunokwenzeka. Kukho ibhokisi evuvukileyo efihliweyo kwishelufu ndaweni ithile, okanye ukuba ukwindawo yam yokudala eMilton Keynes, kukho iibhokisi ezivuvukileyo. Ngaphambi kokuba ndigqibe ukucoca, masijonge ngokusondeleyo ezi zinto, sicinga ukuba awuyi kukhubeka ngokuthatha i-cutter uye kwezinye iintambo ezigqibeleleyo. Skena inqwaba, kwaye uninzi lwazo lwahlulwe lwangamaqela amane aphambili. I-SCSI eValiweyo, i-VGA, iprinta eValiweyo, kwaye kuba le yintambo ye-SCART multi-channel audiovisual ebhalwe eYurophu.
Njengoko ubuya kulindela kwi-interface ehambelanayo, intambo ye-SCSI ithatha uhlobo lweengcingo ezininzi, kodwa xa ujonga ngaphakathi kwiplagi, into emangalisayo kukuba akukho sibini esikhuselayo okanye esijijekileyo phakathi kweengcingo. Intambo yeprinta ehambelanayo inesakhiwo esifanayo kakhulu: yi-port ye-8-bit kwi-host. Kwelinye icala, iintambo ze-VGA kunye ne-SCART ziqulathe uthotho lwee-coaxial shielded conductors zeempawu zevidiyo kunye nezinye iintambo zodwa zezibonakaliso zolawulo.
Kuxa ndicinga ngendlela yokusebenzisa kwakhona ezi ntambo, ndaqonda ngokwenene ukuba siphi inkqubela phambili esiyenzileyo ukususela kwixesha lee-interfaces ezininzi zekhebula. I-USB ngoku igubungela uninzi lwezixhobo zedesktop ezazikade zikhonzwa yi-SCSI parallel, parallel, kunye ne-serial ports, kwaye phantse zonke ii-audiovisual connections zitshintshela kwi-HDMI ngokukhawuleza. Ezi-interfaces ze-serial ezikhawulezayo zibonelela ngamanani aphezulu edatha ngeentambo zekopolo ezimbalwa.
Kubonakala ngathi kukho iintambo ezininzi endizibonileyo kuyo yonke indawo, kwaye azisenamsebenzi. Ngokungafaniyo nezinye iinguqu zobuchwepheshe, ezifana neetyhubhu ze-vacuum ukuya kwii-transistors, ukusebenziseka kwazo akukanciphi ngeteknoloji entsha, ngoko ke ubomi bazo benkonzo abudlulanga ubomi bazo benkonzo. Ngokwahlukileyo koko, xa ubuchwepheshe bazo bufikelela kwincopho yazo, ngoko nangoko ziba yi-e-waste, apho sinokufumana khona umthombo wexabiso lazo lokuchazwa. Ukuba uneentambo ezininzi ze-SCSI ndaweni ithile, ngaba uyazibamba kuba ucinga ukuba uza kuzifuna kwakhona ngenye imini?
Ukutshisa iintambo zokubuyisa ubhedu, 2018, eAccra, eGhana. Muntaka Chasant [CC BY-SA 4.0]. Ngoko ke simele senze ntoni? Ngaba zingasetyenziselwa ezinye iinjongo? Nokuba yeyiphi na imeko, ngubani osebenzisa i-wire bundle yeendlela ezingama-40 okanye iqela leentambo ze-coaxial ezingalunganga kule mihla? Ndingathanda ukuva uluvo lwakho kwizimvo.
