Rau cov neeg feem coob uas siv 8-ntsis hauv tsev computers thaum xyoo 1980s, siv cov kab xev los khaws cov kev pab cuam yog lub cim xeeb ntev.Tsuas yog cov neeg nplua nuj heev tuaj yeem them taus disk drives, yog li yog tias koj tsis nyiam lub tswv yim ntawm tos cov code kom thauj mus ib txhis, ces koj yuav tsis muaj hmoo.Txawm li cas los xij, yog tias koj muaj Sinclair Spectrum, tom qab xyoo 1983, koj muaj lwm txoj kev xaiv, qhov tshwj xeeb Sinclair ZX Microdrive.
Qhov no yog ib hom ntawv tsim los ntawm Sinclair Research.Nws yog qhov tseem ceeb ntawm miniaturized version ntawm lub voj voog tsis kawg lub laub.Nws tau tshwm sim nyob rau hauv daim ntawv ntawm 8-khiav Hi-Fi cassette tshaj kaum xyoo dhau los thiab cog lus tias xob laim-ceev loading lub sij hawm.Seconds thiab ib tug kuj loj cia muaj peev xwm tshaj 80 kB.Cov tswv Sinclair tuaj yeem nrog cov tub loj nyob hauv lub ntiaj teb lub computer hauv tsev, thiab lawv tuaj yeem ua tau yam tsis tau tawg lub txhab nyiaj ntau dhau.
Raws li tus neeg taug kev rov qab los ntawm lub chaw nyiag khoom nyiag khoom ntawm thaj av loj, vim muaj kev sib kis, tsoomfwv Askiv xav kom kuv raug cais tawm ob lub lis piam.Kuv ua nws li ib tug qhua ntawm Claire.Claire yog kuv tus phooj ywg thiab nws tshwm sim los ua qhov kev paub.Prolific 8-ntsis Sinclair hardware thiab software sau.Thaum tham txog Microdrive, nws tsis tsuas yog yuav qee qhov piv txwv ntawm cov tsav thiab software, tab sis kuj tseem muaj cov kab ke sib txuas thiab cov khoom siv microdrive qub.Qhov no tau muab sijhawm rau kuv los tshuaj xyuas thiab rhuav tshem cov kab ke thiab muab cov neeg nyeem nrog kev nkag siab zoo rau hauv qhov khoom siv tsis zoo no feem ntau.
Siv Microdrive.Nws yog ib chav ntsuas kwv yees li 80 mm x 90 mm x 50 mm thiab hnyav dua 200 grams.Nws ua raws tib lub Rich Dickinson styling cues raws li tus thawj roj hmab key Spectrum.Nyob rau pem hauv ntej yog qhib ntawm kwv yees li 32 hli x 7 hli rau kev txhim kho Microdrive daim kab xev cartridges, thiab nyob rau txhua sab ntawm lub nraub qaum yog 14-txoj kev PCB ntug connector rau txuas rau Spectrum thiab daisy-chaining los ntawm kev cai serial tsheb npav Lwm Microdrive muab ribbon cables thiab connectors.Txog yim tsav tuaj yeem txuas rau hauv txoj kev no.
Hais txog tus nqi thaum xyoo 1980s, Spectrum yog lub tshuab zoo heev, tab sis tus nqi ntawm nws qhov kev siv yog tias nws them tsawg heev rau cov khoom siv sib txuas ua ke dhau ntawm nws cov vis dis aus thiab cov kab xev.Qab nws yog ib tug ntug connector, uas ib txwm nthuav tawm ntau lub tsheb npav ntawm Z80, tawm hauv ib qho kev sib txuas ntxiv los ntawm kev nthuav dav module.Tus tswv Spectrum raug cai yuav muaj Kempston joystick adapter hauv txoj kev no, qhov piv txwv pom tseeb tshaj plaws.Spectrum yeej tsis tau nruab nrog Microdrive connector, yog li Microdrive muaj nws tus kheej interface.Sinclair ZX Interface 1 yog ib lub voj voos-zoo li chav tsev uas koom nrog cov ntug txuas ntawm Spectrum thiab ntsia hlau rau hauv qab ntawm lub computer.Nws muab Microdrive interface, RS-232 serial chaw nres nkoj, ib qho yooj yim LAN interface connector siv lub 3.5 hli jack, thiab Replica ntawm Sinclair ntug connector nrog ntau interfaces tso.Qhov kev sib txuas no muaj ROM uas qhia nws tus kheej rau Spectrum lub ROM sab hauv, raws li peb tau taw qhia thaum tus qauv Spectrum tshwm sim ntawm Cambridge Computing History Center, raws li peb txhua tus paub, nws tseem tsis tau ua tiav thiab qee qhov ntawm nws cov haujlwm xav tau tsis tau siv.
