Kwa anthu ambiri omwe ankagwiritsa ntchito makompyuta apanyumba a 8-bit kumayambiriro kwa zaka za m'ma 1980, kugwiritsa ntchito matepi a makaseti kusunga mapulogalamu kunali kukumbukira kosatha.Ndi anthu olemera kwambiri okha omwe angakwanitse kugula ma drive a disk, kotero ngati simukukonda lingaliro lodikirira kuti codeyo ikhale yosatha, ndiye kuti mwasowa mwayi.Komabe, ngati muli ndi Sinclair Spectrum, ndiye pofika 1983, muli ndi njira ina, Sinclair ZX Microdrive yapadera.
Ili ndi mawonekedwe opangidwa mkati ndi Sinclair Research.Ndi mtundu wa miniaturized wa ngolo yosatha ya tepi ya loop.Yakhala ngati kaseti ya Hi-Fi ya 8-track pazaka khumi zapitazi ndipo imalonjeza nthawi yotsegula mwachangu.Masekondi ndi kusungirako kwakukulu kopitilira 80 kB.Eni ake a Sinclair amatha kuyenderana ndi anyamata akuluakulu m'dziko la makompyuta apanyumba, ndipo akhoza kutero popanda kuswa banki kwambiri.
Monga wapaulendo wobwera kuchokera ku msasa wa owononga kumtunda, chifukwa cha mliriwu, boma la Britain linafuna kuti ndikhale ndekha kwa milungu iwiri.Ndinachita monga mlendo wa Claire.Claire ndi bwenzi langa ndipo amakhala gwero la chidziwitso.Prolific 8-bit Sinclair hardware ndi mapulogalamu osonkhanitsa.Pocheza za Microdrive, sanangogula zitsanzo za ma drive ndi mapulogalamu, komanso mawonekedwe a mawonekedwe ndi zida zoyambira za Microdrive.Izi zinandipatsa mwayi woti ndiyang'ane ndikuchotsa dongosololi ndikupatsa owerenga zidziwitso zochititsa chidwi pa chipangizo chachilendo ichi.
Tengani Microdrive.Ndi gawo lomwe limalemera pafupifupi 80 mm x 90 mm x 50 mm ndipo limalemera zosakwana 200 magalamu.Imatsatira masitayelo omwewo a Rich Dickinson monga makiyi oyambira a rabara Spectrum.Kutsogolo kuli kutseguka kwa pafupifupi 32 mm x 7 mm pakuyika makatiriji a tepi a Microdrive, ndipo mbali iliyonse ya kumbuyo kuli cholumikizira m'mphepete mwa njira 14 cha PCB cholumikizira ku Spectrum ndi daisy-chaining kudzera mu basi yamtundu wina wa Microdrive. imapereka zingwe za riboni ndi zolumikizira.Mpaka ma drive asanu ndi atatu amatha kulumikizidwa motere.
Pankhani ya mitengo kumayambiriro kwa zaka za m'ma 1980, Spectrum inali makina owopsa, koma mtengo wa kukhazikitsa kwake unali woti unkalipira pang'ono kwambiri pa mawonekedwe a hardware omwe anamangidwa kupyola ma doko ake a kanema ndi makaseti.Kumbuyo kwake kuli cholumikizira cham'mphepete, chomwe chimawulula mabasi osiyanasiyana a Z80, ndikusiya njira zina zolumikizirana kudzera mu gawo lokulitsa.Mwiniwake wa Spectrum akhoza kukhala ndi adaputala ya Kempston yosangalatsa motere, chitsanzo chodziwikiratu.Spectrum ilibe cholumikizira cha Microdrive, kotero Microdrive ili ndi mawonekedwe ake.Sinclair ZX Interface 1 ndi gawo lokhala ngati mphero lomwe limalumikizana ndi cholumikizira m'mphepete pa Spectrum ndikumangirira pansi pa kompyuta.Imapereka mawonekedwe a Microdrive, doko la RS-232 siriyo, cholumikizira chosavuta cha LAN chogwiritsa ntchito jack 3.5 mm, ndi Replica of Sinclair edge cholumikizira chokhala ndi zolumikizira zambiri zoyikidwa.Mawonekedwewa ali ndi ROM yomwe imadzipanga yokha ku Spectrum's ROM yamkati, monga tidanenera pamene prototype Spectrum idawonekera ku Cambridge Computing History Center, monga tonse tikudziwa, sinamalizidwe ndipo ntchito zake zina zomwe zikuyembekezeka sizinakwaniritsidwe.
