Mushure mekushandisa laptop kwemakore anopfuura gumi, ndakadzokera kukombiyuta yedesktop mwedzi mishoma yapfuura. Computer yekambani yekare uye monitor hombe yescreen yakafara zvakaiswa pachigadziko, pamwe chete nembeva yakakodzera uye IBM Model M yakavimbika yandakashanda nayo kwemakumi emakore. Kamwe kamwe, ergonomics yenzvimbo yangu yebasa yakava nani nekuti handichadi kukotama zvishoma kuti ndione skrini.
Makomputa ekare edesktop akabva kare. Ndinofunga kuti ine vakwikwidzi veAMD vanokwikwidzana nePentium 4, uye kana ndichiyeuka zvakanaka, ndangariro yayo ye512 MB inoonekwa seinokosha. Kumashure, ine seti yemasoketi akasiyana zvachose nesoketi yangu itsva, seti yemaports eserial, SCSI port, uye parallel printer port. Mukati mechassis, madhiraivha ayo akasiyana-siyana anoshumirwa neseti yetambo dzeribhoni. Inotozvirumbidza nefloppy drive. Kusiyana neizvi, waya dzezvigadzirwa zvayo zvinotsiva dzakareruka zvikuru, uye saizi yeconnector idiki zvikuru. Mapulagi eUSB akati wandei netambo yenetwork, pamwe neSATA yemadhiraivha ayo edhisiki. Nguva yakakura yekubatana kwakawanda yapera, uye vazhinji vedu tinogona kuzorora.
Dambudziko netambo dzakawanda nderekuti dzaiwanzodhura panguva iyoyo, saka ndichiri kufunga kuti dzine kukosha kwakati. Saka kunyangwe SCSI drive yangu yekupedzisira kana VGA monitor yakabvisa coil iyi inouraya, ndichiri kurembera patambo, unoziva, kana zvichibvira. Pane bhokisi rakafukunuka rakavigwa pasherufu pane imwe nzvimbo, kana kuti kana uri munzvimbo yangu yekugadzira muMilton Keynes, mabhokisi akawanda akafukunuka. Ndisati ndapedza kuchenesa, ngatinyatsoongorora zvinhu izvi, tichifunga kuti hauzogumburwi nekuendesa cutter kune dzimwe tambo dzakakwana. Skena boka, uye akawanda akakamurwa mumapoka mana makuru. Parallel SCSI, VGA, parallel printer, uye nekuti iyi iSCART multi-channel audiovisual cable yakanyorwa muEurope.
Sezvaungatarisira kubva pa parallel interface, tambo yeSCSI inotora chimiro chewaya dzakawanda, asi kana ukanyatsotarisa mukati me plug, zvinoshamisa kuti hapana shielding kana twisted pair pakati pewaya. Parallel printer cable ine chimiro chakafanana: ingori 8-bit port pane host. Kune rumwe rutivi, VGA neSCART cables dzine coaxial shielded conductors dzemasaini evhidhiyo uye dzimwe single wards dzemasaini ekudzora.
Pandaifunga nezvekuti ndingashandise sei tambo dzakadaro ndipo pandakaona kuti tafambira mberi zvakadii kubva panguva yekushandiswa kwetambo dzakawanda. USB ikozvino inovhara zvishandiso zvakawanda zvedesktop zvaimboshandiswa neparallel SCSI, parallel, uye serial ports, uye dzinenge dzese audiovisual connections dziri kuchinja nekukurumidza kuenda kuHDMI. Idzi fast serial interfaces dzinopa data rakawanda netambo dzemhangura shoma.
Zvinoita sekuti kune tambo dzakawanda dzandakaona kwese kwese, uye dzave dzisina basa. Kusiyana nedzimwe shanduko dzetekinoroji, dzakadai sekubva kumachubhu evacuum kusvika kumatransistors, kushanda kwadzo hakuna kudzikira netekinoroji itsva, saka hupenyu hwadzo hwekushanda hahuna kupfuura hupenyu hwadzo hwekushanda. Pane kudaro, kana tekinoroji yadzo yasvika pakakwirira, dzinobva dzava e-waste, kwatinogona kuwana kwadzinobva kukosha kwadzo. Kana uine tambo dzakawanda dzeSCSI kune imwe nzvimbo, unodzibata here nekuti unofunga kuti uchadzida zvakare rimwe zuva?
Kupisa tambo kuti tiwane mhangura, 2018, Accra, Ghana. Muntaka Chasant [CC BY-SA 4.0]. Saka tinofanira kuitei? Dzinogona kushandiswa kune zvimwe zvinangwa here? Chero zvazvingava, ndiani anoshandisa waya ye40-way bundle kana kuti tambo dzakawanda dzecoaxial dzisina kunaka mazuva ano? Ndingada kunzwa pfungwa dzenyu mumashoko enyu.