Nws yog qhov nthuav los tham txog kho vajtse, tab sis tau kawg, qhov no yog Hackaday.Koj tsis yog xav pom nws xwb, koj xav pom nws ua haujlwm li cas.Tam sim no nws yog lub sij hawm mus disassemble, peb yuav xub qhib lub Microdrive unit nws tus kheej.Ib yam li Spectrum, sab saum toj ntawm lub cuab yeej yog them los ntawm lub phaj txhuas dub nrog lub cim Spectrum logo, uas yuav tsum tau ua tib zoo sib cais los ntawm qhov seem ntawm lub zog ntawm xyoo 1980s nplaum kom nthuav tawm ob lub rooj plaub uas ruaj ntseg rau sab saud.Zoo li Spectrum, nws nyuaj rau ua qhov no yam tsis tau khoov cov txhuas, yog li yuav tsum muaj qee qhov kev txawj ntse.
Nqa lub sab sauv thiab tso tus tsav tsheb LED, cov cuab yeej siv tshuab thiab lub rooj tsav xwm hauv Circuit Court tshwm nyob rau hauv lub zeem muag.Cov neeg nyeem paub yuav pom tam sim ntawd qhov zoo sib xws ntawm nws thiab qhov loj dua 8-khiav suab cassette.Txawm hais tias qhov no tsis yog ib qho derivative ntawm lub system, nws ua haujlwm zoo ib yam.Lub mechanism nws tus kheej yog heev yooj yim.Nyob rau sab xis yog lub micro hloov uas hnov thaum daim kab xev tshem tawm daim ntawv sau tiv thaiv, thiab sab laug yog lub cev muaj zog nrog lub capstan roller.Ntawm kev lag luam kawg ntawm daim kab xev yog lub taub hau daim kab xev, uas zoo li zoo ib yam li qhov koj yuav pom hauv lub kaw lus kaw, tab sis muaj daim kab xev nqaim.
Muaj ob lub PCBs.Nyob rau sab nraum qab ntawm daim kab xev lub taub hau yog 24-pin kev cai ULA (Uncommitted Logic Array, tiag tiag tus thawj coj ntawm CPLD thiab FPGA hauv xyoo 1970s) rau xaiv thiab ua haujlwm tsav.Lwm qhov txuas mus rau hauv qab ib nrab ntawm lub tsev uas muaj ob lub interface txuas thiab lub cev muaj zog hloov hluav taws xob.
Daim kab xev yog 43 mm x 7 mm x 30 mm thiab muaj ib lub voj nruam nws tus kheej lubricating daim kab xev nrog ib tug ntev ntawm 5 meters thiab ib tug ntev ntawm 1.9 hli.Kuv tsis liam Claire rau qhov tsis cia kuv rub ib qho ntawm nws cov ntawv qub qub, tab sis hmoov zoo, Wikipedia muab peb daim duab ntawm daim cartridge nrog rau sab saum toj kaw.Qhov zoo sib xws nrog 8-kab kab xev tau tshwm sim tam sim ntawd.Lub capstan tej zaum yuav nyob rau ntawm ib sab, tab sis tib daim kab xev voj yog pub rov qab mus rau qhov chaw ntawm ib lub reel.
ZX microdrive phau ntawv optimistically hais tias txhua lub cassette tuaj yeem tuav 100 kB ntawm cov ntaub ntawv, tab sis qhov tseeb yog tias ib zaug siv qee qhov txuas ntxiv, lawv tuaj yeem tuav txog 85 kB thiab nce mus rau ntau dua 90 kB.Nws yog qhov ncaj ncees hais tias lawv tsis yog cov tshaj tawm uas ntseeg siab tshaj plaws, thiab cov kab xev nws thiaj li ncav cuag qhov uas lawv tsis tuaj yeem nyeem ntxiv lawm.Txawm tias Sinclair Phau Ntawv Qhia pom zoo kom rov qab cov ntaub nplaum uas siv tau.
