Interesting project. This is one I plan to work on one day.

You need two things:

1) The data book for your disk drive. Call the manufacturer.
2) The ATA (read IDE) disk interface standard. Not sure where to get this
  one from.

IDE drives are really just an extension of the AT bus. The paddle cards
(before the advent of multi-IO) were simply buffer chips between the
bus and the drive. The 17C42 (or even an 8 bit PIC for the matter) can
simulate the same interface.

Also there's a BYTE magazine article (early nineties) that described the
process.

But you sir are not off the hook (so to speak):

1) Tell us how you are interfaceing to the phone line including ring
  detection? Someone pointed out to me that the old trick of using a
  neon lamp coupled to a photodector is quite effective.

2) How are you converting audio to digital and vice-versa. Are you going
  to use a CODEC. If so which one?

3) How are you programming the 17C42? I'm in the process of developing a
  16C84 based RAM loader for my 17C42 development board. It'll give quick
  development turnarounds (no eprom erasing) and avoid all the programming
  hassles (spending bucks on a programmer is a hassle).

Anyway I have a 40 Meg IDE drive waiting to go into a project just as
you describe. So let us know what's going on!

Later,

BAJ

A while ago there was some discussion on interfaciung PICs to IDE drives.
Here's a page that shows how it can be done for several 8-bit processors,
including the Z80 and 6809. Perhaps this will be of some help.

Did anyone get anywhere with the ide to pic interfacing????

John:
I have some information about the IDE interface that I find some time ago....If my memory don't fail, It's basically use an 82C55 and a 74LS04 to connect directly to the Hard Disk over an 8 bits data bus.
Also, in the document are a description of the signals pins (In & Out).
If you are interested on it, I could search that info in house and sent to you... or everybody...

Best regards.

       Or, how about PIC to floppy interface?  Ideally, without using
additional hardware (like an FDC).  I'd like to have an EIA232 controlled
floppy.

I, for one, would love to see the specification.

Not sure if any info has been sent off list (if so please forward to me) but
otherwise here is the info I have found while looking for similar stuff:

ftp://fission.dt.wdc.com/pub/standards/x3t13/project/
   -Technical documents on ATA/ATAPI and other syandards. Not sure what all
the files are but I know the following
           d1321r1a = AT Attachment with Packet Interface - 5 (ATA/ATAPI-5)
Standards
   - There are also documents on ATAPI over IEEE 1394 (=Firewire = very
fast (500Mb/s from bad memory) USB) but I don't know which one.

http://www.nomad.ee/micros/
   - Info on an 8052 IDE interface. Started off using a PIC but changed due
to PIC limitations. Hardware interface fully implemented, software interface
partially interfaced.

Hope these help.
Thomas Brandon.

For a complete treatment of IDE interfacing to 8-bit CPUs (particularly the
Z80 family), check out issues 56, 63, 64, and 66 of The Computer Journal
http://www.psyber.com/~tcj/. There is a simple IDE interface for the Z80
called GIDE (Generic IDE). It should be possible to adapt it to other 8-bit
processors.