Ndizosangalatsa kulankhula za hardware, koma ndithudi, iyi ndi Hackaday.Simumangofuna kuziwona, mukufuna kuwona momwe zimagwirira ntchito.Tsopano ndi nthawi yoti tisokoneze, titsegule kaye gawo la Microdrive lokha.Monga Spectrum, pamwamba pa chipangizocho chimakutidwa ndi mbale yakuda ya aluminiyamu yokhala ndi chizindikiro cha Spectrum, chomwe chiyenera kupatulidwa mosamala ndi zotsalira za 1980s zomatira kuti ziwonetsere zomangira ziwiri zomwe zimateteza kumtunda.Monga Spectrum, ndizovuta kuchita izi popanda kupindika aluminiyamu, kotero maluso ena amafunikira.
Kwezani gawo lakumtunda ndikumasula woyendetsa LED, chipangizo cha makina ndi bolodi lozungulira zikuwonekera m'munda wa masomphenya.Owerenga odziwa nthawi yomweyo amawona kufanana komwe kulipo pakati pake ndi kaseti yayikulu ya 8-track audio.Ngakhale izi sizimachokera ku dongosololi, zimagwira ntchito mofananamo.Njira yokhayo ndiyosavuta.Kumanja kuli chosinthira chaching'ono chomwe chimamva tepiyo ikachotsa chizindikiro choteteza, ndipo kumanzere kuli shaft yamoto yokhala ndi capstan roller.Pamapeto a bizinesi ya tepiyo pali mutu wa tepi, womwe umawoneka wofanana kwambiri ndi zomwe mungapeze mu chojambulira cha makaseti, koma uli ndi kalozera wocheperako.
Pali ma PCB awiri.Kumbuyo kwa mutu wa tepi ndi 24-pini mwambo ULA (Uncommitted Logic Array, makamaka wotsogola wa CPLD ndi FPGA mu 1970s) posankha ndi kuyendetsa ma drive.Zina zimalumikizidwa Kumunsi kwa theka la nyumba yomwe imakhala ndi zolumikizira ziwiri zolumikizirana ndi magetsi osinthira magalimoto.
Tepiyo ndi 43 mm × 7 mm × 30 mm ndipo imakhala ndi tepi yodzipangira yokhayokha yokhazikika yokhala ndi kutalika kwa mita 5 ndi kutalika kwa 1.9 mm.Sindimuimba mlandu Claire chifukwa chosandilola kuti nditsegule imodzi mwa makatiriji ake akale, koma mwamwayi, Wikipedia inatipatsa chithunzi cha katiriji yomwe ili pamwamba yotsekedwa.Zofanana ndi tepi ya 8-track zimawonekera nthawi yomweyo.Capstan ikhoza kukhala mbali imodzi, koma tepi yofananayo imabwezeretsedwa pakati pa reel imodzi.
Buku la ZX microdrive likunena motsimikiza kuti kaseti iliyonse imatha kukhala ndi 100 kB ya data, koma zoona zake ndizakuti zowonjezera zina zikagwiritsidwa ntchito, zimatha kusunga pafupifupi 85 kB ndikupitilira kupitilira 90 kB.Nkoyenera kunena kuti iwo sali ofalitsa odalirika kwambiri, ndipo matepi potsirizira pake anatambasulidwa kufikira pamene sanathe kuŵerengedwanso.Ngakhale Buku la Sinclair limalimbikitsa kuthandizira matepi omwe amagwiritsidwa ntchito kwambiri.
