I was looking at some of the diagnostics on the KLAD pack
http://pdp-10.trailing-edge.com/klad_sources/index.html
and I notice that this one (DAKAA - basic instruction test) has a bunch of
interesting output at the end of the .SEQ file
http://pdp-10.trailing-edge.com/klad_sources/01/klad.sources/dakaa.seq.html
The first part is just the diagnostic operating instructions and the second
part is the MACRO-10 listing, but at the end there's the output from what
appears to be a KA10 simulation. The header on each listing page says
"KASIM VER 0.2 19-JAN-77" - did DEC actually write a KA10 simulator ? And
it's apparently more than just a simple instruction simulator too, because
for each instruction there's a complete trace with all the internal time
states and internal register contents for the KA10. It must be an attempt
to model the internal architecture of the KA CPU.
Does anyone know any more about this program? Does anyone have a pointer
to the source for it? Tantalizingly there's a KASIM.SAV on the KLAD pack,
but that's all.