Kwangaxeshanye, ndineentambo ezininzi ekufuneka ndizijongane nazo, kwaye le yingxaki. Ubhedu olunazo luxabisekile, kodwa kwiimeko ezininzi, izinto zazo zokukhusela igesi yiPVC. Ukuphinda kusetyenziswe izinto ezisetyenzisiweyo kunokuba yingxaki. Ukuba ukusebenza kakuhle kokutsha kuphantsi, kuya kukhupha iikhemikhali ezinobungozi. Kwiminyaka edlulileyo, bekukho uthotho lwezityholo ezibandakanya ukuthunyelwa kwenkunkuma ye-elektroniki kumazwe aphuhlileyo ukuya kumazwe asaphuhlayo. Inkunkuma yatshiswa ebaleni ukuze kukhutshwe iintsimbi. Nangona amanyathelo athathiweyo ukuphelisa lo mkhwa, kusekho iinkxalabo malunga neentambo ezilahlwa ngokusesikweni.
Apha, urhulumente wam wasekuhlaleni uneendawo zokusebenzisa izinto ezisetyenzisiweyo, aze emva koko adlulisele izinto ezisetyenzisiweyo ezihleliweyo kwiinkampani ezikhethekileyo zokusebenzisa izinto ezisetyenzisiweyo. Kwiintambo ezigqunywe ngePVC, ziyanqunyulwa ukuze kwahlulwe ubhedu kwiplastiki, emva koko iplastiki iyabola ukuze kuveliswe izinto eziluhlaza ze-hydrocarbon kwishishini leekhemikhali.
Kwindawo yam yokuqhekeza, siza kuba neqela elisebenzayo lokunciphisa inqwaba yeentambo ukuya kwinqanaba elilawulekayo. Sibone ukudlula kwexesha singazi, nangona uBrian Benchoff wayibiza ngokuba yiHackaday kwiminyaka embalwa eyadlulayo. Ngokungathandabuzekiyo emva kweminyaka embalwa, siza kufumana i-SCSI peripheral size sizisole ngokulahla ezo ntambo ze-SCSI, kodwa xa sicinga ngendawo esiza kuyifumana, ndicinga ukuba siza kuthatha umngcipheko. Umbuzo ngulo, akunjalo?
Kuya kufuneka uvule ibhegi yam yeminyaka engama-30 esandleni sam esibandayo... Ndisebenze kwi-AV, POS, kwi-IT yenkampani nakwimpilo kwaye ndifumene intambo... (eneRam, imodem ye-ISA okanye ezimbini): P
"Ngoko ke nangona i-SCSI drive yam yokugqibela okanye i-VGA monitor isuse le coil ibulalayo, ndisabambelele kwintambo, uyazi, ukuba kunokwenzeka."
Ndizibonile ezinye ngeHDMI/DisplayPort, kodwa neeseva ezintsha zisenayo iVGA (EG, HP DL380 Gen10). Akukho mntu ufuna ukulahla (iadaptha esiyithengileyo) zonke iiKVM ezisesegumbini leseva. (Okanye ukuba awukwazi ukuthenga iKVM, ungasebenzisa "isibonisi esikufutshane nerakhi enentambo ende kakhulu"). Nangona kunjalo, i-USB itshintshe ngempumelelo ichweba lePS2, ngoko ke ndicinga ukuba ekugqibeleni siza kuyisusa iVGA.
Ukuba ixabiso le-adaptha ye-HDMI lingaphantsi kwe-$5 microcontroller ofuna ukuyisebenzisa, ndiyavuma ukuba i-VGA iphelelwe lixesha.
Ungathenga enye kwi-AliExpress nge-$3.75 ngokuthunyelwa simahla. Ndicinga ukuba lixesha lokuba uninzi lwabantu luqhubeke nobomi. https://www.aliexpress.com/item/32947446707.html

Ndizamile ukuqhagamshela i-HDMI kwi-LCD yam kwi-console eyakhiwe yiFreeNAS, kodwa ayizange isebenze kakuhle. Kwafuneka ndithenge intambo yeVGA kwivenkile ye-geek yasekuhlaleni nge-$5, kwaye ngoku ndingaya kwakhona. Ha ha
Iikhompyutha ezenziwe ngezandla ezifana neekhompyutha zeArduino kunye neebhodi zophuhliso zeFPGA zisasebenzisa iVGA, kuba iiresistor ezimbalwa zinokuvelisa isignali yevidiyo ye-analog elungileyo. Nangona kunjalo, kufuneka ndizibuze ukuba i-DVI-A iyahambelana neentambo, okanye ubuncinane ilula ngolo hlobo?