Chigawo chomaliza cha dongosolo kuti disassembled ndi mawonekedwe 1 palokha.Mosiyana ndi mankhwala a Sinclair, alibe zomangira zobisika pansi pa mapazi a mphira, kotero kuwonjezera pa ntchito yochenjera yolekanitsa pamwamba pa nyumba kuchokera ku Spectrum edge connector, ndizosavuta kusokoneza.Mkati mwake muli tchipisi zitatu, Texas Instruments ROM, chida chapadziko lonse ULA m'malo mwa pulojekiti ya Ferranti yomwe imagwiritsidwa ntchito ndi Spectrum palokha, ndi malingaliro pang'ono a 74.ULA imaphatikizanso mabwalo onse kupatula zida zomwe zimagwiritsidwa ntchito poyendetsa RS-232, Microdrive, ndi ma serial mabasi.Sinclair ULA ndi yodziwika bwino chifukwa cha kutentha kwambiri komanso kudziphika, womwe ndi mtundu womwe uli pachiwopsezo kwambiri.Mawonekedwe apa sangathe kugwiritsidwa ntchito mochuluka, chifukwa alibe radiator ya ULA yoikidwa, ndipo palibe chizindikiro cha kutentha pa chipolopolo kapena kuzungulira.
Chiganizo chomaliza cha disassembly chiyenera kukhala bukhuli, lomwe ndi voliyumu yopyapyala yolembedwa bwino yomwe ingapereke kumvetsetsa mozama za dongosololi ndi momwe likugwirizanirana ndi womasulira wa BASIC.Kuthekera kwa maukonde ndikosangalatsa kwambiri chifukwa sikumagwiritsidwa ntchito kawirikawiri.Imadalira Spectrum iliyonse pamaneti kuti ipereke lamulo lodzipatsa nambala ikayamba, chifukwa palibe Flash kapena kukumbukira kofananako.Izi zidapangidwa poyambilira kuti msika wapasukulu ukhale wopikisana ndi Acorn's Econet, kotero sizodabwitsa kuti BBC Micro idapambana kontrakitala yothandizidwa ndi boma m'malo mwa makina a Sinclair.
Kuyambira mu 2020, yang'anani mmbuyo paukadaulo wapakompyuta woyiwalikawu ndikuyang'ana dziko lomwe 100 kB yosungirako sing'anga imadzaza pafupifupi masekondi 8 m'malo mwa mphindi zochepa zotsitsa tepi.Chomwe chimasokoneza ndikuti Interface 1 sichimaphatikizapo mawonekedwe osindikizira ofanana, chifukwa poyang'ana dongosolo lonse la Spectrum, sizili zovuta kuona kuti yakhala makompyuta okwanira ogwira ntchito kunyumba, kuphatikizapo mtengo wake.Sinclair amagulitsa makina awo osindikizira otentha, koma ngakhale okonda nyenyezi kwambiri a Sinclair sangatchule chosindikizira cha ZX kuti ndi chosindikizira chachilendo.
Chowonadi ndichakuti, monga onse a Sinclairs, anali wovutitsidwa ndi kuchepetsedwa kwa mtengo kwa Sir Clive komanso luso lanzeru lopanga luntha losatheka kuchokera kuzinthu zosayembekezereka.Microdrive idapangidwa kwathunthu mnyumba ndi Sinclair, koma mwina inali yaying'ono, yosadalirika, komanso mochedwa kwambiri.Apple Macintosh yoyamba yokhala ndi floppy drive idatuluka koyambirira kwa 1984 ngati chinthu chamakono cha ZX Microdrive.Ngakhale matepi ang'onoang'onowa adalowa mu makina a 16-bit a Sinclair a QL, zidakhala zolephera pamalonda.Atangogula katundu wa Sinclair, Amstrad idzayambitsa Spectrum ndi 3-inch floppy disk, koma panthawiyo Sinclair microcomputers ankangogulitsidwa ngati masewera a masewera.Uku ndikugwetsa kosangalatsa, koma mwina ndibwino kuchoka ndi kukumbukira kosangalatsa kwa 1984.
