Allow using more than one disk #588

Closed larsbrinkhoff closed 6 years ago

According to Rich Alderson, you just have to increase NQS in SYSTEM; CONFIG > to use more disk drive units. @Pul-Ess is running SV with NQS==3.

Add to configuration, build, documentation, etc.

Building an 8-disk ITS runs into a snag under KLH10: Specifying 8 disk image files in the DSKDMP.INI file causes the message at the end of the following to appear:

I have increased KLH10_DEVMAX from 20 to 31, then to 63, in kn10dev.c, with no change in the occurrence of the error message.

Ideas, anyone?

I mentioned it in the other issue: The Makefile system contains an override -DKLH10_DEVMAX=12. Could that be the problem?

larsbrinkhoff commented 6 years ago

Fixed by PDP-10/klh10#28.

larsbrinkhoff commented 6 years ago

I had to do a little bit more to go from two to four RP03 on a KA10. See #1035.