Panguva imwe chete, ndine tambo dzakawanda dzekugadzirisa nadzo, uye iri ndiro dambudziko. Mhangura yadziri mairi inokosha, asi kazhinji, zvinhu zvavo zvinodzivirira kupisa iPVC. Kudzokorodza kungave kunetsa. Kana kushanda zvakanaka kwekupisa kwakaderera, kuchaburitsa makemikari ane chepfu. Mumakore apfuura, kwave kune zviitiko zvakawanda zvine chekuita nekutengeswa kwemarara emagetsi kubva kunyika dzakabudirira kuenda kunyika dzichiri kusimukira. Marara acho aipiswa pachena kuti abudise simbi. Kunyangwe matanho akatorwa kuti tsika iyi ipere, kuchine kunetsekana nezvekuti tambo dzinoraswa zvine hungwaru.
Pano, hurumende yangu yemuno ine nzvimbo dzekudzokorodza zvinhu, uye yozoendesa zvinhu zvakadzokororwa kumakambani ane hunyanzvi hwekudzokorodza zvinhu. Kune tambo dzakaputirwa nePVC, dzinochekwa-chekwa kuti dziparadzanise mhangura nepurasitiki, uye purasitiki yacho inoora kuti igadzire zvinhu zvehydrocarbon zvinoshandiswa muindasitiri yemakemikari.
Munzvimbo yangu yekuvhima, tichabata boka rekushanda kuti tideredze huwandu hwetambo kusvika padanho rinogoneka. Takasangana nenguva inopfuura tisingazive, kunyangwe Brian Benchoff akaitumidza kuti Hackaday makore mashoma apfuura. Zvingangoitika kuti makore mashoma gare gare, tichawana SCSI peripheral tozozvidemba nekurasa tambo idzodzo dzeSCSI, asi tichifunga nezvenzvimbo yatichawana, ndinofunga tichatora njodzi. Mubvunzo ndewokuti, muchazviita here?
Unofanira kuvhura bhegi rangu remakore makumi matatu kubva muruoko rwangu rwakaoma... Ndakamboshanda muAV, POS, makambani nezvehutano IT uye ndakawana waya... (neRam, modem yeISA kana 2): P
"Saka kunyangwe SCSI drive yangu yekupedzisira kana VGA monitor yakabvisa coil iyi inouraya, ndichiri kurembera patambo, unoziva, kana zvikaitika."
Ndakaona mamwe aine HDMI/DisplayPort, asi kunyange maserver matsva achiri neVGA (EG, HP DL380 Gen10). Hapana anoda kurasa (adapta yatakatenga) maKVM ese achiri mukamuri reserver. (Kana kuti kana usingakwanise kutenga KVM, unogona kushandisa "display iri padyo nerack ine tambo refu kwazvo"). Zvisinei, USB yakabudirira kutsiva PS2 port, saka ndinofungidzira kuti tichazobvisa VGA pakupedzisira.
Kana mutengo weadapta yeHDMI uri pasi pemadhora mashanu emadhora ekuAmerica aunoda kushandisa, saka ndinobvuma kuti VGA yagara iri yekare.
Unogona kutenga imwe paAliExpress ne$3.75 uchitumira mahara. Ndinofunga kuti yasvika nguva yekuti vanhu vazhinji vaenderere mberi nehupenyu hwavo. https://www.aliexpress.com/item/32947446707.html

Ndakaedza kubatanidza HDMI kuLCD yangu pakombuta yakagadzirwa neFreeNAS, asi hazvina kushanda zvakanaka. Ndakatofanira kutenga tambo yeVGA kubva kuchitoro chegeek chemunharaunda nemadhora mashanu, uye ikozvino ndinogona kudzokera zvakare. Ha ha
Makomputa ekugadzira ega akadai seArduino makombiyuta nemabhodhi ekugadzira eFPGA achiri kushandisa VGA, nekuti maresistor mashoma anogona kugadzira chiratidzo chevhidhiyo cheanalog chakanaka. Zvisinei, ndinofanira kunge ndichishamisika kana DVI-A inoenderana netambo, kana kuti zviri nyore kudaro?
Tambo dzeVGA dzichiri kubatsira pakubatanidza mapurojekita edata kumalaptop, nekuti tambo refu dzeHDMI hadzina kusimba - dzinoshanda kana kuti hadzishande. Chiratidzo cheVGA chinongoita sechisina kusimba, asi hapana achazviona.
Ndakatenga maEMI VGA extenders akawanda kuchitoro chechipiri chekushandisa patsva vhiki rapfuura, rimwe nerimwe richitengwa ne$0.50. Asi handina kuwana chero magwaro avo kuburikidza nekutsvaga paInternet.