Ndine woyamikira kwambiri kwa Claire chifukwa chogwiritsa ntchito hardware pano.Ngati mukudabwa, chithunzi pamwambapa chikuwonetsa magawo osiyanasiyana, kuphatikiza zida zogwirira ntchito komanso zosagwira ntchito, makamaka gawo losakanizidwa la Microdrive ndi gawo lolephera.Sitikufuna kuwononga zida zam'mbuyo zam'manja mosafunikira pa Hackaday.
Ndagwiritsa ntchito Sinclair QL kwa zaka zoposa zisanu ndi ziwiri, ndipo ndiyenera kunena kuti ma microdrive awo sali ofooka monga momwe anthu amanenera.Nthawi zambiri ndimagwiritsa ntchito homuweki yakusukulu, ndi zina zambiri, ndipo sindiphonya zikalata zilizonse.Koma palidi zida "zamakono" zomwe ndizodalirika kwambiri kuposa zoyambirira.
Ponena za Interface I, ndizodabwitsa kwambiri pamapangidwe amagetsi.Doko la serial ndi adapter yokhayo, ndipo protocol ya RS-232 imayendetsedwa ndi mapulogalamu.Izi zimabweretsa mavuto polandira deta, chifukwa makinawo amakhala ndi nthawi yokhayo yoyimitsa kuti achite chilichonse chomwe chiyenera kuchita ndi deta.
Kuphatikiza apo, kuwerenga kuchokera pa tepi ndikosangalatsa: muli ndi doko la IO, koma ngati muwerenga kuchokera pamenepo, mawonekedwe ndikuyimitsa purosesa mpaka zonse zitawerengedwa kuchokera pa tepi (zomwe zikutanthauza kuti ngati muiwala Yatsani mota ya tepi. ndipo kompyuta idzakhazikika).Izi zimalola kulumikizana kosavuta kwa purosesa ndi tepi, zomwe ndizofunikira chifukwa chofikira pachikumbutso chachiwiri cha 16K (yoyamba ili ndi ROM, yachitatu ndi yachinayi imakhala ndi kukumbukira kowonjezera kwamitundu ya 48K), ndipo chifukwa cha buffer ya microdrive Imachitika. kukhala m'derali, kotero ndizosatheka kugwiritsa ntchito malupu okhazikika nthawi.Ngati Sinclair amagwiritsa ntchito njira yolowera ngati yomwe imagwiritsidwa ntchito mu Inves Spectrum (yomwe imalola kuti mavidiyo ndi purosesa azitha kupeza RAM ya kanema popanda chilango, monga [mu Apple, ndiye kuti mawonekedwe ozungulira akanakhala ophweka Kwambiri.
Spectrum ili ndi nthawi yochuluka yotheka yokonza ma byte olandilidwa, malinga ngati chipangizo kumbali ina chikugwiritsa ntchito bwino kayendedwe ka hardware (kwa ena (onse?) tchipisi ta "SuperIO" * osati * momwe zinthu zilili. kuchotsa zolakwika ndisanazindikire izi ndikusinthira ku adapter yakale ya USB, ndidadabwa kuti Just Worked inagwira ntchito koyamba)
Pafupifupi RS232.Ndidakonza zolakwika za 115k ndi kugunda kwa 57k kodalirika popanda kuwongolera zolakwika.Chinsinsi ndikupitiriza kuvomereza mpaka 16 byte mutataya CTS.Khodi yapachiyambi ya ROM sinachite izi, kapena kuyankhulana ndi UART "wamakono".
