      I still have to go though what I am bringing to trade or sale or whatever,

      But I expect to bring a bunch of s100 cards (I.e. disk controller, Winchester controller, static ram and stuff like that)

      But what I know I will bring is a 6502 S100 CPU card from 1975/76, hayes micro modem for apple II, misc apple II printer cards and a few other items like that. Basically I need to clear out some shelves of cards that are just sitting around doing nothing that I don't really need.

      One thing I am looking for though is a 558 A/D converter chip with an early 1978 date code or earlier for my rev 0 Apple II.

      Cheers,
      Corey

      ... Do you mean AD558? I have quite a few of those, dunno if their date codes are early enough for you. Sadly I think Dan has already headed east. If you

        Do you mean AD558? I have quite a few of those, dunno if their date codes
        are early enough for you. Sadly I think Dan has already headed east. If you
        don't end up finding one, let me know and I'll go check date codes...a DIP is
        easy to drop in the mail.

          I'm losing track of the Corey's on the list! I'm very interested in learning more about the S100 6502 card you're bringing, and if it's for sale/trade, I'm even more interested. Sorry I won't be on hand for the weekend, but I'd love to know more.

          Thanks,
          Jack

            ... I think he s looking for an LM558. It s a dual (or quad) LM555 timer used on the joystick port I think. Tom

              ... Ahhhh. Well he said A/D converter, and I know I have a bunch of Analog Devices AD558s...which, upon further thought, are D/A converters anyway, not A/D

                Ahhhh. Well he said A/D converter, and I know I have a bunch of Analog
                Devices AD558s...which, upon further thought, are D/A converters anyway, not
                A/D converters!

                At any rate, I do have one or two NE558, but I don't know offhand where
                they are at the moment. Sorry Cory!

                I think your right. Next times need to pull my glasses out to read the letters on the chip or look at the schematic. When i was figuring out what i needed, I

                  When i was figuring out what i needed, I just put "558 IC" into my eBay app on my phone and got back it was something different than just a quad timer.

                  I guess now I maybe able to find one with the correct date.

                  Sometimes technology doesn't make it easier it creates work or confuses you.

                  Thanks,