"Kubatanidza" hazvibatsiri zvakanyanya. Asi kana ukazviparadzanisa, unenge uine tambo dzakawanda "dzisina muripo". Waya yakasimba yakanakira kugadzira mabhodhi ekugadzira mapuranga kana ma prototypes echigarire. Macores akasungirirwa haawanzo kuwanikwa, uye kazhinji ari nani pane macores akaomarara. Yakakodzera kubatanidza maconnections akajairwa.
Unogona zvakare kubatanidza shinda dzakasiyana-siyana dzine mavara, wodzipeta kuita denderedzwa, wozopeta magumo acho kuti aite denderedzwa rakaita seruva. Makore angangoita mana apfuura, ndakawana
Uyai pano muzowana izvi. Ndiyo nzvimbo yakachipa yekubatanidza waya dzakawanda dzine mavara akasiyana. Handidi kutenga 40 spools dzemavara akasiyana, asi dzimwe nguva ndinofanira kugadzirira mavara akawanda epurojekiti, uye ndozowana imwe yeakwegura aya ndoibvisa.
Kana ukaona dhiraivha yekare yeSCSI, dambudziko nderekuti system yako ine controller inoshanda here, software inotsigira controller iyoyo, uye tambo chaiyo yekubatanidza - iyi SCSI mugumo kune imwe mugumo weSCSI... .
Makore mashoma apfuura, pandakawana dhiraivha yekare yandaisagona kushandisa kwemakore anopfuura gumi, ndakadonha. Ndakapedza awa imwe kana maviri ndichitsvaga michina yekubatanidza nayo, unoziva, kuti ndingoona kuti chii chiri pairi. Ipapo ndakaona kuti ndakanga ndisina kuishandisa kwemakore, uye mhinduro yacho yaiva pachena kuti "Handina basa nazvo" 
Ndakawana tambo dzekare uye manyuko akanaka ewaya (hongu, ndinoziva kuti dzakagadzirwa nezvinhu izvi, asi hadzisi "waya" dzese dzakafanana).
Waya iri muSCSI cable iri mumufananidzo inobatsira zvikuru - inogona kunge iri conductor chaiyo yemhangura ine insulation yakanaka yemavara akasiyana - yakakodzera kugadzira zvinhu, uye iri nani pane copper foil iri pakati penylon, sezvairi nhasi. Kufanana newaya dzakawanda.
Asi kunyangwe zvakadaro, unoda marii? Nguva pfupi yapfuura, ndakapfuura nepabhokisi rangu remagetsi ndikawana tambo dzakanaka dzekubatanidza dzakawanda (dzinogona kupatsanurwa kuita waya dzakasiyana mushure mekubvisa sheath). Dzimwe hadzina kukodzera kugadziriswa. Nzvimbo yakawanda mushure mekubvisa mabhokisi emabhanga matatu, mana, kana mashanu azere netambo ipfungwa yakanaka.
"Ipapo ndakangoerekana ndaona kuti ndakanga ndisina kuishandisa kuita chero chinhu kwemakore, uye mhinduro yacho yaiva pachena kuti "Handina basa nazvo" "
Ndine maIDE drives matanhatu akandimirira kuti ndiatsvage. Ndine chokwadi chekuti kune mamwe mapikicha edhijitari (mamwe acho) akakodzera kudzoserwa.
Zvisinei, michina yakawanda yakagadzirwa (yakadai semidziyo yekurapa) inowanzoda zvikamu zvekare kuti irambe ichishanda. Makore angangoita gumi nemashanu apfuura, mumwe munhu wandinoziva akandibvunza kana aiziva kwaaigona kuwana hard drive ye20 Meg. (IIRC, anoda ST-225)
Kune michina yekare yakawanda ye synthesizer inoshandisa SCSI. RaSCSI yakanaka, asi kuti ishande, ndinofanira kutenga tambo yeSCSI. 2018!
(Chaizvoizvo, hazvina kuipa. Zvinowanikwa pachitoro chepamhepo chemunharaunda nemadhora gumi uye zvichaunzwa mumazuva mashoma. Hapana chikonzero chekuunganidza tambo dzakawanda.)
Ndichiri neST-225 neST-251 (40MB!) dziri mu286 yekare. Ruzha rwekutenderera kwadzo runondishamisa zvikuru.
Mushure mekuchengeta zvinhu zvangu zvekare zveSCSI kwegore rimwe kusvika maviri, ndakazozvirasa, asi handina kuzombozvishandisa, uye mushure memwedzi miviri, mumwe munhu akandipa kadhi reSCSI nehard drive A2000 yakanga yakanganisa.
Iyi ndiyo nyaya yangu. Nguva dzese pandinozopedzisira ndazvikunda ndorasa zvandave ndichiunganidza kwemakore (kana makumi emakore) mukati memwedzi mitanhatu, ndinozopedzisira ndawana kushandiswa kwazvo uye handisisina.