Qhov kawg tivthaiv ntawm qhov system yuav tsum tau disassembled yog interface 1 nws tus kheej.Tsis zoo li cov khoom lag luam Sinclair, nws tsis muaj cov ntsia hlau zais hauv qab cov roj hmab taw, yog li ntxiv rau kev ua haujlwm maj mam ntawm kev sib cais sab saum toj ntawm lub tsev los ntawm Spectrum edge connector, nws kuj yog ib qho yooj yim rau disassemble.Sab hauv yog peb lub chips, Texas Instruments ROM, universal instrument ULA es tsis txhob Ferranti project siv los ntawm Spectrum nws tus kheej, thiab me ntsis 74 logic.ULA suav nrog tag nrho cov circuits tshwj tsis yog cov khoom siv sib cais siv los tsav RS-232, Microdrive, thiab network serial tsheb npav.Sinclair ULA muaj npe nrov rau overheating thiab nws tus kheej-ua noj, uas yog hom yooj yim tshaj plaws.Lub interface ntawm no tsis tuaj yeem siv ntau dhau, vim tias nws tsis muaj ULA radiator ntsia, thiab tsis muaj qhov ntsuas kub ntawm lossis ib puag ncig lub plhaub.
Cov kab lus kawg ntawm kev tshem tawm yuav tsum yog phau ntawv qhia, uas yog ib qho zoo sau nyias ntim uas tuaj yeem muab kev nkag siab tob txog qhov system thiab yuav ua li cas nws tau muab tso rau hauv BASIC tus neeg txhais lus.Lub peev xwm sib txuas lus tshwj xeeb yog qhov txaus nyiam vim nws tsis tshua siv.Nws tso siab rau txhua qhov Spectrum hauv lub network los tshaj tawm cov lus txib kom muab tus lej rau nws tus kheej thaum nws pib, vim tias tsis muaj Flash lossis lub cim xeeb zoo sib xws onboard.Qhov no yog thawj zaug npaj los tso lub tsev kawm ntawv kev lag luam ua tus neeg sib tw rau Acorn's Econet, yog li nws tsis yog qhov xav tsis thoob tias BBC Micro yeej ib daim ntawv cog lus hauv tsev kawm ntawv uas tsoomfwv txhawb nqa los ntawm lub tshuab Sinclair.
Pib xyoo 2020, saib rov qab los ntawm qhov tsis nco qab txog kev siv thev naus laus zis no thiab saib lub ntiaj teb uas 100 kB qhov nruab nrab khaws cia hauv li 8 vib nas this es tsis txhob siv ob peb feeb ntawm daim kab xev.Dab tsi yog qhov tsis meej pem yog tias Interface 1 tsis suav nrog lub tshuab luam ntawv sib txuas, vim tias saib ntawm qhov ua tiav Spectrum system, nws tsis yooj yim pom tias nws tau dhau los ua cov khoom siv hluav taws xob hauv tsev txaus hnub no, suav nrog nws cov nqi.Sinclair muag lawv tus kheej lub tshuab luam ntawv thermal, tab sis txawm tias feem ntau cov hnub qub-studded Sinclair enthusiasts tsis tuaj yeem hu rau ZX tshuab luam ntawv lub tshuab luam ntawv tshiab.
Qhov tseeb yog tias, zoo li txhua tus Sinclairs, nws yog tus neeg raug tsim txom ntawm Sir Clive tus nqi txo qis thiab muaj peev xwm ua tau zoo los tsim kev tsis txaus ntseeg los ntawm cov khoom npaj txhij txog.Microdrive tau tsim nyob hauv tsev los ntawm Sinclair, tab sis tej zaum nws tsawg dhau, tsis ntseeg siab, thiab lig dhau lawm.Thawj Apple Macintosh nruab nrog lub tshuab floppy tuaj tawm thaum ntxov 1984 raws li cov khoom lag luam niaj hnub ntawm ZX Microdrive.Txawm hais tias cov kab xev me me no nkag mus rau Sinclair qhov tsis zoo 16-ntsis tshuab QL, nws tau dhau los ua kev lag luam tsis ua haujlwm.Thaum lawv yuav Sinclair cov cuab tam, Amstrad yuav tshaj tawm Spectrum nrog 3-nti floppy disk, tab sis lub sijhawm ntawd Sinclair microcomputers tsuas yog muag raws li kev ua si consoles.Qhov no yog ib qho nthuav dismantling, tab sis tej zaum nws yog qhov zoo tshaj los tawm nrog kev zoo siab nco txog xyoo 1984.
