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. http://www.blkbox.com/~jdb8042/SmallSys/8bitIDE.html --BN ---------------------------------------------------------------------------- Country Robot "Modular robot components 69 S.

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. Omar Martinez

subscribe IDELIST <g> Count me in please. I would appreciate the info on this interface very much. Gracias, Tim H.

I'm interesting too.

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.