Wikipedia imati 120 kbit / sec.Ponena za ndondomeko yeniyeni, sindikudziwa, koma ndikudziwa kuti imagwiritsa ntchito mutu wa tepi ya stereo, ndipo kusungirako pang'ono ndi "kusagwirizana".Sindikudziwa momwe ndingafotokozere m'Chingerezi… tinthu tating'onoting'ono ta njanji imodzi timayambira pakati pa tinthu tambiri tambiri.
Koma kufufuza mwamsanga ndinapeza tsamba ili, pomwe wogwiritsa ntchito amagwirizanitsa oscilloscope ndi chizindikiro cha deta, ndipo zikuwoneka ngati kusintha kwa FM.Koma ndi QL ndipo sigwirizana ndi Spectrum.
Inde, koma chonde kumbukirani kuti ulalowu ukunena za Sinclair QL ma microdrive: ngakhale ali ofanana, amagwiritsa ntchito mawonekedwe osagwirizana, kotero QL siyingawerenge matepi amtundu wa Spectrum, ndi mosemphanitsa.
Zogwirizana pang'ono.Ma byte amalumikizidwa pakati pa track 1 ndi track 2. Ndi ma encoding a bi-phase.Ma fm omwe amapezeka kwambiri pama kirediti kadi.Mawonekedwewa amaphatikizanso ma byte mu hardware, ndipo kompyuta imawerenga ma byte okha.The original deta mlingo ndi 80kbps pa njanji kapena 160kbps onse.Kuchita kwake kuli kofanana ndi ma floppy disks a nthawi imeneyo.
Sindikudziwa, koma panali nkhani zingapo zojambulira zodzaza panthawiyo.Kuti mugwiritse ntchito chojambulira chamakaseti chomwe chilipo, mawu omvera amafunikira.Koma ngati musintha mutu wa tepi wolowera mwachindunji, mutha kuwadyetsa mwachindunji ndi mphamvu ya DC ndikulumikiza mwachindunji choyambitsa cha Schmitt kuti musewere.Chifukwa chake zimangodyetsa chizindikiro chamutu wa tepi.Mutha kuthamanga mwachangu popanda kudandaula za kuchuluka kwamasewera.
Izo ndithudi ntchito mu "mainframe" dziko.Nthawi zonse ndimaganiza kuti amagwiritsidwa ntchito m'mapulogalamu ang'onoang'ono apakompyuta, monga "floppy disks", koma sindikudziwa.
Ndili ndi QL yokhala ndi 2 micro-drive, zomwe ndi zoona, osachepera QL ndiyodalirika kuposa momwe anthu amanenera.Ndili ndi ZX Spectrum, koma palibe ma microdrive (ngakhale ndikuwafuna).Chinthu chaposachedwa kwambiri chomwe ndapeza ndikuchita zina zowonjezera.Ndimagwiritsa ntchito QL ngati mkonzi wa zolemba ndikusamutsa mafayilo ku Spectrum yomwe imasonkhanitsa mafayilo kudzera mu seriyo (ndikulemba chosindikizira cha pulogalamu ya ZX Spectrum PCB Designer, yomwe idzakweza ndi Ikani ma pixel ku chigamulo cha 216ppi kuti nyimboyo isasinthe. kuwoneka wakuda).
Ndimakonda QL yanga ndi mapulogalamu ake odzaza mitolo, koma ndiyenera kudana ndi microdrive yake.Nthawi zambiri ndimalandira zolakwika za "BAD OR CHANGED MEDIUM" ndikatuluka kuntchito.Zokhumudwitsa komanso zosadalirika.
Ndinalemba pepala langa la sayansi ya kompyuta BSc pa 128Kb QL yanga.Quill imatha kusunga masamba pafupifupi 4 okha.Sindinayerekeze konse kusefukira nkhosayo chifukwa imayamba kugwedeza ma micro drive ndipo cholakwikacho chimatuluka posachedwa.
