I am not sure, but perhaps that is one advantage of an
emulator. Since
there
is absolutely no hardware involved (well 99% of the time), many of those
questions
do not even arise, let alone need to be solved.
Yes, but there isn't something
you can actually touch. It's just an
emulator... BTW I just had a crashed RK05 a few minutes ago - had to
clean head and disk... now running fine again...
I must accept you answer, but I am left confused. Is
FPGA hardware so
much slower than
the CPU for a current Intel or AMD based PC?
Hey, it's reconfigurable logic!
And yes, it's slower than a multi-GHz PC
processor with all it's tricks to execute code even faster than you assume.
There might be FPGA hardware that can run as fast as 400-500MHz I
suppose - but that's still far from a modern PC cpu.
On the other hand it's no problem to put a few more pdp8 CPUs into one
FPGA... FPGAs can do everything in parallel - and they consume less
space and power than the whole simulation environment.
Thank You. You also It is sort of fun playing with
the old software
when there is no deadline to finish the code.
:-) Of course! Currently I'm
still worrying about that RK05 disk I'm
just dumping... Hope it gets through before I have to clean it again...
There is still some noise - but no read errors so far...
Best wishes,
