Titolo: Macintosh 128 (lungo)

Salve sono Marco di Cesena.......ho recuperato recentemente
un MAC128 (il cubetto per intenderci...)
Portato a casa e ripulito dello sporco (ottima plastica e tornato come
nuovo)
all'accensione mi presentava solo una iconcina con mac triste (!) e dei
numeri sotto......
Niente altro anche il floppy non dava segni di vita.......
Grazie alla fiera di rimini mi sono procurato un cacciavite per quelle
dannatissime viti torx a cinque punte che lo chiudono...un po' di
pazienza e di fortuna e riesco ad aprire il coso......
Un rapida occhiata alla carrozzeria......con le firme dei progettisti !
Ottima l'ingegnerizzazione di questo piccolo mac....chi l'ha pensato ha
avuto
un occhio di riguardo anche per il povero tecnico dell'assistenza !
Dunque sfilati due connettori e la scheda madre puo' essere comodamente
estratta dal fondo ....
Un rapida ripulita col solito pennellone e con grande sorpresa scopro che le
ram (sospette
del guasto) sono tutte zoccolate.....e soprattutto sono delle normali 41256
Da una scheda di un vecchio pc che si offre come volotario provo il
trapianto
ed al secondo tentativo il mac si rianima.....la prima cosa che fa' e'
riposizionare il
floppy che probabilmente si era bloccato in fase di eject dopo qualche
secondo
parte il video con un mac che mi chiede un dischetto !
Ora che ho richiuso il tutto le note dolenti....putroppo la macchina in
questione e' senza tastiera
e mouse......secondo voi e' possibile adattare una tastier aper pc ??? per
il mouse dato che e'
seriale potrebbe essere compatibile con un seriale per pc (eventualmente
modificando il cavo )??
Ok grazie a tutti coloro che mi risponderanno e scusate se vi ho annioato
con le chiacchere !

*** Jesus is coming, everyone look busy. ***

 Non sarei tanto ottimista, ne' per la tastiera ne' per il mouse.
Basta una tastiera adb per un vecchio Se/Classic/Se/30. Lo stesso per il
mouse.
Dovrebbe cannibalizzare qualche vecchio Mac.
Ciao
Enrico

 modificando il cavo )??
un po di info varie sui mac "compatti" sono nel mio sitino
http://china.sincretech.it
di adattare non ho provato mai ... mouse e tastiere sono uguali tra tutti i
compatti ( 128/512/512ke/plus ) ma oltre non mi risulta...  c'e' carenza di
mouse (vero luigi?)
il MacOS 6.x  (ultima della serie 6 e' la 6.0.8) si recupera da internet...
il piu e' fare il floppy dopo...
tenere presente che se e' un 128 "reale" (non upgradato) ha un drive da 400k
(... e rom da 64k)....

 Bisogna che si procuri quelle per Mac 128, 512, Plus.
Azzz, un'altro tipo di tastiera.......che fantasia alla Apple :-)
Ciao
Enrico

 se interessa posto l'elenco.
Posta, posta. :-)

Da "Apple Error codes '98":
        Macintosh: "Sad Mac" Error Code Meaning
        Article ID:  7748
        Created: 7/2/91
        Modified: 9/9/97
        The particular error code that appears with the "sad Macintosh" is not
        as important as WHEN it occurs. If the Macintosh can start up from a
        different system diskette, then the problem is probably with the system
        software on the other disk. System problems are usually identified when
        you get a "happy Macintosh" face and the "Welcome to Macintosh" screen
        before the "sad Macintosh."
        If the "sad Macintosh" face appears immediately at power up, that usually
        suggests an issue with the logic board or memory. Try starting up from a
        floppy disk before assuming it's a hardware problem.
        Sad Mac Error Codes Description
        On the Original ROMs (Macintosh 128k, 512k, 512ke, Plus):
        When you press the interrupt button on the side of your Macintosh when
        starting up, you should get a sad Mac icon with '0F000D' and some bits
        cycling under the icon indicating it is performing a memory test.
        This numeric code is in two parts:
            • The first two characters are the class code. The class code tells
              what part of the diagnostic program found the error.
            • The second four are the sub code. The sub class code tells what the
              error was. In the case of a bad RAM chip, the sub class identifies
              the bad chip (this was very helpful to homegrown upgraders).

