I am like speechless :-)
I crashed the DEC-20 because of such long transfer until
a DEC engineer told me why after we sent them a crash dump tape.
Essentially I was told that the tty input queue was
very short since nobody was going type in very quickly and
I was overflowing it!
Oh, the joy of "mainframe" programming!

I feel a little dizzy.
Care to comment where such emulator will be available?.
I wonder if those DECUS tapes were kept on-line somewhere,
like InterLisp, etc.. Not that I want to run them earnestly, but
some playful programs might still be fun to see how
it runs on a fast PC.
(Oh, the memory limit hurts still.)

Thank you again for your contribution over all these years.