Iintambo zeVGA zisaluncedo ekuqhagamsheleni iiprojektha zedatha kwiilaptop, kuba iintambo zeHDMI ezinde zibuthathaka-ziyasebenza okanye azisebenzi. Isignali yeVGA ibukeka incinci, kodwa akukho mntu uya kuyiqaphela.
Ndithenge ii-extenders ezininzi ze-EMI VGA kwivenkile yesibini ethengiswayo ngempelaveki ephelileyo, nganye nge-$0.50. Kodwa andifumananga maxwebhu abo ngokukhangela kwi-intanethi.
"Ukubopha" akuncedi kakhulu. Kodwa xa uzihlulahlula, uya kuba neentambo ezininzi "ezikhululekileyo". Intambo eqinileyo ifanelekile ekwenzeni iibhodi zesonka okanye iiprototypes ezisisigxina. Ii-cores ezixineneyo azixhaphakanga, kwaye kwiimeko ezininzi zingcono kunee-cores eziqinileyo. Ifanelekile kakhulu ekudibaniseni ii-interconnects ezenziwe ngokwezifiso.
Ungadibanisa imisonto enemibala emininzi, uyijike ibe yiluphu, uze ugoqe iziphelo ukuze wenze i-spiral efana nentyatyambo. Kwiminyaka emi-4 eyadlulayo, ndafumana i-
Yiza apha ukuze ufumane oku. Ngumthombo ongabizi kakhulu weentambo ezininzi ezinemibala eyahlukeneyo. Andifuni ukuthenga iispool ezingama-40 zemibala eyahlukeneyo, kodwa ngamanye amaxesha kufuneka ndilungiselele imibala emininzi kwiprojekthi, ndize ndifumane enye yala madoda amadala ndiyikhuphe.
Xa ufumanisa i-SCSI drive endala, umngeni kukuba ingaba inkqubo yakho inesilawuli esisebenzayo na, isoftware exhasa eso silawuli, kunye nentambo efanelekileyo yokuzidibanisa- esi siphelo se-SCSI siye kwesinye isiphelo se-SCSI... .
Kwiminyaka embalwa eyadlulayo, xa ndafumana i-drive endala endingazange ndiyisebenzise kangangeminyaka engaphezu kwe-10, ndawa. Ndachitha iyure okanye ezimbini ndikhangela izixhobo zokuyidibanisa, uyazi, ukuze ndibone ukuba yintoni na ekuyo. Emva koko ndaqonda ukuba bendingayisebenzisi ukwenza nantoni na kangangeminyaka, kwaye impendulo yayicacile ukuba "Andikhathali"
Ndifumene iintambo ezindala kunye nemithombo elungileyo yeentambo (ewe, ndiyazi ukuba zenziwe ngale nto, kodwa ayizizo zonke "iintambo" ezifanayo).
Intambo ekwintambo ye-SCSI emfanekisweni iluncedo kakhulu-isenokuba yi-copper conductor yokwenyani ene-insulation entle enemibala emininzi-ifanelekile kakhulu ukwenza izinto, kwaye ingcono kune-copper foil ekwi-nylon core, njengoko injalo namhlanje.
Kodwa nangona kunjalo, udinga malini? Kungekudala, ndidlule kwibhokisi yam yekhebula kwaye ekugqibeleni ndifumene iintambo ezimbalwa ezintle zoqhagamshelo oluninzi (ezinokwahlulwa zibe ziintambo ezahlukeneyo emva kokususa ishelufu). Ezinye azifanelekanga ukulungiswa. Ubungakanani bendawo emva kokulahla iibhokisi zebhanki ezi-3, 4, okanye 5 ezizele ziintambo yimbuyekezo entle.
