Thanks Al, 3 less to scan :~) A question about the naming scheme of the files. As example, let's take this one: AC-E246B-MC CZRLEB0 RL01/RLV11 PERF EXERCISER According to bitsavers that would become something like this: AC-E246B-MC-RL01-RLV11PERF.pdf where the last part gives a brief indication what the xxdp is used for. I wonder if the "AC-E<number>-MC" is useful, but I have no experience in this field, so that part could be very useful but I don't know that. Also, I have a few 'patch' sheets, and their name start with "AF". That would mean that they would not remain together with the original xxdp in a alphabetic list. Furthermore, is the xxdp name (CZRLEB0) not more meaningfull? In that case the file name would become: CZRLEB0-RL01-RLV11-PERF.pdf I'd appreciate any good advice before I start next week. If you can give me (private of course) a URL, I will upload them as I scanned each one of them as .pdf - IF you can use them on bitsavers. - Henk, PA8PDP.
