Hollywood CA. >les@rfx.rfx.com >http://www.rfx.com/folks/les ------------------------------------------------------ Sorry, Les, but it is clear that you don't come here often, do you? The PC printer port can be used quite effectively for many large-scale interface tasks with a minimum of knowledge by simply not treating it as a printer, and by ignoring those BIOS and DOS routines, and instead, simply treat it as three I/O addresses that have their bits mapped directly to the pins of the connector, though some are logically inverted, logical vs voltage, that is. This information is available in the several parallel port FAQ files that are accessible on many ftp and web sites. My ftp sites and their mirrors on other continents are listed in my .sig . The filenames there of note are: ibmlpt.faq (the famous and most thorough one by Zhahai Stewart), krislpt.faq (a short reminder for old hands), and tomlpt.faq , which is the beginners tutorial with examples of programming the parallel port, even in BASIC ! And the idea of interfacing to SCSI bus is not at all outrageous, as it HAS been done. Yes, it needs a driver, but the writing of one is not so difficult a task as it might seem! I believe there has been talk of one in TCJ of late! -Steve Walz rstevew@armory.com -- -Steve Walz rstevew@armory.com ftp://ftp.armory.com/pub/user/rstevew mirrored: ftp://ieee.cas.uc.edu/pub/electronics/faqs/ftp.armory.com and Europe: ftp://ftp.cised.unina.it/pub/electronics/ftp.armory.com and Oz: ftp://ftp.peninsula.apana.org.au/pub/electronics/ftp.armory.com