"Emva koko ndaqonda ukuba bendingayisebenziselanga ukwenza nantoni na kangangeminyaka, kwaye impendulo yayicacile ukuba "Andikhathali" "
Ndinee-IDE drives ezintandathu ezilindele ukuba ndizikhangele. Ndiqinisekile ukuba kukho iifoto zedijithali (ezinye zazo) ezifanele ukubuyiselwa.
Nangona kunjalo, izixhobo ezininzi ezikhethekileyo (ezifana nezixhobo zonyango) zihlala zifuna izixhobo ezindala ukuze ziqhubeke nokusebenza. Kwiminyaka eli-15 eyadlulayo, umntu endimaziyo wandibuza ukuba uyazi na ukuba angayifumana phi i-hard drive ye-20 Meg. (IIRC, udinga i-ST-225)
Kukho izixhobo ezininzi ezindala ze-synthesizer ezisebenzisa i-SCSI. I-RaSCSI ilungile, kodwa ukuze isebenze, kufuneka ndithenge intambo ye-SCSI. 2018!
(Enyanisweni, azimbi kangako. Ziyafumaneka kwivenkile ekwi-intanethi yasekuhlaleni nge-$10 kwaye ziya kuziswa kwiintsuku ezimbalwa. Akukho sizathu sokuthenga iintambo ezininzi.)
Ndisenayo i-ST-225 kunye ne-ST-251 (40MB!) ekwi-286 endala. Isandi sokujikelezwa kwazo siyamangalisa kakhulu.
Emva kokugcina izinto zam ezindala ze-scsi iminyaka eli-1 ukuya kwemi-2, ekugqibeleni ndazilahla, kodwa andizange ndizisebenzise, ​​emva koko emva kweenyanga ezimbini, umntu wandinika ikhadi le-SCSI kunye ne-hard drive A2000 enengxaki.
Eli libali lam. Ngalo lonke ixesha ekugqibeleni ndizingca kwaye ndilahla oko bendikuqokelele iminyaka (okanye amashumi eminyaka) kwiinyanga ezi-6, ekugqibeleni ndiyifumana indlela yokusebenzisa kwaye andisayi kuba nayo.
Ndaphosa i-Zip drive yokugqibela kwi-trash can, kwaye ngosuku olulandelayo ndafumana isicelo sokukopa idatha kwibhokisi egcwele iidiski zeZip. Njengomsebenzi ohlawulayo, ndaba ngumntywili we-dumpster kwi-dumpster yam.
Ikhibhodi kunye nemawusi azinazingcingo, njengoko kunjalo nge-intanethi, kwaye ungafumana inkqubo eneentambo zevidiyo kunye nombane kuphela! (KwiMac, ezi zisenokuba yintambo efanayo)
Ngaphambi kwesizukulwana sesi-3, ii-hard drive ze-M.2 zaziyi-standard configuration kwi-motherboard, kwaye zazifakwe njengekhadi le-wifi kwi-laptop. Enye intambo ayikho.
I-DisplayPort yindawo esetyenziswa kuyo kwividiyo. I-Thunderbolt iyafikelela kwinqanaba. Ungakhetha ukuthumela idatha yezibuko zokubonisa okanye i-PCIe, kwaye uxhobise isibonisi okanye i-GPU yangaphandle.