Kuv ua tsaug ntau rau Claire rau kev siv cov khoom siv ntawm no.Nyob rau hauv rooj plaub koj xav tsis thoob, daim duab saum toj no qhia txog ntau yam sib txawv, suav nrog cov khoom ua haujlwm thiab cov khoom tsis ua haujlwm, tshwj xeeb tshaj yog cov khoom siv Microdrive uas tau muab tshem tawm tag yog ib chav ua tsis tiav.Peb tsis xav ua phem rau cov khoom siv rov qab siv computer tsis tsim nyog ntawm Hackaday.
Kuv tau siv Sinclair QL rau ntau tshaj xya xyoo, thiab kuv yuav tsum hais tias lawv cov microdrives tsis yooj yim li cov neeg hais.Kuv feem ntau siv lawv rau tsev kawm ntawv ua homework, thiab lwm yam, thiab yeej tsis nco cov ntaub ntawv.Tab sis muaj tseeb muaj qee qhov "niaj hnub" cov khoom siv uas ntseeg tau ntau dua li cov thawj coj.
Hais txog Interface I, nws txawv heev hauv kev tsim hluav taws xob.Qhov chaw nres nkoj serial tsuas yog qib adapter, thiab RS-232 raws tu qauv yog siv los ntawm software.Qhov no ua rau muaj teeb meem thaum tau txais cov ntaub ntawv, vim tias lub tshuab tsuas muaj sijhawm rau qhov nres me ntsis ua txhua yam nws xav tau ua nrog cov ntaub ntawv.
Tsis tas li ntawd, kev nyeem ntawv los ntawm daim kab xev yog qhov nthuav: koj muaj IO chaw nres nkoj, tab sis yog tias koj nyeem los ntawm nws, interface kuv yuav nres lub processor kom txog thaum tag nrho byte tau nyeem los ntawm daim kab xev (uas txhais tau hais tias yog tias koj tsis nco qab tig rau daim kab xev lub cev muaj zog. thiab lub computer yuav dai).Qhov no tso cai rau synchronization yooj yim ntawm cov processor thiab cov kab xev, uas yog qhov tsim nyog vim tias nkag mus rau qhov thib ob 16K nco thaiv (thawj muaj ROM, qhov thib peb thiab thib plaub muaj kev nco ntxiv ntawm 48K qauv), thiab vim tias microdrive tsis tuaj yeem tshwm sim. yuav tsum nyob rau hauv cheeb tsam ntawd, yog li nws yog tsis yooj yim sua kom siv sij hawm xwb loops.Yog tias Sinclair siv txoj kev nkag tau zoo ib yam li ib qho siv hauv Inves Spectrum (uas tso cai rau ob qho tib si video Circuit Court thiab cov processor kom nkag mus rau video RAM nrog kev tsis txaus siab, ib yam li [ hauv Apple, ces lub interface Circuit Court yuav yooj yim ntau.
Spectrum muaj sijhawm ntau npaum li qhov ua tau los ua cov ntawv tau txais, muab cov cuab yeej ntawm lwm qhov kawg kom raug siv kho vajtse ntws tswj (rau qee qhov (tag nrho?) motherboard "SuperIO" chips * tsis * qhov xwm txheej. Kuv nkim ob peb hnub ntawm debugging ua ntej paub qhov no thiab hloov mus rau lub qub qub USB serial adapter, Kuv xav tsis thoob tias Just Worked ua haujlwm thawj zaug)
Hais txog RS232.Kuv tau txais 115k kev kho qhov yuam kev thiab 57k txhim khu kev qha me ntsis tsis muaj qhov yuam kev kho raws tu qauv.Qhov zais cia yog txuas ntxiv lees txais mus txog 16 bytes tom qab pov tseg CTS.Tus thawj ROM code tsis ua qhov no, thiab tsis tuaj yeem sib txuas lus nrog UART "niaj hnub".