        Macintosh SE & Macintosh II ROMs: 
        The Sad Mac error codes have been changed to incorporate additional
        power for testing and to support the 32-bit world. Generally, the
        same codes are used for 68000 exceptions as the Macintosh, however
        they are displayed differently.
        Traditional
        The traditional Macintosh error codes are displayed like this:
        0F0003
        Where F indicates an exception occurred, and 3 indicates an illegal
        instruction occurred. On the Macintosh SE and II, the display would
        appear:
        0000000F
        00000003
        Note: 0000003 is a hex number.
        Power On
        The new power-on error codes have the following format:
 
        XXXXYYYY
        ZZZZZZZZ
        Where XXXX is internal test manager state information (ignore this), 
        YYYY contains codes that indicate either an exception code, or the
        test number for a power on test failure. The ZZZZZZZZ code contains
        additional failure information to help track down the problem.
        YYYY Error Codes:
        $0001   The ROM checksum test failed. Ignore the Z field.
        $0002   The first small chunk of RAM to be tested failed. The Z field
                indicates which RAM Bit(s) failed. This small chunk of RAM is
                always in Bank B.   
                Example:   $AABBCCDD
                           AA=8 bit mask for bits 31-24
                           BB=8 bit mask for bits 23-16
                           CC=8 bit mask for bits 15-8
                           DD=8 bit mask for bits 7-0
        $0003   The RAM test failed while testing bank B, after passing the chunk
                tested for code $0002. The Z field indicates which bits failed as
                in code $0002.
        $0004   The RAM test failed while testing bank A. The Z field indicates
                which  bits failed as in code $0002.
        $0005   The RAM External addressing test failed. The Z field indicates a
                failed address line.
        $0006   Unable to properly address the VIA1 chip. The Z field is not
                applicable.
        $0007   Unable to properly address the VIA2 chip (Macintosh II only). 
                The Z field is not applicable.
        $0008   Unable to properly access the Front Desk Bus. The Z field is not
                applicable.
        $0009   Unable to properly access the MMU. The Z field is not applicable.
        $000A   Unable to properly access NuBus. The Z field is not applicable.
        $000B   Unable to properly access the SCSI Chip. The Z field is not
                applicable.
        $000C   Unable to properly access the IWM chip. The Z field is not
                applicable.
        $000D   Unable to properly access the SCC Chip. The Z field is not 
                applicable.
        $000E   Failed Data Bus test. The Z field indicated the bad bit(s) as a 
                32-bit mask for bits 0-31. This may indicate either a bad SIMM or
                data bus failure.
        $000F   Reserved for Macintosh compatibility.
        $FFxx   A 680xx exception occurred during power on testing. 
                The xx indicates the exception:
                $01  Bus Error
                $02  Address Error
                $03  Illegal Instruction Error
                $04  Zero Divide

        Macintosh Portable ROMs:
        The bootup code in the Macintosh Portable contains a series of startup
        tests that are run to ensure that the fundamental operations of the
        machine are working properly. If any of those tests fail, a Sad Mac
        icon appears on the screen with a code below that describes what failure
        occurred. Here is a typical example of a Sad Mac display with an error
        code below it:
        SAD MAC CODE
        05460203   =   (D7.L)
        000OB6DB   =   (D6.L)
        The two codes are actually the contents of the two CPU data registers
        D6 and D7. The upper word (upper 4 hex digits, in this case 0546) of 
        D7 contains miscellaneous flags that are used by the start-up test
        routines and are unimportant to just about everybody except a few test
        engineers within Apple. The lower word of D7 is the major error code.
        The major error code identifies the general area the test routines were
        in when a failure occurred. D6 is the minor error and usually contains
        additional information about the failure, something like a failed bit
        mask. 
        SAD MAC CODE BROKEN DOWN
        Test Flags    Major Error
        0546          0203
        Minor Error   Minor Error 
        0000          B6DB
        The major error is further broken into the upper byte that contains
        the number of any 68000 exception that occurred ($00 meaning that no
        exception occurred), and the lower byte that usually contains the
        test that was being run at the time of failure. If an unexpected
        exception occurred during aparticular test, then the exception number
        is logically ORed into the major error code. This way both the exception
        that occurred as well as the test that was running can be decoded from
        the major error code:
        SAD MAC CODE FURTHER BROKEN DOWN
        68000 Exception    Test Code
        02                  03
        In this example, the code says that an address error exception ($0200)
        occurred during the RAM test for Bank A ($03); $0200 ORed with 
        $03 = $0203.
        Major Error Codes
        Below is a brief description of the various test codes that might 
        appear in the major error code:
        **Warning**: Some of these codes may mean slightly different things in
        Macintosh models other than the Macintosh Portable. These descriptions
        describe specifically how they are used in the Macintosh Portable.
        $01   - ROM test failed. Minor error code is $FFFF, means nothing. 
        $02   - RAM test failed. Minor error code indicates which RAM bits
 
