    When I was a lad, and my brother had a C64, and I bought an Apple //c, he laughed at me because my Apple only went 'beep, beep, beep' while his C64 played music, and had better graphics. Well, the jokes on him now! I can still use my Apple to play Asteroid--now with 64MB!! Geeze, I can load Appleworks into memory like 500 times, and still have room left over!

    Boy, technology sure has come a LONG way!

  4. what is the real life application to this? by sniepre · · Score: 4, Interesting

    just think how much space 64mb is to an apple ][e.... no more flipping disks!

    true the technology of the host machine is slightly outdated but hell.... you could probably fit one's entire software collection onto a single card, and not have to worry about changing a disk. program the flash and just pop it in, run whatever you like.....

    my question is , is there an easy way to access the filesystem other than on an apple?

    The guy that did this had written into the letters section and sent a link to Woz. Woz seemed impressed, understandably so. The funny thing is that this is considered mass storage for the ][e. For those that still put their old apples through the motions, this could save them a lot of disk swapping, as they could more than likely fit their entire software and data library onto a single 64meg card. neat!

    Why? This is easy! I've dreamed of designing my own IDE/PCMCIA/CF board just for this purpose. I have a IIgs and a IIe. The motivation stems generally from the scarcity of mass storage solutions for the IIe -- the UniDisk 3.5 is VERY hard to get your hands on today, and I have yet to see the fabled "SuperDrive" card that lets you use a 1.44MB drive. In the IIgs arena, the Apple High-Speed (or any other) SCSI card is very hard to acquire without fierce competition on ebay.

    Some outfits sell the Focus Drive, which purportedly works with a 2.5" IDE disk... But seeing as how CF has dropped in comparison to a hard drive, and it's smaller, and it generates no(t a lot of) heat, and doesn't make you waste loads of space on the IIe, it has appeal.

    I see the guy uses the same emulation tools I do -- I ported ADT to ProDOS chiefly to get my 6502 mojo working again... and Apple II Oasis is the best IIe emulator out for win32.

    I'll most likely throw my name into the hat for a board... hopefully this is US-based. All the neat AppleII boards seem to originate in Europe for some reason.

    The state owned TV company in NZ (TVNZ) up until very recently (Q4, 2001) used an Apple ][+ or Apple //e to power their Teletext system (a simplex news & info terminal built into most TV's sold in NZ). They've recently upgraded to a Sun Solaris host to provide the same functionality. The reason: they were no longer able to get spare parts and the system did start to become somewhat unreliable.

    So while the system may not have been critical, it did provide a public service, produced revenue and worked moderately well - hardware faults excepted.

    It wouldn't surprise me that much to hear that other organisations still use older technology to deliver a solution. After all, why fix it unless it's broken?

  8. Don't forget the 8GB of the IDE64 :) by mbpark · · Score: 5, Insightful

    It's about time Apples caught up to the Commodore 64 ;).

    IDE64 has given them that ability for a while, since all you need is a CF to IDE adapter, and you can have up to two 8 GB harddrives on a c64, or a few CF cards, or a couple of IBM Microdrives :).

    16GB on that machine is completely nuts. You could quite possibly store every c64 game ever made (which I estimate at over 30,000 .d64 images total) and still have room left over for the applications.

    Of course, you can go for the 8GB HD and a CD-ROM :). Some of those screenshots are pretty nuts. I can't imagine loading the Windows 95 CD-ROM using LOAD"$",8

    Meanwhile, Nate has nearly hacked together an MP3 player for the c64 based on the MAS chip. That, and a quickcam, and a few other things. Look at the C= projects page. That's some wicked stuff.

    Now that's a hacker's machine. Give them enough time and they even get a workalike UNIX with a GUI and IRC client, as well as a 20Mhz CPU, 16MB RAM, and many other cool things. From what I hear, XGA video and PCI are next.

    I always did like these hackers of older systems. I would enjoy seeing those optimization techniques applied to modern code and compilers, especially gcc :).

    ast Update: Jan 17, 2002 - 11:40am CST

    Project Introduction:

    This page describes a project to create an IDE / CompactFlash Interface card for 8 bit Apple II series of computers. The
    card is ProDOS 8 compatible. I did this project over the span of several months. Although it took much longer than
    expected, it was a fun project. This project is very much a case of old technology (the
    Apple II computer) meets new (IDE / CompactFlash cards and Altera CPLDs).
    My reasoning for this project is described in detail in the last section, but suffice it to say, I
    wanted to be able to pull out my old Apple and use it from time to time to reminisce about the
    early days of personal computers. I wanted a reliable way to store my Apple II programs and
    data files for many years to come. Due to the Apple II's floppy drives long term reliability
    prospects and my general laziness, I decided a mass storage device is what I needed.

    If there was enough interest in this project I would love to make a small batch of boards to
    sell to those interested. But I would need at least 10 orders, and it may be hard to find 10 people interested in something
    like this. I can be reached at rich@dreher.net
    Currently I have only built a prototype, which means no extensive testing has been done
    yet.

    The Apple II was an excellent example of an open system, with unheard-of-today
    documentation like system schematics, firmware listings, and peripheral design tips. Indeed
    the only thing that was totally hidden was the source for the BASIC interpreter - "AppleSoft"
    written by giga-monopoly Microsoft. In the spirit of the Apple II this project is completely
    open.

    Project Definition:

    A CompactFlash/IDE Interface for 8 bit Apple II family of computers
    Support for up to 64 Meg, (two ProDOS 32Meg drives)
    On board EPROM for the ProDOS 8 driver code
    Allow booting ProDOS directly from the Interface card (for a floppy-less system)
    Current version of driver code requires a 65C02. (IIe Enhanced or later)

    Project Prototype Hardware:

    My first prototype used no discreet 74HCTxxx series parts and all logic was in the CPLD, but due to several unrelated
    problems with construction and the consumption of all PLD resources, I decided to build a second prototype with using
    74hct373 parts, this time paying more careful attention to power distribution. I still believe it would be easy to eliminate
    the discreet 74xxx series parts if you used a larger PLD, like the EPM70128S. Although it might not be very cost
    effective.

    Here is the schematic I developed AFTER completing my prototype. That means this schematic has not been tested. If
    you decide to build this project, you might want to check with me for any changes first. Also if you find any mistakes
    please let me know. Project Schematic: ORCAD Capture Format

    If you just want a quick look at the schematic click here to view a 640k jpeg of the schematic. Modem users: sorry about
    the size, but I wanted it to be clear and readable as possible.

    1 - SanDisk CompactFlash 64Meg or 32Meg
    1 - CompactFlash to IDE conversion board - Adtron SDDA-03 available from EMJ Embedded

  10. Re:Why? by Zeinfeld · · Score: 4, Insightful
    How can the parent post be modded down as redundant when it is the 2nd post made? That just makes no sense.

    Perhaps because the question is so obvious it hardly needs to be stated.

    The IDE controller/emulator in the CF card is almost certainly many times faster and more powerful than the Apple II.

    Still I can see a reason for building a device like that. The Apple ][ disk drives were 5 1/4" and sloooooow. Maintaining them is tricky and the media is rapidly reaching its sell by date. The interface would be worth it simply to be able to take a library of Apple ][ floppies and read them onto a modern media.

    The apple II might be somewhat defunct, but there are still important bits of data stored on Apple II disks, like experimental results, audit reports and the like. The kind of information that you simply don't want to lose. Unless perhaps your accountants are you know who and your tax strategy consists of forming 861 shell companies and making large campaign contributions...
