[HECnet] ANF10 network --> Anf10 KL<>KS + DN200 --> DN200/DN20 parameters

[R. Voorhorst]

The DN200/DN20  actually supports 5 Dmc class sync lines with some limitations with number of buffers per line; the system is unmapped i.e. only 28 kW available and only 5 concurrent sync lines of one class will fit comfortably within an otherwise  maxed combination of terminal lines and peripherals.
I use the Dmc's for that as they will communicate with every class of sync interfaces, so with Dups as well.
Mixed varieties of sync lines diminish the max achievable active number of lines.
Theoretically one can have more lines per controller and more controllers, but memory constrains what will work. I have not tried Dup's yet for exceeding the pseudo standard of 2 lines.

 Yes, please!

 And does your DN200 support 4 synchronous lines?  Did you modify that too?  The ANF10 manual says it only supports two.

Thanks,
Bob

Reindert,

Would you share the patches to Tops10/simh to support the 4 DUP-11's?
