                      Ahoj Zdenku, <br>
                      <br>
                      je to pech, ale zrovna muj Sharp zrejme opravdu
                      pochazi ze zatopeneho bloku Fukusimy :(<br>
                      <br>
                      Termokamera je zajimavy napad, nicmene vyvoj
                      situace je takovy, ze po chvili se mi zvednul
                      odber desky cca o 1A a to i kdyz jsem vyndal z
                      patic CPU i obe ROM. Dale 3 z 8 pameti topi tak,
                      ze na nich po par sekundach nejde udrzet prst,
                      takze veskera mereni se
                      ted snazim delat co nejrychleji.<br>
                      <br>
                      Prozatim jsem zjistil:<br>
                      <br>
                      1) CPU ma /RESET = 0. Piskatkem jsem zjistil, ze
                      signal do tohoto pinu je priveden z 73LS08, coz je
                      2 vstupovy AND. Jeden vstup prijima pulz z
                      resetovaciho tlacitka - ten je OK a ma hodnotu 1.
                      Druhy vstup je zrejme EXT_RESET, ma hodnotu 0 a
                      pochazi kdovi odkud
                      - na GDG jsem ho vsak piskatkem nenasel. <br>
                      <br>
                      2) Nektere pameti HM4864-P2 topi jako blazen.
                      Laboratornim zdrojem poustim do desky 5V, nicmene
                      na napajecich pinech tech pameti to dela 4.45V.
                      <br>
                      Na pameti, ktera zrejme topi nejvic:<br>
                      <br>
                      Din = 2.60<br>
                      /WE = 2.54<br>
                      /RAS = 2.82<br>
                      Dout = 2.61<br>
                      /CAS = 2.68<br>
                      <br>
                      A0 - A7 = 2.8 - 3.01<br>
                      <br>
                      Uroven TTL by mela byt pro 0 v rozpeti 0 - 0.4 V a
                      pro uroven 1 by mela byt nad 2.4V ... Tedy vse by
                      melo byt v urovni 1.
                      <br>
                      <br>
                      Pichnul jsem na RAS a CAS osciloskop, ale nic tam
                      nekmita.<br>
                      <br>
                      3) V podstate nejhorsi co se muze stat je to, ze
                      bude v haji GDG. To ma 60 pinu ke kterym bohuzel
                      neni neznam zadny popis. Zmeril jsem, ze do
                      socketu CPU leze 3.5MHz. Naslepo jsem zkusil
                      pichnout osciloskop na konektor, ktery slouzi pro
                      krmeni video modulatoru
                      a na pinech 4 a 5 vidim 15.7kHz a 60Hz. GDG se
                      tedy tvari tak, ze alespon delicky signalu jsou
                      OK.<br>
                      <br>
                      Bez schematka, ci alespon rozvrzeni spoju se v tom
                      strasne spatne hleda. Kdyz pominu tu vysokou
                      teplotu na tech pametech, tak jedina zjevna chyba
                      je zatim to, ze je ta deska neustale v resetu, tak
                      se pokusim nejak zjistit kam je pripojeny 10. pin
                      toho 74LS08
                      resetovaciho hradla. Vic mne prozatim nenapada. <br>