Wikipedia hais tias 120 kbit / sec.Hais txog cov txheej txheem tshwj xeeb, kuv tsis paub, tab sis kuv paub tias nws siv lub tso suab paj nruag lub taub hau, thiab kev cia me ntsis yog "unaligned".Kuv tsis paub yuav piav li cas ua lus Askiv… cov khoom hauv ib txoj kev pib hauv nruab nrab ntawm cov khoom hauv lwm txoj kev.
Tab sis kev tshawb nrhiav ceev kuv pom nplooj ntawv no, qhov twg tus neeg siv txuas lub oscilloscope rau cov ntaub ntawv teeb liab, thiab nws zoo li FM modulation.Tab sis nws yog QL thiab tsis sib xws nrog Spectrum.
Yog lawm, tab sis thov nco ntsoov tias qhov txuas hais txog Sinclair QL microdrives: txawm hais tias lawv lub cev zoo ib yam, lawv siv cov ntawv tsis sib xws, yog li QL tsis tuaj yeem nyeem Spectrum hom tapes, thiab rov ua dua.
ntsis aligned.Cov bytes yog interleaved ntawm kab 1 thiab kab 2. Nws yog bi-theem encoding.Ib fm feem ntau pom ntawm daim npav rho nyiaj.Lub interface reassembles cov bytes hauv hardware, thiab lub computer tsuas nyeem cov bytes.Tus thawj cov ntaub ntawv tus nqi yog 80kbps ib txoj kev los yog 160kbps rau ob qho tib si.Qhov kev ua tau zoo zoo ib yam li floppy disks ntawm lub sijhawm ntawd.
Kuv tsis paub, tab sis muaj ob peb tsab xov xwm hais txog cov ntaub ntawv sau tseg thaum lub sijhawm.Txhawm rau siv lub tshuab kaw lus uas twb muaj lawm, cov suab nrov yuav tsum tau ua.Tab sis yog tias koj hloov kho lub taub hau daim kab xev ncaj qha, koj tuaj yeem pub lawv ncaj qha nrog DC lub zog thiab txuas ncaj qha rau Schmitt trigger rau playback.Yog li nws tsuas yog pub cov teeb liab serial ntawm daim kab xev taub hau.Koj tuaj yeem tau txais kev nrawm dua yam tsis muaj kev txhawj xeeb txog qib kev ua si.
Nws yog tiag tiag siv nyob rau hauv lub "mainframe" ntiaj teb no.Kuv ib txwm xav tias nws yog siv hauv qee qhov khoos phis tawj me me, xws li "floppy disks", tab sis kuv tsis paub.
Kuv muaj QL nrog 2 micro-drives, uas yog qhov tseeb, tsawg kawg QL muaj kev ntseeg siab dua li cov neeg hais.Kuv muaj ZX Spectrum, tab sis tsis muaj microdrives (txawm tias kuv xav tau lawv).Qhov tsis ntev los no kuv tau txais yog ua qee qhov kev txhim kho hla.Kuv siv QL ua cov ntawv nyeem thiab hloov cov ntaub ntawv mus rau Spectrum uas sib sau cov ntaub ntawv ntawm serial (Kuv tabtom sau lub tshuab luam ntawv tsav tsheb rau ZX Spectrum PCB Designer program, uas yuav hloov kho thiab Ntxig pixels rau qhov kev daws teeb meem ntawm 216ppi kom tsis txhob khiav. tshwm jagged).
Kuv nyiam kuv QL thiab nws cov software bundled, tab sis kuv yuav tsum ntxub nws microdrive.Kuv feem ntau tau txais qhov ua yuam kev "YOG LUB MEDIUM" tom qab tawm haujlwm.Kev ntxhov siab thiab tsis ntseeg.
Kuv sau kuv daim ntawv tshawb fawb hauv computer BSc ntawm kuv 128Kb QL.Quill tsuas khaws cia txog 4 nplooj ntawv xwb.Kuv yeej tsis twv kom dhau lub ram vim nws yuav pib tuav lub micro tsav thiab qhov yuam kev yuav tshwm sim sai sai.