                failed. 
        $05   - RAM external addressing test failed. Minor error code 
                indicates a failed address line. 
        $06   - Unable to properly access the VIA 1 chip during VIA
                initialization. Minor error code not applicable. 
        $08   - Data bus test at location eight bytes off of top of memory
 
                failed.  Minor error code indicates the bad bits as a 16bit
                mask for bits 1500. This may indicate either a bad RAM chip
                or data bus failure. 
        $0B  -  Unable to properly access the SCSI chip. Minor error code not
                applicable. 
        $0C  -  Unable to properly access the IWM (or SWIM) chip. Minor error
                code not applicable. 
        $0D  -  Not applicable to Macintosh Portable. Unable to properly access
 
                the SCC chip. 
                Minor error code not applicable. 
        $0E  -  Data bus test at location $0 failed. Minor error code indicates
                the bad bits as a 16bit mask for bits 1500. This may indicate
                either a bad RAM chip or data bus failure.
        $10  -  Video RAM test failed. Minor error code indicates which RAM bits
                failed. 
        $11  -  Video RAM addressing test failed. Minor error code contains the
                following:        upper word    =       failed address (16-bit) 
                           msb of lower word    =       data written    
                           lsb of lower word    =       data read
                Data value written also indicates which address line is being
                actively tested. 
        $12  -  Deleted 
        $13  -  Deleted 
        $14  -  Power Manager processor was unable to turn on all the power to
                the board. This may have been due to a communication problem
                with the Power Manager. If so, the minor error code contains a
                Power Manager error code, explained in the next section. 
        $15  -  Power Manager failed its self-test. Minor error code contains
                the following:  
                         msw  = error status of transmission to power manager.
                         lsw  = Power Manager self-test results (0 means it
                                passed, non-zero means it failed) 
        $16  -  A failure occurred while trying to size and configure the RAM.
                Minor error code not applicable.
        Minor error codesPower Manager Processor Failures
        If a communication problem occurs during communication with the Power
        Manager, the following error codes will appear somewhere in the minor
        error code (usually in the lower half of the code, but not always):
        $CD38   Power Manager was never ready to start handshake. 
        $CD37   Timed out waiting for reply to initial handshake. 
        $CD36   During a send, Power Manager did not start a handshake. 
        $CD35   During a send, Power Manager did not finish a handshake.
        $CD34   During a receive, Power Manager did not start a handshake.
        $CD33   During a receive, Power Manager did not finish a handshake.

 pensano diversamente)
Per caso, non avresti anche i codici per i Classic/SE/Se30 ?
Grazie
Enrico

 Per caso, non avresti anche i codici per i Classic/SE/Se30 ?
Ma ci sono! "SE/Macintosh II" comprende l'SE/30 e i Classic.
Ma ti conviene cercare "Apple Error Codes" in rete, e' facile
che ci siano elenchi anche piu' dettagliati.


 che ci siano elenchi anche piu' dettagliati.
Ok. Grazie
Siamo gli stessi del Ng di mac..... :-))
Ciao
Enrico

system 6.0.3 in rom....
Solo il classic o anche altri modelli?

modificando il cavo )??
Una volta ho letto in qualche sito che sarebbe quasiforse possibile ma non
c'era nulla di preciso. Se scopri qualcosa faccelo sapere.

 Arriva...
Tnx. :-)