Ndakhala ndi nkhawa kwambiri ndi kudalirika kwa Microdrive kotero kuti sindingathe kuthandizira gawo lililonse lokonzekera pa matepi awiri a Microdrive.Komabe, nditalemba kwa tsiku lathunthu, ndinasunga mwangozi mutu wanga watsopano pansi pa dzina la mutu wakale, motero ndinalemba ntchito yanga dzulo lake.
"Ndikuganiza kuti zili bwino, osachepera ndili ndi zosunga zobwezeretsera!";Pambuyo kusintha tepi, ndinakumbukira kuti ntchito lero ayenera kupulumutsidwa pa zosunga zobwezeretsera ndi overwrite ntchito tsiku lapita mu nthawi!
Ndidakali ndi QL yanga, pafupifupi chaka chapitacho, ndidagwiritsa ntchito bwino katiriji kakang'ono ka 30-35 kakang'ono kuti ndisunge ndikuyiyika.
Ndidagwiritsa ntchito floppy drive ya ibm pc, ndi adapter kumbuyo kwa sipekitiramu, ndiyothamanga kwambiri komanso yosangalatsa.(fanizirani ndi tepi usana ndi usiku)
Izi zimandibwezeranso.Nthawi imeneyo ndinabera chilichonse.Zinanditengera sabata kuti ndikhazikitse Elite pa Microdrive ndikulola LensLok kukhala gawo la AA nthawi zonse.Nthawi yotsegula osankhika ndi masekondi 9.Ndakhala nthawi yopitilira miniti pa Amiga!Kwenikweni ndi malo otaya kukumbukira.Ndinagwiritsa ntchito chizolowezi chosokoneza kuyang'anira int 31(?) pamoto wa Kempston joystick.LensLok imagwiritsa ntchito zosokoneza polowetsa kiyibodi, chifukwa chake ndikungofunika kufinya khodi kuti ikhale yolephereka.Elite adangosiya pafupifupi ma byte 200 osagwiritsidwa ntchito.Nditasunga ndi *"m",1, mapu azithunzi a mawonekedwe 1 adameza kusokoneza kwanga!Oo.Zaka 36 zapitazo.
Ndinabera pang'ono… Ndili ndi Discovery Opus 1 3.5-inch floppy disk pa Speccy yanga.Ndidapeza kuti chifukwa cha ngozi yosangalatsa patsiku lomwe Elite idagwa ndikutsitsa, nditha kupulumutsa Elite ku floppy disk… ndipo ndi mtundu wa 128, palibe loko!zotsatira!
Ndizosangalatsa kuti pafupifupi zaka 40 pambuyo pake, floppy disk yafa ndipo tepiyo ikadalipo :) PS: Ndimagwiritsa ntchito laibulale ya tepi, iliyonse ili ndi ma drive 18, galimoto iliyonse imatha kupereka liwiro la 350 MB / s;)
Ndikufuna kudziwa ngati mumasula adaputala ya makaseti, kodi mungagwiritse ntchito maginito kuti mulowetse deta mu kompyuta kudzera pa microdrive?
Mituyo ndi yofanana kwambiri, ngati si yofanana (koma "mutu wofufutira" uyenera kuphatikizidwa mu schematic), koma tepi mu microdrive ndi yopapatiza, kotero muyenera kumanga kalozera watsopano wa tepi.
"Ndi anthu olemera kwambiri okha omwe angakwanitse kugula ma drive a disk."Mwina ku UK, koma pafupifupi aliyense ku US ali nawo.
Ndikukumbukira mtengo wa PlusD + disk drive + adapter yamagetsi, mu 1990, inali pafupifupi 33.900 pesetas (pafupifupi 203 euro).Ndi inflation, tsopano ndi 433 Euros (512 USD).Izi ndizofanana ndi mtengo wakompyuta yathunthu.