Kuv tau txhawj xeeb heev txog kev ntseeg tau ntawm Microdrive uas kuv tsis tuaj yeem rov qab txhua qhov kev kho kho ntawm ob daim kab xev Microdrive.Txawm li cas los xij, tom qab sau ntawv rau ib hnub, kuv tau khaws kuv tshooj tshiab nyob rau hauv lub npe ntawm tshooj qub, yog li sau kuv cov hauj lwm hnub ua ntej.
"Kuv xav tias nws tsis ua li cas, yam tsawg kawg kuv muaj ib tug thaub qab!";Tom qab hloov daim kab xev, kuv nco qab tias hnub no txoj haujlwm yuav tsum tau txais kev cawmdim ntawm qhov thaub qab thiab sau dua hnub dhau los ua haujlwm raws sijhawm!
Kuv tseem muaj kuv QL, kwv yees li ib xyoos dhau los, kuv tau ua tiav siv 30-35 xyoo mini drive cartridge kom txuag thiab thauj khoom.
Kuv siv lub floppy drive ntawm ibm pc, nws yog ib tug adapter nyob rau sab nraum qab ntawm lub spectrum, nws yog heev ceev thiab lom zem.(Piv nws nrog daim kab xev hnub thiab hmo ntuj)
Qhov no coj kuv rov qab los.Thaum ntawd kuv hacked txhua yam.Nws coj kuv ib lub lim tiam los nruab Elite ntawm Microdrive thiab cia LensLok ib txwm ua lub luag haujlwm AA.Lub sijhawm thauj neeg tseem ceeb yog 9 vib nas this.Siv sijhawm ntau tshaj li ib feeb ntawm Amiga!Nws yog ib qho kev nco pov tseg.Kuv siv qhov kev cuam tshuam niaj hnub los saib xyuas int 31(?) rau Kempston joystick hluav taws.LensLok siv kev cuam tshuam rau cov lus nkag rau cov keyboard, yog li kuv tsuas yog xav tau nyem rau hauv cov lej kom nws tau txais kev xiam oob qhab.Cov neeg tseem ceeb tsuas tshuav txog 200 bytes tsis siv.Thaum kuv tau txais kev cawmdim nrog * "m", 1, daim duab duab ntxoov ntxoo ntawm interface 1 nqos kuv cuam tshuam!Wow.36 xyoo dhau los.
Kuv khib me ntsis… Kuv muaj Discovery Opus 1 3.5-nti floppy disk ntawm kuv Speccy.Kuv pom tias ua tsaug rau kev sib tsoo zoo siab rau hnub uas cov neeg tseem ceeb poob thaum thauj khoom, Kuv tuaj yeem txuag cov neeg tseem ceeb rau lub floppy disk… thiab nws yog 128 version, tsis muaj lub lens xauv!tshwm sim!
Nws yog qhov nthuav tias kwv yees li 40 xyoo tom qab, lub floppy disk tuag thiab daim kab xev tseem muaj :) PS: Kuv siv lub tsev qiv ntawv daim kab xev, txhua tus muaj 18 tsav, txhua tsav tuaj yeem muab 350 MB / s ceev;)
Kuv xav paub yog tias koj disassemble lub cassette adapter, koj puas tuaj yeem siv lub taub hau sib nqus los thauj cov ntaub ntawv mus rau hauv lub computer ntawm microdrive?
Lub taub hau zoo sib xws, yog tias tsis zoo ib yam (tab sis "lub taub hau eraser" yuav tsum tau muab tso rau hauv cov schematic), tab sis daim kab xev hauv microdrive yog nqaim dua, yog li koj yuav tsum tsim daim kab xev tshiab.
"Tsuas yog cov neeg nplua nuj heev tuaj yeem them taus disks."Tej zaum hauv UK, tab sis yuav luag txhua tus neeg hauv Asmeskas muaj lawv.
Kuv nco qab tus nqi ntawm PlusD + disk drive + fais fab adapter, nyob rau hauv 1990, yog hais txog 33.900 pesetas (kwv yees 203 euros).Nrog kev nce nqi, tam sim no yog 433 Euros (512 USD).Qhov no yog roughly tib yam li tus nqi ntawm ib lub computer tiav.
