Hello group: I have a person whom was kind enough to post the PDF excerps from scanning "Practical Microprocessors" which is the lab manual for the HP 5036 microprocessor trainer.. I scanned the schematics, rom listing and a few other pages. You can find it on Dave's site here http://www.neurotica.com/misc/practical_microprocessors.pdf be warned that in order to make it worth while to read its 125 megs I suggest that you print it out the 40 so pages. I printed it to make sure that its readable. Spent a day to scan it and build the pdf so I hope those with the trainer and have no manual will find it usefull. Jim