Ndikukumbukira kuti mu 1984, mtengo wa C64 unali US $ 200, pamene mtengo wa 1541 unali US $ 230 (kwenikweni wapamwamba kuposa kompyuta, koma poganizira kuti ili ndi 6502 yake, izi sizosadabwitsa).Awiriwa kuphatikiza TV yotsika mtengo akadali ochepera kotala la mtengo wa Apple II.Bokosi la ma floppy disks 10 limagulitsidwa $15, koma mtengo watsika m'zaka zapitazi.
Ndisanapume pantchito, ndinagwiritsa ntchito kampani yabwino kwambiri yopangira makina komanso kupanga makina kumpoto kwa Cambridge (UK), yomwe inkapanga makina onse opangira makatiriji a Microdrives.
Ndikuganiza kuti kumayambiriro kwa zaka za m'ma 1980, kusowa kwa doko lofanana logwirizana ndi centronics sikunali vuto lalikulu, ndipo osindikiza osindikizira anali ofala.Kupatula apo, Amalume Clive akufuna kukugulitsani ZX FireHazard…osindikiza bwino.Kung'ung'udza kosalekeza ndi fungo la ozoni pamene ukusunthira pansi pa pepala lokutidwa ndi siliva.
Ma Micro drives, mwayi wanga udali woyipa kwambiri, ndidadzadza ndi chikhumbo chawo atatuluka, koma sizinali mpaka zaka zingapo ndidayamba kunyamula zida zina zotsika mtengo kuchokera kuzinthu zomwe zidagwiritsidwa ntchito kale, ndipo sindinatero. pezani zida zilizonse.Ndidamaliza ndi ma 2 madoko 1, ma 6 ma micro-drive, ngolo zogwiritsidwa ntchito mwachisawawa, ndi bokosi la ngolo 30 zatsopano za 3rd square, ngati nditha kupanga iliyonse mwazophatikiza 2 × 6 ndimakwiyitsidwa kwambiri ndikamagwira ntchito. malo amodzi.Makamaka, iwo samawoneka ngati amapangidwa.Sindinaganizepo za izi, ngakhale nditalandira thandizo kuchokera kumagulu ankhani nditapita pa intaneti koyambirira kwa 90s.Komabe, popeza ndili ndi makompyuta "enieni", ndinapeza ma doko kuti agwire ntchito, kotero ndidawasungira zinthu kudzera pa chingwe cha modem cha null ndikuyendetsa ma terminals osayankhula.
Kodi pali amene adalembapo pulogalamu yoti "atambasule" matepi powayendetsa mulupu musanayese kuwapanga?
Ndilibe kagalimoto kakang'ono, koma ndikukumbukira ndikuwerenga mu ZX Magazine (Spain).Nditaiwerenga, inandidabwitsa!
Ndikuwoneka kuti ndikukumbukira kuti chosindikizira ndi electrostatic, osati kutentha… Mwina ndikulakwitsa.Munthu yemwe ndidagwirapo ntchito yopanga mapulogalamu ophatikizidwa kumapeto kwa 80s adalumikiza imodzi mwama tepi mu Speccy ndikulumikiza pulogalamu ya EPROM padoko lakumbuyo.Kunena kuti uku ndi kugwiritsiridwa ntchito kwachirengedwe kungakhale kunyalanyaza.
Ngakhalenso.Pepalalo limakutidwa ndi chitsulo chopyapyala, ndipo chosindikiziracho chimakokera cholembera chachitsulo.Kuthamanga kwamphamvu kwamagetsi kumapangidwa kuti ayatse zokutira zachitsulo kulikonse komwe ma pixel akuda amafunikira.
Muli wachinyamata, mawonekedwe a ZX 1 okhala ndi mawonekedwe a RS-232 adakupangitsani kumva ngati "mfumu ya dziko".
M'malo mwake, ma Microdrives adapitilira bajeti yanga (yochepa).Ndisanakumane ndi munthu uyu yemwe amagulitsa masewera achifwamba LOL, palibe amene ndimamudziwa.Poyang'ana kumbuyo, ndiyenera kugula Interface 1 ndi masewera ena a ROM.Zosowa ngati mano a nkhuku.
