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

[Timothe Litt]

A couple of other things come to mind (naturally, after pushing 'send'):

Initialization will load/verify the microcode.  That has to work.

After setting RUN and the interrupt enables, expect base-in and 
control-in command to establish the DUP CSR address, buffers, line 
mode/enable.  These require that the KMC respond to KMCRQI by initiating 
an A vector interrupt.

Besides RDIO and WRIO, there are bit test (TIOx) , bit set (BSIO) and 
bit clear (BCIO) instructions that also touch the KMC.

For better directed hints, I'd need more detail on what is and isn't 
happening.

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