I'm suspecting the opposite.. I went through all of the comments in notes.txt about hand written corrections and read through the code to see if they make sense or not and it seems like all of the corrections did make sense in the code and the original code that they replaced did not. I updated the code to reflect this and added comments to the notes file. btw, there are still a bunch of unresolved symbols in the low address vector tables.. I took a look at the assembly memory dump last night (and also committed code in tools to convert the a.out to a bunch of simh deposit commands). > I had to add KE11A support to simh; I mostly copied the code from > apout. This discussion of hardware is making me wonder -- does this nail down the hardware? The 1ed manuals mention tht they ran on a 24kbyte pdp 11/20, but that they were eying an 11/45. My reading of the code was making me lean towards the original 11/20 configuration, but it sounds like some of these features might be present in the 11/40 or 11/45? > I'll put a tar file on my web site with the modified simh source. speaking of modifying simh, we may have to map one of the similar serial devices in at the dc11 address to support ttys. simh doesn't support the DC-11, but when I asked on the simh mailing list someone mentioned that one of the existing devices is very similar with less support for modem control lines. > -brad Tim Newsham http://www.thenewsh.com/~newsham/