Kuv nco qab tias xyoo 1984, tus nqi ntawm C64 yog US $ 200, thaum tus nqi ntawm 1541 yog US $ 230 (qhov tseeb siab dua lub computer, tab sis xav tias nws muaj nws tus kheej 6502, qhov no tsis yog qhov xav tsis thoob).Ob qho no ntxiv rau lub TV pheej yig tseem tsawg dua ib feem peb ntawm tus nqi ntawm Apple II.Ib lub thawv ntawm 10 floppy disks muag rau $ 15, tab sis tus nqi tau poob ntau xyoo.
Ua ntej kuv so haujlwm, kuv tau siv lub tuam txhab tsim thiab tsim khoom zoo heev nyob rau sab qaum teb ntawm Cambridge (UK), uas tsim txhua lub tshuab siv los tsim Microdrives cartridges.
Kuv xav tias thaum xyoo 1980s, qhov tsis muaj qhov chaw sib txuas sib txuas nrog centronics tsis yog qhov loj, thiab cov tshuab luam ntawv serial tseem muaj ntau.Dhau li ntawd, txiv ntxawm Clive xav muag koj ZX FireHazard…zoo tshuab luam ntawv.Qhov kawg hum thiab tsis hnov tsw ntawm ozone thaum nws txav mus rau hauv daim ntawv nyiaj-plated.
Micro drives, kuv hmoov phem heev, kuv muaj siab rau lawv thaum lawv tawm los, tab sis tsis txog li ob peb xyoos tom qab ntawd kuv tau pib khaws qee cov khoom siv pheej yig los ntawm cov khoom siv thib ob, thiab kuv tsis tau tau tej hardware.Kuv xaus nrog 2 qhov chaw nres nkoj 1, 6 micro-drives, qee lub tsheb siv randomly, thiab ib lub thawv ntawm 30 lub tsheb tshiab 3rd square, yog tias kuv tuaj yeem ua ib qho ntawm lawv hauv ib qho 2 × 6 ua ke Kuv ntxhov siab heev thaum kuv ua haujlwm hauv ib qhov chaw.Feem ntau, lawv zoo li tsis tau formatted.Tsis txhob xav txog nws, txawm tias kuv tau txais kev pab los ntawm pawg xov xwm thaum kuv mus online thaum ntxov 90s.Txawm li cas los xij, tam sim no kuv muaj "tiag tiag" khoos phis tawj, kuv tau txais cov chaw nres nkoj serial mus ua haujlwm, yog li kuv tau khaws cov khoom rau lawv ntawm null modem cable thiab khiav qee qhov tsis paub meej terminals.
Puas muaj leej twg sau ib qho kev pab cuam rau "pre-stretch" tapes los ntawm kev khiav lawv hauv lub voj ua ntej sim ua lawv?
Kuv tsis muaj micro tsav, tab sis kuv nco qab nyeem nws hauv ZX Magazine (Spain).Thaum kuv nyeem nws, ua rau kuv xav tsis thoob!
Kuv zoo li nco ntsoov tias lub tshuab luam ntawv yog electrostatic, tsis thermal... Kuv yuav ua yuam kev.Tus neeg uas kuv tau ua haujlwm tsim kho software hauv 80s lig tau ntsaws ib daim kab xev rau hauv Speccy thiab ntsaws EPROM programmer rau hauv qhov chaw nres nkoj tom qab.Yuav hais tias qhov no yog ib tug bastard siv yuav yog ib tug understatement.
Tsis yog.Daim ntawv yog coated nrog ib txheej nyias ntawm cov hlau, thiab lub tshuab luam ntawv rub cov hlau stylus hla.Lub siab voltage mem tes yog tsim los ablate cov hlau txheej nyob qhov twg cov pixels dub xav tau.
Thaum koj tseem hluas, ZX interface 1 nrog RS-232 interface ua rau koj zoo li "tus huab tais ntawm lub ntiaj teb".
Qhov tseeb, Microdrives tau tshaj kuv cov peev nyiaj (yam tsawg kawg nkaus).Ua ntej kuv ntsib tus txiv neej no uas muag pirated games LOL, tsis muaj leej twg kuv paub.Hauv kev pom, Kuv yuav tsum yuav Interface 1 thiab qee qhov ROM ua si.Tsawg heev li tus qaib cov hniav.
