[Simh] TOPS-20 Source with KMC11 Driver Code?

[Timothe Litt]

This wouldn't be a -10 coding issue. It worked on the real systems.

The CR's data transfer in simh may be broken due to the bugs discussed.  
But the 'unavailable' status is probably that GALAXY has control of the 
device and expects to spool data via CDRIVE/SPRINT, which may need to be 
started.

See the operator's and galaxy batch documentation. (e.g. 
http://www.textfiles.com/bitsavers/pdf/dec/pdp10/TOPS10_softwareNotebooks/vol02/AA_H374B_batch.pdf 
http://www.textfiles.com/bitsavers/pdf/dec/pdp10/TOPS10_softwareNotebooks/vol17/AA-H599C-TB_OperCmdLang.pdf)

One of these days I'll might build a monitor with CDR support and try it.

This communication may not represent my employer's views,
if any, on the matters discussed.

I have plans to teach myself MACRO-10 and have a look at the driver and the simh code like I did with the CR for the '11 and the VAX, but I can't commit myself on a date to do it (I am having too much fun with DECNET-OSI at this moment).
