Interesting. I wonder if the documentation has gotten dropped somehow. Either that or I’m still being blind. As far as I can tell, the GITHUB repository lacks such files. https://github.com/simh/simh/tree/master/ The v3.9-0 source at Trailing-Edge does as well. http://simh.trailing-edge.com/ The v3.0 source on the other hand has a vax_doc.txt under the VAX subdirectory. I’m using the SIMH build on Ubuntu in a VM. That appears to be v3.8-1, and oddly enough you can do “man vax” which points you to where the doc’s are. Here are some of the applicable looking ones. -rw-r--r-- 1 root root 34768 Mar 2 2007 simh_magtape.pdf -rw-r--r-- 1 root root 188726 Feb 8 2009 simh.pdf -rw-r--r-- 1 root root 3501 May 27 2008 vax780_bug_history.txt -rw-r--r-- 1 root root 107942 Feb 8 2009 vax780_doc.pdf -rw-r--r-- 1 root root 117234 Feb 8 2009 vax_doc.pdf And there is the info I was after, in vax_doc.pdf. :-) SET TS0 CAPAC=m It looks like the TK50 emulation is limited to 2GB, so I don’t want to use that. Plus it has details on the large disk sizes using SET RQn RAUSER{=n} that I’d found out about last night, and an RRD40 type that I was unaware of. Next step, installing Linux on a Core i5 box I picked up for $75 recently to run SIMH. If all this works, it will allow me to *significantly* cut my electricity bill, while keeping my VMS data online and accessible. :-) Zane _______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