Ndakakanda Zip drive yekupedzisira mugaba remarara, uye zuva rakatevera ndakagamuchira chikumbiro chekukopa data kubva mubhokisi rakazara maZip disks. Sebasa rinobhadharwa, ndakava munyudziri wemadumpster mudumpster yangu.
Kiyibhodhi nemouse zvave kushanda pasina waya, pamwe chete neInternet, uye unogona kuwana system ine tambo dzevhidhiyo nemagetsi chete! (PaMac, idzi dzinogona kunge dziri tambo imwe chete)
Chizvarwa chechitatu chisati chasvika, madhiraivha eM.2 ndiwo aive akajairwa pabhodhi reamai, uye aiiswa sekadhi rewifi mulaptop. Hapana imwe waya.
DisplayPort ndiyo inoshandiswa pavhidhiyo. Thunderbolt iri kushanda zvakanyanya. Unogona kusarudza kutumira data re display port kana PCIe, uye woisa display kana GPU yekunze.
Nyaya isina kunaka: Ndine zvimwe zvakaderedzwa mutengo pamhando dzekare dzeLenovo Tiny, M72e M92p M93p M900 M700, nezvimwewo. Kana uchida kupenga, P320 P300 ine kadhi rePCIe rine vhidhiyo inobuda ka4x (+2 dziri mubhodhi kubva kuiGPU)
Inenge 7"x7"x1.5" uye inoshandisa mapurosesa chaiwo edesktop. Zvinoshamisa! (Ndinoziva kuti pakutanga dzaive dzisingawanzoitiki mapurosesa ane simba shoma, asi ndinotenda kuti mapurosesa akajairwa anogona kushanda, pamwe kushandisa throttle stop kana Intel XTU kudzikisa voltage. Chip yangu ye4570t ine simba shoma inoshandisa 40 watts pa turbocharger, kunyangwe iri chip ye35w. Saka ndakawedzera turbo tdp kusvika 40 ndikaidzikisa ne60 millivolts, zvichiita kuti iwedzere 36-watt turbo. Kana uchida system yakachipa, ndinotenda kuti unogona kuwedzera 51w desktop chip kusvika 40-45w, kana kushandisa chip isina turbo low-speed)
Kwete...haasi makiyibhodhi nemakonzo ese asina waya. Ehe, kune makiyibhodhi nemakonzo asina waya kune avo vanoada... asi akawanda ane waya, uye zvichienderana nekushandisa, makiyibhodhi/makonzo ane waya ari nani munzira dzakawanda.
Hazvichashandi nekuti zvakabatana kuburikidza neUSB, nekuti zvinoderedza mwero wekuzorodza kusvika pa125 Hz, uye hauchakwanise kuita n-key rollover. Chikonzero ndechekuti PS/2 inotumira kodhi yekudzima/kudzima, ukuwo USB ichigadzirisa kukosha kwekiyi yakachinja, uye kune makiyi matanhatu chete anogona kugadziriswa pafuremu imwe neimwe.
Kusiyana neizvi, PS/2 port inonyanya kushanda ne "refresh" rate inosvika 1500 Hz, nekuti iyi ndiyo nguva inotora kuti code update ipfuure. Host inochengeta mabhatani api akadzvanywa kana asina kudzvanywa.
Nekuda kweizvozvo, makiyibhodhi ese (nemakonzo) nhasi anoderedzwa zvakanyanya neUSB uye haana mukana wechokwadi kupfuura mashandisirwo ewireless akagadzirwa zvakanaka.
Kune ini, chinhu chinoshamisa chekhibhodi nemouse zvine waya ndechekuti hapana bhatiri rekuchaja kana kutsiva.
Mbeva yangu ine waya dzimwe nguva inorwadza uye inotsvedza kubva kumashure kwetireyi yekhibhodi. Asi izvi zviri nani pane kurega mwanasikana wangu achitora mbeva isina waya, nekuti akarasikirwa nayo!
Kune mbeva, musiyano wacho hausi mukuru, nekuti maverengero anoita mbeva yePS/2 pakombiyuta akasiyana zvishoma. Inotumira kukanganiswa pafrequency ye200 Hz, saka mbeva yeUSB haina kunonoka, uye nekuda kwemakirasi akasiyana eHID, inogona kuiswa pa refresh rate ye1000 Hz.
Ndakachinja kushandisa mbeva isina waya kumagumo kwema1990, kana kuti pamwe kwaive kutanga kwazvo. Sezvo bhatiri rembeva rangu rapera, ndakatuka uye ndakagumburwa nekushandisa makiyi ekupfupisa makiyi kwemakore mashoma. Mushure mekukura, ndakarega kushandisa zvinhu izvozvo. Iye zvino ndinoshandisa mbeva isina waya chete pamidziyo inotakurika senge nharembozha kana mapiritsi.
