> Don't remember in the 99 edition, but in the 2000 edition CD-ROM its under > "PicMicro MCU's" and then "Reference Manuals" (its divided in sections, > maybe this is the reason for not a single PDF) I have it in a single PDF document - goodness knows where I got it from though. It's 688 pages long, and is 3.3Mb. I must have downloaded it from Microchips web site, but I can't find it now... I can only find separated sections. If anyone wants a copy of it, I can upload it to the web. Kieran