Ingxaki encinci: Ndinezaphulelo kwiimodeli ezindala zeLenovo Tiny, iM72e M92p M93p M900 M700, njl. Ukuba ufuna ukuphambana, iP320 P300 inekhadi le-PCIe lokwenyani elinevidiyo ephumayo ka-4x (+2 kwi-iGPU)
Malunga ne-7"x7"x1.5" kwaye zisebenzisa iiprosesa zedesktop zokwenyani. Kuyamangalisa! (Ndiyazi ukuba zaziziiprosesa ezisebenzisa amandla aphantsi ekuqaleni, kodwa ndikholelwa ukuba iiprosesa eziqhelekileyo zinokusebenza, mhlawumbi zisebenzisa i-throttle stop okanye i-Intel XTU ukunciphisa i-voltage. I-chip yam ye-4570t enamandla aphantsi isebenzisa ii-watts ezingama-40 kwi-turbocharger, nangona iyi-chip ye-35w. Ngoko ke ndiye ndayinyusa i-turbo tdp ukuya kwi-40 ndaza ndayihlisa ngee-millivolts ezingama-60, ndayigcina inyusa i-turbo ye-36-watt Uxinzelelo. Ukuba ufuna inkqubo engabizi kakhulu, ndikholelwa ukuba ungayinyusa i-chip yedesktop ye-51w ukuya kwi-40-45w, okanye usebenzise i-chip yesantya esiphantsi engekho kwi-turbo)
Hayi...ayizo zonke iikhibhodi kunye neempuku ezingenazingcingo. Ewe, kukho iikhibhodi ezingenazingcingo kunye neempuku kwabo bazifunayo... kodwa ezininzi zineentambo, kwaye kuxhomekeke kwisicelo, iikhibhodi/iigundane ezinentambo zingcono ngeendlela ezininzi.
Ayisekho kuba ziqhagamshelwe nge-USB, kuba inciphisa izinga lokuhlaziya ukuya kwi-125 Hz, kwaye awusakwazi ukwenza i-n-key rollover. Isizathu kukuba i-PS/2 idlulisela ikhowudi yokuvula/yokucima, ngelixa i-USB ihlaziya ixabiso lesitshixo elitshintshileyo, kwaye kukho izitshixo ezintandathu kuphela ezinokuhlaziywa kwifreyimu nganye.
Ngokwahlukileyo koko, i-PS/2 port ngokusisiseko yi-serial port esebenza ngesantya "sokuhlaziya" esimalunga ne-1500 Hz, kuba le yindlela ethatha ixesha ngayo uhlaziyo lwekhowudi ukuba ludlule. I-host igcina umkhondo wamaqhosha acinezelweyo okanye angacinezelwanga.
Ngenxa yoko, zonke iikhibhodi (kunye neempuku) namhlanje zicothiswa kakhulu yi-USB kwaye azinalo ithuba lokwenene ngaphezu kokusetyenziswa kwee-wireless eziyilwe kakuhle.
Kum, uphawu olubalaseleyo lwekhibhodi kunye nemawusi eneentambo kukuba akukho bhetri yokutshaja okanye yokuyitshintsha.
Impuku yam enentambo ngamanye amaxesha ibuhlungu kwaye ityibilika ngasemva kwetreyi yekhibhodi. Kodwa oku kungcono kunokuvumela intombi yam ithathe impuku engenantambo, kuba ilahlekelwe yiyo!
Kwimouse, umahluko awukho mkhulu kangako, kuba indlela ikhompyutha efunda ngayo imouse yePS/2 yahlukile kancinci. Ithumela ukuphazamiseka kwi-frequency ye-200 Hz, ngoko ke imouse enentambo ye-USB ayicothi kangako, kwaye ngenxa yeeklasi ezahlukeneyo ze-HID, inokubekwa kwizinga lokuhlaziya le-1000 Hz.
Ndatshintshela kwi-mouse engenazingcingo ngasekupheleni kweminyaka yoo-1990, okanye mhlawumbi kwakusekutsha kakhulu. Ekubeni ibhetri yam ye-mouse iphelile, ndaqalekisa ndaza ndakhubeka kwiindlela ezimfutshane zokudibanisa izitshixo kangangeminyaka embalwa. Emva kokuba ndikhulile, ndayeka loo nto. Ngoku ndisebenzisa i-mouse engenazingcingo kuphela kwizixhobo eziphathwayo ezifana neefowuni eziphathwayo okanye iitablet.
