And yes set cpu idle was specified on both, in fact the ini files are identical except for network adapter name changes. sampsa On 31 Dec 2012, at 21:41, Cory Smelosky <b4 at gewt.net> wrote: On 31 Dec 2012, at 14:40, sampsa at mac.com wrote: On 31 Dec 2012, at 20:46, Cory Smelosky <b4 at gewt.net> wrote: On 31 Dec 2012, at 08:26, sampsa at mac.com wrote: I noticed that Linux SIMH is about twice as fast on OS X.

There s something else going on here. I m not sure who originally analyzed the file to decide that the format was Stream-CR (although given that the analysis was done on RSX, we can probably guess :-) >On 2012-12-31 14:59, Brian Schenkenberger, VAXman- wrote: >> Johnny Billquist <bqt at softjar.se> writes: >> >>> On 2012-12-31 08:08, sampsa at mac.com wrote: >>>> Funny thing about LEGATO's INFO.TXT - my parser looks for the .BEGIN-HECNET-INFO tag and deletes all text after that. >>>> >>>> I should probably make a manual HLP file for LEGATO, Bob you OK with that? >>> >>> LEGATO's INFO.TXT have real yucky file attributes and a real yucky >>> file format. :-) (What on earth was used to produce it???) >> >> Stream_CR typically surfaces with files coming from WEENDOZE. > >Ah.

Yes, CONVERT on VMS is perfectly happy to convert the original file. FWIW, that's how I created the "conventional" variable record length version that RSX likes too. Then, it *WAS* a Stream_CR file! And FWIW, on VMS even EDT has no issues editing the original file. And also, ANALYZE/RMS finds no errors in the original file's format or contents.
