  • Disk ][ to //c

    From primoduke@primoduke@hotmail.com (Primoduke) to comp.sys.apple2 on Monday, July 14, 2003 20:51:46

    Hi. I'm the happy owner of a Disk ][ unit, and my task now is to see
    if it works. The only problem is that I own a //c and while I now
    it's possible to conect them I don't know how to build an adapter, so
    I need some guide to do it... Any help?

    Thanks!

    I forgot to mention that the cable fron any other Apple II 5'25"
    drive except the DuoDisk will work as an adapter. Maybe someone has
    a dead drive and is willing to part with the cable.

    Yeah, I have an extra Apple 5.25 drive cable I can let ya have.
    I was keeping it for such an emergency, but I can let it go if
    you need it and don't like to solder. ;-)

    Well Bill, thanks a lot for the cable, but the fact is that I live in
    Argentina and it could be a little bit complicated... and since A2's
    were quite rare here, I'll try to build one by myself (Is this english expression used OK??). Anyway, thanks Wayne and Bill for your help!

    Ok, have fun, but you know where a cable is when you're
    tired of trying to fry your drive. Just kidding. Good Luck.
    Yes, your English is just fine, had no problem understanding
    you. ;-)

    Well....Hello again. It seems that things are no always as easy as one
    would like them to be!! So... I need of your help again.
    Besides the pin to pin table Wayne gave me to build the cable, I've
    searched for some extra info on the net and I've found other people's
    tables, but I've found some discrepancies regarding to the voltage
    lines..

    Here are them, where Table 1 is Wayne's, Table 2 is from a post on
    this newsgroup back on 9 Feb 92 and Table 3 from another post on 28
    Mar 95


    Table 1 Table 2 Table 3
    =========== =========== ===========
    20p 19p 20p 19p 20p 19p
    --- --- --- --- --- ---
    1 ----- 1 1 ----- 1 1 ----- 1 GND
    2 ----- 11 2 ----- 11 2 ----- 11 PHASE A
    3 ----- 2 3 ----- 2 3 ----- 2 GND
    4 ----- 12 4 ----- 12 4 ----- 12 PHASE B
    5 ----- 3 5 ----- 3 5 ----- 3 GND
    6 ----- 13 6 ----- 13 6 ----- 13 PHASE C
    7 ----- 4 7 ----- 4 7 ----- 4 GND
    8 ----- 14 8 ----- 14 8 ----- 14 PHASE D
    9 ----- 5 9 ----- 5 9 ----- 5 -12V
    10 ----- 15 10 ----- 15 10 ----- 15 WRITE REQ
    11 ----- 6 11 ----- 6 11 ----- 6 +5V
    DIF!!> 12 ----- n/c 12 ----- 6 12 ----- 16 ## +5V
    DB19-pin16= n/c
    13 ----- 7 13 ----- 7 13 ----- 7 +12V
    14 ----- 17 14 ----- 17 14 ----- 17 DRIVE ENBL (Drive One) DIF!!> 15 ----- 8 15 ----- 7 15 ----- 8 ## All= +12V
    16 ----- 18 16 ----- 18 16 ----- 18 READ DATA
    DIF!!> 17 ----- 9 17 ----- 8 n/c ## IDC20-pin17= +12V
    DB19-pin9= Drive2
    DB19-pin8= +12v
    18 ----- 19 18 ----- 19 18 ----- 19 WRITE DATA
    DIF!!> 19 ----- n/c 19 ----- 8 n/c +12V
    20 ----- 10 20 ----- 10 20 ----- 10 WRITE PROTECT
    DIF??> n/c----- 16 n/c----- 16 ??? DB19-pin16= n/c

    So, I'm not sure how exactly build my cable, and since the
    discrepances here are with Voltage lines, I'm afraid to end with a //c
    and a Drive ][ both fried like eggs, and remember how difficult to
    find these machines are here in Argentina! So here comes another
    question: why the IDC has four pins with +12v: are they for different
    purposes? Or it's just the same if I connect the +12V pin on the DB 19
    (pin 7) to any +12V pin on the IDC 20 (pins 13, 15, 17 and 19)??? Does
    the drive ][ need to recive +12v through each of these pins??? And
    finnally, on TABLE 3, IDC20-pin12 <-----> DB19-pin16, should be a
    typing mistake... what do you think?


    Thanks again.

    I went over them very carefully

    On the 20 pin connector pin 12 has no connection, there isn't even wire
    to that pin
    Pin 15 is connected to pin 8
    Pin 17 is connected to pin 9
    Pin 19 is n/c
    On the 19 pin connector pin 16 doesn't even exist so it's definetly n/c


    So, I'm not sure how exactly build my cable, and since the
    discrepances here are with Voltage lines, I'm afraid to end with a //c
    and a Drive ][ both fried like eggs, and remember how difficult to

    If you look at the top of the analog card in your disk II you'll find
    one trace connects pins 13, 15, 17, and 19.

    On the bottom of the Analog card pins 11 & 12 are connected

    So because these pins are connected Tables 1 and 2 are effectively
    identical.
