Hi, A few more things added. I put up the rest of the RT-11 System Reference Manual (Appendix), the RT-11 System Message Manual, and jpeg color scans of the 1960 Electronics Illustrated article "Build An Electronic Computer" in the "Miscellaneous" document section. I have a few more things to OCR, including the RT-11 Software Support Manual, Fortran Notes, etc. In the next few days... www.retrobytes.org Cheers, Aaron
